Best European Alternatives to SharePoint
Looking for a European alternative to SharePoint? An intranet accumulates everything an organisation knows — procedures, contracts, HR policies, half-finished strategy — and SharePoint puts all of it inside Microsoft 365, with licensing and complexity that grow in step.
These European alternatives cover wikis, document collaboration and full groupware, and every one of them can be run on infrastructure you control.
How we rank these tools — 4-step process
-
1
European ownership, verified
The company is headquartered and incorporated in the EU, EEA or Switzerland, and processes customer data in Europe. A US parent company disqualifies a tool from this page regardless of where its servers are.
-
2
Category fit and hands-on review
What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.
-
3
Compliance and pricing check
GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.
-
4
Position on this page
Placement on this page can be paid, and that can affect which tools appear here and the order they appear in. It never buys a good review: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.
Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Paid placement can affect which tools appear here and the order they appear in. Editorial policy

Key takeaways
- SharePoint Online keeps EU customer data inside the EU and EFTA, and since February 2025 stores support case data there at rest too, subject to documented exceptions — so data location is not the reason to move.
- Microsoft's own legal director told the French Senate in June 2025 that he could not guarantee French data would never reach US authorities, which is the reason that survives.
- SharePoint Server 2016 and 2019 lost support on 14 July 2026 with no extended security update programme announced.
- On-premises SharePoint was the half mass-exploited in July 2025 through ToolShell, so self-hosting is a responsibility rather than a shortcut.
- Stackfield is the only tool here the provider cannot read at all, which is a stronger claim than any residency boundary can make.
Why people leave SharePoint
SharePoint is rarely chosen and almost never loved. It arrives with Microsoft 365, it is already paid for, and it becomes the place documents go because no one selected anything else. That is its strength — nobody has to buy it — and it is also why leaving feels like an argument with procurement rather than a product decision.
The reason organisations start looking is not storage location. Microsoft has gone further on that than any other vendor in this directory: the EU Data Boundary was completed on 26 February 2025 across three phases, and since that final phase the professional services data created when you raise a support ticket is stored at rest inside the EU and EFTA as well.
Two qualifications belong with that, and they are Microsoft's own: customer data and pseudonymised log data are stored and processed inside the boundary while professional services data is only stored there, and the whole commitment is stated as subject to limited circumstances in which data is still transferred outside it.
Even so, for a requirement written in terms of where the bytes sit, SharePoint Online largely satisfies it.
They look because that completeness does not settle the question underneath it. On 10 June 2025 the French Senate asked Microsoft France's director of legal affairs whether he could guarantee under oath that French citizens' data held in Microsoft's cloud would never be handed to US authorities without French approval. He answered that he could not guarantee it. The most thorough residency programme in the industry and its own lawyer arrive at the same place.
- The vendor answered the question itself Microsoft did not dodge the French Senate hearing, and that is what makes it useful. Its own legal director said plainly that a valid US order reaches the company, that Microsoft reviews and contests requests it considers unjustified, and that it cannot promise the outcome. No amount of data boundary engineering changes the corporate law that sits above it. For a ministry, a hospital or a bank, that sentence is the whole risk assessment, delivered by the supplier under oath.
- The on-premises escape route closed in July 2026 SharePoint Server 2016 and 2019 reached end of support on 14 July 2026, and Microsoft has announced no paid extended security updates for either, unlike Windows Server and SQL Server. Organisations still running them are receiving no security patches at all. The supported route is SharePoint Server Subscription Edition, which does still exist — self-hosting SharePoint has not been withdrawn the way self-hosting Jira was — but it is a licensing and migration project, not a decision to leave things alone.
- And self-hosting is not automatically the safer half In July 2025 the ToolShell campaign exploited an unauthenticated deserialisation flaw in on-premises SharePoint, CVE-2025-53770, scored 9.8 and requiring no credentials at all. Attackers pulled ASP.NET machine keys off servers and forged payloads that SharePoint accepted as legitimate. By 24 July, Check Point had counted more than 4,600 compromise attempts against over 300 organisations, and Microsoft had shipped an emergency out-of-band patch. Anyone recommending an on-premises server as the conservative choice should have to explain that month.
