European Alternatives to SolarWinds
Looking for a European alternative to SolarWinds? Its EULA is a contract with SolarWinds Worldwide, LLC of Austin, Texas, governed by Texas and United States law with the state and federal courts of Texas, and its privacy policy says personal data can be processed in any country where SolarWinds has facilities.
Eleven European tools cover the job: open-source and commercial infrastructure and network monitors (openITCOCKPIT, NetXMS, Pandora FMS, Checkmk, Zabbix, Icinga, Paessler PRTG, Centreon, XorMon), plus ITRS and Elastic for larger estates, from companies in Germany, Latvia, Spain, France, the United Kingdom, the Czech Republic and the Netherlands.
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
- SolarWinds' EULA is a contract with SolarWinds Worldwide, LLC of Austin, Texas, under Texas and United States law, with Texas courts.
- openITCOCKPIT (Fulda), NetXMS (Riga) and Pandora FMS (Spain) are the three challenger options: each has a free edition or free software and public support or licence prices.
- Checkmk, Zabbix and Icinga are the established open-source-based monitors, with Zabbix and Icinga free for unlimited hosts and Checkmk publishing euro prices from €190 a month.
- NetXMS is the one that stresses network topology: it discovers layer 2 and layer 3 topology and has 45+ device drivers, with support from €3,800 a year.
- None of the eleven is documented as replacing every SolarWinds module; flow analysis, configuration management and IP address management usually mean a second tool.
Why people leave SolarWinds
SolarWinds is best known for the Orion platform, a self-hosted suite of network and IT monitoring modules. Network Performance Monitor discovers SNMP devices, maps their relationships, tracks response time, packet loss, bandwidth and hardware health, and adds NetPath, which shows hop-by-hop latency across on-premises and cloud paths. Add-on modules cover traffic flows (NetFlow), configuration management (NCM), server and application monitoring (SAM) and IP address management (IPAM). Its product page offers a 30-day trial and sells by quote.
The contract is where the European question sits. The EULA, last updated 5 September 2025, names SolarWinds Worldwide, LLC of Austin, Texas, as the party, with the laws of Texas and of the United States and the state and federal courts of Texas. The separate website terms send disputes to confidential binding arbitration in Austin under ICC rules, and say they were last updated in 2012.
The privacy policy, updated 9 September 2026, names SolarWinds Corporation US, SolarWinds Worldwide, LLC and SolarWinds Software Europe DAC among its controllers, and says personal data may be stored and processed in any country where SolarWinds has facilities, using adequacy decisions or standard contractual clauses for transfers. So a European affiliate exists. Whether you contract with it is not stated in the EULA, so the order form is the document to check.
- The EULA names a Texas company and Texas law Unless your order form says otherwise, the license agreement is with SolarWinds Worldwide, LLC, governed by Texas and United States law with Texas courts as the forum. A European supplier gives you a counterparty and a court in Europe, in the German, Latvian, Spanish, French, Czech, British or Dutch jurisdictions of the tools below. For most monitoring buyers this is a procurement question, not a technical one.
- Data can be processed anywhere SolarWinds operates The privacy policy allows processing in any country or region where SolarWinds has facilities or service providers. That is lawful with the safeguards it lists, but it is a transfer you have to document. Orion is self-hosted, which limits what leaves your network; the SaaS observability products and support tickets are a different matter. The tools below that you run yourself keep monitoring data on your own servers.
- Price is by quote, with modules on top SolarWinds publishes no price on its NPM page, only a 30-day trial and a quote route, and full coverage means several modules (flows, configuration, applications, IP space). Most tools here publish some price, or are free: Zabbix, NetXMS, Icinga and openITCOCKPIT have no licence fee, Pandora FMS has a free edition for 50 agents, and Checkmk and Centreon list euro prices.
- Open source is a real option in this category Network and infrastructure monitoring has mature open-source projects with European companies behind them. That lets you inspect the code, run it on your own hardware and buy support only when you need it. SolarWinds is a commercial product, so that route does not exist with it.
