- Every bug comes with a reproducible failing test that proves it
- Finds runtime vulnerabilities by firing real exploits against the sandbox
- Tests untested integrations and hard-to-mock async services
- Free for open source projects
| - Publishes its own listening studies on the same platform with the same methodology as customer studies
