Best fitTeams wanting a simpler WAF evaluation pathTeams with CRS experience or legacy deploymentsThe best choice depends on internal WAF operations maturity.

How to validate this choice

  • Deploy each option in the same traffic path where possible.
  • Replay representative clean and malicious requests.
  • Track blocked requests, false positives, latency, and operational effort.
  • Compare rollback steps and logging integrations before production use.

Scientific comparison rule

A WAF comparison is only meaningful when traffic path, rule mode, test payloads, and observation window are consistent. WAFWiki uses this principle to guide future benchmark pages.
