Secure AI agents

How to secure your AI agents

Autonomous agents fail in a handful of predictable ways. Here is each failure mode, and the control that contains it, whatever framework you use.

Start free5-minute quickstart

Whether you build on LangChain, CrewAI, AutoGPT, OpenAI's tools, or MCP, autonomous agents share the same risks: uncontrolled egress, exposed credentials, data exfiltration, runaway swarms, and no trustworthy record. RIL Warden addresses each one from the action path, so it works regardless of framework.

The failure modes and their fixes

1. Uncontrolled egress

An agent connects anywhere. Fix: default-deny allowlist per agent. See the agent firewall.

2. Exposed API keys

Secrets end up in prompts or logs. Fix: server-side key injection the agent never sees.

3. Data exfiltration

Data leaves through a tool or injection. Fix: blocked exfil/C2 channels, decoys, auto-jail. See stopping exfiltration.

4. Prompt injection

The agent is tricked. Fix: contain what a tricked agent can do. See prompt injection protection.

5. No trustworthy log

You cannot prove what happened. Fix: a signed, on-chain-checkpointed flight recorder. See the audit log.

One gateway, any framework

Route your agents' traffic through Warden with the Python or Node SDK, the MCP server, proxy mode, or raw HTTP, and lock down a Kubernetes namespace so agents can only egress through it. Start with the 5-minute quickstart or the deeper guide.

Frequently asked questions

How do I secure a LangChain / CrewAI / AutoGPT agent?
Route the agent's web and tool calls through a policy gateway that enforces default-deny egress, hides secrets, blocks exfiltration, and logs everything. RIL Warden does this with SDKs, MCP, or proxy mode, independent of the framework.
What is the biggest risk with autonomous agents?
Uncontained action: an agent with tools and network access can reach the wrong place, leak secrets, or exfiltrate data - especially after a prompt injection. The fix is containment at the action layer.
Do I need to change my agent code?
Often very little. You can use proxy mode or the MCP server with almost no code change, or the SDK for tighter control.
Is there a free way to start?
Yes. Warden's free tier covers 3 agents and 25,000 gateway requests a month with the full signed history.
