What Is Penetration Testing and Why It Matters in Hungary 2025

Penetration testing pentesting also known as ethical hacking simulates real cyberattacks to find vulnerabilities in systems, networks, and applications. In Hungary, pentesting has become essential in 2025 for several reasons:

Regulatory Pressure NIS2, GDPR, ISO 27001:

Cyber Threat Surge:

Compliance and Insurance Needs:

In short, in Hungary today you can’t just rely on automated scanners or basic audits. Manual, expert led testing is critical. Pentesting uncovers chained exploits and business impact risks that simple scans miss.

Leading pentesters here follow industry standards like OWASP and NIST e.g. NIST SP 800‑115 and use a mix of black box, gray box, and white box methods. They simulate advanced attack scenarios including social engineering, API attacks, cloud misconfigurations to reveal hidden vulnerabilities.

Leading Penetration Testing Companies in Hungary

Several firms stand out in Hungary’s cybersecurity market. They range from specialized Hungarian boutiques to regional players. Here we compare key contenders in no particular order and highlight DeepStrike’s strengths:

While the top players lead Hungary’s penetration testing landscape, several smaller but capable firms contribute valuable niche expertise and regional coverage:

Hungary’s penetration testing ecosystem blends boutique ethical hacking firms and specialized local providers with global consultancies. While multinational firms deliver scale and compliance breadth, Hungarian specialists lead in manual depth, responsiveness, and technical precision giving domestic organizations a strong advantage in maintaining continuous, context-aware cyber resilience.

Pentesting Services and Compliance Requirements

Pentest firms in Hungary typically offer these core services:

These services address common vulnerability classes. For example, providers check for unpatched servers, weak credentials, SQL injection, broken auth, SSRF/path traversal in APIs, and more. See OWASP guidance and common network vulnerabilities for details. Many firms highlight adherence to OWASP and CWE standards.

For instance, DeepStrike explicitly tests web apps against the OWASP Top 10 and CWE Top 25, and uses NIST/SP800‑115 methodologies.

Compliance Focus: NIS2, GDPR & ISO 27001

Hungary’s 2025 cybersecurity law Act LXIX/2024 requires appropriate measures including vulnerability testing for entities in critical sectors. It aligns with GDPR’s Article 32, which mandates technical security measures like regular pentesting to protect personal data.

In practice, regulators expect pentest reports to serve as evidence of compliance: for example, PCI DSS 11.3 and ISO 27001 also call for periodic penetration tests.

DeepStrike and peers often emphasize these frameworks. DeepStrike’s own site notes compliance with OWASP, NIST, and PCI standards. Their teams hold certifications OSCP, CREST, GIAC to match best practices.

When you hire a Hungarian pentest firm, verify they know NIS2 obligations and GDPR requirements for instance, their report should document fixes for appropriate technical measures under GDPR.

The KRÉTA Incident

To illustrate why pentesting is crucial, recall Hungary’s KRÉTA school system hack 2015. Attackers exploited a known vulnerability to leak student data and ransomware payments. This breach affected thousands of schools, highlighting that even government run apps can have serious flaws.

Regular pentesting of critical applications could catch such issues beforehand. Local news and security blogs covered KRÉTA’s breach. Though that incident predates NIS2, it underscores the importance of ongoing security assessments.

How to Choose the Right Pentest Partner

Checklist for Hungarian buyers covering scope, retesting, credentials, compliance mapping, SLAs, and integrations

Picking a reputable penetration testing company in Hungary requires scrutiny. Here are key factors:

Experience & Certifications:

FAQs

Aside from DeepStrike, our global PTaaS leader, top Hungarian pentesters include Hacktify Budapest; network/web focus, Cyberintelsys Budapest; full spectrum VAPT, White Hat IT Security Labs app and code audits and Silent Signal Budapest; broad technical pentesting. 

Each has its niche. See our Top Penetration Testing Companies comparison for details.

Costs vary by scope. A simple small company pentest e.g. one website might cost a few thousand euros, while large enterprise tests multi app, networks, cloud can be tens of thousands or more.

PTaaS subscriptions run monthly. Factors include target complexity, number of assets, and compliance requirements. Remember, quality pentests pay off by preventing expensive breaches.

Web pentests examine a web app’s security. Testers will probe for SQL injection, cross site scripting XSS, broken auth/IDOR, CSRF, SSRF, and other OWASP Top 10 flaws. They may also test APIs/GraphQL endpoints and business logic. 

Reports include exploited examples and fixes. For a general definition, see our web application penetration testing services page.

A vulnerability scan is automated and finds known issues. Penetration testing is manual and goes deeper: testers exploit vulnerabilities to demonstrate risk. It can chain exploits e.g., XSS session hijack data exfiltration to show real impact. 

Think of pentesting as the ethical hacker’s simulated attack that goes beyond what tools alone can do. See our comparison in vulnerability assessment vs penetration testing.

Neither law explicitly says do pen testing, but they require adequate security controls and regular reviews. GDPR Article 32 calls for appropriate technical measures which industry experts interpret as including pentests. 

Hungary’s NIS2 law Act LXIX/2024 mandates vulnerability testing at least every two years. In practice, pentesting is the best way to prove compliance with these standards.

PTaaS is a subscription model where pentesting is ongoing rather than one off. It typically includes a platform with live dashboards, continuous testing, and retests after fixes. PTaaS is ideal for DevOps environments that change often. 

DeepStrike pioneered this in Hungary, offering a continuous penetration testing platform alongside manual reviews. PTaaS means you get security feedback year round, not just annually.

Pentesting is a red team activity attack simulation. A red team offense tests your defenses; a blue team defends. In some engagements, red and blue teams work together to improve security. 

For more, see red team vs blue team explained. Essentially, pentesting is one form of red teaming, focusing on technical vulnerabilities. A full red team exercise might also include physical and social attacks, but both are proactive security measures.
