Lakera

Lakera is an AI security platform that protects LLM applications and agents at runtime. Its API inspects inputs and outputs for prompt injection, data leakage, and policy violations, and governs what agents are allowed to do, with low added latency and no model changes.

It also runs Gandalf, a gamified red-teaming platform used to source adversarial data. API-first, with a free tier and sales-led plans. Acquired by Check Point.
