A professional penetration test (pentest) is a targeted security review of IT systems in which vulnerabilities are identified and exploited – under controlled conditions. The goal is to simulate real attack vectors in order to objectively assess a company's IT security. The test is conducted by experienced security experts and is based on clearly defined objectives, methods, and legal frameworks. Upon completion, companies receive a detailed report outlining the identified vulnerabilities, their associated risks, and concrete recommendations for action. A professional pentest contributes significantly to identifying security gaps early and sustainably increasing the level of protection.
