Protect the services citizens depend on.

Councils, government bodies and public services hold sensitive data and run services people cannot do without. We help you defend them on public sector budgets and timescales.

The threat picture

Why attackers target government & public sector

Public bodies face the same criminal groups as private companies, plus state backed actors interested in policy, procurement and citizen data. Legacy systems, shared services and complex supply chains make it harder to see where the real risk sits.

Cybergen helps public sector organisations prioritise, test and monitor the systems that matter most, prepare for incidents and evidence progress against government frameworks.

01

Ransomware Against Public Services

Attacks on councils and public bodies can take services offline for weeks and expose large volumes of personal data. Recovery often costs far more than prevention would have.

02

Nation-State Espionage

State linked groups target policy, procurement and research information. Their intrusions are designed to stay hidden for long periods.

03

Legacy Systems

Older line of business systems may be hard to patch or replace. They need compensating controls, segmentation and careful monitoring.

04

Shared Services and Suppliers

Outsourced IT, shared platforms and software suppliers connect many organisations together. One weak link can affect several bodies at once.

05

Assurance and Accountability

Leaders must show that cyber risk is understood and managed. Frameworks such as the CAF and GovAssure turn that expectation into evidence.

Regulation and standards

The rules you work under

The obligations that shape security in government & public sector, and how we help you meet them with evidence rather than paperwork.

GovAssure

Central government departments and their arm's length bodies assess themselves against the NCSC Cyber Assessment Framework, with independent review of the results.

Official guidance

Government Cyber Security Strategy

The strategy sets the aim for government organisations to be resilient to known vulnerabilities and attack methods, using the CAF as the common assessment framework.

Official guidance

UK GDPR

Public bodies process large volumes of personal and special category data and must protect it with appropriate security and report qualifying breaches to the ICO.

Official guidance

NIS2 Directive

Public administration entities fall within NIS2 in EU member states, bringing risk management and incident reporting duties.

Illustrative scenario

A Council Locked Out on Monday Morning

How a typical attack on government & public sector unfolds, step by step. Press play to watch it run.

  1. 1Initial Access

    An unpatched remote access appliance is exploited over a weekend using a publicly known vulnerability.

  2. 2Credential Theft

    The attacker harvests administrator credentials and spreads across file servers and backup systems.

  3. 3Data Theft

    Housing, benefits and social care records are copied out to a cloud storage account.

  4. 4Encryption

    Systems are encrypted early on Monday, stopping payments, case management and contact centre tools.

Where Cybergen breaks the chain

Vulnerability management closes the exposed appliance, MDR spots the weekend activity, protected backups make recovery possible and a rehearsed incident plan keeps priority services running.

Illustrative example, not a real incident.

Government & public sector FAQ

Your questions, answered

Can't see your question? Ask our team.

Can you help with GovAssure and the CAF?

Yes. We help organisations understand the CAF outcomes that apply to them, assess their current position and build an evidence led improvement plan.

Are you available through public sector frameworks?

Cybergen is a Crown Commercial Service supplier and listed on G-Cloud. Speak to us about the right route for your organisation.

How should we prioritise with limited budgets?

Start with the services that would hurt citizens most if they failed, then focus on the controls that stop the most common attacks: patching, MFA, backups and monitoring.

What should we do if we are attacked?

Follow your incident plan, preserve evidence, call your incident response provider and report to the relevant authorities. Our team can help immediately.
