Best for: Developers building AI agents that need real email addresses and file storage integrations.
- 08
Superagent
Superagent is an autonomous security factory for applications and repositories, combining PR security scans, dependency updates, red-team reports, runtime guardrails, and MCP/API access so agents can retrieve findings and return remediation reports.
Best for: Engineering teams that want agent-driven security loops tied to GitHub repositories and CI rather than manual checklist reviews alone.
- 09
Pervaziv AI
Pervaziv AI offers Cortex, a secure AI coding and DevSecOps suite for multi-cloud application development, deployment, and runtime protection. The platform combines coding agents, developer tooling plugins, and AI security reviews with tiered per-user subscriptions.
