In 2022, over 25,000 vulnerabilities were detected in IT systems, and this number increased to almost 30,000 in 2023, highlighting the growing challenge in the field of cybersecurity. In this context, zero-day vulnerabilities, i.e. those for which no patches have yet been developed or are not widely known to the public, pose a particularly serious threat. Attacks that exploit these vulnerabilities can have devastating consequences because they give cybercriminals the opportunity to exploit software vulnerabilities before manufacturers or users detect and fix them. Vulnerability management is therefore not only about being a step ahead in detecting potential vulnerabilities, but also about safeguarding against the unknown.
