Top Penetration Testing Companies in Ukraine (2026)

The top penetration testing companies in Ukraine combine deep offensive-security talent with a rare kind of experience: many Ukrainian teams have worked under sustained cyber pressure since 2022. Ukraine's technology sector has produced boutique appsec shops, Web3 audit specialists, and large enterprise consultancies, and this guide profiles established providers alongside honest guidance on how to pick one. Whether you need a one-off web application test, continuous coverage, or a blockchain audit, the shortlist below explains who does what, what credentials to check, and how to match a provider to your risk.

Comparing providers beyond Ukraine? Our worldwide list of penetration testing companies covers firms that deliver testing across regions.

Disclosure: DeepStrike, the publisher of this guide, is a penetration testing provider and is included in this list. Weigh our entry the way you would any vendor's description of its own service, and compare scope, sample reports and references for every provider before you buy. DeepStrike publishes this list and lists itself first; list order is not a quality ranking.

Updated: November 2026. Company profiles were rewritten from each vendor's official website; verify current scope and certifications directly before you sign, because service lines change.

Why Ukraine is a serious place to buy penetration testing

Ukraine has been one of Europe's largest software-engineering hubs for two decades, and cybersecurity grew alongside that base. The country has OWASP chapters in Kyiv and Lviv, a strong bug-bounty and CTF culture, and a talent pool certified in the same credentials buyers look for anywhere: OSCP, OSEP, CREST, CISSP, and GPEN.

What sets the market apart in 2026 is operational experience. Since 2022, Ukrainian defenders have worked through sustained, real-world attacks on critical infrastructure, government, and private industry, coordinated in part through the State Service of Special Communications and Information Protection. That pressure has hardened a generation of practitioners who understand how attackers actually behave, not just how they behave in a lab. For a buyer, that experience can be relevant; confirm it through the assigned testers and sample reports.

Two practical caveats belong up front. First, wartime conditions mean you should confirm a provider's delivery continuity, data-residency arrangements, and where its team physically operates, since many firms now run distributed across Ukraine, Poland, and the wider EU. Second, "based in Ukraine" and "serves Ukrainian companies" are different things. Some of the strongest options for a Ukrainian business are international penetration testing services providers that deliver remotely, which is why the list below includes both.

Ukraine Regulatory and Procurement Context

Ukraine's framework rests on the Law "On the Basic Principles of Ensuring Cybersecurity of Ukraine" (2017). The State Service of Special Communications and Information Protection (SSSCIP) shapes and implements policy on cyber protection of critical information infrastructure, and CERT-UA, founded in 2007, is a unit of SSSCIP's State Center for Cyber Defense. Critical-infrastructure and state-system operators should confirm which SSSCIP requirements apply before scoping a test, and agree with the provider how a live compromise found during testing will be reported to CERT-UA.

Public bodies buy through Prozorro, Ukraine's public procurement system, so a provider bidding for state work needs a contracting entity that can take part in its tenders. Many Ukrainian providers now contract through Polish or other EU entities, which matters for EU clients: the GDPR applies to their data, and Ukraine is not on the European Commission's list of adequacy decisions, so access to EU personal data from Ukraine needs a transfer mechanism such as standard contractual clauses. EU financial entities using a Ukrainian provider must also apply the ICT third-party contract rules in DORA (Regulation (EU) 2022/2554), applicable since 17 January 2025. Facts in this section were checked on 3 November 2026.

How we evaluated these companies

We prioritized providers with a demonstrable penetration testing practice (not just a security-adjacent IT shop), verifiable certifications, and a public track record. The criteria that matter most when you compare vendors:

• Look for human-led, manual testing. Automated scanning finds known issues; skilled testers find business-logic flaws, chained exploits, and privilege escalation that scanners miss.
• Check individual and firm certifications. OSCP, OSEP, and CREST signal hands-on offensive skill; ISO 27001 and SOC 2 signal the provider handles your data responsibly.
• Confirm the deliverable. A good penetration testing report ranks findings by real risk, includes reproduction steps and evidence, and comes with a retest to verify fixes.
• Match the specialty to your stack. Web and API, mobile, cloud, network, IoT, automotive, and Web3 are distinct disciplines. Buy the one you actually need.
• Verify compliance mapping. If you answer to SOC 2, ISO 27001, PCI DSS, HIPAA, or GDPR, the provider should map findings to those frameworks.

How we built this Ukraine list: we started from firms that publish penetration-testing services and are Ukrainian-founded or keep a team in Ukraine (application-security boutiques, Web3 auditors, MDR providers, and the security practices of large Ukrainian software-engineering companies), plus DeepStrike as publisher. Because many Ukrainian firms now contract through Polish or other EU entities, we recorded each firm's published addresses and legal footprint alongside its services, credentials, and limits, using its own website, last checked in November 2026. This is desk research; we did not commission tests or score the providers.

