This content explains why security validation should focus on real-world resilience rather than checklist-based compliance. It compares penetration testing, red teaming, and purple teaming to help organizations choose the right approach. Penetration testing is a targeted, authorized assessment designed to identify and exploit technical vulnerabilities such as missing patches, misconfigurations, or access issues within a defined scope.
