Lakera Guard is a runtime security product for applications built on large language models. It inspects the input and output of each model interaction and blocks threats such as prompt injection, jailbreaks, and sensitive-data leakage before they reach an end user, and it also governs what an AI agent is allowed to do.
The product is delivered as an API with very low added latency and requires no change to the customer's own model or prompts. It is aimed at security and platform teams that need to enforce policy on AI applications and agents in production.
