4.1Not listed
vs VicariusSame
Remediation agent that ships production-ready fixes for open source vulnerabilities.

- Automatic remediation of scanner findings
- Fixes delivered into the developer workflow
- Works from existing security tooling

- Exploit and vulnerability intelligence with early CVE access
- In-house proof-of-concepts, packet captures and Suricata signatures
- Canary intelligence from internet sensors
