The Government Just Proved That Good Cybersecurity Doesn't Have to Be Complicated

Published by Prestige Cyberguard | June 2026

A quiet but significant announcement came out of the UK government last month — and if you run a business, it's worth paying attention to.

The National Cyber Security Centre (NCSC), the government's own cybersecurity authority and part of GCHQ, has just commercially licensed a piece of technology it built for internal use. The device is called SilentGlass, and the story behind it tells us something important about where the UK's approach to cybersecurity is heading — and what it means for businesses like yours.

So what is SilentGlass?

Here's the simple version: SilentGlass is a small plug-and-play device that sits between your laptop and your monitor. That's it.

What it does is block a surprisingly common attack route — the physical video cable. As modern monitors have become "smarter" (think USB-C docking stations, monitors with built-in hubs, shared screens in hot-desking environments), that cable connection has become a potential way in for attackers. SilentGlass removes that risk entirely, without requiring any software, any configuration, or any specialist knowledge to use.

The technology was originally developed for internal government use within the NCSC, but has since demonstrated clear potential for wider adoption across the public sector, critical national infrastructure, and the private sector.

Following a competitive process, a UK-based company has now been granted a global licence to manufacture and sell the device — meaning it's available to businesses right now, not just government departments.

Why this matters for UK SMEs

You might be thinking: "That sounds like something for large enterprises or government agencies." We'd push back on that.

Think about how your business actually operates today. Hybrid working. Hot-desking. Employees plugging their laptops into monitors at home, in the office, in co-working spaces. Every one of those connections is a potential attack surface — and most businesses have no protection against this specific risk whatsoever.

SilentGlass supports organisations that need high-assurance protections for connected devices, including businesses with high cyber security requirements and employers enabling flexible and hybrid working.

That description fits a huge proportion of UK SMEs in 2026.

The bigger picture: the government is taking cyber seriously

What's really notable about this story isn't just the device itself — it's what the announcement represents.

The government has, for the first time, taken a cybersecurity tool built by its own intelligence-linked agency and made it commercially available to the private sector. That's a meaningful shift. The Government Office for Technology Transfer (GOTT) supported the NCSC to shape the commercialisation of SilentGlass, advising on appropriate intellectual property licensing strategies and facilitating access to the tech transfer ecosystem.

NCSC Chief Technology Officer Ollie Whitehouse described it as "breaking new ground, showing the impact that the NCSC can have, alongside industry partners, with an affordable and effective product now globally available."

The word "affordable" is doing real work in that quote. This is government-grade security being made accessible to ordinary businesses, not just organisations with enterprise-level budgets.

What this tells us about the threat landscape

The NCSC doesn't build things for fun. SilentGlass exists because video connections from monitors were being exploited in real attacks — including in secure government facilities. If GCHQ considered this a serious enough threat to invest in dedicated hardware, it's a threat the rest of us should take seriously too.

This is part of a broader pattern. Attackers are increasingly targeting the physical and overlooked edges of your network — shared peripherals, USB devices, printers, monitor connections — precisely because most businesses focus their security budget on firewalls, antivirus, and email filtering. The basics are necessary, but they don't cover everything.

What should you do with this information?

First, if hybrid or flexible working is part of how your business operates, it's worth understanding whether your current setup leaves you exposed through peripheral connections. A lot of businesses have never considered this risk.

Second, developments like SilentGlass are a reminder that good cybersecurity doesn't have to mean complexity. The best security controls are often the simple ones — the ones that work without training, without configuration, without ongoing management. Plug-and-play protection is exactly the kind of practical, proportionate solution that SMEs should be looking for.

Third — and this is where we come in — understanding which risks are most relevant to your specific business, and which solutions are worth investing in, requires someone to look at your situation properly. A threat that's critical for one business may be low-priority for another, depending on your setup, your sector, and the regulations you operate under.
