Using an unordered list, summarize the following article with between 4 and 8 key points.
\n A new cybersecurity device developed by the National Cyber Security Centre (NCSC) should be a helpful solution for protecting governments and businesses from malicious activity carried through display connections. <\/p>\n

Called SilentGlass, the plug-and-play tool is designed to protect HDMI and DisplayPort links from potential cyberattacks.
\nThe NCSC warns that monitors are an attractive target for cyber attackers as they can process and store sensitive data, and are highly likely to be exploited to gain access to networks for espionage, disruption, or financial gain, while existing mitigations are often costly and inefficient.
\n\u201cDisplay screens and monitors are everywhere in modern business environments, and the SilentGlass device will help protect previously vulnerable IT infrastructure with unprecedented ease,\u201d said Ollie Whitehouse, CTO at NCSC.
\n\u201cIts development and commercialisation shows the impact that the NCSC can have, alongside industry partners, with an affordable and effective product now globally available,\u201d added Whitehouse.
\nThe NCSC states that the technology has already been deployed within government systems. It has been approved for use in high-threat environments and is available for commercial purchase.
\nThe device is being manufactured and distributed under licence by Goldilock, in partnership with Sony UK Technology Centre.
\n\u201cSilentGlass 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,\u201d noted Stephen Kines, Co-Founder at Goldilock Labs.
\n\u201cWhat 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,\u201d concluded Kines.<\/p>\n
