Continuous offensive security (COS) combines DAST, AI penetration testing, and AI red teaming to provide recurring vulnerability discovery and validation as applications change. Unlike point-in-time assessments, COS coordinates testing methods on different schedules tied to releases, architectural changes, or emerging risks. AI penetration testing adapts based on application responses, validates exploitability, and can investigate business logic flaws and chained attacks — going beyond fixed scanner checks. AI red teaming specifically targets risks in agentic AI systems, including prompt injection, tool abuse, and data exfiltration. Human oversight remains important for scoping, authorization, and risk decisions. Snyk's Evo platform integrates these capabilities, using prior scan findings to focus AI pentesting on novel flaws and applying independent exploitability validation before surfacing findings.
