What is penetration testing?

Penetration testing, or pen testing, is a security test that simulates a real attack on an organization’s systems, networks, or applications.

How does penetration testing work?

Authorized security professionals use the same techniques as attackers. They look for vulnerabilities and determine whether they can be exploited. They then document what they find and provide recommendations for addressing weaknesses.

Why is penetration testing important?

Penetration testing helps organizations understand which security weaknesses could be exploited, not just which vulnerabilities exist. As attacks become more sophisticated, testing defenses from an attacker’s perspective is critical for finding and fixing gaps before a real attacker exploits them.
