Why Infrarails Guard
Multi-Layer Evaluation, Not Single-Model
Lakera relies on a single proprietary model for detection. Infrarails Guard layers dozens of proven evaluators — ML models, LLM judges, and heuristic checks — for defense in depth that catches what single models miss.
Full TSGRC Coverage, Not Just Safety
Lakera focuses on prompt injection and toxicity. Infrarails Guard evaluates across all six TSGRC&S pillars — Trust, Safety, Governance, Risk, Compliance, and Security — so you get security AND governance in one integration.
Deploy Anywhere, Including Air-Gapped
Regulated industries need on-prem deployment. Infrarails Guard runs fully on-premise with zero external calls. Your data never leaves your infrastructure — a requirement Lakera's cloud-only model cannot meet.
