Your AI Agents Hold the Keys
to Your Kingdom

Today, every AI agent gets your raw API keys and secrets. One prompt injection, one compromised agent and your credentials are in the hands of attackers.

Click a threat to see how Heimdall defeats it

Exposed Raw Tokens

AI agents receive your actual API keys in plaintext. A single leak means attackers get full, unrestricted access to your services.

Token Placeholder Proxy

Agents only see safe aliases. Heimdall's proxy swaps them for real credentials at request time the actual secret is never exposed.

Secret Exfiltration

Prompt injection attacks can trick agents into sending your real secrets to attacker-controlled servers and you would never know.

URL-Locked Tokens

Each token is bound to its intended destination. An agent trying to send credentials anywhere unauthorized is instantly blocked.

No Usage Boundaries

Nothing stops an agent from sending your keys to a random third-party URL, or making thousands of calls you never authorized.

Rate Limits & Controls

Set per-token rate limits, daily caps, and budget thresholds. No agent can exceed the boundaries you define.

Zero Visibility

No logs, no rate limits, no audit trail. You have no idea which agent used which token, how many times, or where it was sent.

Full Monitoring & Audit

See exactly which agent used which token, how many times, and to what URL. Real-time dashboards and alerts for every action.

Your Agents Never Touch
a Real Secret

Instead of handing raw API keys to AI agents, Heimdall gives them placeholders. Use openai_token in your code our proxy injects the real credential at request time. The secret never leaves the vault.

Token Placeholder Proxy

Agents and developers use readable aliases like openai_token or stripe_key. Heimdall swaps them for real credentials at the proxy layer no one ever sees the actual secret.

URL-Locked Tokens

Restrict each token to its intended destination. openai_token only works for api.openai.com any attempt to send it elsewhere is instantly blocked.

Rate Limits & Usage Controls

Set per-token rate limits, daily caps, and budget thresholds. Prevent runaway agents from burning through your API credits or making unauthorized bulk requests.

Full Monitoring & Audit Trail

See exactly which agent used which token, how many times, and to what URL. Real-time dashboards and alerts for every suspicious pattern.
