What is Penetration Testing?

Penetration testing pentesting is a hands on security assessment where experts simulate cyberattacks to find and exploit vulnerabilities in systems.

Testers mimic hacker techniques on web apps, networks, or cloud environments to reveal weak spots SQL injection, misconfigurations, weak passwords, etc. before real attackers can.

A pentest goes beyond automated scanning by using manual methods and creativity. In other words, it’s like staging a fire drill for your security, you test if an attacker could break in, then fix problems before the bad guys arrive.

Why Penetration Testing Matters in 2025

Cyberattacks are growing in scale and sophistication. The global pentesting market is projected to nearly double by 2029 as organizations scramble to bolster defenses. In Europe, new regulations make regular pentesting mandatory for many sectors.

The EU’s NIS2 Directive explicitly calls for periodic independent penetration tests on critical systems. For example, banks and healthcare providers must test annually or after major changes.

In 2025’s landscape of AI powered exploits and advanced ransomware, skipping tests is risky. Penetration tests help prevent costly breaches IBM reports the average data breach now costs $4.4M by finding problems early.

They also validate compliance, standards like PCI DSS, HIPAA and GDPR expect you to hack proof your defenses. In short, pentesting turns uncertainty into actionable insight by showing exactly where attackers could strike.

Comparison of Leading Lithuania Pentest Firms

How to Choose a Penetration Testing Provider in Lithuania

Choosing the right vendor is crucial. Follow these steps:

1. Define Your Scope & Goals. Decide what assets to test web apps, cloud, network, etc. and why compliance, risk reduction, etc.. Clear scope helps you pick specialists e.g. a cloud savvy team vs. a hardware/OT expert.
2. Check Expertise & Certifications. Look for certified testers OSCP, CISSP, CEH and accredited firms CREST membership, ISO 27001. Providers with experience in your industry or regulatory requirements GDPR, DORA, NIS2 are a plus.
3. Assess Methodology. Ask if they perform black‑box, white‑box, or grey‑box testing and whether they include social engineering phishing or physical tests. Ensure they follow recognized frameworks NIST SP800 115, OWASP, OSSTMM and deliver a clear process.
4. Review Reports & Support. A good pentest report should prioritize findings by risk and give actionable fixes. Ask for a sample report if possible. Check if they offer re testing after fixes many top firms include at least one free retest.
5. Compare Pricing vs. Value. Don’t just pick the cheapest. Balance cost against depth of testing. Lithuanian pentesters range from €1K for small projects to large multi test contracts. Consider PTaaS subscriptions which spread cost and provide continuous coverage versus one off audits.
6. Evaluate Communication. Responsiveness and clarity matter. Do they provide dashboards or status updates? Some like DeepStrike integrate with Slack/Jira for live feedback. Ensure they can work with your team effectively.

Common Pitfalls & Myths

• Myth: One pentest lasts forever. Reality: New vulnerabilities emerge all the time. Annual or continuous testing is recommended. The NIS2 directive effectively requires at least yearly tests for critical systems.
• Myth: Automated scans catch everything. Reality: Scanners miss logic flaws and chained exploits. Manual testing is essential to uncover issues that tools overlook.
• Mistake: Choosing the lowest bid. Reality: A very cheap test might be superficial. Check the firm’s track record and methodologies. Worth spending more to avoid a false sense of security.
• Mistake: Testing only the network. Reality: Modern attacks often target web apps and human factors. Make sure your scope covers both technical and social tests e.g. phishing.

Choosing the right penetration testing partner in Lithuania can greatly improve your security posture. Each highlighted firm brings unique strengths:

• DeepStrike for its agile PTaaS platform and global reach.
• HackDeflect for deep compliance and red teaming expertise.
• ENNEID for startup friendly value and responsiveness.
• Baltic Amadeus for enterprise scale coverage and ISO certified processes.
• Critical Security for veteran, deep dive tests.
• SolutionLab for accredited, insurance backed service.
• BlueBridge for MSP integrated convenience.

Use this comparison to match your needs, consider scope, budget, and industry requirements. With cyberthreats on the rise, the right pentest provider will uncover hidden risks before attackers do and help you fix them quickly.

  • Samples and templates can vary, but key elements are: executive summary, findings list, risk remediation steps, and proof of concept.
  • See example penetration testing report PDF for reference.

• What is the difference between internal and external penetration tests?
  • An external pentest simulates an attack from outside your network targeting internet facing assets websites, VPNs, email servers, cloud services.
  • An internal pentest assumes the attacker is already inside like a compromised employee or network. It tests lateral movement and insider exploits.
  • Both are important: external tests check perimeter defenses, while internal tests reveal what an attacker can do once inside.

• Why consider Penetration Testing as a Service PTaaS?
  • PTaaS provides continuous testing instead of one off audits. It typically includes ongoing scanning, retesting, and real time reporting. This model keeps pace with agile development and cloud changes.