- It is a platform where you needed a product SharePoint is a document store, an intranet, a workflow engine, a list database and a permissions model, and in most organisations somebody has spent years wiring those together. That accumulation is the real cost. Teams end up with a site collection nobody can map, permission inheritance nobody dares change, and documents that are findable only by the person who filed them. Several tools on this page do one of those jobs deliberately, and for the department that inherited SharePoint from IT, one job done well is not a downgrade.
What you have to replace, not just match
Before comparing anything, separate the four SharePoint jobs, because no single European tool does all four and pretending otherwise is how these projects stall.
The first is file storage and sync, the drive that OneDrive surfaces. The second is the intranet — news, landing pages, the thing on everyone's home screen. The third is written knowledge: procedures, handbooks, policies, the material that ought to be a wiki and is currently forty Word documents. The fourth is the list-and-workflow layer, the small applications built out of SharePoint lists and Power Automate because asking IT for a real one was harder.
Nextcloud covers the first and a useful slice of the second. XWiki and BlueSpice own the third, from opposite ends. Nothing on this page reproduces the fourth cleanly, and that is the honest sentence this page owes you: if your SharePoint runs on custom lists and flows, budget for rebuilding them rather than migrating them.

How each alternative compares to SharePoint
- Which law reaches it. EU (Germany). SharePoint is run from the United States, so the CLOUD Act obliges the provider to hand over data on a valid order regardless of which country the servers are in.
- Where the data sits. Wherever you host it.
- Source code. Open source, where SharePoint is not: you can read what it does rather than take the description on trust.
Best for: Organisations replacing the whole SharePoint and OneDrive footprint at once
Nextcloud is the answer to the sentence Microsoft could not say in Paris. Run it on your own hardware or with a European managed provider and there is no US corporation in the chain to receive an order in the first place — not a boundary drawn around the data, but the absence of a party who could be compelled. Nextcloud GmbH is in Stuttgart and the software is AGPL.
What you get is broader than a document library. File sync and sharing covers what people use OneDrive and SharePoint libraries for, Nextcloud Talk handles chat and calls, Nextcloud Office edits documents collaboratively, and calendar and contacts complete the working day, with an app marketplace filling in project boards, forms and more. For an organisation that wanted one login rather than one vendor, that breadth is the argument.
The honest costs are operational and comparative. Somebody owns updates, backups and the Friday morning when sync misbehaves, and July 2025 is a reminder that owning a server is a duty rather than a virtue — managed Nextcloud hosting from a European provider is the sane version for most organisations. Feature by feature, Nextcloud Office is competent rather than a match for Word and Excel, and search across a large estate needs attention as it grows.
What Nextcloud does better than SharePoint
- No US corporation holds the data at all, so the question Microsoft declined to answer under oath does not arise
- AGPL-licensed, so the behaviour can be inspected rather than accepted on documentation
- No per-seat licence, where SharePoint arrives inside a Microsoft 365 subscription priced per user
- Files, calendar, contacts, chat, calls and documents in one install rather than five services stitched together
- You choose the hosting country and the provider, instead of choosing a region inside someone else's cloud
Where Nextcloud is a step down from SharePoint
- You own patching and uptime, which is precisely what July 2025 made expensive for self-hosted SharePoint
- Office editing is workable rather than equal to Word, Excel and PowerPoint
- No equivalent of the Microsoft 365 integration that puts SharePoint inside Teams and Outlook
- Nothing replaces SharePoint lists and Power Automate without a rebuild
Standout against SharePoint. It is the only option here where nobody can be served an order for your documents, because nobody but you is holding them.
- Which law reaches it. EU (Germany). SharePoint is run from the United States, so the CLOUD Act obliges the provider to hand over data on a valid order regardless of which country the servers are in.
- Where the data sits. Germany (EU) or self-hosted.
- Source code. Open source, where SharePoint is not: you can read what it does rather than take the description on trust.
Best for: Teams whose SharePoint site is really a schedule kept in spreadsheets
A large share of SharePoint sites exist because a project needed somewhere to live and SharePoint was already there. What actually accumulates is a document library, a status spreadsheet somebody updates on Fridays, and a list of tasks with a date column. OpenProject replaces that arrangement with a system that knows what a project is.
