Claude Security and Ares solve different halves of the same problem. Claude Security reads your source code, flags likely vulnerabilities, and suggests patches your developers can review. It is a solid defensive tool for teams that own their codebase. Ares works from the other side. She attacks your running APIs, web apps, and mobile apps the way a real adversary would, with no source code required, and proves every finding with a working exploit. Claude Security tells you what might be wrong in the code. Ares shows you what an attacker can actually do in production.
