Ransomware targeting essential services
Attacks that disrupt public-facing services, back-office systems, social care, benefits platforms, or emergency services operations.
Cyber Security for Government & Public Sector
Strengthening resilience for essential services, sensitive data, and citizen-facing systems across central, local, and public-sector organisations.
Cyber Defence for Government, Local Authorities & Public Services
Government and public-sector organisations operate under intense scrutiny and carry responsibility for essential services, citizen data, and national infrastructure. Cyber incidents can cause service outages, financial impact, data breaches, and long-lasting reputational harm.
Cyber Defence provides comprehensive support for central government bodies, councils, emergency services, regulators, and public-sector agencies. Our services strengthen security across cloud identity, legacy systems, OT, IoT, and citizen-facing technology.
Threats
Key cyber threats facing government & public services
Public-sector organisations face persistent threats from cybercriminals and nation-state actors seeking disruption, impact, or data theft:
Data breaches & citizen data exposure
Unauthorised access to sensitive records, case files, personal data, or regulatory information.
Cloud identity compromise
Misuse of Microsoft 365, Azure AD, and SaaS identity systems used across public-sector workplaces.
Attacks on OT, IoT & civic infrastructure
Attempts to compromise traffic control systems, CCTV networks, public building automation, sensors, and connected devices.
Phishing & credential harvesting
Campaigns targeting staff across departments, schools, social care, and emergency services.
Nation-state targeting and espionage
Advanced persistent threats focusing on disruption, reconnaissance, policy intelligence, or sensitive data theft.
