The UK government’s spending review in June set out its plans to invest in Britain’s renewal: its security, health and economy.

Digital technologies featured heavily in the review with government pledging that it will provide “funding directly to departments to build strong digital and technology foundations, modernize public service delivery, and drive a major overhaul in government productivity and efficiency.”

One of the ways it has done this is by introducing a GOV.UK Wallet and a GOV.UK App, which aims to deliver more personalized customer experiences and verifiable digital credentials for citizens.

This is now available to the public in beta form. The government is also creating a new National Data Library to join up data across the public sector and a single patient NHS record, which is due to be available by 2028, so that every part of the health service has a full picture of a patient’s care.

However, if the UK is to realize the benefits of its digital ambitions, it must ensure the public can trust the systems underpinning them.

The pros and cons of centralizing data

Centralizing citizen data and digital identities has clear benefits. It enables more joined up services, reduces duplications allows for more seamless, personalized user experiences and could improve access and efficiency across the NHS and other public services.

For the NHS, for example, a single patient record could help doctors and specialists deliver better, more consistent care across the health service. For citizens interacting with government departments, a unified app and wallet could simplify administrative tasks and improve digital inclusion.

Technology Secretary Peter Kyle has said in recent interviews that, “People’s private data will not be shared outside of government.” However, despite the Technology Secretary’s assurances, this approach does come with significant risks. Centralized citizen data represents some of the most sensitive information any organization could hold. Health records, identity details and government interactions, combined in a single system, are a goldmine for cybercriminals.

And no doubt there will be some concerns from the public regarding its security – particularly in light of recent, very public, high profile cyber-attacks. Over the last 18 months, the UK has seen a series cyber attacks on both public and private sector organizations, including health authorities and councils, as well as the recent M&S and Qantas data breaches.

These incidents have highlighted the vulnerability of critical services and the real-world impact of compromised data, from patient safety to public confidence.

As these services become more integrated and reliant on shared data infrastructure, the risk of a breach also grows. A single point of access to multiple datasets can become a high-value target for threat actors. The more data an attacker can obtain from one place, the more appealing, and damaging, a breach can be.

A proactive approach to information security

With these very real threats, a proactive, systems-led approach to information security must be embedded from the outset.

The government needs to ensure that privacy by design and security by default is in every digital service developed. This means applying rigorous access controls, encryption, and secure development practices across every data touchpoint. That said, it is crucial that continuous monitoring for vulnerabilities and suspicious activities happens throughout the system lifecycle – and not just after deployment.

Similarly, the systems need to ensure that they comply with UK GDPR, the Data Protection Act and other relevant standards.

These requirements must be seen not as a burden by the government but as the bedrock of responsible digital innovation.

Building a high-security posture

To meet these heightened security demands, following the guidance provided by internationally recognized security standards, such as ISO 27001, can be a logical place to start to get ahead of the increased risks to highly personal data this approach represents.

Standards such as ISO 27001 offer a structured, repeatable framework for managing risk, protecting information assets and demonstrating compliance. But it’s more than a tick-box exercise, it is a cultural shift in how risk is understood, communicated, and mitigated across every layer of an organization.

If the government embeds the principles of ISO 27001 into its delivery of these new services from the outset, rather than retrofitting them post-launch, it can design services that are both secure and scalable. It can ensure that it is identifying and evaluating new and emerging threats as digital services evolve.

It will also mitigate risks through policy, controls and continual improvement. But it will also be able to demonstrate accountability and transparency to the public – which is key.

Transparency is key to building public trust

Security isn’t just about systems, it is also about perception. The government’s digital strategy must be underpinned by public trust. Clear communication about how data is used, who has access, what safeguards are in place and what recourse citizens have in the event of a breach is essential.

Publishing high-level information security policies, adopting standards like ISO 27001 and engaging with the public on data protection issues will help foster the confidence needed to make digital services work.

Public sector leaders must ensure that information security is not treated as an afterthought. That means prioritizing risk management now – not waiting for a breach to expose the consequences of delay.
