A penetration tester plays a critical role in cybersecurity by simulating attacks on systems, networks, and applications to identify vulnerabilities before malicious actors can exploit them. Through a series of ethical hacking techniques, they assess the effectiveness of security measures and provide detailed reports outlining the findings and suggested remediations. This proactive approach helps organizations strengthen their security posture, comply with regulations, and enhance their overall cybersecurity strategies. The ultimate goal of a penetration tester is to improve an organization's resilience against potential cyber threats and safeguard sensitive information.