What you have to replace, not just match
List what you actually use in Orion before you compare: SNMP device polling and maps, flow analysis, configuration backup and change tracking, server and application checks, IP address management, or the observability modules. The European tools here are strongest on device and server monitoring with alerting. Flow analysis, configuration management and IPAM are separate jobs, and none of these eleven is documented on its pages as covering all of them.
Run the new tool beside Orion for a month on a representative slice of the network. Compare alerts, not dashboards: which tool noticed first, which gave fewer false alarms, and whether your SNMP devices were discovered correctly. Rebuild only the alert rules people actually act on, since Orion alerts and maps do not import into any of these.

How each alternative compares to SolarWinds
openITCOCKPIT
a free German monitoring suite with public Enterprise prices
Best for: Teams that want an open-source monitor on Naemon with an upgrade path to support and integrations
openITCOCKPIT is developed by it-novum GmbH of Edelzeller Strasse 44, Fulda, registered at the Amtsgericht Fulda under HRB 1934, and its imprint says it is part of Allgeier SE.
Its editions page describes a free, open-source Community edition with no limit on hosts and services, built on Naemon, and an Enterprise edition that adds integrations with Checkmk, Prometheus and ITSM systems and distributed monitoring. Enterprise subscriptions run from €1,000 a year for 1,000 services to €9,999 a year for 30,000, and Premium support is €14,999 a year.
It is a host and service monitor with a web interface, not a network performance suite with flow analysis. Its governing law for subscriptions could not be read.
What openITCOCKPIT does better than SolarWinds
- Free Community edition with no host limit
- Enterprise prices in euro on the page
- German company with a commercial-register number in its imprint
- Integrations with Checkmk, Prometheus and ITSM tools in Enterprise
Where openITCOCKPIT is a step down from SolarWinds
- No flow analysis, configuration management or IP management documented
- Smaller user base than Zabbix or Checkmk
- Subscription terms could not be read
- Enterprise service tiers are capped by service count
Standout against SolarWinds. A free edition plus a price list from €1,000 a year, from a company that names its register entry.
NetXMS
open-source network monitoring with topology discovery, from Riga
Best for: Network teams that want automatic L2/L3 topology and SNMP monitoring, with optional paid support
NetXMS is developed by Raden Solutions SIA of Antonijas str. 24-12A, Riga, Latvia, according to its own company page. The software is GPLv2 with no node limit on Linux, and the version on its site is 6.2.5, released 14 September 2026.
It lists layer 2 and layer 3 topology discovery through ARP, routing tables, STP, LLDP and CDP, device drivers for more than 45 vendors including Cisco, Juniper, Huawei and MikroTik, SNMP and agent-based monitoring, and event processing with scripting. Support is priced at €3,800 a year (Basic), €6,500 (Standard) or €12,500 (Premium), and Enterprise is by quote.
It is the closest to the Orion network focus among the free options, but it is a lesser-known product with a smaller community, and its terms and governing law could not be read.
What NetXMS does better than SolarWinds
- Topology discovery with a free, GPLv2 core
- Support prices published in euro, with a non-profit discount
- Device drivers aimed at network vendors
- Latvian company named on the site
Where NetXMS is a step down from SolarWinds
- Smaller community and fewer ready-made templates than Zabbix or Checkmk
- Support starts at €3,800 a year, which is high for small teams
- No flow analysis or configuration management documented on the pages read
- Governing law of a support contract could not be verified
Standout against SolarWinds. Automatic network topology from a free GPLv2 core, with support priced in public.
Pandora FMS
a Spanish monitor with a free 50-agent edition and an NMS edition
Best for: Teams that want one vendor for monitoring, with optional ITSM and remote management editions
Pandora FMS is operated by Pandora FMS S.L.U. of José Echegaray 8, Las Rozas de Madrid, with tax ID ES-B84491109, according to its privacy policy, which cites Spanish law and GDPR. The site markets itself as made in Spain and has been developed since 2005.
Its pricing page lists a free version for up to 50 agents with community support, ONE from €2,447 a year, a Monitoring as a Service offer from €783 a month, an NMS edition from €1,590 a year, and an MSP option from €0.51 per agent per month. Licences are per device, with unlimited monitors per agent, and over 500 plugins are listed.
The site also lists network topology mapping and equipment scanning. Several editions exist, so check which one holds the features you need.
