European Bug Bounty Platforms

A bug bounty platform sits between your systems and outside researchers, so every vulnerability report, proof of concept and scope document passes through it before you have fixed anything. These European platforms and testing services cover crowdsourced bounties, vulnerability disclosure programs and pentest-as-a-service, run by companies contracting from France, Belgium, the Netherlands, Switzerland and elsewhere in Europe.

How we rank these tools — 4-step process
  1. 1
    European ownership, verified

    The company is headquartered and incorporated in the EU, EEA, the UK, Switzerland or Israel, and processes customer data in Europe or Israel. A US parent company disqualifies a tool from this page regardless of where its servers are.

  2. 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. 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. 4
    Position on this page

    Placement on this page can be paid, and that can affect the order tools appear in. It never buys a listing: 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 the order in which tools appear; it never affects whether a tool is listed. Editorial policy

Key takeaways

  • YesWeHack, a Paris company, ranks first because it is the only platform in this list that states EU-only hosting in a SecNumCloud-qualified private cloud and also has its own staff triage incoming reports.
  • Intigriti NV in Antwerp and Yogosha in Paris cover the same crowdsourced ground with different philosophies: Intigriti draws on a community the vendor puts above 150,000 researchers, while Yogosha admits about one applicant in ten into a vetted pool.
  • Only three vendors here publish money figures: Detectify (a free tier up to EUR 15,000 a year), Pentest-Tools.com (from $96 a month) and Securitum (EUR 640 to 890 per day), while YesWeHack, Intigriti, Yogosha, Zerocopter, SignalFisher, Ethiack and Vaadata quote on request.
  • Ethiack, Securitum and Vaadata sell testing, not a researcher crowd, so they replace a yearly pentest rather than a HackerOne bounty.
  • Patchstack of Estonia is the single specialist, covering vulnerabilities in WordPress and open-source software only, while SignalFisher of Lucerne is the one Swiss entry and sits outside the EU.

European bug bounty platforms are services, run by companies contracting from inside the EU, the UK or Switzerland, through which a company invites outside security researchers to find and report flaws in its systems and pays for valid findings, and the European part matters because every report is a description of an unpatched weakness that then sits in the vendor's hands under a legal system you can name.

Every European bug bounty platform reviewed

#1 YesWeHack

Paris, France Founded 2015 Pricing on request; the vendor site publishes no price list Demo on request

Best for: Security teams that want a managed bounty with in-house triage and EU-only hosting

  • Operating company. Yes We Hack S.A.S.
  • Jurisdiction. EU (France)
  • Where the data sits. EU only, in a SecNumCloud-qualified private cloud (per vendor trust page)
  • Source code. Closed source
  • Replaces. HackerOne, Bugcrowd

YesWeHack runs its platform from Paris and contracts through Yes We Hack S.A.S., founded in 2015, so a customer signs with a French simplified joint stock company. The vendor says its community has more than 160,000 ethical hackers and that incoming reports are triaged by its own employees, who remove duplicates, reproduce the proof of concept and set severity. A customer success team helps set up the first programme: private or public, budget, reward grid and later scope changes.

The trust page states hosting in a SecNumCloud-qualified private cloud with European providers only, and ISO 27001 and ISO 27017 certificates are listed. Customers can enforce two-factor login, connect SAML 2.0 single sign-on and route hunter traffic through a fixed-IP VPN. Prices are not published, the managed model is heavier than a small team needs, and the vendor also has offices in Singapore, so confirm which entity signs the order form.

What YesWeHack does well

  • Triage performed in-house, not outsourced
  • EU-only hosting in a SecNumCloud-qualified cloud
  • ISO 27001 and ISO 27017 certified
  • Bounty, VDP and agentic pentest on one platform
  • SSO, 2FA and fixed-IP hunter VPN

Where YesWeHack falls short

  • No published prices
  • Managed model is heavy for very small programs
  • Broad module list needs scoping in the contract
  • Offices also in Singapore, so check which entity signs the order form

Standout feature. It is the only platform in this list that names EU-only hosting in a SecNumCloud-qualified environment and pairs it with employee-run triage.