Work packages, Gantt charts with baselines and dependencies, time and cost tracking against budgets, agile boards and a wiki are native rather than assembled, and the wiki is the piece that matters here: project documentation sits beside the schedule rather than in a separate library that goes stale. OpenProject GmbH is in Berlin, AGPL-licensed, free as a self-hosted Community Edition or hosted in Germany from about €5.95 per user per month.
It is not an intranet and should not be sold as one. There is no news layer, no general-purpose document store for the whole organisation, and no equivalent of the Microsoft 365 integration. For a department it replaces a genuine SharePoint use case completely; for a company-wide rollout it is one tool among several.
What OpenProject does better than SharePoint
- Real schedules with dependencies and baselines, where SharePoint offers a list with a date column
- Budgets and cost tracking, which SharePoint has never modelled at all
- German company and German hosting, or your own servers, with no US parent in the chain
- A project wiki beside the plan instead of a document library that drifts out of date
- Costs nothing on your own hardware however many people use it, against a SharePoint that arrives inside a per-head subscription
Where OpenProject is a step down from SharePoint
- Not an intranet and not a general document store, so it replaces one SharePoint use case rather than the platform
- The screens do the job without looking like a modern SharePoint page
- Running a Ruby application yourself is a genuine operational commitment
- Some capabilities sit in the Enterprise edition rather than the free Community one
Standout against SharePoint. It is the only tool here that treats a deadline as something that moves other deadlines, which is what the spreadsheet beside your SharePoint site was doing by hand.
- Which law reaches it. EU (France). SharePoint is run from the United States, so the CLOUD Act obliges the provider to hand over data on a valid order regardless of which country the servers are in.
- Where the data sits. Your own infrastructure, or XWiki Cloud EU.
- Source code. Open source, where SharePoint is not: you can read what it does rather than take the description on trust.
- Independently checked. GDPR.
Best for: Organisations whose SharePoint became a small applications platform
XWiki is the closest thing here to the part of SharePoint that nobody planned: the lists, the registers and the little tracking tools built because requesting a real application was harder than making one. An XWiki page can carry typed fields as well as prose, sets of those pages can be queried, and the application builder lets the department that needs a supplier register or an equipment log build one itself.
The rest is a serious wiki. Fine-grained rights, wired to LDAP and SSO, let one wiki hold material that not every employee should open — the exact thing a lightweight wiki has no way to express, and the exact reason organisations stayed on SharePoint. XWiki SAS has been going in Paris since 2004, ships under LGPLv2.1, and runs either on your own servers or on XWiki Cloud EU at roughly €3 a seat a month.
What it will not do is impersonate a document management system. Files attach to pages rather than living in a managed library with metadata columns, so a SharePoint estate that is overwhelmingly documents should look at Nextcloud first and use XWiki for the written layer. The interface looks its age, which costs you adoption, and the application builder takes real time to learn.
What XWiki does better than SharePoint
- Structured fields inside pages plus an application builder, which is the closest thing here to SharePoint lists
- Granular permissions with LDAP and SSO, so confidential material can live in the same system
- French vendor under LGPLv2.1, fully self-hostable, with no US corporation able to receive an order
- Written procedures live as pages that change rather than as Word files nobody reopens
- Costs nothing on your own server, and roughly €3 a seat on its EU cloud, set against a Microsoft 365 licence per head
Where XWiki is a step down from SharePoint
- Not a document management system: attachments hang off pages rather than sitting in a managed library
- No metadata columns, content types or retention labels of the kind SharePoint libraries carry
- Dated interface, which matters when you are asking people to move off something familiar
- Self-hosting a Java application requires operational capability
Standout against SharePoint. It is the only tool here that can rebuild a SharePoint list as a real small application rather than as a page with a table on it.
- Which law reaches it. EU (Germany). SharePoint is run from the United States, so the CLOUD Act obliges the provider to hand over data on a valid order regardless of which country the servers are in.
- Where the data sits. EU.
- Source code. Closed source, as SharePoint is.
- Independently checked. GDPR.
