Out of scope 3

Don't test these. A program can exclude a host another program covers; the program you report to decides.

  • Denial of Service vulnerability (i.e. overwhelming our services with a high volume of requests)

  • Reports indicating that our services do not fully align with "best practice" (e.g. missing security headers or suboptimal email-related configurations such as SPF, DMARC etc.)

  • TLS configuration specifics (e.g. no support for TLSv1.3, a specific cipher suite configuration, etc.)
