Open Source LLM Guardrails: The Libraries Available, Where They Sit, and What They Cannot Replace

Open source LLM guardrails libraries cover prompt-side and response-side filtering inside the application or inference path. Llama Guard, NeMo Guardrails, Guardrails AI, LMQL, and Rebuff each occupy a different position in the stack and produce different control surfaces. This piece walks through the libraries available, the architectural position each one takes, the controls they produce, and the regulatory profile that requires an external inspection layer on top of any of them.

LLM Firewall: How the Inspection Layer Differs From a Network Firewall and a Model Guardrails Library

An LLM firewall is the inspection layer that sits inline between the calling identity and the LLM endpoint, evaluating identity-bound policy at the HTTP request boundary and committing a per-decision audit record. The layer differs from a network firewall (which inspects TCP and TLS metadata) and from a model guardrails library (which runs inside the inference path). This piece walks through the inspection target the LLM firewall has, the request-time decisions the layer commits, the deployment topology that fits a production stack, and the audit record the layer produces.

AI Firewall: What It Actually Inspects, Where It Sits, and the Audit Record It Produces

The phrase "AI firewall" gets applied to four very different products. The category collapses when you ask what each one inspects, where in the request path the inspection happens, and whether the record series survives EU AI Act Article 12 review. This piece walks through the four product shapes that get marketed as AI firewalls, the architectural property each one has and lacks, the inspection target the term should refer to in a regulated deployment, and the audit record the inspection layer commits at decision time.
