The Cerberus Protocol

Secure, contain, and protect every agent action.

Cerberus is Aleytheya's runtime control layer. It sits between your AI agents, tools, and LLM providers; checks every request and response; blocks unsafe actions when policy requires it; and builds the evidence trail your compliance team needs. No SDK changes, no agent rewrite, and works with every major LLM provider.

Core principle

Passive until risk appears. Active when it matters.

Cerberus begins by observing agent behaviour in real time, building context without interfering with operations. The moment material risk is identified, it activates the appropriate corrective controls based on severity, confidence, and policy. Start with industry-grade templates and configure your own runtime governance framework completely hassle-free.

Secure

Block adversarial inputs before they reach the model

The inbound enforcement layer. Prompt injection detection, PII scanning, DLP, budget caps, and runaway detection stop risky requests before they reach the model.

Contain

Guard what the model produces before it reaches users

The outbound enforcement layer. Destructive action blocking, category flagging, uncertainty detection, and PII scanning keep model outputs and tool calls inside approved boundaries.

Build the tamper-proof record that regulators require

The compliance and audit layer. Merkle-chained event logs, transparency records, data residency controls, and compliance reports create proof your auditors can review.
