Lithuania Penetration Testing Companies: 10 Compared (2026)

Penetration testing companies in Lithuania include Vilnius-based firms such as Hackdeflect, Baltic Amadeus, Critical Security, ENNEID, and SolutionLab, and providers that test remotely for Lithuanian clients, including DeepStrike (the publisher of this guide), Secmentis, Team Secure, EC-Council Global Services, and CyberAudit. This 2026 guide compares all ten on the same evidence: Lithuania relationship, testing scope, credentials, reporting, and retesting. In Lithuanian, the service is usually called įsilaužimų testavimas or skverbties testavimas, so search tenders and provider sites for both terms.

Lithuanian organizations evaluating penetration testing providers should compare more than location or a directory rating. The strongest shortlist starts with verified service scope, the people actually assigned to the test, manual exploit validation, reporting quality, data-handling terms, remediation support, and retesting. This 2026 guide compares providers with evidence that they either operate in Lithuania or explicitly serve Lithuanian customers. It also separates ordinary penetration testing from regulated testing requirements so security, procurement, and engineering teams can choose a provider that fits their technical and assurance needs.

Comparing providers beyond Lithuania? Our global list of top penetration testing companies covers firms that deliver testing across regions.

Publisher and listing disclosure: This guide is published by DeepStrike. DeepStrike is listed first as a disclosed editorial placement by the publisher. That position is not an independent award, a customer-voted result, or a claim that DeepStrike is the right provider for every buyer in Lithuania. The same evidence categories were applied to every provider, and the provider profiles reflect official company websites reviewed in November 2026. DeepStrike publishes this list and lists itself first; list order is not a quality ranking.

How This Lithuania Provider List Was Built

A provider qualified only when the research record supported an active penetration-testing or closely related offensive-security service and a defensible Lithuania relationship. We separated providers into three groups: Lithuania-headquartered firms, providers with a verified Lithuanian legal entity or office, and international providers whose first-party materials explicitly say they serve Lithuania. A localized page alone was not treated as proof of a Lithuanian office.

Evidence quality mattered more than list length. First-party service pages were used for active services and delivery claims; official directories were preferred for provider-level accreditation; and directory listings were not accepted as the sole proof of location, price, team size, clients, or quality. Where a capability, credential, price, or on-site option was not directly established, the article tells buyers to verify it instead of filling the gap with an assumption.

For this Lithuania edition, the candidate pool combined providers that publish penetration testing services from a Lithuanian address (Hackdeflect, Baltic Amadeus, Critical Security, ENNEID, and SolutionLab, all in Vilnius) with international firms that run a Lithuania-specific page or site (Secmentis, Team Secure, EC-Council Global Services, and CyberAudit). Each provider's own service, contact, and about pages were re-checked on 3 November 2026 against five criteria: a verifiable Lithuania relationship, published testing scope, stated methodology or reporting, named credentials or accreditation, and how retesting and data handling are described. Regulatory context was checked the same day against European Commission, ECB, EDPB, and EUR-Lex sources.

The “best fit” descriptions below are editorial buyer guidance inferred from the verified scope and delivery evidence. They are not provider endorsements or promises of outcomes. Before contracting, buyers should still verify the named testers, subcontractors, data location, rules of engagement, insurance where relevant, retesting terms, and the exact legal entity signing the statement of work.

Comparison of the Top Penetration Testing Companies Serving Lithuania

Quick Picks: Which Lithuania Pentest Provider Fits Your Need

If you already know what you need tested, start with the providers whose published evidence matches it. Each pick below restates what the provider profiles further down document. It is a starting point for a shortlist, not a quality ranking or an endorsement.

Whichever row fits, ask two or three providers to quote the same written scope. The buying checklist later in this guide shows what that scope should contain.

Provider Profiles

1. DeepStrike: Human-led testing with remediation collaboration

Public offering: DeepStrike's penetration testing services describe human-led testing across applications, cloud environments, and infrastructure, supported by a findings and collaboration platform.

Buyer fit: Lithuanian organizations with mixed application and infrastructure scope, or that want to step up to red teaming.