What Pandora FMS does better than SolarWinds
- Free edition for 50 agents
- A dedicated network monitoring (NMS) edition
- Device-based licences, not per sensor
- Prices in euro on the page
Where Pandora FMS is a step down from SolarWinds
- Many editions to choose between
- Free edition has community support only
- Governing law of customer contracts could not be read
- Its site blocks automated requests, which makes checking harder
Standout against SolarWinds. A free tier, an NMS edition and per-device licensing from a Spanish company with a tax ID in its privacy policy.
- Which law reaches it. EU (Germany). SolarWinds 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. Self-hosted, or Checkmk Cloud.
- Source code. Open source, where SolarWinds is not: you can read what it does rather than take the description on trust.
Best for: IT teams that want infrastructure and network monitoring self-hosted or as a managed service
Checkmk is provided by Checkmk GmbH of Kellerstrasse 27, Munich, registered at the Munich District Court under HRB 165902.
Its pricing page lists a free Community edition for small infrastructures (about 100 hosts), Pro from €190 a month and Ultimate from €275 a month on annual billing, and a managed Cloud edition at €240 a month. Pricing follows services, such as a file system or a switch port, with about 30 services per host on average. Ultimate adds full-stack observability and cloud integrations.
Checkmk's terms were not reopened for this page, so which entity signs your order, and which law applies, is something to confirm on the quote.
What Checkmk does better than SolarWinds
- Free Community edition and euro prices on the page
- Large library of checks for network gear and servers
- Managed Cloud edition if you do not want to run it yourself
- German company with a register number
Where Checkmk is a step down from SolarWinds
- Service-based pricing is harder to estimate than a host count
- Community edition is aimed at about 100 hosts
- No flow analysis or IP management documented
- Contracting entity for paid editions not verified here
Standout against SolarWinds. Prices from €190 a month on the page, with a clear service-based unit.
- Which law reaches it. EU (Latvia). SolarWinds 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. Self-hosted — wherever you run it.
- Source code. Open source, where SolarWinds is not: you can read what it does rather than take the description on trust.
Best for: Large estates where per-device pricing is the problem
Zabbix's privacy policy names SIA Zabbix, registered in Latvia (number 40003738045) at Gustava Zemgala gatve 74, Riga, as the controller.
Its subscriptions page lists Silver at €245 a month and Gold from €660 a month, billed annually, with Platinum, Enterprise and Global on request, and says there are unlimited hosts, devices, users, metrics and alerts. A subscription buys support and maintenance, not the software.
Its subscription terms were not read for this page, so the contracting entity and governing law of a paid subscription are unverified.
What Zabbix does better than SolarWinds
- No licence fee and no host or device limits
- Open source, so you can host and inspect it
- Support prices in euro on the page
- Large community and many templates for network devices
Where Zabbix is a step down from SolarWinds
- Subscription terms and governing law not verified
- You run and tune the server and database yourself
- Flow analysis and configuration management are not part of it
- Steeper setup than a guided, commercial wizard
Standout against SolarWinds. Cost does not grow with the number of devices; you pay for support.
- Which law reaches it. EU (Germany). SolarWinds 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. Self-hosted — wherever you run it.
- Source code. Open source, where SolarWinds is not: you can read what it does rather than take the description on trust.
Best for: Teams that treat monitoring as code and want clustering and a Git-based workflow
Icinga is provided by Icinga GmbH of Deutschherrnstr. 15-19, Nuremberg, registered under HRB 35189.
Its pricing page describes a free and open-source edition with unlimited hosts and services, clustering and automation, plus paid options: a Repository subscription (around €5,000 a year, with a 60-day trial), a Module subscription (around €2,000 a year) and a Support subscription starting at €15,000 a year. It states that prices vary by region, so this page gives no firm amount.
It is configured through files and an API, more than through a wizard, which suits teams who automate.
What Icinga does better than SolarWinds
- Unlimited hosts and services free
- Clustering and API-driven automation
- German company with a register number
- Integrations with Grafana and Prometheus
Where Icinga is a step down from SolarWinds
- Less guided than a commercial network suite
- Support starts at a high price point
- Prices vary by region
- No flow or configuration management
Standout against SolarWinds. A genuinely free edition that is not limited by host count, with paid modules only if you need them.
