PT0-003 is the current exam code for CompTIA PenTest+, version 3. "PT0" denotes the PenTest+ series and "003" the V3 revision. It validates penetration-testing and vulnerability-assessment skills, including planning, scoping, exploitation, and reporting.
What it means
PenTest+ is CompTIA's penetration-testing credential; PT0-003 is its active (V3) exam. CompTIA's official page describes it as an intermediate offensive-security certification covering engagement planning, information gathering, attacks and exploits, and reporting — assuming a solid security foundation beforehand.
