Lakera Guard
Definition
Real-time API for detecting and blocking prompt injection attacks, PII leakage, and toxic content. Protects the input surface — stopping malicious prompts before they reach the model. Does not govern execution — clean inputs can still produce harmful tool calls.
Why It Matters
Prompt injection defense is essential but not sufficient. A perfectly clean, non-injected prompt can still generate a destructive tool call if the model halluccinates or misinterprets intent. Input safety ≠ output safety ≠ execution safety. Each layer protects a different surface.
How Exogram Addresses This
Use Lakera for input protection (prompt injection, PII, toxicity). Use Exogram for execution governance (action validation). Lakera stops malicious inputs. Exogram stops malicious actions — regardless of input quality. Both are needed for defense in depth.
