L39 Tech Ltd is a specialist UK-based secure engineering firm providing bespoke AI systems and resilient defence architectures. At S&P 2026, we are debuting Project Cerberus: a patent-pending acoustic drone detection system.

Developed to eliminate the “blind spot” inherent in traditional radar and RF sensors, Cerberus utilises advanced AI ensemble models to detect, classify, and track UAV threats in zero-visibility and RF-silent environments. Whether securing prison perimeters or critical national infrastructure (CNI), L39 Tech delivers a decisive strategic advantage through Acoustic Intelligence.
