What Lakera is

Lakera is a security layer for LLM products: it inspects prompts and outputs for injection attacks, jailbreaks and data leakage, giving GenAI teams a defensive perimeter their models lack natively.

What you can do with it

Screen prompts for injection patterns
Block jailbreak and misuse attempts
Prevent sensitive data in outputs
Monitor attacks on your AI endpoints
Test your app against known techniques

Who it is for

Teams shipping LLM applications
Security groups covering AI products
Platform engineers running agents

What to watch out for

Category misplacement: AI infrastructure security, not content moderation
Prompt injection defences are an arms race; no layer catches everything, so layer with design and human oversight
Overly aggressive blocking breaks legitimate users; tune false positive rates
Free entry described; enterprise deployment pricing differs
