Making AI safe to deploy and fast to trust

A deterministic AI firewall that stops threats at hardware speed, so enterprises can deploy AI with confidence and control.

Lucien makes AI safe to use by exposing and stopping hidden threats.

Our Story

Prototyped in Austin. Built in Texas. Deployed where AI can't fail.

Lucien was founded by defense cybersecurity engineers who spent years protecting high-assurance systems in defense, banking and healthcare. They saw organizations adopting AI faster than they could secure it, with guardrails that were probabilistic, cloud-bound and expensive. So they built a deterministic firewall for AI: in hardware, on your premises, same answer every time.

01

Proven in the lab

Prototyped in Austin

The first Lucien prototypes were designed and tested in Austin, where the founding team proved that rule-based inspection on FPGA hardware could beat model-based guardrails on speed, cost and certainty.

02

Built to order

Made in Texas

Production appliances are manufactured and assembled in Texas, where every unit is built, tested and shipped.

03

Installed by us

Deployed where it matters

Today Lucien appliances protect AI traffic for government, healthcare, financial services and other regulated organizations, installed on-premises by the engineers who built them.

Deploy with certainty, scale without hesitation

Your AI investments deserve protection you can prove. Let us show you how Lucien delivers it.
