Summary

New device designed by the National Cyber Security Centre protects against malicious connections between monitors First commercially available product licensed to use NCSC branding granted to Goldilock Labs in partnership with Sony An innovative device which protects video connections from cyber attacks is being launched to the global market at CYBERUK, the UK government’s flagship cyber security conference. The National Cyber Security Centre (NCSC) – a part of GCHQ – created the intellectual property for a new cyber security device and has now licensed Goldilock Labs to manufacture and sell it globally. SilentGlass, a plug-and-play device, actively blocks anything unexpected or malicious between HDMI and Display Port Already successfully deployed on Government estates, SilentGlass is now available for anyone to buy and use. It has been approved for use in the most high-threat environments. The NCSC assesses that monitors can be a hugely attractive target for threat actors as they can hold and process valuable, sensitive or personal data.
