Information Systems Security Assessment Framework (ISSAF)

ISSAF is not very active, but the guide it has provided is quite comprehensive. It aims to evaluate the information security policy and process of an organization with regard to its compliance with IT industry standards, along with laws and regulatory requirements. The current version of ISSAF is 0.2.

The stages that it covers can be found at https://www.owasp.org/index.php/Penetration_testing_methodologies.
