UK’s National Cyber Security Centre launches device to protect display connections from cyber threats
SilentGlass has been introduced to prevent malicious connections between devices and screens in high-risk environments.
The National Cyber Security Centre (NCSC) has developed SilentGlass, a device designed to protect display connections from malicious or unexpected activity. It is the first commercially available product licensed to use NCSC branding and was launched at CYBERUK.
SilentGlass blocks unauthorised interactions between HDMI and DisplayPort connections and screens. The NCSC stated that threat actors can target monitors as they may process sensitive or personal data.
The intellectual property has been licensed to Goldilock Labs, which is manufacturing the device in partnership with Sony UK Technology Centre. The product has already been deployed in government environments and approved for use in high-threat settings.
The NCSC noted that increasing numbers of connected devices raise exposure to risks linked to physical interfaces. SilentGlass has been developed to address this risk by preventing malicious connections at the hardware level.
