26 Penetration Testing Companies in Poland (2026)

Executive Answer

Poland has a strong mix of specialist offensive-security firms, broader cyber consultancies, and international providers serving Polish organizations. The right choice depends on scope: application testing, cloud, red teaming, OT/ICS, or DORA-aligned TLPT. This 2026 comparison reviews 26 providers using current first-party evidence, separates genuine Polish offices from cross-border delivery, and explains how to compare proposals. DeepStrike is listed first because it publishes this guide; the ordering is editorial, not an independent certification. Buyers should verify the named test team, methodology, reporting, retesting, data handling, and availability before signing.

Disclosure and Evidence Date

Disclosure: DeepStrike publishes this list and lists itself first; list order is not a quality ranking. DeepStrike was assessed with the same public-evidence rubric as every other provider, but this is not an independent ranking. “Best for” labels describe editorial use-case fit, not a guarantee of engagement quality. Provider evidence was checked on November 1, 2026, and each provider’s distinguishing line was rechecked on its own website on November 3, 2026.

Quick Picks

These are starting points, not automatic winners. A provider that is excellent for a Warsaw bank may be a poor fit for a two-week API release, and an application specialist may not be qualified to test a live industrial process safely.

What Changed for Polish Buyers in 2026?

Poland’s amended National Cybersecurity System Act, commonly discussed as the KSC implementation of NIS2, was published on March 2, 2026 and entered into force on April 3, 2026. It expands the population of key and important entities and raises expectations for documented cyber-risk management. The law does not make one generic penetration-test format mandatory for every organization, so scope should follow the entity’s systems, risks, and specific obligations.

For organizations that must self-register rather than being entered automatically, the Ministry of Digital Affairs opened registration on May 7, 2026 and states an application deadline of October 3, 2026. Registration and security implementation are different tasks: a pentest can produce technical evidence, but it does not replace governance, incident reporting, supplier controls, or an information-security management system.

The threat environment also changed. CERT Polska’s official 2025 report records 658,320 reports and 260,783 incidents, up 152% year over year. It classifies 253,238 incidents as computer fraud, representing 97% of handled incidents. Those categories are not a count of exploitable vulnerabilities, but the CERT Polska 2025 data supports a more frequent and risk-based testing program for exposed and high-value systems.

DORA has applied since January 17, 2025. It requires a digital operational resilience testing program across the financial sector, while threat-led penetration testing is reserved for selected financial entities and is generally required at least every three years under DORA Article 26. A standard application pentest and a regulator-aligned TLPT engagement are not interchangeable.

The detailed EU standards for TLPT are set out in Delegated Regulation (EU) 2025/1190. Buyers should ask whether a provider can support threat intelligence, scoped live-system testing, white-team governance, risk controls, evidence, and remediation closure rather than accepting a normal pentest relabeled as TLPT.

GDPR Article 32 requires a process for regularly testing, assessing, and evaluating the effectiveness of technical and organizational security measures. The regulation does not prescribe penetration testing by name, so the test type, frequency, and scope should be justified by risk, processing context, and the systems that protect personal data.

For banks, KNF Recommendation D is more specific: section 9.21 says penetration tests are among the tools that should be used systematically to assess controls in highly significant ICT environments. This is banking supervisory guidance, not a universal rule for every company operating in Poland.

Procurement, clearances, and data handling: public bodies buy testing under the Public Procurement Law, usually with Polish-language documentation and reports. Work that touches classified information requires personnel security clearances and, for companies, an industrial security certificate under the Act on the Protection of Classified Information, which is why several entries below state clearance levels. Incidents at in-scope entities are handled by the three national CSIRTs (CSIRT NASK, which operates CERT Polska; CSIRT GOV; and CSIRT MON), and personal data processed during a test falls under the GDPR, supervised in Poland by the President of the Personal Data Protection Office (UODO).

How We Selected and Ordered the Providers

A company qualified for this comparison only when its current first-party website described a real penetration-testing or closely related offensive-security service. It also needed a Polish office or legal entity, a Poland-based team, or a credible cross-border delivery model for Polish organizations. Directory-only listings and tool resellers without a clearly documented human testing service were excluded.

The editorial rubric weights service evidence and technical depth at 30%, Poland delivery relevance at 20%, scope and specialization at 15%, reporting and remediation transparency at 15%, regulated-sector alignment at 10%, and public-evidence recency at 10%. The list does not score private proposals, undisclosed tester experience, or customer references that cannot be checked publicly.

The order is useful for discovery, but the final selection should happen at the engagement level. Ask who will actually perform the test, what percentage of effort is manual, which assets and roles are included, how production risk is controlled, and whether the same team handles retesting. If remediation requires additional engineering capacity, poland team augmentation can support fixes within an existing development team while the penetration-testing provider independently validates the results.

Match the Engagement to the Requirement

Do not start procurement with “we need a pentest.” Start with the decision the report must support.

For a product scope, a dedicated web application penetration test should include authenticated roles, APIs, authorization boundaries, business logic, and validated impact—not only an unauthenticated scanner output.

A mobile application penetration test should cover the app, the backend APIs it relies on, local storage, platform-specific controls, and relevant iOS or Android behavior.

For AWS, Azure, or Google Cloud, a cloud penetration test should define identity paths, tenant or account boundaries, allowed techniques, logging, and provider rules before testing starts.

