WAF comparison
ModSecurity vs Coraza
Compare ModSecurity and Coraza for OWASP CRS compatibility, rule tuning, Go-native environments, and WAF engine selection.
WAFWiki verdict
Choose ModSecurity when existing CRS operations and connector experience matter. Choose Coraza when Go-native integration and modern gateway ownership are stronger priorities.
Search intent: Engineer choosing an open-source WAF engine for CRS-based detection and custom gateway integration.
| Area | ModSecurity | Coraza | WAFWiki note |
|---|---|---|---|
| Engine lineage | Classic open-source WAF engine ecosystem | Modern Go-based WAF engine | Both are engine-oriented choices rather than managed WAF services. |
| Integration work | Depends on connector and reverse proxy setup | Depends on Go or gateway integration path | Compare the supported integration path, not only the rule language. |
| Best fit | Teams with ModSecurity or CRS operations history | Teams building Go-native or custom proxy paths | Operational ownership is the decisive factor. |
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.
ModSecurity
ModSecurity is a widely known open-source WAF engine and a common baseline for rule-based web application firewall deployments.