#2 Intigriti

Antwerp, Belgium Founded 2016 Plans named Core, Premium and Enterprise; prices on request Demo on request

Best for: Companies that want a bounty and a pentest-as-a-service option from one Belgian vendor

  • Operating company. Intigriti NV
  • Jurisdiction. EU (Belgium)
  • Where the data sits. Not stated on the pages checked; stored data is encrypted at application level
  • Source code. Closed source
  • Replaces. HackerOne, Bugcrowd

Intigriti is the Antwerp platform operated by Intigriti NV, which its company information page names at Klokstraat 16, and the about page says it was founded in 2016. The vendor reports more than 100 employees across Belgium, the UK, the US, the Netherlands and South Africa, and a EUR 21 million Series B round in 2022. An in-house team vets incoming reports, and the platform pages mention access to more than 150,000 independent researchers.

Beyond the bounty, Intigriti sells managed vulnerability disclosure and pentest as a service in Focused, Comprehensive and Certified types, plus live hacking events and programmes scoped around AI features. Plans are named Core, Premium and Enterprise, with prices on request. The pages checked do not name a hosting location, though a published post explains application-level encryption of stored data, and the product pages mark the pentest offer and CrowdRecon as beta.

What Intigriti does well

  • Belgian entity (Intigriti NV) as operator
  • In-house triage of incoming reports
  • Bounty, VDP and PTaaS in one place
  • Application-level encryption of stored data
  • AI security and safety programs

Where Intigriti falls short

  • No prices published
  • Hosting location not stated on pages checked
  • PTaaS offer is marked beta on the product page
  • Offices in the US and UK besides Belgium

Standout feature. Its Certified pentest type targets regulated buyers inside the same contract as the bounty, which no other crowd platform here offers.

#3 Yogosha

Paris, France Founded 2015 Pricing on request; PtaaS is described as fixed cost, bounty as pay per valid vulnerability Demo on request

Best for: Teams that want a closed, vetted researcher pool for pentests and private bounties

  • Operating company. Yogosha (S.A.S. Yogosha by Creative, per website terms)
  • Jurisdiction. EU (France)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. HackerOne, Bugcrowd

Yogosha is a Paris offensive-security platform founded in 2015, whose website terms name S.A.S. Yogosha by Creative. Its research pool is called the Strike Force, and according to the vendor only 10 percent of applicants are accepted after a technical and written test, with ID checks and an NDA for members. The site cites 1,100 or more researchers for pentests and more than 800 in the private bounty community.

Pricing logic differs by product: pentest as a service is described as a fixed cost for a small team on a defined asset, while bounty pays per valid vulnerability. Special operations include red teaming, hardware pentesting and social engineering, and the home page promotes audits of LLM systems. Prices and hosting location are not stated on the pages checked, and the pool is deliberately smaller than an open crowd.

What Yogosha does well

  • Researchers pass a test and an ID check
  • Fixed-cost PtaaS next to pay-per-bug bounty
  • Special operations including hardware and red team
  • Documented reports with remediation guidance
  • Paris-based contracting entity

Where Yogosha falls short

  • No published prices
  • Hosting location not stated on pages checked
  • Smaller pool than open crowds
  • Public program reach is limited by design

Standout feature. Joining its researcher pool takes a test, an identity check and an NDA, and the vendor says nine in ten applicants are turned away.

#4 Detectify

Stockholm, Sweden Founded 2013 Starter free (up to 5 users, 100 assets) / Standard €2,500 / Professional €5,000 / Enterprise €15,000 per year Demo on request

Best for: Security teams that want continuous external scanning of their web assets and a price list they can budget from

  • Operating company. Detectify AB
  • Jurisdiction. EU (Sweden)
  • Source code. Closed source
  • Replaces. Tenable, Qualys, Invicti

Detectify is a Stockholm company, Detectify AB, founded in 2013, that combines external attack surface management with dynamic application security testing. It maps what an organisation exposes to the internet and then tests each asset, drawing payloads partly from its own research and partly from Crowdsource, a network of more than 400 ethical hackers. Coverage reaches REST and GraphQL APIs from the Standard tier.

Prices are public: a free Starter tier for five users and 100 assets, Standard at EUR 2,500, Professional at EUR 5,000 and Enterprise at EUR 15,000 per year. Standard caps at 750 assets and 10 users, and CI/CD integration starts at Professional. It is a scanner, not a WAF or CDN, so it reports exposure and blocks nothing, and no human reads your application the way a bounty researcher does.

What Detectify does well

  • External attack surface management plus DAST in one platform
  • Crowdsource payloads from 400+ ethical hackers
  • REST and GraphQL API scanning
  • Published pricing from a free tier to €15,000/year
  • Swedish company, EU jurisdiction

Where Detectify falls short

  • Finds vulnerabilities rather than blocking attacks, not a WAF or CDN
  • Standard tier caps at 750 assets and 10 users
  • CI/CD integration reserved for Professional and above
  • Enterprise pricing jumps sharply to €15,000/year

Standout feature. It is the one tool here with a free tier and a complete price list up to enterprise level.

