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.
Robust Intelligence, acquired by Cisco in late 2024, provides AI validation and protection. Now integrated into Cisco's security portfolio, the platform offers automated red-teaming, continuous model validation, and runtime firewall protection for LLM applications. It detects adversarial attacks, data poisoning, hallucinations, and prompt injections across the AI lifecycle.