- Which law reaches it. EU (Germany). SolarWinds 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. Self-hosted, or PRTG Hosted Monitor (managed cloud).
- Source code. Closed source, as SolarWinds is.
Best for: Network admins who want a guided Windows-based tool with a long trial
PRTG is made by Paessler GmbH of Thurn-und-Taxis-Str. 14, Nuremberg, registered at the Nuremberg District Court under HRB 43342.
Its pricing page offers a 30-day trial with unrestricted sensors and a Freeware edition for up to 100 sensors, about 10 devices, plus subscription licences by sensor count. The amounts on the page are in dollars, so no price is quoted here.
PRTG is the closest in feel to Orion: a single server product with auto-discovery and maps. Sensor-based licensing means large networks can cost more than a per-host model.
What Paessler PRTG does better than SolarWinds
- Freeware to 100 sensors and a full 30-day trial
- Easy first setup and a familiar guided interface
- Sensor limits are clearly stated by tier
- German company with a register number
Where Paessler PRTG is a step down from SolarWinds
- Sensor-based pricing can grow quickly
- Prices shown in dollars
- Different licence versions cannot be mixed on one server
- No flow or configuration modules like Orion's
Standout against SolarWinds. The most Orion-like feel on this list, with a free tier of 100 sensors.
- Which law reaches it. EU (France). SolarWinds 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.
- Source code. Open source, where SolarWinds is not: you can read what it does rather than take the description on trust.
Best for: Mid-size teams that want per-host tiers on a clear price list
Centreon is published by CENTREON SAS, registered in Paris under RCS 483 494 589, with share capital of €500,000, at 28/34 rue du Château des Rentiers.
Its pricing page is titled Free up to 100 Hosts. It lists the IT edition at €425 a month for 125 hosts on SaaS and €283 a month for 125 hosts self-hosted, and the Pro SaaS edition at €1,125 a month for 250 hosts, all billed annually, with per-host cost tapering beyond that.
It is an infrastructure and service monitor. It does not document flow analysis.
What Centreon does better than SolarWinds
- Free tier to 100 hosts
- Prices for both SaaS and self-hosted
- French company with a full registration in the legal notice
- Per-host pricing that is easy to forecast
Where Centreon is a step down from SolarWinds
- Narrower than the whole Orion suite
- Larger tiers are on request
- Smaller community than Zabbix
- No flow or IPAM modules documented
Standout against SolarWinds. Both SaaS and self-hosted prices are on the page, plus a free tier.
ITRS
London group behind Opsview, sold by quote
Best for: Large or regulated organisations that buy through a vendor relationship
ITRS Group Limited, 15 Bonhill Street, London, is the controller named in its privacy notice, updated 5 November 2025. The United Kingdom is outside the EU but inside the set this directory accepts.
Its infrastructure page describes Opsview as infrastructure and network monitoring with business service monitoring for hybrid IT, alongside Geneos and ITRS Monitoring for financial services and regulated industries. No prices are published; the page offers a demo request.
The product page for Opsview alone returned a 404, so the Opsview details come from the overview page only.
What ITRS does better than SolarWinds
- Vendor support for large and regulated estates
- Business service monitoring in Opsview
- UK company named in its privacy notice
- Geneos for application monitoring
Where ITRS is a step down from SolarWinds
- No published price and no trial documented
- Aimed at large organisations, heavier than a small team needs
- Ownership of the group not verified
- No free edition
Standout against SolarWinds. A single vendor for infrastructure monitoring and enterprise application monitoring, sold by quote.
XorMon
a Czech monitor strong on storage and virtualization
Best for: Teams that monitor storage arrays, hypervisors and databases next to servers and network
XorMon is from Xorux, whose contact page lists Janovicka 271, 251 01 Babice, Czech Republic, registration number 021 32 907 and VAT number CZ02132907. Its legal form was not found, and its privacy policy names no formal entity.
The site describes an open-source core with optional enterprise support, monitoring across servers, storage, virtualization, databases, containers and network, and topology mapping. It offers a free demo without signup, but publishes no prices.
