    This does not work against F5 ASM despite the claims in the review article here:

      Worked on an earlier version maybe?

      The tool wasn’t changed for a year and according to article it has only one XSS payload related to F5 ASM. Probably, it was just mitigated with additional rules and guess the same applies to the rest of vendor-specific payloads.