#5 Pentest-Tools.com

Bucharest, Romania Founded 2017 From $96/month (NetScan), $140/month (AppScan), $190/month (Exploit), by asset count Demo on request

Best for: Pentesters and security teams that run their own tests and want evidence and reports

  • Operating company. PENTESTTOOLS S.A.
  • Jurisdiction. EU (Romania)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. Self-run testing; complements HackerOne and Bugcrowd

Pentest-Tools.com is a toolkit sold by PENTESTTOOLS S.A. of Bucharest, headquartered there since 2017 according to its about page. The company says it has more than 2,100 customers in 119 or more countries. You buy scanners and exploiters, and you run the tests yourself, so there is no researcher crowd and no triage of outside reports.

Plans are priced by asset count: NetScan from $96 a month for 16 assets, AppScan from $140 for 5 assets and Exploit from $190 for 5 assets, with yearly billing quoted at ten months. All plans include API access, unlimited rescans, team access and integrations, and Exploit adds import of Burp Suite findings. The report generator is an add-on, prices are in US dollars, and AI pentests and the MCP server are marked new on the site.

What Pentest-Tools.com does well

  • Prices published by asset count
  • Wide tool range from recon to exploitation
  • Report generator and Burp import
  • Romanian S.A. as contracting entity
  • REST API and integrations on all plans

Where Pentest-Tools.com falls short

  • No researcher crowd or triage service
  • Prices quoted in US dollars
  • Report generator is an add-on
  • Some features marked new

Standout feature. Every plan carries unlimited rescans and an API, with the price set by how many assets you scan.

#6 Zerocopter

Groningen, Netherlands Pricing on request Demo on request

Best for: Dutch and Benelux organisations that want bounty, pentest and CVD from one local vendor

  • Operating company. Zerocopter B.V.
  • Jurisdiction. EU (Netherlands)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. HackerOne, Bugcrowd

Zerocopter is a Dutch security company that offers four programmes together: a coordinated vulnerability disclosure policy, recon for new and forgotten systems, pentests with a formal report, and a bug bounty with vetted hackers. The terms of sale name Zerocopter B.V. as the contracting party and define researchers as third-party suppliers, so the customer never contracts with an individual hacker.

Its legal documents are public: terms of sale (version of 19 July 2024), a privacy and cookie statement, a disclosure policy and a researcher code of conduct. The two legal pages give different cities, Amsterdam and Groningen, so confirm the address in the order form. No prices, researcher numbers, founding year or hosting location appear on the pages checked, and parts of the site are in Dutch.

What Zerocopter does well

  • Four programs from one Dutch contracting entity
  • Terms of sale and CVD policy published
  • Recon service for forgotten assets
  • Researchers contracted through Zerocopter, not individually
  • Entry route via CVD policy

Where Zerocopter falls short

  • No prices published
  • Hosting location not stated
  • No researcher numbers published
  • Legal pages list two different cities

Standout feature. It frames the offer as a ladder from a disclosure policy up to a bounty, so a first-time buyer can start small under one Dutch contract.

#7 SignalFisher

Lucerne, Switzerland Pricing on request Demo on request

Best for: Swiss and DACH regulated companies replacing yearly pentests with a continuous program

  • Operating company. SignalFisher AG
  • Jurisdiction. Switzerland (adequacy decision, outside the EEA)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. HackerOne, Bugcrowd

SignalFisher is the new name of Bug Bounty Switzerland, shown by a banner on its site, and the imprint names SignalFisher AG at Morgartenstrasse 3 in Lucerne with register number CHE-218.065.572. The company says its roots go back to 2015. The about page names the three co-founders and lists Direttissima Growth Partners and Deutsche Beteiligungs AG as growth partners, the only source we checked for ownership.

The programme runs in three steps: scoping from business context and regulation, testing by vetted researchers against the external attack surface, and interpretation with reports, trend analysis and recommended actions. The site quotes the CISO of Helvetia Baloise Group about a partnership since 2021 and shows Swiss Post and Stadler as customers. Prices, hosting and researcher numbers are not published, and you do not set the reward grid yourself.