Best for: Teams whose SharePoint content is technically present and practically unfindable
The complaint about SharePoint is rarely that a document is missing. It is that finding it takes four clicks, two guesses and a message to whoever filed it, and that writing something new means choosing a site, a library and a content type first. Nuclino removes all of that: instant search, instant page loads and nothing to configure before you start typing.
The effect is behavioural rather than aesthetic. When capturing something takes seconds, more gets captured, and a knowledge base only ever succeeds on that one measure. The graph view shows how pages connect, so structure emerges from internal links instead of requiring someone to design a site hierarchy before any content exists — which is the task that quietly kills most SharePoint rollouts.
The company, Nuclino GmbH, sits in Munich and hosts inside the EU. The limits are deliberate and they matter against SharePoint specifically: there is no self-hosting, permissions are light for a large organisation that needs material compartmentalised, and there is no document management, no records retention and no intranet layer. This replaces the writing half and nothing else.
What Nuclino does better than SharePoint
- Fast enough that people actually write in it, which is the one measure SharePoint fails on daily
- No site, library or content type to choose before a page can exist
- Structure emerges from internal links rather than from an information architecture designed in advance
- German company with EU hosting and no US parent
- A free tier, and paid seats from roughly €6 a month
Where Nuclino is a step down from SharePoint
- No self-hosting at all, where SharePoint Server Subscription Edition still exists
- Permissions too light for an organisation that needs compartmentalised material
- No document management, retention or records handling of any kind
- Deliberately narrow, so it replaces the wiki half and leaves the rest where it is
Standout against SharePoint. It is the only tool here whose entire pitch is the absence of setup, which is exactly the tax SharePoint charges before the first word gets written.
- Which law reaches it. EU (Germany). SharePoint is run from the United States, so the CLOUD Act obliges the provider to hand over data on a valid order regardless of which country the servers are in.
- Where the data sits. Germany (EU).
- Source code. Closed source, as SharePoint is.
- Independently checked. GDPR.
Best for: Teams whose SharePoint work is a list somebody keeps reformatting
Zenkit is aimed at the SharePoint that is not really a document platform at all: a list of campaigns, a maintenance schedule, an onboarding tracker, kept in a library because that was where the permissions already worked. Its organising idea is that one set of records should be viewable as a board, a table, a calendar, a mind map or a hierarchy, so people look at the same data in the shape their job needs.
Against SharePoint that lands somewhere specific. SharePoint gives you a list and a view definition, and anybody who wanted to group, sort and filter comfortably exported to Excel — after which the spreadsheet became the real system and the list became a copy. Zenkit makes the table one of the views instead of one of the escapes.
It comes out of Karlsruhe, from Axonic Informationssysteme GmbH, hosted in Germany, with a free plan underneath the paid tiers and two siblings beside it: Hypernotes for documentation, Zenchat for conversation. It is not open source, cannot be self-hosted, and does not replace document management or an intranet — so treat it as the answer for one department rather than for the estate.
What Zenkit does better than SharePoint
- One dataset viewed as board, table, calendar, mind map or hierarchy without exporting to Excel first
- German company and German hosting, so no US corporation holds the records
- A free plan for small teams, where SharePoint requires a Microsoft 365 subscription per person
- Notes and chat in the same suite, so context stays beside the work
- Usable on the first afternoon, where a SharePoint list needs a site and a permissions decision first
Where Zenkit is a step down from SharePoint
- Not open source and not self-hostable, unlike the on-premises route SharePoint still offers
- No document management, retention or records handling
- Not an intranet, so the news and landing pages stay wherever they are
- Priced per user from €9, which for a large organisation costs more than a SharePoint seat already paid for
Standout against SharePoint. It is the only tool here that turns the Excel export into a supported view, which is where most SharePoint lists actually end up living.
- Which law reaches it. EU (Germany). SharePoint is run from the United States, so the CLOUD Act obliges the provider to hand over data on a valid order regardless of which country the servers are in.
- Where the data sits. Germany (EU).
- Source code. Closed source, as SharePoint is.
- Independently checked. GDPR, end-to-end encryption.
