HM Government licensing cyber security tech for a global market

SilentGlass is a plug-and-play cyber security device developed by NCSC and commercialised with support from GOTT, now licensed to a UK firm for global use.

Added the name of the UK company responsible for the licence.

The National Cyber Security Centre (NCSC), a part of The Government Communications Headquarters (GCHQ), is the UK’s National Technical Authority on cyber security. It works round the clock to combat cyber threats, support victims of cyber incidents, empowers organisations to protect the online services and digital technologies that underpin the UK economy and public services. 

As modern computer monitors become increasingly ’smart‘, digital video connections can be exploited to compromise laptops and other connected devices. This risk is particularly acute in environments where devices of differing trust levels connect to shared monitors, including secure government facilities, hybrid office working, and home working set‑ups. 

SilentGlass was developed within the NCSC to address this challenge, providing a simple and effective way to prevent video connections being used as a route for cyber-attack. 

SilentGlass is a small, ’plug-and-play’ hardware device that sits between a laptop and a monitor, preventing the physical connection from being used as a route to compromise either device. By removing this attack pathway, it helps organisations improve cyber security while supporting safer flexible and hot‑desking arrangements. 

The technology was originally developed for internal government use, but has since demonstrated clear potential for wider adoption across the public sector, critical national infrastructure and the private sector. 

To bring the technology to market while maintaining strong governance and security considerations, the NCSC pursued a licensing‑based commercialisation route. 

SilentGlass supports organisations that need high‑assurance protections for connected devices, including: 

government departments and public sector bodies
