Step 2 of 5
Authentication boundary analysis
We examine how the application authenticates users — password reset, session management, OAuth callback, JWT handling. Authentication-boundary errors are the single largest source of critical-class findings in our engagement portfolio.
What we look for
every entry, recovery, and elevation path an authenticated user touches.
What we find
token-replay surfaces, session-fixation gaps, OAuth-callback assumptions that don’t survive contact with an adversary.
What we conclude
the boundary either holds under pressure or it doesn’t. We document both outcomes the same way.
