Why the UK Must Think Again About Cyber Resilience, it’s crucial to reconsider this before it’s too late.

Introduction: The Myth of Security in Ongoing Connectivity

In this digitally networked world, every part of daily life, from healthcare systems to retail operations, is interconnected. These systems are linked with complex networks. Ongoing connectivity, erstwhile a badge of progress, is now a double-edged sword.

In 2025, “always on” equals “always vulnerable.”

Recent cyberattacks have brought top British retailers, health services, and even government systems to their knees, laying bare the vulnerabilities of our digital system. These incidents bring home a stark reality: what it takes years to build can be destroyed in seconds.

This is not an appeal to fear, but one for clarity and foresight. Disconnection is a must. A lack of knowledge and adoption can no longer serve as an acceptable excuse.

Part One: Cyber Threats Are Everybody’s Problem

Cyberattacks no longer selectively target. No organisation is out of reach from multinational businesses to local charities. Recent instances have highlighted the broad threat:

Retail Giants: Big-box stores have been taken down by ransomware attacks that halted operations, costing enormous money and reputations.

Healthcare Systems: Hospitals have been afflicted by breaches exposing patient data and delaying vital treatments.

Government Institutions: Senior-level attacks on government institutions have revealed public sector cybersecurity vulnerabilities.

These breaches are not isolated. They are indicative of a new trend that threatens the very fabric of our society.

Part Two: Global Trends Signal Urgency

The UK is not unique in its plight. Nations across the globe are confronted with the backlash of digital overexposure.

South Korea: SK Telecom replaced 23 million SIM cards after a serious security breach that disrupted banking services and eroded public trust.

Singapore: Mandated air-gap implementation in key public sector systems by default, separating them from potential web-based attacks.

Israel: Implemented strict physical segmentation of its defence and energy sectors, disconnecting sensitive systems from external networks.

France: Mandated disconnect-by-design architecture in sectors like aviation and finance, requiring some systems to be disconnected from the rest of the networks.

United States: Defence contractors and utility companies are increasingly turning to hardware-based disconnect technologies to protect critical infrastructure from advanced cyberattacks.

Examples overseas demonstrate the growing consensus: strategic disconnection is essential to resilience.

Part Three: Cybercrime’s Evolution Outpaces Defences

The National Cyber Security Centre (NCSC) marks a paradigm shift in cyber threat. Ransomware-as-a-service business models have lowered the barrier to cybercrime for even those with minimal technical expertise, and thereby they are able to cause havoc.

“Cyber criminality… is one of the most pervasive threats facing UK organisations. It is opportunistic and indiscriminate.” —Jonathon Ellison & Ollie Whitehouse, NCSC

In such an environment, traditional defences are insufficient. Organisations must anticipate breaches and possess robust contingency measures in place for immediate damage containment.

Part Four: Disconnection as a Strategic Imperative

With the admission that breaches are inevitable, focus must now be given to reducing the impact of attacks.

This entails:

Isolating mission-critical systems to prevent lateral movement for attackers.Facilitating rapid recovery through uninfected backups.

Facilitating physical disconnection mechanisms that can remove network access in a split second.

Strategic disconnection is not a matter of blocking operations; it’s ensuring integrity and trust during challenging times.

Part Five: FireBreak™ — A NATO DIANA Award-Winning Solution

FireBreak™ from Goldilock is a NATO DIANA award-winning appliance that provides organisations with the capability to physically disconnect digital assets from networks, ensuring complete separation when necessary.

Unlike software solutions, FireBreak™ is hardware-based, offering:

Non-IP remote control: Excluding vulnerability to network-based attacks.

Instant air-gap protection: Physically severing connections to prevent unauthorised access.

Out-of-band activation: Enabling safe shutdown regardless of potentially compromised systems.

This product is an important tool in the modern cybersecurity arsenal, enabling organisations to regain control during incidents and prevent catastrophic damage.

Part Six: Real-World Applications Across Sectors

Aviation: Aircraft systems can be encapsulated during critical points of flight, keeping control environments isolated from maintenance or passenger interfaces. FireBreak™ can be used at airports to protect baggage control, security systems, and airside operations—keep them up and running even if there’s a Cyber event.

Utilities: Power and water infrastructure may implement FireBreak™ to isolate operational technology from enterprise networks—limiting attack vectors to pumps, valves, and grid controllers. Physical isolation ensures vital supply is preserved, even if administrative network attacks do occur.

Healthcare: Hospitals segregate diagnostic devices, medical imaging stations, or patient records portals from general hospital networks, making total lockout impossible during a compromise.

Telecoms: Network infrastructure can be secured by FireBreak™ installations on the part of service providers, so communications services are not compromised.

Military & Defence: Military and defence establishments can have FireBreak™ installed to secure command systems and sensitive information against Cyber espionage. When there’s war, command platforms, surveillance data, or targeting systems don’t need to be on a network—they cannot be found, mapped, interrupted, or disabled.

FMCG/Retail: Retailers can use FireBreak™ to protect customer data and point-of-sale systems, enabling business continuity. Isolated systems can’t be scanned, exfiltrated, or encrypted, offering a true alternative to reactive breach response.

Banking & Finance: Banks and financial institutions can use FireBreak™ to protect transaction systems and customer data, maintaining trust and compliance. When systems are physically inaccessible, attackers can’t tamper, spoof, or even monitor them.

Part Seven: Taking Proactive Steps with InsightBull

At InsightBull, we help organisations move from reactive to proactive cybersecurity practices. This encompasses:

Vulnerability Assessments: Working with teams to identify the most critical systems to protect.

Disconnection Protocols Implementation: Utilise deep knowledge to ensure that Implementing solutions like FireBreak™ can enable real-time isolation during an attack rather than being a long term process.

Training and Awareness Programmes: Educating people to raise awareness on identifying threats and responding to them effectively.

Organisations can spearhead risk reduction and create resilience by developing a culture of preparedness.

Last Thought: Years to Build, Seconds to Lose

In a world where digital threats are ever-present, the cost of inaction is incalculable. The integrity of your organisation rests on the decisions of today.
