Phishing detection

Turn on phishing detection by pointing Metis Suite at a phishing detection backend.

Phishing detection checks messages for phishing and shows the verdict as a badge. People can also ask the assistant to check a message. It is off on a new instance. It needs a separate phishing detection backend running where your instance can reach it.

Turn it on

1. Open Dashboard, System, Phishing detection under Drivers.
2. Set Driver to metis.
3. Enter the Backend URL: the address of your phishing detection backend.
4. Click Save changes and enter your authenticator code.
5. In the Health card, click Run check. It calls the backend’s /health endpoint.

To set the starting value before the first start, use:

METIS_PHISHING_DETECTION_DRIVER=metis
BACKEND_URL=https://phishing.example.com

What it sends

Metis Suite sends the raw message to the backend for a verdict. Run the backend somewhere you trust with your users’ mail.

Turn it off

Set Driver to disabled and save. While it is off, the phishing badge, the assistant’s phishing tool and the matching MCP tool are hidden.
