The zero trust firewall for AI

Model guardrails need the model to police itself. They can be bypassed. Lucien enforces policy outside the model, stopping adversarial inputs before they ever reach the model.

Probabilistic defenses use pattern matching and confidence scores. They tokenize inputs and run model-based evaluations. That adds latency, cost, and uncertainty. Lucien is deterministic. It uses explicit rules to evaluate inputs in fixed time, without tokenization or inference. This makes Lucien faster, lower cost to operate, and fully predictable. Every decision is rule-based and auditable.

Lucien evaluates prompts at sub-milisecond speeds. Hardware acceleration supports real-time protection without slowing applications or increasing compute cost.

Yes. Lucien is model-adgnostic. It integrates with commercial APIs, open-source models, proprietary models, and multi-model architectures.

Lucien can be deployed as SaaS, on-premises, or fully air-gapped. Each deployment provides the same deterministic enforcement and real-time auditability.