Best for: Legal, medical and advisory teams whose SharePoint holds material nobody outside should see
Stackfield takes the June 2025 problem and removes the premise. Microsoft could not guarantee that a US order would never reach French data because Microsoft can read that data; a provider that cannot read it has nothing useful to produce. Everything in Stackfield — messages, tasks, files, calls, boards and charts — is end-to-end encrypted with AES-256, and Stackfield GmbH in Munich holds no key to any of it.
That is a materially different claim from the EU Data Boundary, and the distinction is worth making carefully because both are described as protection. A boundary governs where data is processed and by whom, lawfully. Encryption governs whether the content is legible at all. For a law firm or a clinic, the second is the one the professional obligation actually asks about.
The costs are the ones encryption always brings, and they bite harder against SharePoint than against a chat tool. Search across document contents is constrained because the server cannot read them, integrations are limited for the same reason, and there is no records management, no retention policy engine and no intranet. Nor is the code open, so you learn how it works from a manual instead of a repository. From €4.99 per user per month.
What Stackfield does better than SharePoint
- AES-256 applied end to end, so the supplier holds ciphertext where Microsoft holds readable documents
- German company with German hosting and no US parent anywhere in the ownership chain
- Chat, tasks, files and calls in one product, where SharePoint depends on Teams beside it
- From €4.99 per user per month against a Microsoft 365 subscription that bundles far more than most people use
- A confidentiality claim you can put in front of a professional regulator rather than a residency diagram
Where Stackfield is a step down from SharePoint
- Encryption constrains full-text search, which is the thing large SharePoint estates depend on most
- No records management, retention policies or compliance holds
- Not open source and not self-hostable, so the architecture is taken on documentation
- A much smaller integration catalogue than the Microsoft 365 ecosystem
Standout against SharePoint. It is the only entry here whose reply to a disclosure order is ciphertext, not a policy describing how such orders get reviewed.
- Which law reaches it. EU (Germany). SharePoint is run from the United States, so the CLOUD Act obliges the provider to hand over data on a valid order regardless of which country the servers are in.
- Where the data sits. Your own infrastructure, or German hosting.
- Source code. Open source, where SharePoint is not: you can read what it does rather than take the description on trust.
- Independently checked. GDPR.
Best for: ISO-certified manufacturers and engineering firms running procedures out of document libraries
BlueSpice exists for the organisations whose SharePoint is holding controlled documents badly. A work instruction in a document library has a version number and a modified date, and that is not the same as evidence that the current revision was approved and that the named people acknowledged it. Approval workflows, document control and read confirmations are exactly the records an auditor asks for, and they are built in rather than assembled from a library and a flow.
Underneath it runs MediaWiki, the engine behind Wikipedia, so full-text search, revision history and a deep pool of extensions arrive already proven, and BlueSpice layers fine-grained rights and PDF output on top so a work instruction can carry a version number, an approver and a printout for the shop floor.
Hallo Welt! GmbH has been running it out of Regensburg since 2007, on your servers or on German hosting, with a GPLv3 edition at no cost and paid Pro and Farm editions above it.
It ranks last here because it is the narrowest answer, not the weakest one.
MediaWiki's interface and its wikitext syntax look their age, and that costs you adoption; running it yourself carries the operational duty July 2025 made vivid; and the quality-management side that justifies picking it at all sits behind the commercial editions. For an organisation with no compliance requirement it is overhead; for one with an audit next spring it is the only tool on this page that helps.
What BlueSpice does better than SharePoint
- Approval workflows before publication, where a SharePoint library records a version rather than an approval
- Read confirmations naming who acknowledged which revision, which document libraries cannot produce
- Self-hosted or German-hosted with a free GPLv3 edition, so no US corporation holds the procedures
- A MediaWiki foundation proven at a scale SharePoint search rarely matches on a large estate
- Granular permissions and PDF export for procedures that have to leave the screen
Where BlueSpice is a step down from SharePoint
- Dated interface and wikitext syntax, which is a harder sell than a SharePoint page
- Self-hosting brings the patching duty that the July 2025 SharePoint campaign made expensive
- Version control over approved documents belongs to the commercial editions, not the free GPLv3 one
- Pure overhead for an organisation with nothing to certify
Standout against SharePoint. It is the only tool here that produces the evidence an ISO auditor asks for, which a SharePoint document library has never been able to do.
