BestDefense.io
BestDefense
BestDefense runs continuous AI pentesting that validates real exploits on every deploy, writes the fix, and proves vulnerabilities are closed.
Key features
- Continuous Pentesting on Every Deploy: Vortex uses AI-driven attack techniques, testing auth flows, chaining vulnerabilities, and abusing business logic the way an attacker would.
- Proof-Based Validation: Every finding is confirmed with a real exploit attempt before reaching your team, so unexploitable issues aren't reported.
- Automated Patching & Verification: After fixes merge, the original exploit chain reruns on the patched build to confirm the issue is truly closed.
- Compliance Automation: Each closed loop generates timestamped proof automatically mapped to SOC 2, NIST 800-53, ISO 27001, PCI DSS, and CMMC.
Best for
- Continuous Security Validation: Pentesting every code deploy automatically instead of periodic manual audits.
- Audit Readiness: Maintaining always-current compliance evidence for SOC 2 or ISO 27001.
- Vulnerability Remediation: Automatically generating and verifying fixes for proven exploits.
- DevSecOps Integration: Shifting security testing left into the deployment pipeline.
