| Summary | Australian 'autonomous system of agents' for product security that covers code, secrets, API pentesting and exploit validation. It proves findings with reproducible evidence, scores them against the customer's assets, writes merge-ready fix PRs routed to code owners, and runs remediation campaigns through Jira and Slack until merge, with the customer keeping final merge approval. | Agent platform with security integrations, not a dedicated AppSec scanner: OpenHands' open-source Vulnerability Fixer runs Trivy scans or ingests Snyk, Veracode or Checkmarx reports, then has OpenHands agents write and test fixes and open GitHub PRs. |

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.
