Cyber Security for Public Sector Organisations and Government Suppliers

UK public sector organisations and government suppliers face ransomware targeting legacy council infrastructure, strict procurement certification requirements, and aggressive ICO enforcement on citizen data breaches. Local councils, housing associations, ALBs, and blue light services must protect citizen data while maintaining service continuity. Government suppliers on G-Cloud, DOS, and Cyber Security Services 3 frameworks must hold CE+ and pass penetration testing to win contracts. Cyphere operates across government procurement frameworks delivering CREST accredited assessments.

  • CREST accredited penetration testing for council networks, GovTech platforms, and citizen portals
  • CE+ and ICA certification body for government contract eligibility
  • PSN IT Health Check, GovAssure readiness, Def Stan 05-138, and UK GDPR compliance

Why the Public Sector Needs Specialist Cyber Security

  • Local councils operate sprawling legacy networks often running 15+ year-old servers alongside modern cloud, creating security gaps standard tools cannot address
  • Government suppliers on G-Cloud, DOS, and Cyber Security Services 3 frameworks must hold CE+ and pass cloud penetration testing to win or retain contracts
  • Council ransomware attacks (Redcar and Cleveland, Hackney, Leicester precedents) encrypt housing, benefits, planning, and social care systems for months
  • Housing associations hold vast tenant PII, financial data, and safeguarding records under intense ICO and Housing Ombudsman pressure
  • ALBs are transitioning to GovAssure (NCSC CAF-based annual assessment) under strict government oversight
  • Defence supply chain tier 2/3 firms must comply with Def Stan 05-138 alongside CE+ for MOD contract eligibility

Frequently Asked Questions

What cyber threats most affect local government and public sector organisations?
Ransomware encrypting council housing, benefits, and social care systems causes months of service disruption. Supply chain pivot attacks targeting smaller suppliers to access wider public sector networks are also highly prevalent.
How do you secure government suppliers and GovTech platforms?
We deliver CREST accredited cloud penetration testing, SaaS assessments, and web application testing for platforms on G-Cloud, DOS, and Cyber Security Services 3 frameworks.
What measures protect citizen PII and housing association data?
We test citizen portals, housing management systems, and social care platforms for access control weaknesses. Assessments identify where tenant PII and safeguarding data could be exposed.
How does Cyphere help comply with GovAssure, PSN, and NCSC CAF?
We deliver PSN IT Health Check assessments and GovAssure readiness reviews with structured gap analysis, remediation guidance, and compliance reporting for government organisations.
Why is Cyber Essentials Plus mandatory for government suppliers?
CE+ is required by Crown Commercial Service before suppliers can win contracts on G-Cloud, DOS, and CSS3 frameworks. It proves baseline security and mitigates supply chain risk.
Can Cyphere help with Def Stan 05-138 for the MOD supply chain?
Yes, we help defence tier 2/3 firms map controls to Def Stan 05-138 alongside CE+ certification for MOD contract eligibility.
How do you protect councils during ransomware attacks on citizen services?
Our incident response planning covers council disruption scenarios including system isolation, evidence preservation, and prioritised recovery of citizen-facing systems alongside ICO reporting.
What training addresses phishing and BEC for council and housing staff?
Targeted phishing simulations covering BEC on council payments, grant interception, and procurement fraud. Training designed for high-turnover environments including temporary staff.
How often should public sector organisations conduct penetration testing?
Annual testing is the baseline for PSN and CE+ compliance. Infrastructure changes, cloud migrations, or new citizen service deployments should trigger immediate assessment.
What is IASME Cyber Assurance and how does it help the public sector?
ICA builds on Cyber Essentials controls to cover security, recovery, and continuity. As an authorised body, we help organisations demonstrate broader resilience to regulators and procurement teams.
What makes Cyphere's approach unique for public sector and local government?
We operate across government procurement frameworks and understand both council civic obligations and supplier commercial realities. Our CREST accredited assessments are aligned to PSN, GovAssure, and CCS requirements.
