Penetration testing

Discover real vulnerabilities + get fast fixes – penetration testing reveals actual weaknesses that can be quickly addressed.

Lower risk of attacks – strengthen your IT infrastructure and prevent costly damage by staying one step ahead of potential attackers.
Example: With an €800 investment, a large enterprise avoided a €40,000 security risk that was later actively targeted.

Increased trust and compliance – show clients and partners that your systems are secure and meet both local and international standards (e.g. GDPR, ISO 27001).
