Full WSTG-aligned web application pentest — 12-phase methodology from information gathering through reporting, with concrete commands, expected outputs, pitfalls, and verification per phase.
Attack SAML SSO via XSW, signature strip, metadata extract.
Use when two or more verified findings may combine into a higher-impact authorized attack path.

Use scoped Nmap discovery to identify services adjacent to web applications, including databases, remote administration, mail, caches, and non-standard API ports. An open port is an observation; service identity and unauthorized access require separate validation.
