Selection criteria

  • Self-hosted deployment path
  • Operational clarity
  • Rule and policy control
  • Rollback planning

Who this helps

Teams that want local control over traffic inspection instead of a fully managed edge service.

1

Packaged self-hosted WAF

SafeLine

Useful when teams want a deployable WAF product rather than only a WAF engine.

2

Integrated web server security stack

BunkerWeb

Relevant where web serving and WAF-like controls should live close together.

3

Open-source WAF engine

ModSecurity

A classic option for teams prepared to manage connectors, rules, and tuning.

4

Embeddable WAF engine

Coraza

Strong fit when a team wants to integrate WAF behavior into Go-native or custom gateways.

Ranking note

Shortlists are not universal rankings.

The shortlist favors local traffic control and inspectable operations. Teams should rank candidates again using their own automation, staffing, observability, backup, and emergency bypass maturity.