The comparison below is a snapshot to orient your shortlist; the profiles that follow add the detail.

How to choose the right penetration testing partner

Use the shortlist as a starting point, then narrow it with a structured comparison rather than a gut call. If you are scoping web application penetration testing, our guide to the penetration testing methodology explains how engagements are run.

1. Define the scope and the asset first. A web app, a mobile app, a cloud environment, an internal network, and a smart contract each need different expertise. Pick providers who specialize in your specific asset.
2. Ask for a sample report. The report is the product. Confirm it ranks findings by real-world risk, includes reproduction steps and evidence, and gives remediation guidance a developer can act on.
3. Verify certifications, then verify the individuals. A firm-level ISO 27001 or CREST accreditation is good; ask how many testers on your engagement hold OSCP or OSEP, because names on the badge should also be names on the report.
4. Confirm a retest is included. Fixing a finding you cannot verify is not fixing it. A retest that validates remediation should be part of the engagement, not an upsell.
5. Clarify data handling and continuity. Ask where the team operates, how your data is stored and transmitted, and what happens if delivery is disrupted. For distributed Ukrainian teams in 2026, this is a fair and expected question.
6. Decide point-in-time versus continuous. A single annual test is a snapshot; if you ship code frequently, a continuous or PTaaS model catches issues between releases. The numbers on how often organizations test are worth reviewing in our penetration testing statistics roundup.

If you are still mapping the basics, our primer on vulnerability assessment and penetration testing (VAPT) explains how scanning and manual testing fit together, and our penetration testing companies in Poland page shows how the same evaluation logic applies in another European market.

Red flags to watch for

The failure modes are the same whether a provider sits in Kyiv or anywhere else, and spotting them early saves you from paying for a report that changes nothing. Watch for these:

• A "penetration test" that is really just a scan. If the proposal has no manual testing, no named testers, and a turnaround measured in hours, you are buying an automated vulnerability scan with a nicer cover page. Ask directly how much of the work is done by hand.
• No sample report or references. A firm confident in its work will show you a redacted report and connect you with past clients. Reluctance here is a signal.
• Certifications on the website but not on the engagement. A logo wall means little if none of the testers assigned to you hold the credentials. Ask who, specifically, will do the work.
• A retest treated as a paid extra. If validating your fixes costs more, the engagement ends before you know whether anything is actually resolved.
• Vague scope and a flat price. Good providers scope carefully, because scope drives both cost and coverage. A single number with no breakdown usually hides assumptions you will discover later.
• No answer on data handling. Your test data and findings are sensitive. A provider that cannot clearly explain where data lives, who can see it, and how it is destroyed afterward has not thought about your risk.

None of these are unique to Ukrainian firms; they are the universal tells of a weak engagement. Use them as a checklist against every shortlisted vendor, local or international.

The bottom line

Ukraine offers a deep pool of penetration testing talent, from appsec boutiques like Berezha Security Group and Iterasec to Web3 specialists like Hacken and larger providers like ISSP and N-iX. The right choice depends on your asset, your compliance needs, and whether you want a local boutique or an international PTaaS partner delivering remotely. Shortlist two or three from the profiles above, ask each for a sample report and a scoped proposal, and choose on the evidence rather than the marketing.

Frequently asked questions

Which is the best penetration testing company in Ukraine?

There is no single best; the right firm depends on what you are testing. For application security, Berezha Security Group and TechMagic are standouts. For Web3 and smart contracts, Hacken specializes. For testing alongside managed security or large engineering programs, ISSP and N-iX have the reach. For human-led application, cloud, and infrastructure testing delivered remotely, DeepStrike (the publisher of this guide) is an option. Match the specialist to your asset.

Are Ukrainian penetration testing companies reliable given the war?

Many are, but you should confirm delivery continuity and data handling explicitly. Numerous Ukrainian firms now operate distributed across Ukraine, Poland, and the wider EU, and Ukrainian defenders have extensive real-world experience against active threats. Ask each provider where its team operates and how it guarantees continuity before you sign.

What certifications should a Ukrainian pentest provider have?

Look for hands-on offensive certifications on the individual testers, such as OSCP, OSEP, and GPEN, and firm-level standards such as CREST accreditation, ISO 27001, and SOC 2. Certifications are a filter, not a guarantee, so pair them with a sample report and references.

How much does penetration testing cost in Ukraine?

Cost depends on scope, asset complexity, and the depth of manual testing, not the country. A focused web-application test is far cheaper than a multi-asset program with red teaming. Get scoped, fixed quotes from two or three providers and compare what is included, especially whether a retest is part of the price.

Should I hire a local Ukrainian firm or an international provider?

Both are valid. A local boutique can offer close collaboration and deep regional knowledge; an international provider can deliver testing remotely, so compare its reporting workflow and whether continuous options are offered. Decide based on your asset, your compliance requirements, and how you prefer to work, then compare shortlisted providers on the same criteria.
