Building Cyber Resilience Into Government Digital Infrastructure
As government departments accelerate digital transformation, the infrastructure underpinning that progress faces unprecedented pressure. Data volumes are growing, threat actors are becoming more capable and more brazen, and citizens expect services that are both seamless and secure. Delivering on that expectation requires more than government action alone, it demands genuine, sustained partnership with industry.
By creating trusted environments for secure data sharing, embedding security by design, and building AI-ready cyber defences, industry can decisively strengthen the digital and data foundations that public services depend on.
What role can industry play in strengthening public sector data infrastructure?
Government departments, local authorities, defence organisations, and critical national infrastructure (CNI) providers generate vast amounts of high-value data every day. Shared securely across organisational boundaries, that information enables better decisions, stronger service delivery, and more effective responses to national challenges. But it is also a target. The transmission and sharing of sensitive information represent a live attack vector, one that bad actors and state-sponsored threat groups actively exploit.
Unlocking data's full value, then, depends on building trusted environments where information can be managed according to its sensitivity and shared without compromising security. This is where industry has a decisive role to play. Technology providers bring the secure collaboration platforms, encryption standards, and access controls needed to protect information throughout its entire lifecycle, not just at the network perimeter.
As my colleague John Platt outlines in his article on the four pillars of cyber security, strong information protection must allow teams to "collaborate at mission pace, underpinned by protection that does not compromise assurance".
Why is cyber resilience becoming more urgent for government systems?
The threat landscape is not just evolving, it is accelerating. In October 2025, the Russian-linked group Lynx breached a Ministry of Defence contractor and exfiltrated approximately 4TB of sensitive data, including files relating to RAF and Royal Navy bases. Months earlier, a ransomware attack on NHS pathology provider Synnovis disrupted diagnostic services across South-East London and delayed thousands of patient appointments, a stark demonstration of how a single supplier compromise can cascade across critical public services.
The UK's National Cyber Security Centre has assessed that AI will make cyber intrusion more effective and efficient, increasing both the frequency and intensity of attacks. AI minister Kanishka Narayan has acknowledged earlier this month that it is "likely, if not inevitable" that UK cyber defences will at some point be breached, pointing to an AI agent's successful hack of an Australian government website as an early warning.
This is precisely where industry expertise becomes indispensable. Government has already begun piloting AI-driven vulnerability detection, identifying and remediating over 1,000 vulnerabilities across public sector systems. But scaling that capability and building the technical depth needed to match a rapidly evolving threat, requires sustained collaboration between public bodies and the technology partners equipped to deliver secure-by-design infrastructure at pace.
How can government and industry build this resilience together?
When it comes to putting this government-industry collaboration into practice, four strategic priorities stand out:
Secure by design, not bolted on. Security must be embedded into digital services from the earliest design decisions. Continuous assurance frameworks should replace point-in-time accreditation, because resilience built in from day one is fundamentally stronger than security retrofitted under pressure.
Trusted data-sharing environments. Government and industry must jointly invest in platforms that allow sensitive information to move securely across organisational boundaries, enabling collaboration without sacrificing the sensitivity controls that protect it.
AI-ready defences. As both the NCSC and senior government ministers have signalled, AI will fundamentally reshape the threat landscape. Industry can help government stay ahead by applying AI to detection, response, and vulnerability management, while maintaining rigorous governance over how AI tools interact with sensitive data.
Proactive Resilience over Reactive Response. The most robust organisations don't simply plan for what happens after an attack, they build operations that can absorb, adapt, and continue functioning through one. This means designing systems with redundancy, fault tolerance, and continuity built in from the ground up, so that mission-critical services hold when it matters most. True resilience means assuming breach and engineering for continuity, not just survival.
Strengthening the foundations of digital government
Digital and data infrastructure is now central to how government serves citizens and safeguards national interests. The stakes are clear, and so is the opportunity. Industry's expertise in secure design, advanced data protection, and AI-driven resilience gives public sector partners the capability to meet rising threats from a position of strength, not in response to failure. The organisations that invest now in trusted, secure-by-design infrastructure will be best placed to deliver stronger, more resilient public services for years to come.