What actually breaks when you switch
Permissions are the work, not the files. A decade of broken inheritance, per-item grants and sharing links issued to individuals is an accumulation rather than a design, and no target system will accept it as an import. Map who actually needs access before you move anything, and treat the existing structure as a record of past decisions rather than as a specification to reproduce.
The second trap is everything built out of lists. Registers, trackers, approval flows in Power Automate and the small applications someone made instead of raising a ticket are the part with no equivalent here. XWiki can rebuild them and Nextcloud cannot, but either way this is development work with a deadline, and it is usually discovered halfway through the file migration rather than before it.
And expect Teams to be the real incumbent. SharePoint gets opened because a tab in Teams points at it, so a replacement that lives at a different address competes with a habit rather than with a product. Decide in advance where people will click, and communicate that rather than the migration plan, because adoption is where these projects are lost.
If Microsoft keeps my data in the EU, what is left to solve?
The difference between where data sits and who can be ordered to produce it.
Microsoft built the EU Data Boundary in three phases — core customer data from January 2023, pseudonymised personal data from January 2024, and professional services data from February 2025 — and the result is genuinely more complete than what most vendors offer, including several in this directory.
It is not absolute, and Microsoft does not claim it is: the documentation records limited circumstances in which data still leaves the boundary, and professional services data is stored at rest inside it rather than processed inside it.
What it cannot alter is that Microsoft Corporation is American. That is not an inference drawn here; it is what the company told the French Senate in June 2025 when asked directly and under oath. The answer was that a valid US order reaches the company, that Microsoft contests requests it considers unjustified, and that no guarantee is available.
So the test is which question your obligation actually asks. A procurement rule about storage location is satisfied by SharePoint Online today. A risk assessment about foreign disclosure orders is not, and no configuration screen will change that. Organisations that confuse the two spend a year migrating for nothing, or stay put believing a problem is solved when it is not.
Can I still run SharePoint on my own servers?
Yes, which distinguishes SharePoint from several incumbents in this directory. SharePoint Server Subscription Edition has been generally available since November 2021 and is the current supported on-premises release. Nobody has taken the option away.
What has gone is the version most organisations were actually running. SharePoint Server 2016 and 2019 both reached end of support on 14 July 2026, and Microsoft has not announced a paid extended security update programme for either, so there is no supported way to stand still. Moving to Subscription Edition is a licensing change and a farm migration, typically measured in many months for a large estate.
And weigh July 2025 before treating on-premises as the cautious option. The ToolShell campaign compromised unpatched SharePoint servers without credentials, stole the machine keys that let attackers forge valid requests, and reached hundreds of organisations across government, telecommunications and software before the emergency patch landed. Running it yourself means owning that response.
Which of these can actually replace an intranet?
Nextcloud comes closest to the whole footprint, because an intranet in most organisations is mostly files with a front page attached. Files, calendar, contacts, Talk for chat and calls, and Nextcloud Office in one install gets you the daily surface, with an app marketplace covering the rest.
XWiki and BlueSpice replace the half of the intranet that is actually written material, and they do it far better than SharePoint pages do, because a wiki is designed for text that changes and a document library is designed for files that do not.
Nobody here reproduces the news-and-branding layer with SharePoint's polish, and nobody reproduces the Microsoft 365 integration, because that integration is the product. If the reason people open your intranet is that Teams put it there, expect adoption to be the hard part rather than the migration.
What happens to the permissions model?
It does not travel, and this is where SharePoint migrations genuinely go wrong. Years of broken inheritance, per-item permissions, sharing links issued to individuals and groups whose purpose nobody remembers do not map onto another system, because they are not a design — they are an accumulation.
XWiki and BlueSpice both offer granular permissions with LDAP and SSO, so the target can express what you need. That is different from receiving what you have. The realistic approach is to model the permissions you intend to have, apply them to the migrated content, and treat the existing ones as documentation of past decisions rather than as a specification.
Budget for the discovery rather than the import. Working out who currently has access to what is usually the longest task in the project, and it is the one nobody puts on the plan.
