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.