What SignalFisher does well

  • Swiss AG with commercial register number published
  • Scoping and interpretation included in the program
  • Vetted researchers and in-house experts
  • Continuous rather than point-in-time testing
  • Named co-founders and advisory board

Where SignalFisher falls short

  • No prices published
  • Hosting location not stated
  • Managed model gives less control over the reward grid
  • Switzerland is outside the EU

Standout feature. It sells scoping and interpretation of the results as part of the programme, where a classic bounty platform leaves both to the buyer.

#8 Ethiack

Coimbra, Portugal Pricing on request Demo on request

Best for: Teams that want continuous automated pentesting with proof-of-exploit instead of a yearly snapshot

  • Operating company. Ethiack, S.A.
  • Jurisdiction. EU (Portugal)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. HackerOne, Bugcrowd, point-in-time pentests

Ethiack is a testing engine from Coimbra, Portugal, run by Ethiack, S.A. under registration number 516856146. Its agentic AI pentester, called Hackian, replaces scheduled tests with autonomous ones that, according to the vendor, trigger on code pushes, infrastructure changes and new knowledge. It maps internal, external and third-party assets and lists reports for NIS2, DORA, SOC 2, ISO 27001 and PCI.

Findings are described as validated for exploitability and come with a proof of exploit and remediation guidance. Case studies name ANA Aeroportos, Bluepharma and Universidade do Porto; the quoted figures, such as a 650 percent return, are vendor claims. There is no crowd or reward grid, no published price, no stated hosting location, and the privacy policy page we checked is dated 2022.

What Ethiack does well

  • Proof-of-exploit attached to confirmed findings
  • Event-triggered continuous testing
  • Attack surface mapping with third-party assets
  • Compliance reports for NIS2 and DORA
  • Portuguese S.A. with registration number published

Where Ethiack falls short

  • No researcher crowd or reward grid
  • No prices published
  • Hosting location not stated
  • Performance figures are vendor claims

Standout feature. Each confirmed finding comes with a proof of exploit, so a human does not have to reproduce it before the ticket is opened.

#9 Securitum

Krakow, Poland Founded 2009 Time and materials EUR 640 to 890 per man day; fixed projects typically EUR 3,500 to 14,000 (vendor pricing page) Demo on request

Best for: Teams that want a manual pentest with a transparent price range

  • Operating company. Securitum Audyty Sp. z o.o.
  • Jurisdiction. EU (Poland)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. HackerOne, Bugcrowd, pentest-as-a-service

Securitum is a Krakow penetration testing firm, Securitum Audyty Sp. z o.o., whose about page gives 2009 as its founding year and almost 2,000 pentests in the last three years. It lists web, mobile, infrastructure and cloud pentests, red teaming, source code review, configuration analysis, OSINT, SSDLC implementation and trainings, and publishes example reports.

The pricing page is the most open in this list: EUR 640 to 890 per man day on time and materials, and EUR 3,500 to 14,000 for typical fixed projects of one to four weeks. These are ranges, not quotes, and the work is a point-in-time test by Securitum's own team. There is no bounty pool or researcher crowd, and the company describes a focus on Central and Eastern Europe.

What Securitum does well

  • Day rates and fixed ranges published
  • Polish sp. z o.o. with register number published
  • Wide scope list from web to red teaming
  • Public reports as examples
  • Trainings available

Where Securitum falls short

  • Point-in-time testing only
  • No researcher crowd or bounty
  • Prices are ranges, not quotes
  • Focus on Central and Eastern Europe

Standout feature. It publishes day rates and project ranges in euros, which almost no other vendor in this category does.

#10 Patchstack

Pärnu, Estonia See website; separate pricing page for mitigation Demo on request

Best for: WordPress plugin and theme vendors that need a managed disclosure channel

  • Operating company. Patchstack OÜ
  • Jurisdiction. EU (Estonia)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. HackerOne VDP, Bugcrowd VDP (for the WordPress ecosystem)

Patchstack is an Estonian company, Patchstack OÜ (register code 14331217), based in Pärnu, and its terms apply Estonian law to customers outside the Americas and Delaware law to those headquartered in North, Central or South America. The scope is narrow: vulnerabilities in WordPress and the wider open-source ecosystem, not a company's own web estate.

The bounty page lists a guaranteed monthly pool of USD 10,000 and zero-day payouts up to USD 33,000, paid by PayPal, Bitcoin or Ethereum. Researchers report through Patchstack, which assigns the CVE in their name. The managed disclosure product takes over report handling for maintainers, and the site says it manages security for 1,134 plugins. The pages checked give no hosting location.

