AI Agent Runtime Firewall

AI Agent Runtime Firewall

Block unsafe AI agent actions before they execute. Signed receipts included.

Aletheia Core audits high-risk AI agent decisions before agents read secrets, run shell commands, modify configs, send data externally, or touch production workflows. Every verdict can generate a tamper-evident receipt.

Watch the attack. Watch the agent. Watch Aletheia stop it. Verify the receipt. Protect your own system.

Step 1

First, watch the attack.

Prompt injection is not just bad text. Once an AI agent has tools, a malicious prompt can become a shell command, config change, leaked secret, or unauthorized action.

This is the failure mode Aletheia was built to stop.

Step 2

See it in action.

This is the live product demo — real enforcement decisions, signed audit receipts, and semantic threat detection running against actual injection attempts. The Protected Agent demo (Aletheia Trader) is coming next.

Step 4

Every decision gets a receipt.

Verify the hash. Detect tampering. Prove what happened.

Every ALLOW, REVIEW, or BLOCK decision can create a signed receipt.

Use receipts as portable evidence when you need to prove what the system saw, why it blocked an action, and which policy hash was applied.