What sets it apart in Lithuania: Critical Security's infrastructure page explains how internal testing can run remotely through a customer-issued VPN and describes a post-mitigation re-check that updates the report, which is more published process detail than several local alternatives offer.

5. Secmentis: Remote penetration testing for Lithuanian buyers

Public offering: Secmentis offers external, internal, mobile app, web app, physical, and wireless penetration testing, plus incident response, security hardening, and vulnerability assessment. It describes manual and automated testing with custom-built and standard tools, tailor-made tests, and fixed-price quotes.

Lithuania relevance: Secmentis Ltd. states its penetration tests are available in Lithuania, including Vilnius, Kaunas, and Klaipėda, and can be provided remotely; its site does not publish a Lithuanian address. Confirm the contracting entity, tester locations, and data-transfer terms in the agreement.

Certifications: Secmentis states its team members individually hold accreditations including CISA, CEH, and SANS GIAC certifications.

Official sources: https://www.secmentis.com/lithuania/penetration-testing; https://www.secmentis.com/contact

Buyer fit: Buyers comfortable with remote delivery who want fixed-price network, application, wireless, or physical testing.

What sets it apart in Lithuania: Secmentis names coverage beyond the capital, including Kaunas, Klaipėda, Šiauliai, and Panevėžys, and advertises fixed pricing agreed before work starts, which suits regional buyers who want a remote engagement with a known cost.

6. ENNEID: Vilnius-based penetration testing and security training

Public offering: ENNEID lists penetration testing of systems, networks, web applications, and mobile applications, including manual penetration tests, alongside cybersecurity consulting and employee security training. It states that each engagement starts by agreeing the test scope and rules of engagement with the client.

Lithuania relevance: ENNEID lists its head office at Laisvės pr. 3, Vilnius, and states it was founded in 2022; its site does not name the legal entity. Confirm the contracting entity, assigned testers, and data handling in the agreement.

Official sources: https://enneid.com/; https://enneid.com/contact-us/

Buyer fit: Smaller Lithuanian organizations that want web or mobile application testing combined with staff security awareness training.

What sets it apart in Lithuania: ENNEID is the youngest Vilnius firm in this list by its own account and pairs testing with employee security training, which can suit smaller organizations that want one local supplier for both.

7. SolutionLab: CREST-accredited testing from a Lithuanian IT consultancy

Public offering: SolutionLab lists web application and web services, mobile, internal and external network, wireless, cloud, Citrix and thick client, social engineering and physical security testing, plus source code review, red team simulation, and threat-led penetration testing (TLPT) services.

Buyer fit: Organizations, particularly in financial services, that want CREST-accredited testing from a Lithuanian provider.

What sets it apart in Lithuania: SolutionLab is the only provider in this shortlist that states company-level CREST penetration testing accreditation, and it also lists TLPT and red team simulation, which matters to financial-sector buyers who want an accreditation they can check on CREST's register.

8. Team Secure Lithuania: Penetration testing and security staffing

Public offering: Team Secure offers penetration testing of infrastructure, applications, and people using automated and manual tests, with findings and guidance on controls reported to the client. Its wider business focuses on supplying cybersecurity staff and consultants, and it also develops web and mobile applications.

Lithuania relevance: Team Secure runs a Lithuanian website and says it can mobilize consultants in person in Lithuania or remotely, but the entity named on the site is Cybrient Technologies SA in Geneva, Switzerland. Confirm the contracting entity, whether testers are employees or contractors, and data handling in the agreement.

Official sources: https://teamsecure.lt/en/cyber-security-services/penetration-testing

Buyer fit: Organizations that want flexible penetration testing capacity or cybersecurity staff augmentation.

What sets it apart in Lithuania: Team Secure works mainly as a staffing and consultancy model, offering to place penetration testing consultants in person in Lithuania or remotely, which suits teams that need temporary capacity more than a fixed-scope project.

9. EC-Council Global Services (EGS): Remote and on-site VAPT

Public offering: EC-Council Global Services, the consulting arm of EC-Council, offers vulnerability assessment and penetration testing of network infrastructure, web applications, and mobile applications, including internal and external testing and sector-specific tests for telecoms, banking, and healthcare. It states that it combines OWASP, CREST, and OSSTMM standards with manual testing and finding validation.

