Lakera Guard
Lakera Guard is a low-latency screening API that inspects text content sent to or from LLMs and flags threats including prompt injection, jailbreaks, PII, profanity, and policy violations. The /guard endpoint returns a flagged decision plus optional detector breakdowns via /guard/results, and the platform exposes /policies and /projects endpoints for managing detection logic. Available as a managed SaaS at api.lakera.ai/v2 with regional endpoints (US, EU, APAC) and as a self-hosted deployment for regulated environments.
