Lakera
AI GovernanceFreemiumVisit Site
An AI security platform that defends LLM applications against prompt injection, jailbreaks, data leakage, and other model-layer attacks.
Overview
Lakera focuses on a threat class that traditional security tools miss: attacks aimed at the model itself — prompt injection, jailbreaks, and attempts to extract sensitive data through the LLM. Lakera Guard inspects inputs and outputs in real time to block these, informed by a large, continuously updated threat dataset. For any enterprise exposing an LLM application to untrusted users or external content, this AI-native firewall layer addresses risks an application team cannot reasonably hand-roll. Lakera was acquired by Check Point in 2025, aligning it with a broader enterprise security portfolio.