Lithuania relevance: EGS has a Lithuania page offering local or remote penetration testing for organizations in Vilnius, Kaunas, Klaipėda, and other cities, but it does not publish a Lithuanian office or entity. Confirm the delivering entity, tester locations, and data handling in the agreement.

Official sources: https://egs.eccouncil.org/penetration-testing-in-lithuania/; https://egs.eccouncil.org/contact-us/

Buyer fit: Organizations that want penetration testing from a globally branded consultancy alongside wider security advisory.

What sets it apart in Lithuania: EGS is the consulting arm of the EC-Council certification body and offers sector-specific tests for telecoms, banking, and healthcare, but the recognitions it shows relate mainly to Malaysian and Singaporean schemes rather than an EU or Lithuanian one.

10. CyberAudit: Small UK-based penetration testing firm

Public offering: CyberAudit offers external and internal penetration testing, web application testing, PCI penetration testing, and network segmentation testing. It combines automated tools with manual testing and bases its methodology on OWASP, EC-Council, PCI DSS, ISACA, and ISO guidance.

Lithuania relevance: CyberAudit's Lithuania page says it provides penetration testing in Vilnius and worldwide, and its site gives a contact address in Harrogate, United Kingdom; no Lithuanian office is published. Confirm the contracting entity, tester location, and data handling in the agreement.

Certifications: CyberAudit states its managing director, who performs the testing, holds CEH, PCIP, and CISA certifications.

Official sources: https://www.cyberaudit.eu/penetration-testing-lithuania/

Buyer fit: Smaller organizations needing PCI DSS or network segmentation testing from a small specialist firm.

What sets it apart in Lithuania: CyberAudit is the entry most focused on PCI penetration testing and network segmentation testing, delivered by a small UK firm whose managing director performs the work, which suits card-payment environments with a narrow scope.

Pentest Providers That Cover Lithuania, Latvia, and Estonia

Several providers in this list also publish coverage for the other Baltic states, which helps when one group runs systems in Vilnius, Riga, and Tallinn. Based on their own websites, checked on 5 November 2026:

• Secmentis publishes separate penetration testing pages for Lithuania, Latvia, and Estonia and offers remote delivery.
• CyberAudit publishes Lithuania and Estonia pages and names Latvia and Estonia among the countries where its clients are located.
• SolutionLab says it has served clients across Europe since 2007, especially in the Nordics and the Baltics.
• Hackdeflect presents its penetration testing and red team services for Lithuania and Europe.
• DeepStrike tests remotely, so one team can cover assets in all three countries under a single scope.

One Baltic contract can work, but check four points first: which legal entity signs in each country, whether testers need on-site access in more than one country, which national NIS2 authority each in-scope entity answers to (in Lithuania it is NKSC), and whether one report format will satisfy every auditor. For local alternatives, compare our lists of penetration testing companies in Latvia and penetration testing companies in Estonia.

How to Choose a Penetration Testing Company in Lithuania

Define the exact assets and any regulatory driver (NIS2, DORA, or PCI DSS) first. Then confirm each provider's contracting entity and where testers and evidence sit, verify the named testers' credentials, require manual exploit validation, and compare sample reports, retesting terms, and quotes against the same written scope rather than against location or brand.

Start with the decision you need the test to support. A procurement exercise for a single web application, an internal network, a cloud platform, a mobile product, an adversary-simulation program, and a regulated TLPT engagement are different scopes. DeepStrike's broader vendor-selection guide can help frame the shortlist, but the Lithuania-specific decision should begin with the exact assets, threat assumptions, business constraints, and evidence requirements.

Define the technical scope before comparing names. For a web application, document roles, authentication paths, APIs, business-critical workflows, integrations, and test environments. For infrastructure or cloud, define accounts, subscriptions, tenants, identity boundaries, external exposure, production restrictions, and provider rules. A broad label such as “full pentest” is not a comparable scope.

Choose local presence only when it solves a real requirement. A Lithuania-based entity may simplify contracting, language, travel, or on-site work, while a remote specialist may offer a better technical match for a narrow stack. Ask separately about legal entity, tester location, on-site availability, working language, subcontractors, and where evidence will be stored.

