Lakera provides real-time AI security that protects LLM applications from prompt injection, jailbreaks, data leakage, and toxic content. Lakera Guard is a low-latency API that scans inputs and outputs to detect and block attacks before they reach the model. The platform defends against the OWASP Top 10 for LLMs and is used by enterprises to secure customer-facing AI applications.
NVIDIA NeMo Guardrails is an open-source toolkit for adding programmable guardrails to LLM applications. It provides a modeling language (Colang) for defining conversation flows, topic boundaries, safety checks, and fact-checking rails. Integrates with any LLM and supports both input and output validation.
