Defense-in-depth security for on-device AI.

A security SDK that protects on-device AI agents from prompt injection, unauthorized actions, data leakage, and model theft.

A guardrail for on-device AI.

A small SDK that sits between the user, the model, and any action the AI takes. Four runtime checks, all on-device, no network dependency.

  • InputGuard
    Detects prompt injection before it reaches the model.
  • ToolGuard
    Enforces policy on AI-initiated actions: tool calls, transfers, messaging, data sharing.
  • OutputGuard
    Filters sensitive data and detects when the model has been manipulated.
  • ModelGuard
    Protects model weights from extraction and theft.