Treat it as a good fit where SolarWinds' storage and virtualization monitoring matters most, and ask for the contract entity before you commit.
What XorMon does better than SolarWinds
- Wide support for storage and virtualization platforms
- Open-source core and a no-signup demo
- Czech registration and VAT number on the contact page
- AI assistant for performance questions
Where XorMon is a step down from SolarWinds
- No prices published
- Legal form and terms not found
- Less focused on network device monitoring
- Small public footprint compared with Zabbix or Checkmk
Standout against SolarWinds. Storage, virtualization and server monitoring in one tool, with a demo you can open without an account.
Elastic Observability
logs, infrastructure and APM on one platform, for the observability side of SolarWinds
- Which law reaches it. EU (Netherlands). SolarWinds 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. Self-hosted, or Elastic Cloud in EU regions.
- Source code. Open source, where SolarWinds is not: you can read what it does rather than take the description on trust.
- Independently checked. GDPR.
Best for: Teams that use SolarWinds' newer observability products and want logs and traces on a search platform
Elastic N.V. is the controller in its privacy statement, at Keizersgracht 281, Amsterdam, as of 7 September 2026. The statement says Elastic takes part in the Data Privacy Framework and uses standard contractual clauses for transfers.
Elastic Observability covers logs, infrastructure metrics, APM and tracing, and user experience monitoring on the Elastic search platform, with a free trial. It is not a SNMP network manager in the Orion sense and needs more build effort for device polling.
The contracting entity on paid cloud agreements was not verified for this page, and no price was read.
What Elastic Observability does better than SolarWinds
- Logs, metrics and traces together on one platform
- Trial available
- Dutch parent named in its privacy statement
- Search power over large log volumes
Where Elastic Observability is a step down from SolarWinds
- Not an SNMP-first network monitor
- Paid contract entity not verified
- Needs more setup effort than a dedicated monitor
- No price read for this page
Standout against SolarWinds. The only option here that treats logs, traces and infrastructure as one search problem.
What actually breaks when you switch
The hardest part of leaving Orion is rebuilding discovery, maps and alert rules. In Zabbix, Icinga, Checkmk or NetXMS you define templates and checks, and discovery must be tuned for your device mix. Budget weeks, not days, for a network of any size.
Run both tools in parallel before cancelling. SolarWinds sells by quote with separate modules, so check your renewal date and notice period before planning a migration, and keep the old server available for historical data.
Self-hosted tools move cost from licence to operations. A free edition of Zabbix, NetXMS or openITCOCKPIT still needs a server, storage sizing, upgrades and someone on call. Count that next to the SolarWinds invoice.
Is there a European tool that replaces all of SolarWinds?
Not on the evidence of their own pages. SolarWinds sells an Orion suite of separate modules for network performance, flows, configuration, applications and IP space. The European tools here are broad monitors for devices, servers and services, with alerting and maps, and each is stronger in some of those areas than others.
Pandora FMS lists a separate NMS edition for network monitoring and ITSM and RMM editions alongside, and Checkmk, Zabbix and Icinga are platforms you extend with plugins and integrations. Plan to combine tools for flows and configuration rather than expect one replacement.
Which of these are free to start?
openITCOCKPIT has a free Community edition, NetXMS is GPLv2 software with no node limit on Linux, Zabbix has no licence fee, Icinga's free edition covers unlimited hosts and services, Checkmk has a free Community edition for about 100 hosts, Centreon is free up to 100 hosts, PRTG has a Freeware edition up to 100 sensors, and Pandora FMS has a free edition for up to 50 agents with community support.
XorMon offers a free online demo and Elastic offers a trial. A free edition is not a free operation: you size, patch and run it yourself.
Which of these work well for network devices rather than servers?
NetXMS describes SNMP monitoring, device drivers for vendors such as Cisco, Juniper, Huawei and MikroTik, and layer 2 and layer 3 topology discovery. Pandora FMS lists network topology mapping and equipment scanning. PRTG is sensor-based and covers network and server monitoring. Checkmk, Zabbix, Icinga and Centreon all poll network gear through SNMP and plugins.
