A pen test is short for “penetration test,” which is a simulated cyberattack on a network, computer, or endpoint in order to test the security level. It’s a pre-approved hack that allows IT departments and security personnel to gather information about weaknesses or vulnerabilities in the network that could be ripe for a real cyber attack.
Basically, a pen test is like a fire drill for network security. It tests to see if everything performs as it should in case of an actual attack.
