Developing and protecting critical national infrastructure for the UK's digital future

We examine how the UK can safeguard its critical national infrastructure (CNI) — building secure, resilient infrastructure that supports the nation's current needs and those of decades to come.

In our latest whitepaper, we examine how the UK can safeguard its critical national infrastructure (CNI). By first of all establishing the importance of dependable infrastructure and the reliance that the modern world has on it, we explore how and why the UK's infrastructure needs to be reliable and resilient, highlighting the need to employ infrastructure that supports the UK's current needs as well as the needs in decades to come.

AI and the demand for connectivity are changing the way that people live and work, and future developments depend on the integrity of the physical infrastructure that supports them. Transportation, electricity, telecommunications and data centres are growing increasingly interrelated, changing the role of infrastructure providers, who must now consider how infrastructure is developed, safeguarded, maintained and upgraded over time, rather than solely focusing on network deployment.

The UK needs to remain globally competitive by keeping up with demand and ensuring that its infrastructure remains secure, resilient and able to meet future demand. It is no longer just about building fast, the following needs to be considered:

Critical National Infrastructure, the Backbone of the Digital Economy

Uninterrupted connectivity is a fundamental element of modern life. The infrastructure sustaining data services and communications has therefore become equally essential to the nation's functioning.

Why Infrastructure Providers Must Think Beyond Traditional Networks

The infrastructure of today must do more than connect communities and businesses. It must be able to accommodate new technologies, adjust to shifting demand patterns, and withstand disruptions.

Lasting Infrastructure

For years to come, the infrastructure constructed today should offer a solid basis for the UK's connectivity requirements.

Protecting the Physical Assets Behind the Digital World

Critical infrastructure also faces a wide range of threats. Providers need to plan for physical attacks (severe weather, theft, fire) and cyberattacks (unwanted access, intentional interruption).

How Infrastructure Can Unlock Opportunity Across the UK

Investing in dependable, scalable infrastructure that can accommodate shifting demand and give communities the long-term connectivity they need to thrive is necessary.

Sovereignty, Security and the Future of CNI

The need for safe, dependable data infrastructure is essential as AI and data-intensive technologies continue to proliferate. Sustaining trust in the UK's digital future depends on building secure, resilient, and integrated infrastructure.

As the economy and society become more digital, the need for data infrastructure becomes more essential to the functioning of the nation. The infrastructure needed goes beyond physical assets. It includes facilities, systems, sites, information, people and networks. Very often, CNI sits at the heart of these interconnected systems, enabling the services that people and businesses rely on daily. Uninterrupted connectivity is key in modern life, and without capable infrastructure to support them, none of these systems can operate.

Infrastructure also needs to accommodate new technologies, withstand disruption and high levels of demand. Increased interconnectivity also means that operators must now work together to make the delivery and development of CNI more co-ordinated rather than considered separately. This involves providers taking more accountability for the part their networks play in wider infrastructure, ensuring facilities support vital services and advance long-term growth rather than only increasing connectivity.

Critical infrastructure also faces a wide range of threats. Providers need to plan for physical attacks (severe weather, theft, fire) and cyberattacks (unwanted access, intentional interruption). How can they strengthen their network's resilience? In the case of cyberattacks, plans should be built into network design from the outset. Back up infrastructure and alternate routes help to prevent significant disruption if a single asset fails. To physically protect networks, it's important to prevent tampering or sabotage by ensuring only those designated to repair and provide maintenance to the infrastructure are able to access it.

Connectivity can enable regional growth, expanding economic opportunity outside of major cities. Infrastructure can therefore continue to assist underserviced and rural industries if networks are built with adequate capacity and scalability. Building high speed, resilient infrastructure necessary for more people to fully engage the UK's digital future is the goal.

Data sovereignty is also an important consideration in the future of CNI: the networks, data centres and infrastructure needed to store and process data are inextricably linked to it. Knowing who has access to it, who controls it, and having confidence that it's being powered sufficiently is key in avoiding disruptions and interferences. Data sovereignty ultimately depends on infrastructure sovereignty.

Overall, the quality of the underlying CNI will determine the UK's future digital trajectory. Building infrastructure that can endure disturbances, adjust to demand and provide long term support is more important than simply installing networks quickly. Long term performance, resilience, physical security and sovereignty need to be considered. Building infrastructure that can support the UK in the future, as well as meeting current needs, must be the main priority for providers.
