Autessa vs Lakera Guard
An alternative to Lakera Guard for AI agents
Lakera Guard, now part of Check Point, is known for fast screening of prompts and responses: your app calls its API, gets a flagged result and decides what to do next. Autessa makes that decision for you, and goes further on what happens around the prompt: it proves who is asking, scores the voice on the line and caps what any one person can take.

Where Autessa wins
Why teams choose Autessa over Lakera Guard
A decision, not a flag to handle
Lakera Guard tells your app something was flagged. Autessa acts on it: it asks the person to verify, holds the tool call for an admin or blocks it, with no branching logic for you to write.
It proves who is on the line
Before a sensitive tool runs, the word of the day, a passphrase, an authenticator code or a phone approval stands in the way, and the answer never reaches the model.
Claude can run your security review
Through the Autessa MCP, Claude or your own agent can read alerts, pull the dashboard and run the attack simulator, so a weekly review of what the firewall caught is one request.
Change the firewall itself
Lakera policies tune detectors. With Autobot you can change the product: add a check that calls your case system, reshape the alerts page or route approvals to your own on-call rota.
Trying it
Evaluate on your own traffic, risk-free
- Turn the firewall on in Monitor. Nothing changes for your users.
- Run the attack simulator against your most sensitive agent or API policy.
- Read a week of alerts and the dashboard side by side with your current tool.
- Tune thresholds and rules, then switch to Enforce.
FAQ
Autessa and Lakera Guard
Is Autessa AI Agent Firewall an alternative to Lakera Guard?
Yes. Both screen for prompt injection and data leakage. Autessa also acts on the result, and adds verification, voice checks, a duress word and limits on sensitive records for AI agents.
Who owns Lakera now?
Lakera is part of Check Point, which announced the acquisition in September 2025. Its product pages now carry Check Point branding.
How far can I customize the firewall compared with Lakera policies?
Rules, exceptions and thresholds are settings. Beyond that, the firewall is an Autessa app you can change down to its code: ask Autobot to add a check, change a screen or reroute an approval, or have your developers edit it directly.
Can an AI assistant work with the firewall through MCP?
Yes. The Autessa MCP gives Claude, ChatGPT, Cursor or your own agents the same data and actions as the app, such as reading alerts, pulling dashboard numbers and running the simulator, within the access of whoever connected it.
Can I run Autessa alongside Lakera Guard?
Yes. Start Autessa in Monitor mode, which records what it would do without changing anything, and compare results on your own traffic before deciding.
Does Autessa work with agents not built on Autessa?
Yes, through the AI Application Firewall API, which inspects each phase of each turn of your own application.
