Security infrastructure for public sector.
Secure by Design foundations, accredited platforms, and managed operations calibrated to the assurance profile. Built to be examined by NCSC, NAO, or Select Committee.
Overview
Security infrastructure infrastructure for public sector, built to the standard institutions in this sector are required to operate.
XVICA designs, builds, and operates this layer for public sector clients in the UK, US, Canada, and Australia. The work is specified against the regulatory regime, the operational profile, and the examination expectations of this sector before any code is written.
What public sector cannot get wrong here.
- A state-sponsored incident is a national-level event before it is a technical one.
- NCSC assurance expectations rise each year.
- Supply-chain attacks on public-sector suppliers are now a standing concern.
- Public-sector incidents are reported in public, often while they are still being handled.
Named regimes, mapped controls
Regulatory requirements are translated into explicit control requirements, then mapped to tests and evidence collection. Nothing is implied.
UK government frameworks
Secure by Design, Government Functional Standard for Security (GovS 007), NCSC guidance, Cyber Assessment Framework, and departmental accreditation.
Classification handling
OFFICIAL and OFFICIAL-SENSITIVE by default. Classified handling via accredited infrastructure and vetted personnel on a case-by-case basis.
Supplier & supply chain
Cyber Essentials Plus for supplier assurance, Technology Services 3 / Digital Outcomes assurance, and NCSC supply-chain guidance.
Design decisions distinctive to this intersection
Components and design choices that recur across our work for this sector. Each deployment is specified individually.
Secure by Design evidence
Principles mapped to concrete controls and to measurable control effectiveness. Not a slide deck.
CAF-aligned operating model
Cyber Assessment Framework outcomes mapped to operational practice and evidence streams.
Supply-chain scrutiny
Every supplier dependency mapped, assessed, and monitored. Substitution paths identified before concentration becomes acute.
Incident communications
Runbooks include public communications and Ministerial briefing templates. An incident does not become a comms crisis by surprise.
Accredited environments
Where classification requires it, the platform is deployed on accredited infrastructure under the appropriate handling regime.
How we work in public sector.
Public-sector security operates under a constraint private-sector work rarely has: an incident becomes a public event, sometimes while it is still being contained, and the evidence of the response will be reviewed by NCSC, NAO, and — in significant cases — the media. We build with that reality shaping the operating model rather than treating it as a PR overlay. Runbooks include the communications track alongside the technical one; control evidence is maintained continuously so that the post-incident report is a query rather than a reconstruction; supplier dependencies are mapped and monitored so concentration risk is visible before it becomes an incident's root cause. The outcome departments describe afterwards is that incidents are contained faster and communicated better, which is the part of security the public actually observes.
How engagements run
Three canonical commercial models. The right one depends on your in-house capability roadmap and risk appetite.
License and operate a ready platform
Deploy an XVICA-developed platform configured for your environment. Optional managed operations under SLA.
Partnership modelCo-Build + OperateLong-term joint build
XVICA leads engineering; your team provides domain ownership and governance. Outcome-based commercial structure.
Partnership modelBuild-Operate-TransferBuild it, run it, hand it over
Designed, built, and operated to a specified maturity threshold, then transferred with documentation and runbooks.
Partnership modelSecurity infrastructure elsewhere
The same engineering discipline applied to neighbouring industries. Regulatory regime and operating profile differ; the standard does not.
Security for financial institutions
Zero-trust foundations, DORA-aligned operating model, rehearsed incident response — built for institutions that get examined every year.
Read onSecurity for enterprise
Zero-trust across hybrid estates, detection engineering as code, and managed security operations when the internal team is the right size for normal days, not incidents.
Read onSecurity for healthcare
Clinical-safety aware security foundations. Zero-trust, evidenced controls, and operations that understand that a locked-out clinician is a patient-safety event.
