The organization known for developing the Pen Testing Execution Standard (PTES) is PTES itself. This standard was created to provide a cohesive framework for penetration testing, outlining best practices and a comprehensive approach to conducting security assessments.

PTES includes detailed components like pre-engagement interactions, intelligence gathering, threat modeling, and post-engagement clean-up, which are all essential aspects of a penetration test. Organizations that adhere to PTES benefit from a structured approach, enabling them to meet various compliance and security requirements more effectively.
