NCSC SilentGlass

NCSC SilentGlass is the first commercially available hardware product to carry UK National Cyber Security Centre branding. NCSC developed the underlying intellectual property and licensed UK company Goldilock Labs to manufacture and sell it globally. Production is in partnership with Sony UK Technology Centre in Pencoed, Wales, making it a British hardware manufacturing story as well as a government commercialisation milestone. NCSC launched the product on 22 April 2026 with confirmation that it is already deployed in UK government high-threat environments.

SilentGlass is a plug-and-play hardware device that sits between a display cable — HDMI or DisplayPort — and its target device. It blocks the class of attacks where a malicious cable or peripheral uses the display interface as an injection vector: supply-chain interdiction of display hardware, physical-access cable substitution at a desk, and HDMI-borne electromagnetic side-channel capture. These physical-cable injection paths bypass software-layer defences entirely because they operate at the hardware signalling level before any operating system or security software can inspect traffic. The product is described as world-first for this attack class.

SilentGlass lands in the same week as the Beazley and Airbus/Ultra Cyber transactions. The commercialisation model — NCSC retains ownership of the underlying IP and licences a commercial operator rather than transferring the IP — distinguishes it from those two transactions. It keeps strategic inventions in UK-controlled ownership while making them available for civilian and commercial use. NCSC's commercialisation creates a template for future government IP to reach the market without sovereignty loss.
