The global technology landscape is rapidly evolving across the globe, where the UK stands out as a vibrant hub for technological advancements. Despite this momentum, the country faces ongoing challenges, including legacy systems, cybersecurity threats, and data fragmentation.
What are the risks and costs associated with legacy technology in the public sector?
Legacy technology exposes the UK public sector to mounting risk and expense because many critical systems run on unsupported platforms that cannot evolve with policy or service demands. Evidence from Gov.UK and the NHS shows rising red-rated systems, operational disruption, and safety implications, therefore making targeted, cost-conscious modernisation urgent.
Across the UK public sector, reliability is paramount, and yet many foundational platforms remain outdated or unupgradeable. Research from Gov.UK and the NHS shows how widespread the issue has become, and why risk, cost, and service quality are increasingly intertwined.
- Systemic exposure across government and critical services: While reliability remains critical, a significant share of estates now qualifies as legacy. According to Gov.UK research, approximately 28% of the central government technology estate is legacy, and comparable or higher figures are reported across the NHS, ranging from 10% to 50%. Between 2023 and 2024, the same research recorded a 26% increase in red-rated systems, and these platforms often carry security gaps, receive no vendor support, and fail to align with changing requirements, potentially endangering national security, public health, and personal safety.
- NHS operational impact and patient safety: According to the NHS, while a GBP 900 million investment was made to modernise digital infrastructure, many trusts still rely on fragmented, outdated, or hard-to-maintain systems. In the same report, legacy issues continue to disrupt hospital operations across the UK, and nearly half of NHS hospital trusts report difficulties with electronic patient record (EPR) systems. These outdated or poorly integrated platforms struggle to meet modern clinical demands, thereby compromising the reliability of critical patient information and the overall quality of care.
To support organisations, FPT provides comprehensive legacy modernisation solutions across healthcare, public services, transportation, and BFSI. Recognising that cost management and operational efficiency are essential, FPT employs a flexible global delivery model that blends onshore, nearshore, and offshore resources for 24/7 support and rapid scaling. Driven by a strategic focus on AI, FPT integrates innovations through EMT (Engineering Platform and Modernisation Technologies), xMainframe, and CodeVista. By leveraging xMainframe—an advanced LLM that understands and interacts with legacy mainframes and COBOL—clients have seen a 30% reduction in onboarding time, accuracy rates of up to 97%, and efficiency reported as six times higher than previous models such as ChatGPT 3.5 and 4.
What cybersecurity threats are rising and how do they affect public sector organizations?
Cybersecurity threats are rising as geopolitical tensions, AI-enabled attacks, and expanding digital estates amplify both frequency and severity. UK data shows more nationally significant incidents and widespread breaches, while many leaders feel underprepared. Strengthening end-to-end defenses, governance, and identity controls can reduce risk, and proven approaches already demonstrate measurable impact.
Cybersecurity threats are escalating rapidly, and the UK’s National Cyber Security Centre (NCSC) reported a 50% increase in nationally significant incidents in 2024 and a threefold rise in incident severity. This shift reflects a more complex threat landscape, intensified by geopolitical tensions and the growing use of AI in cyber operations.
The private sector remains highly vulnerable, and 50% of UK businesses reported breaches in the past year while 75% have now made cybersecurity a senior leadership priority, according to the 2024 UK Cyber Security Breaches Survey. These attacks could have been mitigated with robust cybersecurity and data protection practices; however, according to the State of Digital Government Technical Leadership Survey, only 50% of digital government leaders expressed confidence in their ability to prevent a breach.
Against this backdrop, FPT—drawing on extensive experience in cybersecurity, a vast pool of data experts, and strict adherence to global compliance standards—can deliver comprehensive solutions spanning the entire cybersecurity lifecycle. FPT’s standardised cybersecurity management packages are designed to detect and neutralise threats before deployment, therefore reducing risk, time, and complexity. FPT has joined the Microsoft Intelligent Security Association (MISA) as its first member in Vietnam, which underscores the company’s expertise and strengthens its position as a Microsoft Solutions Partner in Security.
FPT has helped the global customer base strengthen security posture through innovative solutions. For instance, a leading conversation intelligence company struggled to manage identities across Microsoft Azure and AWS as it expanded, and establishing a Zero Trust framework became increasingly challenging. The client adopted FPT’s Identity Governance to automate identity workflows and cut administrative overhead by 40%. This automation freed IT teams to focus on strategic initiatives, and streamlined processes contributed to a 70% decrease in unauthorised access attempts. These results highlight the effectiveness of FPT’s approach in protecting sensitive information and mitigating risk.
How does underutilized and fragmented data limit AI training and innovation?
Data is often underutilised and fragmented for AI because legacy systems and poor interoperability create silos, and policy efforts have moved slowly. High costs, inconsistent governance, and cultural barriers limit sharing. Consequently, AI initiatives struggle with quality and access, whereas integrated strategies and expert support can unlock value and speed adoption.
Many organisations still rely on outdated infrastructure and non-interoperable systems, and this combination entrenches data silos that hinder collaboration across departments. However, fragmentation is not caused by technology alone; it is reinforced by cost pressures and organisational norms that resist data sharing and standardisation.
Legislative and programme efforts have begun to address the problem, and yet progress remains uneven. Complex approval processes and limited enforcement slow momentum, while inconsistent data governance prevents reuse at scale. Therefore, coordinated investment in modern infrastructure and common standards is essential to realise the UK’s digital and AI ambitions.
The themes below are grouped by drivers, policy context, risks, adoption gap, and solution pathways to clarify what is blocking progress and what can be done next:
1. Causes of fragmentation: Systems that do not talk to each other keep data locked within lines of business, and organisational incentives often favour control over collaboration. As a result, the practical cost of integration rises while trust and data quality decline.
- High API costs that discourage integration at scale
- Inconsistent data governance across departments
- Cultural barriers, including strong data ownership and hesitation to share or aggregate personal data
2. Policy efforts and constraints: Initiatives such as the Digital Economy Act 2017 and the ONS Integrated Data Service have set direction, and yet progress has been slow due to complex approvals and limited enforcement. This creates uncertainty, and it reduces the incentive to invest in long-term integration.
3. Consequences and national risk: Without coordinated modernisation and standardised data management, the UK risks falling short of its digital and AI ambitions. Moreover, the opportunity cost compounds as projects duplicate effort, and valuable insights remain trapped within silos.
4. Underutilisation in AI programmes: AI holds vast potential, with over 140 use cases identified across central government. However, research indicates that poor data quality and limited accessibility frequently hinder implementation, and this turns promising pilots into stalled initiatives.
