NCSC’s SilentGlass Device Shields Monitors from Cyber-Attacks
▼ Summary
– The UK NCSC launched SilentGlass, a plug-and-play device that blocks malicious activity between display connections and monitors, on April 22 at the CYBERUK conference.
– SilentGlass is approved for high-threat environments and has already been used on government estates before being released for public purchase.
– The NCSC partnered with Goldilock Labs and Sony UK to manufacture and sell SilentGlass globally.
– The NCSC warns monitors are attractive targets for cyber-attacks due to their access to sensitive data, and SilentGlass aims to close this vulnerability.
– Goldilock Labs’ co-founder noted that SilentGlass addresses a widely overlooked security gap in hardware interfaces, now available as a low-cost solution.
The UK’s National Cyber Security Centre (NCSC) has introduced a new hardware solution aimed at neutralizing cyber threats targeting video connections. Called SilentGlass, the device was unveiled on April 22 at CYBERUK, the government’s premier annual cybersecurity conference held this year in Glasgow, Scotland.
SilentGlass is a plug-and-play tool designed to actively intercept and block any unexpected or malicious activity traveling through HDMI or DisplayPort connections before it reaches a monitor. It has been approved for deployment in the most demanding, high-threat cybersecurity environments. Already successfully used across government estates, SilentGlass is now available for purchase by any organization.
The NCSC partnered with Goldilock Labs and Sony UK to manufacture and distribute SilentGlass globally. The device addresses a specific vulnerability: monitors are often overlooked as security risks, yet they process and display valuable, sensitive, or personal data. According to the NCSC, threat actors may exploit access to monitors to infiltrate networks, seeking disruption or financial gain by taking advantage of weak protections in this area. SilentGlass aims to close that attack vector.
“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 device’s development and commercialization demonstrate the impact the NCSC can have with industry partners, delivering an affordable, effective product now available worldwide. “By helping to launch a UK company onto the global market with this world-class innovation, we are breaking new ground and helping to strengthen national prosperity.”
Goldilock Labs, a UK-based small business specializing in cybersecurity innovation, won the contract to manufacture SilentGlass through a competitive process. Stephen Kines, co-founder of Goldilock Labs, noted that the device addresses a widely overlooked gap. “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 said. “What was once confined to national security environments is now being applied with a low-cost, easy to deploy solution for CNI and businesses where the same risks exist.”
Goldilock, Sony, and the NCSC anticipate rapid global adoption of SilentGlass by governments and risk-conscious organizations. The NCSC highlighted the device as a prime example of how government intellectual property can be successfully commercialized. The announcement came during CYBERUK 26, where NCSC CEO Richard Horne warned in his opening speech that a “perfect storm” of emerging technologies and geopolitical tensions has created an unprecedented level of cyber threat for the UK.
