Tenna Systems Tenna is a software-driven spectrum intelligence company. We make wireless interference — the jamming and spoofing that disrupt navigation, communications, and timing — visible, attributable, and survivable. No new hardware: we run on the sensors our customers already field. Our platform sees interference in real time, attributes it to its source, and keeps systems operating through it. And because it runs on sensors already deployed — from satellites and aircraft to handheld receivers — accuracy compounds as the network grows. Three capabilities, one idea: ARENA builds the picture — where the spectrum is clean, degraded, or denied. TRACER locates the source — and classifies what's behind it. HALO protects the platform — keeping systems operating through interference Tenna is operationally deployed in contested environments, built for operators who can't afford to lose navigation, timing, or communications: defense, aerospace, maritime, autonomous systems, and critical infrastructure. The spectrum is now a contested domain — and largely an invisible one. We're building the layer that makes it legible.
