Rethinking Cyber Security as a Public Sector Value Proposition

In the traditional landscape of public sector IT, I’ve witnessed cyber security be treated as something of a ‘back-office’ function; a necessary cost centre focused on risk mitigation, regulatory compliance, and crisis management.

Long shrouded in technical mystique, cyber security services can feel distant to many and – with its language of risk registers, firewalls, and ISO standards – it’s too frequently siloed from broader policy, service delivery, and organisational strategy.

However, as governments pivot toward digital-first models, where new public services are being designed and built natively for digital platforms (think websites, apps, online portals), and where citizens increasingly expect seamless, trustworthy interactions online, this narrow view on security is no longer sufficient.

In this new paradigm, cyber security must be understood as foundational to public value. It’s about enabling trust, equity, resilience, and innovation in the way governments serve their people.

Thought of this way, cyber security (when done right!) is not a constraint, but an enabler.

Cyber security as a trust enabler

Trust is the essential foundation upon which all successful digital government services are built. As citizens we trust government portals with sensitive data constantly (health records, financial details, identity documents, etc.), and we do so with the assumption that our data is secure and handled with integrity.

Of course, the moment this trust is compromised, the very premise of digital service delivery is weakened. Take, the WannaCry ransomware attack in 2017. Though not targeted specifically at the NHS, the attack had a great impact upon the institution due to outdated systems and a lack of preparedness. The public was left wondering how such a critical organisation could be so vulnerable and, ultimately, the damage went beyond IT systems – it struck at the public’s confidence in the government’s ability to manage digital infrastructure safely. Incidents like these which expose vulnerable people or sensitive data are not merely IT failures; they are governance failures with deep human consequences.

In contrast, secure systems foster trust. Estonia’s widely lauded e-Government framework demonstrates how cyber security and digital services can evolve simultaneously. By embedding strong encryption, secure digital IDs, and blockchain-backed data access logs, Estonia has cultivated a digital society where citizens trust online services more than traditional, paper-based ones even.

In a digital public sector, trust is a form of currency, then. The more robust, transparent, and citizen-focused our cyber defences are, the more likely people are to engage with and embrace digital government services.

Proactive cyber security as a strategic asset

I see it a lot: cyber security being treated as a necessary control layered on top of systems and services after they’ve been built. The issue with this is that it’s inherently reactive – it leaves public bodies vulnerable to last-minute fixes, escalating technical debt, and reputational risk.

By contrast, a secure-by-design approach means that security is embedded into the foundations of systems and services from the outset. It’s not a checkpoint, but a guiding principle in architecture, design, procurement, and deployment.

In the public sector, secure-by-design means:

• Building digital services with security requirements as core features, not optional add-ons. 
• Implementing identity and access controls, encryption, and audit capabilities during the design stage, rather than bolting them on later. 
• Ensuring procurement processes favour vendors and solutions that meet baseline security standards, including compliance with frameworks like NCSC’s Cyber Assessment Framework or ISO/IEC 27001. 
• Using threat modelling early in the service lifecycle, so that likely attack paths are mitigated before code goes live. 

Secure-by-design systems are also more resilient, easier to maintain, and cheaper to secure because the architecture supports, rather than resists, protective measures. By minimising technical debt and late-stage remediation, organisations avoid expensive rework and reduce time-to-delivery for new services.

Consider the contrast: retrofitting security into an existing citizen benefits portal might require a full redesign of authentication workflows and back-end data stores, something that’s both costly and disruptive. If the same service had been built with secure APIs, identity verification, and encryption controls in mind from the beginning, those risks would have been mitigated as part of the build, not as a crisis response.

So, we see, secure-by-design isn’t just a technical philosophy it’s a strategic enabler of speed, scale, and safety. It allows public sector organisations to move quickly and confidently, knowing that their services are resilient by default, not just by defence.

Cyber security and equality

Sadly, the impact of cyber security (or its absence) is not felt equally across society.

Vulnerable populations, such as those reliant on social services, the elderly, or individuals with limited digital literacy, are disproportionately affected by cyber incidents.

A breach in a local authority’s housing system, for example, might expose the addresses of survivors of domestic violence. A compromised social care database could reveal deeply personal details about individuals in assisted living. For those already on the margins of society, such breaches are not just technical failures, they are breaches of dignity, safety, and trust.

In this context, cyber security becomes a matter of social justice inside the public sector. Ensuring the safe and equitable access to digital public services is the right thing to do in organisations that strive to be inclusive and that set clear equality objectives.

To this end, its worth noting that, as digital inclusion initiatives continue to expand access to online services, equal attention must be paid to securing these services.

Measuring cyber security as public value

Traditional cyber security metrics, such as incident counts, patching frequency, or mean time to detect, are undoubtedly important, but potentially insufficient on their own for the public sector. After all, what truly matters is how these security metrics translate into citizen outcomes and organisational resilience.

In my opinion, new KPIs should reflect a broader value proposition and include:

• Citizen confidence in digital services, measured through regular sentiment surveys, for example. 
• Uptake and sustained use of digital platforms, indicating trust and usability. 
• Service continuity and resilience scores, capturing how well systems respond to attacks or outages. 
• Inclusion metrics, ensuring that vulnerable groups are not left behind in the digital transformation. 

By evolving to include these dimensions, public sector performance frameworks make cyber security visible as both a technical achievement and a public value outcome. Here, cyber security reinforces the government’s role in safeguarding democratic processes and protecting sensitive data.

Policy recommendations

To unlock the full strategic value of cyber security in the public sector and to better reflect its role in delivering public good it might be helpful for decision-makers to consider the following priorities:

• Embedding cyber security into all digital transformation strategies: it must be treated as a core design principle, not a bolt-on or afterthought.
• Funding cyber security as core infrastructure: like roads, bridges, and utilities, digital security is essential to national functioning and should be funded accordingly.
• Foster public-private partnerships: the threat landscape is dynamic and borderless. Collaborating with industry for threat intelligence, innovation, and capacity-building will enhance national resilience.
• Standardise secure design frameworks across government: reusable patterns, open standards, and interoperability protocols can reduce duplication and uplift the baseline across agencies.
• Champion transparency and accountability: citizens deserve to know how their data is being protected. Regular public reporting on cyber security measures and incidents can build trust and drive improvement.

Final word

Let’s reshape cyber security so that it’s no longer just about preventing bad outcomes but enabling good ones.

Think of cyber security as the bedrock of digital public services, citizen trust, and national resilience. Decision-makers must reframe security spend not as a cost to be minimised, but as a public value proposition to be maximised.
