About
Tenna Systems is building the “Signal Source of Truth” — a software-driven spectrum intelligence platform delivering real-time, global visibility into wireless connectivity. Founded in 2023 with offices in Tel Aviv and New York, Tenna combines elite SIGINT and electronic warfare expertise to transform existing sensor data into actionable threat detection, precision geolocation, and operational resilience. The company's platform analyzes millions of data points per minute from existing emitters and turns them into a real-time, high-resolution map of the RF environment. Tenna currently offers three core products: Arena, Tracer, and Halo. Arena monitors radio frequency (RF) coverage gaps and interference in real time; Tracer locates the precise geolocation of interference sources to enable mitigation; and Halo acts as embedded software “armor,” protecting platforms from jamming in contested environments.