AI-enabled products need scope beyond a conventional web test. An LLM and AI application assessment may need to cover model-facing inputs, tool use, authorization, data exposure, and abuse paths while keeping the engagement defensive and controlled.

Choose red teaming when the objective is to test whether people, processes, and controls can detect and contain a realistic adversary—not when the only requirement is a vulnerability list for one application.

DORA and TLPT: What to Ask a Provider

A DORA financial-entity assessment, a standard pentest, and TLPT serve different objectives. Do not select a TLPT provider based only on a web-application methodology or a generic DORA badge.

AFINE, Securitum, and CyberForces publish specific TLPT offerings, and Pentestica and VIPentest also list TLPT. Other providers may have relevant capabilities, but the proposal must prove the full delivery model. Treat “DORA-ready report” and “DORA TLPT” as different claims.

OT and ICS Penetration Testing Shortlist

OT/ICS testing should begin with architecture, process safety, vendor constraints, and passive discovery. A technique that is routine on a web application can disrupt a controller, engineering workstation, medical device, building system, or production process.

The safest provider is not necessarily the one promising the most exploitation. It is the one that can obtain useful evidence without creating unacceptable operational risk.

How to Compare Penetration Testing Quotes

Price comparisons fail when suppliers quote different assumptions. Give every shortlisted provider the same scoping pack and convert each response into a common table.

A continuous penetration testing model can make sense for products that release frequently, but it should not be purchased on the word “continuous” alone. Ask what triggers human testing, what assets remain covered, how quickly changes are reviewed, and how results flow into remediation.

Local Provider or Remote Specialist?

A Polish office can simplify onsite work, Polish-language reporting, procurement, data-handling discussions, and coordination with local stakeholders. It is especially valuable for physical, social-engineering, OT, or highly regulated engagements.

A remote specialist can be the better choice for a cloud service, API, SaaS platform, or niche technical problem when location does not constrain access. The tradeoff is not local versus good; it is delivery fit, communication, legal contracting, availability, and proven expertise for the exact target.

For either model, confirm the legal entity signing the contract, where evidence is stored, who can access it, which time zone governs urgent escalation, and whether subcontractors are used.

Frequently Asked Questions

How much does penetration testing cost in Poland?

There is no defensible market-wide price for a “pentest” because the unit is undefined. Cost changes with asset count, roles, source access, cloud accounts, tester-days, production restrictions, reporting, travel, and retesting. Compare fixed-fee, day-rate, and subscription proposals only after every provider prices the same scope. Ask for effort by workstream and list every inclusion and exclusion.

Is penetration testing legally required in Poland?

Sometimes a specific obligation, supervisory expectation, contract, or sector framework makes technical testing necessary, but most laws do not prescribe one universal pentest. The KSC Act requires risk-management and effectiveness measures for in-scope entities; GDPR requires regular evaluation of security measures; DORA includes resilience testing and TLPT for selected financial entities; and KNF Recommendation D specifically discusses systematic penetration tests for highly significant banking ICT environments.

What is the difference between a pentest, red team, and TLPT?

A penetration test searches a defined asset set for exploitable vulnerabilities. A red team pursues agreed objectives to test prevention, detection, and response across people, process, and technology. TLPT is a regulated, threat-led exercise for designated financial entities with specific governance, intelligence, live-system, evidence, and remediation requirements. They overlap technically but are not interchangeable deliverables.

Should we choose a Polish company or an international provider?

Choose based on the work. Local presence helps with onsite, physical, social-engineering, OT, language, contracting, and stakeholder coordination. International or remote delivery can be effective for web, API, cloud, code, and specialist product testing. Verify the contracting entity, data location, working hours, assigned testers, and ability to support urgent remediation before deciding. For a Baltic example of the same local-versus-remote choice, see our comparison of penetration testing companies in Lithuania.

Which penetration-testing certifications should we require?

Certifications such as OSCP, OSWE, OSEP, CREST, GIAC, and cloud-specific credentials can support a due-diligence decision, but they do not prove that the assigned tester fits the target. Ask for role-specific CVs, relevant project experience, a sanitized sample report, and a technical scoping conversation. Company-level ISO certification covers management processes, not the depth of every individual test.

How long does a penetration test take?

Duration depends on effort and access, not only calendar days. A focused assessment may use a small number of tester-days, while a multi-application, infrastructure, red-team, OT, or TLPT program can run for weeks or months. Ask the quote to separate scoping, active testing, quality review, reporting, remediation support, and retesting so a short testing window is not confused with complete delivery.

How often should penetration testing be performed?

Use risk and change frequency. High-value assets should be tested after material releases, architecture changes, identity redesigns, major cloud changes, or exposure shifts, in addition to any contractual or regulatory cadence. An annual test may support a stable system, while a fast-moving product may need release-triggered or continuous coverage. DORA TLPT cadence for designated entities is a separate regulatory requirement.

Conclusion

The Polish market offers strong specialist boutiques, industrial-security teams, network engineers, major consultancies, and international providers. The best choice is the team whose evidence, scope, testing depth, production controls, reporting, and retesting match the system and decision you need to protect.

Use the comparison to build a shortlist, then run the same technical scoping call and quote template with each provider. A well-defined penetration testing engagement is easier to compare, safer to execute, and more likely to produce findings your teams can actually fix.