Which is best depends on your device mix. Test discovery on your own switches and firewalls during the trial, because vendor MIB coverage differs between tools.
Can I keep monitoring data inside my own network?
Yes, with the self-hosted options. openITCOCKPIT, NetXMS, Pandora FMS (on-premise), Checkmk, Zabbix, Icinga, PRTG, Centreon (self-hosted), XorMon and ITRS Opsview can run on your own servers, so the data stays where you put it. Hosted offers such as Checkmk Cloud, Centreon SaaS, Pandora FMS MaaS and Elastic Cloud put it with the supplier, so check their hosting regions and sub-processors before you sign.
Which one to pick
If you want a free monitor with a public upgrade path, start with openITCOCKPIT, or NetXMS if network topology and SNMP devices are the main job. Pandora FMS is worth trying if you want a dedicated network edition and a Spanish vendor with a free 50-agent tier.
If you want the biggest ecosystems, choose Zabbix (no per-device licence), Checkmk (published prices from €190 a month) or Icinga (free for unlimited hosts, configured as code). PRTG is the nearest in feel to Orion and has a free 100-sensor edition, and Centreon is the French option with a clear price list.
Be realistic about the gap. None of the eleven is documented as covering flow analysis, configuration management and IP address management in one product, so a move often means two tools. Switch if you want a European contracting party and the option to host monitoring data yourself, and ask SolarWinds which entity is on your order form if you stay.
Frequently Asked Questions
It depends on the job. For a free monitor with public enterprise prices, openITCOCKPIT is a strong first look. For network topology and SNMP devices, look at NetXMS and Pandora FMS. For the widest community and plugin ecosystem, Checkmk, Zabbix and Icinga. For larger estates with a quote-based sale, ITRS. No single tool is best on every criterion.
Its EULA names SolarWinds Worldwide, LLC of 7171 Southwest Parkway, Austin, Texas, as the contracting party, under Texas and United States law. Its privacy policy also names SolarWinds Software Europe DAC among its controllers, so a European affiliate exists, but the EULA does not say European customers contract with it.
Its Network Performance Monitor page shows no price, only a 30-day free trial and a quote through its online portal. Orion modules are licensed separately, so the total depends on which ones you add.
openITCOCKPIT Enterprise runs from €1,000 a year (1,000 services) to €9,999 a year (30,000 services). NetXMS support is €3,800, €6,500 or €12,500 a year. Pandora FMS lists ONE from €2,447 a year and NMS from €1,590 a year. Checkmk Pro starts at €190 a month and Ultimate at €275, billed annually. Zabbix support is €245 a month for Silver and from €660 for Gold. Centreon lists €425 a month for 125 hosts on SaaS and €283 on self-hosted, billed annually.
NetXMS is released under GPLv2, openITCOCKPIT's Community edition is open source, Icinga describes its free edition as free and open source, Zabbix is open source with no licence fee, Checkmk's Community edition is described as free and open source, Pandora FMS lists an open-source version, and XorMon describes an open-source core. Licences differ between editions, so read the one for the edition you will run.
It-novum GmbH, Edelzeller Strasse 44, Fulda, registered at the Amtsgericht Fulda as HRB 1934, and part of Allgeier SE according to its imprint. The Enterprise edition adds integrations with Checkmk and Prometheus and ITSM tools, plus distributed monitoring.
Raden Solutions SIA of Antonijas str. 24-12A, Riga, Latvia, which developed the software and sells support, services and training. Its pricing page also lists courses from €800 per person.
Its privacy policy names Pandora FMS S.L.U. of José Echegaray 8, Las Rozas de Madrid, with tax ID ES-B84491109, as the data controller. Its governing law for customer contracts could not be read, so ask for the contract before you buy.
Elastic N.V. is the controller named in its privacy statement, with its address at Keizersgracht 281, Amsterdam, as of 7 September 2026. It also takes part in the Data Privacy Framework and uses standard contractual clauses. The entity on paid cloud agreements was not verified for this page.
They do not convert. Orion maps, alert definitions and dashboards have no import in these tools, so rebuild the ones in daily use. Export your node list and the alert conditions people actually respond to, and keep the old Orion server available read-only for as long as you need its history.
