Black-box testing

Assess the target like an external attacker with no credentials or source code.

When to use it

  • First discovery runs.
  • External attack surface review.
  • Public exposure checks.
  • Unauthenticated baseline scans.

Limitations

  • Authenticated areas may remain untested.
  • Business criticality may be unclear until users enrich discovered assets.
  • The agent may need credentials or context for deeper follow-up work.