What Patchstack does well

  • Estonian OÜ with register code published
  • Managed VDP takes over report handling
  • CVEs assigned in the researcher's name
  • Public vulnerability database
  • Mitigation rules for hosts

Where Patchstack falls short

  • WordPress and open-source scope only
  • Rewards in USD, paid by PayPal or crypto
  • No hosting location stated
  • Delaware law applies to customers in the Americas

Standout feature. It assigns the CVE in the researcher's name and runs a public vulnerability database for the WordPress ecosystem.

#11 Vaadata

Lyon, France Founded 2014 Quote on request Demo on request

Best for: French and European teams that want a human-led pentest or red team from a French SARL

  • Operating company. VAADATA SARL
  • Jurisdiction. EU (France)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. HackerOne, Bugcrowd, pentest-as-a-service

Vaadata is a Lyon offensive-security firm, VAADATA SARL, registered under RCS 797 558 590, which says it was created in 2014 and is financially independent. It claims more than 800 clients. The tests run as black, grey or white box and cover web, mobile, cloud, infrastructure, IoT, social engineering and LLM systems, including RAG, agents and MCP servers.

Red team audits test detection and reaction against realistic attack scenarios, and assumed breach exercises start from a compromise. There is no bounty, no crowd and no published price, only a quote request. The legal notices state that the marketing website is hosted by Kinsta Inc. in the United States; that concerns the website, not engagement data, but it is worth a question during procurement.

What Vaadata does well

  • French SARL with register number published
  • Wide pentest scope including LLM and IoT
  • Red team and assumed breach offered
  • Financially independent per its own about page
  • Site in French and English

Where Vaadata falls short

  • No bounty or crowd
  • No published prices
  • Point-in-time engagements
  • Marketing website hosted by a US company

Standout feature. It lists a dedicated LLM pentest for RAG, agents and MCP servers as its own service alongside the classic scopes.

Is a bug bounty the right thing to buy, or a pentest?

They answer different questions. A pentest is a time-boxed examination of a defined system by a named team, and it ends with a report. Securitum describes fixed projects of one to four weeks, and Vaadata runs black, grey and white box tests with a red team option. You learn what that team could find in those weeks, which is what an auditor or a release gate usually needs.

A bounty keeps working after the report. Researchers keep looking at the live system and are paid only for valid findings, which suits a product that changes every sprint. YesWeHack, Intigriti and Yogosha are the three crowd platforms. Yogosha sits in between, since it sells fixed-cost pentests next to pay-per-bug programmes from the same vetted pool.

Most mature teams end up with both. A first-time buyer is often better off starting with a disclosure policy or one pentest and adding a bounty when the backlog of known issues is short enough to absorb new reports.

How do the pricing models differ across European platforms?

Four models appear. Quote-only is the most common: YesWeHack, Yogosha, Zerocopter, SignalFisher, Ethiack and Vaadata publish no price, and Intigriti publishes plan names (Core, Premium, Enterprise) without numbers.

Day rates are the Securitum model, EUR 640 to 890 per man day, or EUR 3,500 to 14,000 for a typical fixed project. Tool subscriptions are the Pentest-Tools.com model, from $96, $140 and $190 a month by asset count. Tiers are the Detectify model: a free Starter, then EUR 2,500, 5,000 and 15,000 a year.

Bounty spend is a second cost on top of any platform fee, because rewards go to researchers. Yogosha says its bounty pays per valid vulnerability while its pentest service has a fixed cost. Patchstack quotes its own reward pool in US dollars. Ask every vendor to separate platform fee, triage cost and reward budget in the quote, so you can compare like with like.

Where does the data go, and which vendors say so?

A bounty inbox holds hostnames, proof-of-concept requests and screenshots. Hosting is therefore the question to ask first, and only YesWeHack answers it on its trust page: EU only, in a SecNumCloud-qualified private cloud with European providers. Intigriti explains that stored data is encrypted at application level but does not state a hosting country on the pages we checked.

For Yogosha, Zerocopter, SignalFisher, Ethiack, Securitum, Patchstack, Vaadata and Pentest-Tools.com the pages checked do not name a hosting location, so ask for it and for a sub-processor list. Zerocopter's privacy statement says transfers outside the EEA rely on standard contractual clauses, and Vaadata's legal notices say its marketing site is hosted by Kinsta Inc. in the United States. A European contracting entity gives you European law on the contract, which is a different thing from knowing where the bytes sit.

How do you move from HackerOne or Bugcrowd to a European platform?

