The text discusses penetration testing, a foundational security practice that involves evaluating a system's vulnerabilities and weaknesses through simulated attacks. The concept of vendor rotation in penetration testing has been around since the 1960s, where organizations would rotate their pen test vendors every couple of years to ensure new eyes and perspectives were dedicated to testing efforts. However, this process has become increasingly time-consuming and costly for security teams, with significant human resource costs involved. A new approach, known as on-demand pentester rotation, offers flexibility and cost savings by providing an evergreen, elastic bench of talent that can be rotated whenever needed, without the need for vendor evaluation processes or additional GRC reviews. This approach allows organizations to dictate their security engagement needs, from penetration tests to bug bounty programs and attack surface discovery, with access to thousands of security professionals and enthusiasts through the Bugcrowd Platform.
