Penetration testing is a proactive, authorized check of an IT system’s security by safely trying to exploit weak spots—like OS and app bugs, misconfigurations or risky user actions. It also proves that defense tools work and that users follow security rules.
More than just finding flaws, pentesting shows how chains of small issues can let an attacker in. Even a minor bug can combine with others to create a real threat. This helps a business see its true risks.
Pentests point out which vulnerabilities matter most, so you can spend your security budget where it’ll make the biggest difference. And because new weaknesses pop up and systems change, you need regular tests. That way, penetration testing stays a key part of your security plan—keeping data safe, meeting rules, and protecting your IT environment.
