What Is Agentic AppSec?

Agentic AppSec (agentic application security) is the practice of using a team of AI security agents to run an organization's entire application security program: understanding the application, modeling its threats, finding the vulnerabilities that matter, deciding what is worth fixing, generating and validating fixes, and proving those fixes hold. It applies continuously to both new code and the existing backlog. The term is easy to confuse with agentic AI security, but the two point in opposite directions: agentic AI security protects AI agents from attack, while Agentic AppSec puts AI agents to work on security. The move toward agents running the program is a response to volume, because software now arrives faster than a human-run security program can clear it. Why does application security need a new operating model? Application security needs a new operating model because the rate at which code is written has changed, and a program sized for the old rate cannot absorb the new one. A traditional program finds issues and hands them to people. Those people then own everything downstream of the finding: triage, prioritization, the…