HackerOne Inc. is a Delaware corporation, and its General Terms and Conditions apply Delaware law and Delaware courts. Moving means rewriting the policy and scope on the new platform, exporting your report history for your own records, and re-inviting researchers who proved useful. YesWeHack and Intigriti, with open communities, are the easiest landing places for researchers who already work on public programmes.

Run both channels for a quarter and publish the new contact in your security.txt. Reputation and rankings stay with the old platform, so a researcher who is top-ranked there starts again. The vetted-pool vendors, Yogosha and SignalFisher, build their own groups, so expect a different set of testers instead of a transfer of the old ones.

When should you not switch to a European platform?

Stay where you are if your programme depends on the largest possible public crowd and nobody in legal has objected to Delaware terms. The vendors here state researcher numbers between a few hundred and above 160,000, and a large public programme draws on numbers. Zerocopter publishes none, Yogosha cites 1,100 or more for pentests and 800 or more in its private bounty community.

Do not switch either if you need a general bounty from a vendor whose scope is narrower than yours. Patchstack takes WordPress and open-source reports only, and Ethiack does not run a reward programme at all. Check the scope before the contract, because moving a programme twice costs more than staying put once.

How do these tools fit with scanners and the rest of your security stack?

Bounty platforms plug into ticketing. YesWeHack lists Jira, ServiceNow, GitHub, GitLab and Azure DevOps integrations, SAML 2.0 single sign-on and a fixed-IP VPN for hunters, which lets your firewall allow-list test traffic. Intigriti and Yogosha describe integrations and dashboards with retests.

Scanners fill the gaps between human tests. Detectify maps external assets and tests them, with REST and GraphQL API scanning from its Standard tier and CI/CD integration from Professional. Pentest-Tools.com offers an API on all plans and Burp Suite import. Ethiack goes further and ties tests to code pushes and infrastructure changes, with reports for NIS2, DORA, SOC 2, ISO 27001 and PCI. A sensible stack uses one scanner, one human channel and one place where findings turn into tickets.

How we selected and ranked these 11 tools

Every tool on this page is in the European Purpose directory, which means the operating company is established in Europe and we have verified that from the company register or the vendor's own legal notice rather than from a marketing page. Tools headquartered outside Europe are not eligible, however good they are.

  1. Feature verification (weight: 40%). We check each capability against the vendor's own documentation and product pages, and record what the tool does rather than what the category is assumed to include.
  2. Ease of adoption (weight: 30%). Integrations, published API access, trial availability and how much configuration stands between signing and a usable result.
  3. Value and transparency (weight: 30%). Published pricing counts in a vendor's favour; quote-only pricing is recorded as quote-only rather than estimated. We weigh what a buyer gets for the entry price, not the headline feature count.
  4. Editorial review. Every page is researched and drafted with AI assistance, and the compliance and pricing claims are checked against the vendor's documentation before it is published under the founder's editorial responsibility. The three weights above decide the order; a position is a ranking against the other European tools in this category, not an absolute score.

Vendor-reported outcomes — ROI figures, margin uplift, time saved — are labelled as vendor claims wherever they appear on this page. We have not audited them, and neither has anyone else who quotes them. Read our full editorial process for how pages are re-verified.

Frequently asked questions

YesWeHack ranks first in this directory because it states EU-only hosting in a SecNumCloud-qualified cloud and uses its own triage team, followed by Intigriti in Belgium and Yogosha in France. If you need tests rather than a researcher crowd, Detectify, Pentest-Tools.com, Ethiack, Securitum and Vaadata cover scanning, automated pentesting and manual pentests.

Few do. Detectify lists a free Starter tier and plans at EUR 2,500, EUR 5,000 and EUR 15,000 a year, Pentest-Tools.com starts at $96 a month, and Securitum gives EUR 640 to 890 per man day. YesWeHack, Intigriti, Yogosha, Zerocopter, SignalFisher, Ethiack and Vaadata ask for a quote or demo.

SignalFisher AG is registered in Lucerne, so it is European but outside the EU and the EEA. Switzerland has an adequacy decision for data transfers, which the tool page records. Check the governing law in the order form, because a Swiss contract is not under GDPR by default.

YesWeHack and Intigriti are the closest, with vendor-stated communities of over 160,000 and 150,000 researchers respectively and in-house triage. Both ask for a quote. A very large public programme should compare researcher activity during the trial, because those figures are claims from each vendor.

Patchstack in Pärnu, Estonia, runs a WordPress bounty with a monthly reward pool, a managed disclosure programme for plugin maintainers and a public vulnerability database. It assigns CVEs in the researcher's name. It does not host a custom bounty for a general company website.
