Government Cyber Action Plan

The Government Cyber Action Plan, published 6 January 2026, is designed to fulfil the objective outlined in the Digital and AI Roadmap: ensuring that public services are secure, trustworthy, and resilient.
It acknowledges that the ambition in the 2022 Government Cyber Security Strategy (GCSS), for all government departments to be resilient to known vulnerabilities and attack methods by 2030, is not achievable on the original timeline. It therefore proposes a more centralised, measurable, and directive model led by Department for Science, Innovation and Technology (DSIT).
What is most significant (and different) is not simply “more cyber activity”; it is the shift in operating model:
- Cyber risk will be treated as a system-wide governance problem, rather than an isolated department issue. This will be supported by a named government-wide risk owner, a new Government Technology Risk Group, and clearer escalation and mandated routes.
- Data, metrics, and assurance are prioritised, building on GovAssure and outcomes-based measurement (including use of Cyber Assessment Frameworks) with implementation milestones.
- The plan is overt about the drivers of risk, including legacy technology, control maturity gaps (asset management, protective monitoring, response planning), and common dependencies/suppliers. It positions shared services and coordinated response as key countermeasures.
From an industry perspective, the plan signals tighter expectations for suppliers and “defend as one” collaboration. There is also an increased focus on secure-by-design principles, shared detection content, and coordinated responses.
The main execution risks are predictable but material: data quality and reporting burden, the reality of skills shortages, and whether funding and delivery capacity are sufficient to reduce risk faster than threat and dependency complexity increases. The plan attempts to address capability constraints through a new Government Cyber Profession and centralised support/services, but delivery discipline will be decisive.
What is the UK Government Cyber Action Plan?
The Government Cyber Action Plan sets out a practical programme to strengthen the cyber security and digital resilience of public services, so citizens can rely on them for healthcare, benefits, tax, identity checks, and more. The headline is ambition; the substance is operational: this is a plan to measure risk, prioritise investment, raise accountability, and coordinate delivery at scale across government and the wider public sector.
This matters beyond Whitehall. If you supply government, regulate public services, operate critical national infrastructure, or lead cyber security in any organisation that depends on public-sector platforms and data flows, the plan signals a clear direction of travel: more measurable expectations, more assurance, more coordinated response, and stronger supply-chain governance.
Why Government felt it needed a new plan
The Action Plan is candid about the context. It links the push for digitised public services to the need for trust: as services move online, the “surface area” for cyber risk and operational failure grows. It also treats resilience failures broadly, covering malicious attacks and non-malicious outages, because both can remove access to critical services. The plan points to recent disruptions as evidence of impact. For example, it references the Synnovis incident affecting blood testing and surgeries, ransomware impacts on local authorities, the British Library ransomware attack, and the 2024 CrowdStrike outage, noting how a single supplier dependency can cause widespread disruption.
Most importantly, the government’s own assurance picture is uncomfortable. The plan states that GovAssure results showed “significant gaps” across departments, including low maturity in foundational controls such as asset management, protective monitoring, and response planning, and estimates that 28% of the technology estate is legacy technology and therefore highly vulnerable.
The “radical shift”: from aspiration to a more centralised operating model
A key line in the Action Plan is that the target in the 2022 Government Cyber Security Strategy, for government organisations to be resilient to known vulnerabilities and attack methods by 2030, is not achievable on the original timeline. The plan argues that a “radical shift” is needed, drawing on lessons from international and industry partners that strong central direction and active leadership can make a national-level impact.
In practical terms, that means a stronger centre, delivered through a new/expanded Government Cyber Unit within DSIT, led by the Government CISO, and including the Government Cyber Coordination Centre (GC3) (jointly sponsored with NCSC) to coordinate operational response to threats, vulnerabilities, and incidents.

The Operational Heart of the Plan
What CISOs and leaders should do now
Even if you are outside government, this plan provides a useful blueprint for how large, federated organisations can manage systemic cyber risk. For public sector CISOs, suppliers, and regulated operators, we recommend focusing on the next 90–180 days:
- Reconfirm risk ownership and board reporting. Ensure board-level cyber expertise is in place and reporting covers suppliers and critical dependencies, not only internal controls.
- Align your maturity narrative to CAF outcomes (where applicable). If you operate in or supply government-aligned sectors, expect CAF-aligned language to become more common in assurance and sponsorship conversations.
- Build an “evidence pack” for secure-by-design delivery. Be ready to show how you embed security and resilience in architecture and delivery, including monitoring and response readiness.
- Map your top risks to the plan’s “government-wide” patterns. Look hard at common vulnerabilities exploitable at scale, shared platforms, and supplier concentration risks.
- Refresh incident response and recovery assumptions. Assume concurrent incidents and complex recovery; validate supplier support arrangements; and exercise for realistic service disruption.
- Start PQC planning if you have long-lived cryptography dependencies. The plan signals a government-wide approach and roadmap for post-quantum migration, which will cascade into supplier roadmaps over time.
Where Talan can support
Talan works with public sector and critical service operators to turn plans like this into measurable delivery. Typical support aligned to the Action Plan includes:
- CAF-aligned maturity and resilience assessments and remediation roadmaps.
- Board-level risk appetite facilitation and reporting design.
- Secure-by-design governance and assurance for new digital services.
- Supply-chain cyber assurance (including strategic supplier dependency risk).
- Incident response exercising, recovery planning, and “lessons learned” operationalisation.
- Post-quantum cryptography (PQC) readiness and migration planning.
