The spy in the room is a
signal.
We find it.

Today’s covert devices hide inside ordinary wireless traffic – a phone, a bug, a tracker, all speaking the same signals your building runs on. SHYAM builds the instruments that find them: what it is, where it is, and why it matters. Conceived, designed and made in India for over five decades.

Why detection has to change

Old Bug Detector's and instruments were built to find yesterday's bugs.

Think of an outdated blood test: slow, limited, and unable to see a new virus it was never designed for. Most security screening is the same. Metal detectors, x-ray scanners and general-purpose RF tools were never built to see a modern wireless device — so the single most capable spying tool a person can carry walks straight through.

We build the diagnosis for the threats of today - clear, fast, and readable by anyone.
