| Summary | San Francisco application-security platform whose autonomous AI agents trace business logic and data flows to find exploitable code vulnerabilities, check dependency reachability and secrets, review pull requests with proposed fixes, and run agentic pentests against running applications, re-running each attack after a fix merges to confirm it is closed. | GitHub Copilot’s coding agent. Listed here only for the official workflow that assigns Dependabot security alerts to Copilot (or other agents) to open a draft fix PR. |

Listings tagged agent platform with security integrations are coding platforms with a documented scanner or vulnerability-fix workflow, not dedicated application-security products. Dedicated AppSec listings are compared on the AI code security agents table.
Side-by-side data is generated from the open dataset. “Vendor-claimed” frameworks are as marketed by each vendor and not verified by Agent Index; framework tags indicate relevance, not certification. Request current quotes from each vendor before buying. This page does not rank or score vendors. Sponsored comparisons, if any, will be labelled.
