Intent
Users evaluating Coraza WAF as an embeddable engine or reverse proxy integration.

Prerequisites

  • Comfort reading Go or proxy configuration.
  • A representative upstream application.
  • A clear decision between embeddable engine and proxy integration.
  • A CRS test and tuning plan.

Deployment workflow

Use a narrow, reversible rollout.

1

Decide the integration shape

Coraza is often evaluated as an engine rather than a packaged WAF product. Decide whether the test should use Caddy, a gateway, or custom Go integration.

  • Integration target is documented.
  • Ownership for ongoing tuning is assigned.
  • Rule source and update process are clear.
2

Load a small rule set first

Start with minimal rules or a controlled CRS profile before enabling broader inspection. This keeps early debugging manageable.

  • Rule loading is visible in logs.
  • Clean traffic passes.
  • Rule hits map to specific request fields.
3

Compare with packaged WAF alternatives

Coraza may be a strong engine choice, but teams should compare integration effort against packaged products like SafeLine or managed WAFs.

  • Engineering effort is estimated.
  • Deployment ownership is clear.
  • Observability and rollback are designed.

Validation checklist

  • Confirm the gateway sees request bodies and headers needed by rules.
  • Replay clean and malicious lab requests through the same route.
  • Check rule performance under expected request sizes.
  • Document how rules are updated and reviewed.

Rollback planning

  • Keep a bypass route around the gateway change.
  • Pin rule versions during tests.
  • Separate WAF policy changes from unrelated gateway releases.

Common mistakes

  • Treating an engine evaluation like a turnkey product deployment.
  • Skipping rule update and ownership planning.
  • Testing only standalone payloads instead of real application requests.

FAQ

Is this Coraza WAF Evaluation with Caddy or Go Gateways official documentation?

No. WAFWiki is independent. Always verify commands, pricing, and support terms with the linked official documentation before production use.

Should I enable blocking immediately?

No. Start with a lab route or observation mode where possible, collect clean traffic, tune false positives, and document rollback first.
