Cyber Essentials & National Cyber Compliance in the United Kingdom

UK national cyber compliance covers the government-backed schemes organisations are increasingly required to meet: Cyber Essentials and Cyber Essentials Plus, the NCSC Cyber Assessment Framework (CAF), GovAssure for government departments, and the NIS Regulations 2018 for operators of essential services and digital service providers. CyberSigma provides readiness, remediation and assessment support across all of these. We are CERT-In empanelled and PCI QSA (CEMEA) authorised.

Meeting the UK's National Cyber Schemes

The UK government and the NCSC operate a layered set of cyber schemes. Cyber Essentials is now a baseline requirement for many public-sector and supply-chain contracts; the Cyber Assessment Framework (CAF) underpins NIS and GovAssure; and the NIS Regulations 2018 impose security and incident-reporting duties on operators of essential services and digital service providers.

CyberSigma helps UK organisations achieve and maintain these standards — from first-time Cyber Essentials certification to CAF-based assessments and NIS compliance — with practical, audit-ready support.

• Cyber Essentials self-assessment readiness and certification support.
• Cyber Essentials Plus hands-on technical audit preparation.
• NCSC Cyber Assessment Framework (CAF) assessments.
• GovAssure readiness for government departments and ALBs.
• NIS Regulations 2018 gap assessment and incident-reporting readiness.
• Supply-chain cyber assurance aligned to NCSC guidance.

What is Cyber Essentials and do we need it?

Cyber Essentials is an NCSC-backed scheme covering five core technical controls. It is increasingly required for public-sector contracts and supply chains, and is a strong baseline for any UK organisation. Cyber Essentials Plus adds an independent technical audit.

What is the NCSC Cyber Assessment Framework (CAF)?

The CAF is the NCSC's framework for assessing cyber resilience of essential functions. It underpins NIS compliance and GovAssure, and is used to measure outcome-based security maturity.

Who must comply with the NIS Regulations 2018?

Operators of essential services (energy, transport, health, water, digital infrastructure) and relevant digital service providers. They face security duties and incident-reporting obligations to their competent authority.

Can you take us from Cyber Essentials to ISO 27001?

Yes. We often help organisations start with Cyber Essentials and mature toward ISO 27001 and CAF/NIS, reusing evidence and controls to make each step efficient.
