Workflow model

Read the comparison through a traffic-flow diagram.

Read this as origin-side ownership versus managed edge enforcement. DNS control, client IP handling, global routing, origin exposure, logs, and outage bypass are first-order differences.

The two models differ less by the word WAF and more by who controls routing, policy, upgrades, logging, and emergency rollback.

How to validate this choice

  • Test SafeLine and Cloudflare WAF behind the same staging hostname or protected route when the architecture allows it.
  • Compare SafeLine's Docker / Linux path with Cloudflare WAF's Cloud edge / DNS proxy path before comparing feature lists.
  • Replay clean login, upload, API, and admin workflows before using blocking actions.
  • Record rule matches, false positives, latency, logging detail, ownership, and rollback steps for both options.

Scientific comparison rule

Test the same application paths while recording who owns routing, policy, logs, upgrades, incident response, and rollback.