Verify the people, not just the logo. Request the named lead tester, reviewer, relevant practitioner credentials, recent experience with the same technology class, and any subcontractors. Company-level accreditation and individual certifications answer different questions and should not be substituted for each other. The more detailed 25-question penetration-testing buyer checklist can be used during technical evaluation.

Separate manual exploit validation from scanning. Automated discovery can support an engagement, but a penetration test should make clear where qualified humans validate exploitability, test authorization/business logic, examine attack chains, and control the safety of exploitation. Ask what the provider will not test as well as what it will test.

Match the engagement model to change velocity. A one-time assessment can be appropriate for a defined release or assurance event; frequently changing systems may benefit from a repeatable program. Continuous testing should still specify where human testing occurs, how new scope is added, how findings are triaged, and what retesting actually covers.

Do not confuse penetration testing with red teaming. A conventional pentest is normally scoped to find and validate weaknesses in defined assets; a red-team engagement can test broader detection and response objectives under an adversary-simulation model. The authorization, operational-risk controls, objectives, and success criteria should reflect the actual engagement type.

Put authorization and safety in writing. The rules of engagement should define authorized assets, dates, source IPs where relevant, prohibited actions, production-safety constraints, emergency contacts, stop conditions, evidence handling, credential handling, and escalation for critical findings. A vague statement of work is a procurement risk even when the technical team is strong.

Compare report and remediation workflow. Ask for a representative redacted report or a detailed report specification. It should separate executive and technical views, describe evidence and impact, show reproducible steps where safe, prioritize remediation, explain chained risk where relevant, and state how retesting changes finding status.

Normalize commercial assumptions. Two quotes are not comparable if one includes authenticated testing, multiple roles, an API, a staging environment, a retest, and a workshop while the other does not. Ask every provider to price against the same scope and list assumptions, exclusions, travel/on-site costs, evidence-retention terms, retesting, and change triggers. Procurement teams can also use a focused vendor red-flags guide to challenge vague scope or evidence.

Lithuania Regulatory and Procurement Context

Lithuania's cybersecurity obligations should be treated as a scope question, not a marketing shortcut. Lithuania transposed NIS2 by amending its Law on Cyber Security, and the National Cyber Security Centre under the Ministry of National Defence (NKSC, which runs CERT-LT) is the national NIS2 body: the European Commission's NIS2 implementation page for Lithuania shows Lithuania's status as transposed and lists NKSC/CERT-LT as the single point of contact, the national competent authority, and the national CSIRT (page last updated 8 July 2025). Because one body handles both supervision and incident reporting, keep pentest reports, remediation evidence, and retest results in a form you could share with it if asked. The exact obligations depend on the organization, sector, system, role, and applicable implementing rules; this article is not legal advice.

According to NKSC, the amended Law on Cyber Security entered into force on 18 October 2024. NKSC identifies in-scope entities itself and was to add them to the Cybersecurity Entities Register by 17 April 2025. From inclusion, entities are expected to meet the organisational requirements within 12 months and the technical requirements within 24 months, and to commission a cybersecurity audit at least once every three years under NKSC's audit methodology. Ask a provider whether its report can serve as evidence in that audit, rather than assuming a pentest replaces it.

For financial entities, DORA has applied since 17 January 2025, and supervision runs through the authorities already designated under EU financial-sector law. In Lithuania, the Bank of Lithuania has been the single supervisor of the financial sector since it took over capital-market and insurance supervision in 2012, so banks, payment and electronic money institutions, insurers, and investment firms should confirm testing expectations with it. The ECB's TIBER-EU page (checked 3 November 2026) does not list Lithuania among the jurisdictions that have adopted TIBER-EU. When a provider describes its red teaming as based on TIBER-EU, treat that as a description of method rather than of a Lithuanian national program, and ask how any TLPT proposal maps to DORA and Delegated Regulation (EU) 2025/1190.

