The public sector’s growing reliance on digital services is placing increased pressure on network infrastructure to deliver secure, reliable and resilient outcomes, says David Nuti, Head of Security Strategy, Extreme Networks.
The network is the backbone of the public sector. It links departments, frontline workers and the public across a range of essential services such as healthcare, education, housing and transport. As reliance on digital services continues to grow, it has become a critical foundation for delivering secure, reliable and resilient public services.
With this growing reliance comes increased responsibility. As public services expand in scale and complexity, so too does the need to deliver them securely. IT teams are expected to navigate highly regulated, risk-averse environments where security, compliance and operational resilience are non-negotiable. They must protect sensitive data, ensure always-on connectivity for essential services and simultaneously drive Digital Transformation strategies, all while managing budget pressures and an evolving threat landscape.
At the centre of all these demands sits a robust network infrastructure. Get that wrong, and everything built on top risks toppling over.
The public sector is now in the crosshairs
While the private sector remains a lucrative target for threat actors, the public sector is facing similarly sustained pressure, driven in large part by the volume and sensitivity of the data it holds.
Recent examples underscore the scale and complexity of the challenge. From disruptions affecting critical services to data exposure incidents within local authorities, organisations are navigating an increasingly sophisticated threat landscape.
It’s clear why the public sector is such an appealing target. Public institutions manage vast stores of highly sensitive datasets, including names, addresses, tax records, health information and login credentials. If compromised, this data can be used for identity theft, financial fraud and increasingly sophisticated social engineering attacks. The impact also goes beyond financial loss, disrupting essential services and damaging public trust.
The reality is that many public sector organisations deliver critical services through underfunded and under-maintained legacy infrastructure. The combination of sensitive data residing on legacy systems and limited budgets to modernise them creates conditions that threat actors can easily exploit.
Security, visibility, and control built into the network
These challenges highlight how security has too often been treated as an add-on rather than a core design principle. Legacy migration and modernisation have been priorities for public sector organisations for several years, given the direct and significant impact of modern technology on service delivery, security and public satisfaction. That said, the sector’s historical aversion to early technology adoption, which is rooted in the need to minimise risk and control costs, has often led to delays in IT modernisation. Ironically, instead of mitigating risk, this hesitancy can introduce greater and more systemic vulnerabilities.
For example, outdated systems lack the security controls or capabilities of modern solutions, which limits support for new initiatives – from digital services to public-facing Wi-Fi – and reduces visibility into who or what has access to the network, leaving organisations more exposed to today’s advanced threats and AI-driven attacks.
For these teams, security can’t be an afterthought. Fragmented tools, limited visibility and manual processes increase risk and make it harder to respond to threats in real time. But by embedding security into the network itself, rather than layering it on top, IT teams can reduce complexity while delivering the reliability and resilience that mission-critical public services demand.
Increasingly, more organisations are turning to AI-powered platforms that unify networking, security and automation in a single environment. This simplifies management, improves visibility and enables faster detection and response. It also gives public sector organizations a starting place for implementing Zero Trust policies across their departments. With that unified view, IT teams can act quickly, stay ahead of incidents and ease operational strain.
As threats grow in frequency and sophistication, maintaining visibility, control and oversight of the network becomes essential. Simplifying operations and consolidating network and security management gives IT teams the insight they need to detect and the ability to act immediately when something looks wrong.
Building secure digital services at scale
Governments around the world are also investing in digital services that improve how people access information and engage with public institutions. From online portals and smart city initiatives to connected healthcare and education platforms, expectations are rising fast. Delivering these services securely requires a network that can scale, adapt and protect sensitive data, without adding unnecessary operational burden.
Real-world examples show how public sector organisations are modernising their networks to meet growing demand. For example, many cities and local governments face the challenge of securely connecting large numbers of residents while supporting a wide range of digital services. To address this, cities are building network infrastructure designed to deliver secure public Wi-Fi, reduce network complexity, increase visibility and protect confidential public and government data.
The result is a more secure, visible and manageable network capable of supporting services ranging from life-saving medical devices for the elderly to mobile learning tools for students – while maintaining strong security controls throughout.
Public sector IT decisions carry significant responsibility. Trust, resilience and continuity of public services all depend on the strength of the underlying network. By embedding security, visibility and control into the network from the outset, public sector IT leaders are better placed to reduce risk, maintain compliance and deliver the reliable, resilient digital services that the public and communities depend on.
