About us
The Security Standard for AI Systems.
Casdo Labs GmbH has its registered office in Munich. We develop Patronus in Regensburg: security software that runs on the device, with openly published models.
Why We Exist
Enterprises are deploying AI across critical workflows but lack any systematic way to monitor, audit, or secure these interactions. Prompt injection attacks go undetected. Sensitive data leaks through model boundaries. Compliance with the EU AI Act becomes impossible without observability.
The more autonomously AI systems act, the closer security has to move to the user. Existing solutions are cloud-dependent and platform-specific. Patronus is different: a model-agnostic, device-local AI security layer. Security analysis runs locally and can operate without a cloud connection.