Testing can expose personal data, such as customer records reached through a vulnerable application. Lithuania's GDPR supervisory authority is the State Data Protection Inspectorate (VDAI) in Vilnius, as listed by the European Data Protection Board. In this shortlist, DeepStrike, Secmentis, EC-Council Global Services, and CyberAudit publish no Lithuanian address, and Team Secure's site names a Geneva entity, so procurement records should state the contracting entity, where testers work, where evidence is stored, and the transfer mechanism if data leaves the EU/EEA.

Public-sector buyers use a fixed procurement channel. The Public Procurement Office (VPT) states that every public procurement procedure, above and below EU thresholds, must run through the Central Public Procurement Information System (CVP IS), except procedures that may be carried out without prior publication, and that all procedures have used the new CVP IS at viesiejipirkimai.lt since 1 December 2024. Suppliers, including foreign firms, must register in CVP IS before they can bid; VPT has said approval can take up to three working days, and the European Single Procurement Document is completed in a separate standalone tool. A provider without a Lithuanian entity can still bid, but it should register well before the tender deadline.

At EU level, NIS2 Article 21 requires appropriate and proportionate cybersecurity risk-management measures and includes assessment of their effectiveness. It does not create one universal annual penetration-testing rule for every entity. For defined digital-sector entities, Commission Implementing Regulation (EU) 2024/2690 provides more specific technical and methodological requirements; security testing can involve different automated and manual methods and may include penetration testing depending on scope.

DORA establishes an ICT risk-management and testing framework for defined financial entities. Threat-led penetration testing is a specialized regulatory regime for selected entities, not a synonym for an ordinary pentest and not a requirement for every Lithuanian company. Where TLPT may apply, the organization should check the current selection criteria, competent-authority process, tester requirements, and Commission Delegated Regulation (EU) 2025/1190 before scoping the engagement.

GDPR Article 32 uses a risk-based approach and refers to regular testing, assessing, and evaluating the effectiveness of security measures where appropriate; it does not universally require a penetration test. PCI DSS is different in that applicable in-scope cardholder-data environments can have explicit penetration-testing requirements, so the current PCI SSC version and requirement text should be checked for the environment. ISO/IEC 27001 supports risk-based information-security management but does not universally require a penetration test by name.

A penetration-test report can support assurance, remediation evidence, or a compliance program. It does not by itself prove compliance, guarantee certification, satisfy every regulator, prevent a future breach, or show that every finding has been fixed.

Penetration Test, Cybersecurity Audit, or Risk Assessment?

Many Lithuanian buyers look for a penetration testing company when the obligation in front of them is an audit or a risk assessment. The three answer different questions, and an NIS2 entity in Lithuania may need all three:

• Risk assessment identifies and rates the risks to your systems and services and decides which controls are proportionate. NIS2 Article 21 lists policies on risk analysis as the first required measure.
• Cybersecurity audit checks whether your controls and processes meet a defined set of requirements. Under the amended Law on Cyber Security, in-scope entities commission one at least every three years under NKSC's audit methodology.
• Penetration test tries to exploit weaknesses in defined systems and produces technical evidence, such as reproduction steps, impact, and retest results, that a risk assessment or audit can rely on.

Ask whether a provider can deliver the audit itself or only the technical testing, and whether its report is structured so your auditor can use it. Our guides to the IT security audit, NIS2 penetration testing, and DORA TLPT requirements explain each obligation in more depth.

Penetration Testing Pricing in Lithuania

There is no defensible national price range in the evidence used for this update, so this guide does not publish one. Directory hourly rates, global averages, and old provider figures are not reliable substitutes for a Lithuania-specific market benchmark.

A comparable proposal should state the number and type of assets, applications, APIs, roles, endpoints, accounts, environments, network ranges, cloud tenants, and testing windows. It should also state the expected manual effort, whether authenticated testing is included, report and workshop deliverables, critical-finding escalation, remediation support, retesting, on-site/travel assumptions, evidence retention, and data-handling constraints.

For DeepStrike specifically, the current penetration testing pricing page can be used to understand published commercial terms before requesting a scope-specific quote. For other providers in this shortlist, this article treats pricing as quote-based or not publicly verified unless a current first-party source is reviewed during procurement.