Which one to pick
If the requirement is that no US corporation can be ordered to produce your documents, Nextcloud is the complete answer and a European managed host is the sensible way to run it. That removes the party Microsoft's own lawyer said he could not shield, rather than moving the data inside a boundary drawn by the same company.
If the content is confidential in a professional sense — client files, patient records, deal documents — Stackfield is the sharper answer, because end-to-end encryption makes the disclosure question moot instead of arguing it. Accept the search limitations knowingly; they are the price and they are real.
If what you are replacing is written knowledge rather than files, pick by organisation. XWiki for permissions, structure and the lists nobody planned; BlueSpice if an auditor will ask who read which revision; Nuclino if the true problem is that nothing gets written down at all.
And if your estate runs on content types, retention labels and forty Power Automate flows, no tool on this page replaces it, and the honest advice is to move to SharePoint Server Subscription Edition or stay on SharePoint Online with the data boundary switched on — knowing exactly what that does and does not settle.
Frequently Asked Questions
Nextcloud if you are replacing the whole footprint — files, sharing, calendar, calls and documents on infrastructure you choose. XWiki if the part that matters is structured written knowledge with real permissions. BlueSpice if you are a regulated manufacturer and an auditor asks who read which revision. Stackfield if the content is confidential enough that the provider should not be able to read it. Nuclino if the honest problem is that nobody writes anything down.
Largely, yes. Microsoft completed the EU Data Boundary on 26 February 2025 across three phases, covering core customer data, pseudonymised personal data and, in the final phase, the professional services data created when an EU customer raises a support case.
Two details from Microsoft's own documentation belong in any procurement answer: customer data and pseudonymised logs are stored and processed within the boundary while professional services data is stored at rest within it, and the commitment is expressed as subject to limited circumstances in which data still transfers outside.
For a requirement written in terms of storage location, SharePoint Online essentially meets it. The open question is jurisdiction over the company holding it, which is a different requirement.
Microsoft Corporation is a US company, so yes, and the company has said so itself. Asked by the French Senate in June 2025 whether he could guarantee under oath that French citizens' data would never be passed to US authorities without French approval, Microsoft France's director of legal affairs answered that he could not. Microsoft states that it reviews and challenges requests it regards as unjustified, which is a mitigation rather than a guarantee.
SharePoint Server 2016 and SharePoint Server 2019 both reached end of support on 14 July 2026 and receive no further security updates. Microsoft has not announced a paid extended security update programme for either, unlike Windows Server and SQL Server. The supported on-premises release is SharePoint Server Subscription Edition, generally available since November 2021.
Not by default, and July 2025 is the evidence. The ToolShell campaign exploited CVE-2025-53770 in on-premises SharePoint, an unauthenticated deserialisation flaw scored 9.8, extracting ASP.NET machine keys to forge requests the server accepted as valid. Check Point counted over 4,600 compromise attempts against more than 300 organisations by 24 July, before and after Microsoft's emergency patch. On-premises means you own the patching window, not that the window is smaller.
The files, yes, and there are supported routes for bulk transfer. What does not carry across is everything SharePoint wrapped around them: metadata columns, content types, retention labels, version history in full, and the permission structure. Plan to move current documents with a deliberate folder structure rather than replicate a site collection, because replicating it faithfully reproduces the problem you were leaving.
Nothing on this page does it one for one, and that is worth knowing before you start. XWiki comes closest: it keeps typed fields inside the page itself, and its application builder assembles sets of those pages into working tools — a register of suppliers, a log of equipment, a record of decisions. It is a rebuild rather than a migration, and if your SharePoint runs on dozens of flows, that rebuild is the project.
Only Stackfield does, and nothing else on this page comes close. Everything in the workspace is end-to-end encrypted with AES-256, so Stackfield GmbH in Munich cannot read the files, tasks or messages. That is a different guarantee from the EU Data Boundary, which controls where data sits and who processes it lawfully rather than making the content unreadable. The cost is that search across content and integrations are both more constrained.
The files are weeks; the structure is the project. A department moving a few libraries and a handful of pages can be finished in a month. An organisation with a decade of site collections, broken permission inheritance, content types and Power Automate flows should plan in quarters and treat it as an information-architecture exercise with a migration attached, because most of what is being moved is decisions rather than documents.
