Your AI agent can do almost anything. Who decides what it's allowed to do?
That's the question keeping security teams up at night.
Claude Code, Cursor, Codex, OpenClaw — they're shipping code, querying databases, and clicking through real browsers. They act autonomously, at superhuman speed.
And right now, nothing sits between them and the systems they touch.
No layer decides what's allowed. No record of what happened. No way to cut off access without redeploying.
Then I found Kastra Labs.
Launched today on Product Hunt.
It's the runtime authorization layer for AI agents. It decides what agents can and cannot do before actions execute — enforcing policies with sub-1ms latency across tools, prompts, inputs, and outputs.
Here's what makes it different:
➟ Runtime authorization — every prompt, tool call, shell command, and API request is checked against policy before it runs. Deny in under a millisecond
➟ One control plane — govern agents and policies across Claude Code, Cursor, Codex, OpenClaw, Anthropic SDK, OpenAI SDK, and more
➟ Recon — scan your agent's history and see every risky thing it already did, with policies drafted for each one
➟ Audit trail — signed, append-only traces. Stream to your SIEM. Pass audits on the first pass
➟ Deployment flexibility — cloud, hybrid, self-hosted, or air-gapped. Same policies. Same evidence vault
What this actually means:
✓ Prevent unauthorized tool use, prompt injection, and data exposure before they become incidents
✓ Authorize actions, tools, shell commands, API calls, SQL queries, and web actions — all from one control plane
✓ Auto-detect risky behavior and draft policies before enforcing
✓ SOC 2, ISO 27001, HIPAA, GDPR compliant. FedRAMP ready
Trust the rules, not the agents. 142 active policies. 4,812 requests/second. p99 0.8ms latency.
Built for global banks, federal agencies, and frontier AI labs.