When comparing bids, ask each provider to price the same statement of work and identify what would trigger a change order. A lower total can reflect a narrower scope, fewer test roles, less manual effort, no retest, a different reporting package, or different data-handling assumptions, not necessarily better value.

Use the questions below to turn a shortlist into a comparable procurement record. For a more extensive interview framework, use the separate DeepStrike buyer guide rather than expanding this article into a full RFP template.

Frequently Asked Questions

Do I need a Lithuania-based penetration testing company?

Not necessarily. A Lithuania-based legal entity or office can help when your procurement process requires local contracting, Lithuanian-language work, or on-site activity. For many application, cloud, and infrastructure scopes, a qualified remote specialist can also be appropriate. Verify the contracting entity, tester location, data handling, language, subcontractors, and on-site requirements separately.

What evidence should I request about the assigned testers?

Ask for the named lead tester and reviewer, credentials relevant to the actual technology, recent comparable experience, and any subcontractors. Do not assume that a company accreditation proves that a particular certified practitioner will perform your test, and do not treat an individual certification as company-level accreditation.

Do NIS2, DORA, or GDPR require every Lithuanian company to run an annual pentest?

No. These frameworks have different scopes and obligations. NIS2 is risk-based; DORA applies to defined financial entities and TLPT to selected entities; GDPR Article 32 requires risk-appropriate security measures and effectiveness testing where appropriate. Some specific rules or standards can require penetration testing for particular in-scope entities or environments, so confirm the exact requirement that applies to you rather than adopting a universal annual rule.

Should retesting be included in the engagement?

Retesting is valuable because it checks whether a specific reported weakness was remediated as intended. Ask what counts as a retest, how many cycles or what time window is included, whether architectural changes create new scope, what evidence is produced, and how the final report distinguishes fixed, partially fixed, accepted, and still-open findings.

How should I compare penetration testing quotes?

Normalize the scope first. Make every bidder price the same assets, roles, environments, authentication level, testing window, manual effort expectations, reporting, workshop, retesting, on-site work, evidence retention, and data-handling requirements. Then compare technical depth, assigned people, safety controls, deliverables, and commercial assumptions, not only the headline price.

What is the difference between provider accreditation and tester certification?

Provider accreditation generally applies to an organization's processes or service capability under a specific scheme, while practitioner certifications apply to individual people. Both can be useful evidence, but they answer different questions. Verify the current accreditation in the official directory and confirm which certified people will actually work on your engagement.

Who provides pentest services for companies in the Baltics?

Within this guide, Secmentis publishes penetration testing pages for Lithuania, Latvia, and Estonia; CyberAudit publishes Lithuania and Estonia pages and names clients in Latvia; SolutionLab says it serves Baltic clients from Lithuania; and DeepStrike tests remotely across all three. Vilnius firms such as Hackdeflect, Baltic Amadeus, and Critical Security are the main Lithuania-based options. Confirm the contracting entity and tester locations for each country in scope.

What is penetration testing called in Lithuanian?

Lithuanian sources usually call it įsilaužimų testavimas (break-in testing) or skverbties testavimas, and many provider sites also use the English terms pentest and penetration testing. Search procurement notices and provider sites for all of them so you do not miss relevant offers.

Is a penetration test the same as the NIS2 cybersecurity audit in Lithuania?

No. The audit that in-scope entities must commission at least every three years follows NKSC's audit methodology and checks whether the required measures are in place. A penetration test is technical testing of defined systems. Its findings and retest results can serve as evidence in the audit, but a pentest report does not replace it.

Conclusion

The strongest penetration-testing shortlist for a Lithuanian organization is not the longest list of cybersecurity companies. It is the set of providers whose Lithuania relationship, technical scope, assigned people, testing depth, authorization controls, reporting, retesting, data handling, and commercial assumptions can be evidenced before the contract is signed.

DeepStrike appears first in this guide by disclosed publisher editorial placement, while Lithuania-established and remote alternatives are compared under the same evidence rules. Use the shortlist as a starting point, then make the final decision against your own architecture, assurance obligations, procurement constraints, and risk tolerance.

If DeepStrike is a technical fit, the next step is to discuss a properly authorized scope and request a proposal that makes the assets, test model, deliverables, data handling, and retesting terms explicit.
