NCSC device blocks HDMI cyber espionage attacks
▼ Summary
– The NCSC developed SilentGlass, a plug-and-play device to protect HDMI and DisplayPort connections from cyberattacks.
– Monitors are attractive targets for attackers because they process sensitive data and can be exploited for espionage or financial gain, with existing protections being costly.
– SilentGlass is designed to be an affordable and effective solution for previously vulnerable IT infrastructure, according to NCSC CTO Ollie Whitehouse.
– The technology has been deployed in government systems, approved for high-threat environments, and is now available for commercial purchase.
– Goldilock, in partnership with Sony UK Technology Centre, manufactures and distributes SilentGlass under license from the NCSC.
A new piece of cybersecurity hardware from the National Cyber Security Centre (NCSC) is stepping in to close a dangerous blind spot in digital defense. The device specifically targets malicious activity that can be launched through common display connections.
Named SilentGlass, this plug-and-play tool is engineered to protect HDMI and DisplayPort links from potential cyberattacks. Its compact design allows for immediate deployment without complex configuration.
The NCSC highlights that monitors are often overlooked as a security risk, yet they process and store sensitive data. This makes them a prime target for attackers seeking to infiltrate networks for espionage, disruption, or financial theft. Existing protective measures, the agency notes, are frequently too expensive or inefficient to implement at scale.
“Display screens and monitors are everywhere in modern business environments, and the SilentGlass device will help protect previously vulnerable IT infrastructure with unprecedented ease,” said Ollie Whitehouse, CTO at NCSC. He added that the project demonstrates the tangible impact the NCSC can achieve alongside industry partners, delivering an affordable and effective product now available globally.
The technology has already been deployed within government systems and has received approval for use in high-threat environments. It is now available for commercial purchase.
Manufacturing and distribution are handled under licence by Goldilock, in collaboration with Sony UK Technology Centre.
Stephen Kines, Co-Founder at Goldilock Labs, emphasized the device’s importance. “SilentGlass addresses a gap that has been widely overlooked. The hardware interfaces people rely on every day have rarely been treated as security boundaries, despite being exposed to risk through supply chains, third-party servicing, and direct physical access.” He concluded that what was once limited to national security contexts is now accessible as a low-cost, easy-to-deploy solution for Critical National Infrastructure (CNI) and businesses facing the same threats.
