NCSC Launches SilentGlass to Secure Monitor Connections Against Cyber Threats On April 22, 2026, the UK National Cyber Security Centre (NCSC) introduced SilentGlass, a plug-and-play device designed to protect video connections from cyber-attacks. This device actively blocks unexpected or malicious HDMI and DisplayPort connections, addressing a significant vulnerability in monitor security. SilentGlass has been successfully deployed in high-threat environments, including government estates, and is now available for global purchase. The NCSC, in collaboration with Goldilock Labs and Sony UK, aims to enhance cybersecurity for organizations handling sensitive data. The device is expected to see rapid adoption among governments and businesses concerned about cybersecurity risks. The NCSC highlights that monitors are attractive targets for cyber threat actors due to the sensitive information they display. SilentGlass represents a shift towards treating hardware interfaces as critical security boundaries, previously overlooked in cybersecurity measures. The launch was announced during the CYBERUK 2026 conference in Glasgow, Scotland. 9 sources 46
