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:
- Hungary has adopted the EU’s NIS2 Directive via Act LXIX/2024 effective Jan 2025, which mandates regular risk assessments and vulnerability testing for critical infrastructure and digital service providers.
- Similarly, GDPR’s Article 32 requires appropriate technical and organizational measures to protect personal data, which industry experts interpret as periodic security testing. Pentesting helps demonstrate compliance with NIS2, GDPR, PCI DSS 11.3, ISO 27001, and local cybersecurity rules by validating that controls actually work.
Cyber Threat Surge:
- In 2024-2025 Hungary saw a spike in ransomware and data theft incidents. For example, Reuters reported a hack on Hungary’s Defence Procurement Agency by an INC ransomware group in late 2024.
- Manufacturing, fintech, and logistics sectors have reported repeated downtime due to cyberattacks, with phishing and remote access exploits leading the threats. These real world breaches show that even government agencies can be targeted highlighting why businesses must test their defenses.
- Indeed, recent analyses find that 73% of data breaches exploit web application flaws, so thorough web pentests are crucial.
Compliance and Insurance Needs:
- Organizations in finance, healthcare, energy and other regulated industries in Hungary require annual pentesting. Compliance benchmarks like NIS2 and ISO 27001 explicitly call for periodic tests of infrastructure and applications.
- Many Hungarian companies also need pentesting to qualify for cyber insurance. In fact, roughly 75% of InfoSec teams globally conduct pentests for regulatory reasons and this trend is mirrored in Europe.
- Proactively finding and fixing holes not only avoids breaches IBM’s cost of breach is $4.4M but also strengthens customer trust and insurance coverage.
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.

Pentesting Services and Compliance Requirements
Pentest firms in Hungary typically offer these core services:
- Web Application Pentesting: Testing websites, web apps, and APIs OWASP Top 10, SQLi, XSS, CSRF, IDOR, etc.. Almost 73% of breaches involve web flaws, so this is a must.
- Mobile App Pentesting: Security testing for iOS and Android apps. Many companies, banks, e-commerce, and public services use mobile apps and must secure them. DeepStrike and others provide dedicated mobile app penetration testing solution covering both client and server sides.
- Network Infrastructure Testing: External internet facing and internal network pentests. Firms map networks, test routers/firewalls, wireless, VPN/RDP, and Active Directory setups. See internal vs external pentesting differences in our difference between internal and external penetration tests guide.
- Cloud and DevOps Security: Review AWS, Azure, GCP configurations and CI/CD pipelines. Many Hungarian firms are on cloud, so pentesters test cloud instances, APIs, and misconfigurations.
- Red Teaming & Phishing: Simulated full scale attacks, including social engineering phishing emails, baiting and adversary emulation. Silent Signal, DeepStrike, and others conduct phishing campaigns and red team drills to test people and processes.
- Specialized Tests: IoT/Wi Fi testing, OT/ICS industrial pentesting, Active Directory audits, API/GraphQL testing, etc., as needed.
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
Picking a reputable penetration testing company in Hungary requires scrutiny. Here are key factors:
Experience & Certifications:
- Ask about real world testing experience. Do their testers hold OSCP, OSWE, CEH, CREST, GIAC or similar certifications? Have they tackled environments like yours e.g. Windows/Active Directory, AWS cloud, custom apps?
- A strong track record in your industry finance, healthcare, etc. is a plus. One guide recommends expecting OSCP/OSWE/CREST to ensure quality.
Scope of Services:
- Match their offerings to your needs. If you need web security, ensure they have dedicated web application penetration testing services. For mobile apps, ask for a mobile app penetration testing solution covering both platforms.
- Check that network pentests include both external and internal scans, see differences between internal and external penetration tests and that cloud assets are included if relevant. Some providers also do IoT, API, and DevOps testing.
Methodology:
- A good pentester explains their process. They should use recognized standards OWASP Web Testing Guide, PTES, or NIST SP 800‑115. Ask whether they do black box no info, gray box some info, or white box full source testing, and why.
- See our black box vs white box testing explained guide. The approach should fit your environment. For example, if you want to see real attacker results, insist on black or gray box tests.
Reporting & Remediation:
- Review example reports. Expect detailed findings with CVSS severity scores, exploit write ups, screenshots, and clear remediation steps. Ensure they include a retest phase to confirm fixes.
- Check that reports address compliance: for instance, they should cite relevant NIS2/GDPR/PCI standards and provide evidence for auditors.
Continuous Testing PTaaS:
- Consider if you need ongoing security. Traditional one off tests help, but modern threats evolve fast.
- Providers like DeepStrike offer Penetration Testing as a Service PTaaS or a continuous penetration testing platform, monitoring your assets year round. This is ideal for DevOps shops or highly dynamic environments.
Pricing and Value:
- Compare pricing models. Costs vary widely by scope: a basic web pentest can be a few thousand euros, while a full enterprise test networks, apps, and cloud runs higher. Beware of the cheapest scan only quotes; a true pentest requires skilled labor. Instead, view pentesting as an investment: avoiding even one breach can save millions.
- The IBM report puts the average breach cost at $4.4M. For ballpark figures, see our guide on penetration testing cost.
Local Presence & Language:
- While many firms operate regionally, working with Hungarian based testers can ease communication and understanding of local laws.
- Providers in Budapest or with local offices can be helpful for on site visits or Hungarian language reporting.
A handy checklist is our penetration testing RFP writing guide, which covers all the above points when you request proposals. Remember: penetration testing isn’t a one time checkbox.

- What are the top penetration testing companies in Hungary?
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.
- How much does penetration testing cost in Hungary?
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.
- What is included in a web application penetration test?
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.
- What is the difference between penetration testing and a vulnerability scan?
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.
- Does GDPR or NIS2 require 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.
- What is PTaaS Penetration Testing as a Service?
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.
- How do the red team and blue team relate to pentesting?
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.
