This profile is written for evaluation rather than promotion. Use it to understand where open-appsec fits, which assumptions need validation, and which alternatives deserve side-by-side testing.
Evaluation checklist
- Map the intended Kubernetes, NGINX, or API gateway insertion point before comparing controls.
- Validate how policies, learning behavior, and logs fit the existing cloud-native workflow.
- Test API-heavy routes and authentication flows separately from static web paths.
- Confirm open-source versus commercial feature boundaries for the deployment model.
