Penetration testers source flaws and weaknesses in existing, active systems such as websites, data storage systems, and other IT assets. Penetration testing is often confused with vulnerability testing. In actuality, these are two distinct cybersecurity specializations. Vulnerability testers look for system flaws and weaknesses during a security program’s design and setup phases. While penetration testing and vulnerability testing are both critical, they have unique responses and strategies.
At a high level, pen testers help their clients avoid the loss of consumer confidence and public relations fallout that accompany network security hacks. They also help them implement sound digital security measures that fit within set budgetary constraints.
Many companies in the technology and information security sectors hire a large number of penetration testers—as do government and private-sector organizations.
