Why Cyber Essentials – and why now?

Cyber threats are not only increasing - they're evolving.

As the UK prepares to introduce the Cyber Security & Resilience Bill, the spotlight is shifting from voluntary best practice to enforceable cyber standards. Against this backdrop, Cyber Essentials offers a clear, credible and cost-effective way for organisations to demonstrate that they take cyber security seriously.

For CIOs and CTOs – especially those outside regulated sectors – Cyber Essentials provides a structured starting point for building resilience without the overhead of enterprise-grade frameworks.

What is Cyber Essentials - and why does it matter?

Cyber Essentials is a government-backed scheme, developed by the National Cyber Security Centre (NCSC), that focuses on securing the basic elements of your IT estate. It requires organisations to implement and maintain five technical controls:

  1. Firewalls and internet gateways
  2. Secure configuration of systems
  3. Access control and user privileges
  4. Malware protection
  5. Patch management and software updates

These aren’t cutting-edge defences – and that’s exactly the point. They’re the non-negotiables, the baseline attackers assume you don’t have in place. Research from the NCSC suggests that up to 80% of cyber attacks could be prevented by implementing these basic controls.

In a world of ransomware-as-a-service, business email compromise, and supply chain breaches, Cyber Essentials won’t make you bulletproof – but it will make you a much harder target.

Why choose Cyber Essentials over other frameworks?

For many organisations, Cyber Essentials offers three key advantages over more complex standards like ISO 27001 or the NCSC’s Cyber Assessment Framework (CAF):

Cyber Essentials vs Cyber Essentials Plus: what's the difference?

Both levels assess the same five control areas – but they differ in rigour:

  • Cyber Essentials is a self-assessment verified by an independent body. It is suitable for organisations seeking to quickly demonstrate basic cyber hygiene.
  • Cyber Essentials Plus includes an external technical audit, which involves vulnerability scanning, testing of endpoint security and verification of policies in practice. It offers a higher level of assurance and is often required by larger clients or contracts involving sensitive data.

Not sure which is right for you? Ask these questions:

  • Do you process sensitive data or work with regulated clients (e.g. health, finance, government)?
  • Would a security breach have reputational or commercial fallout?
  • Are you part of a larger supply chain into regulated industries?

If the answer to any is yes, Cyber Essentials Plus is likely the better fit.

How to get started

Achieving Cyber Essentials isn’t just a checkbox – it’s a chance to level up your internal practices.  Here’s how to approach it:

  1. Conduct a baseline audit of your current controls:  Review your existing policies and technical measures against the five Cyber Essentials control areas. Look for common gaps – such as outdated software, unsecured admin accounts, or inconsistent patching.
  2. Document roles, responsibilities, and procedures:  Ensure your IT and governance teams understand who owns each area of compliance. Develop or update clear procedures for access management, software updates, and threat detection.
  3. Fix known issues before you begin assessment:  Address any obvious vulnerabilities – such as unsupported operating systems, lack of multi-factor authentication, or unmanaged mobile devices. These will likely lead to non-compliance if left unresolved.
  4. Ensure leadership engagement and internal communication:  Make sure executive stakeholders understand why certification matters and what it will demonstrate to clients, partners, and regulators. Keep staff informed of policy changes or new security expectations.

Many Managed Service Providers – including Roc – offer Cyber Essentials readiness packages – useful if you need to move quickly or lack internal resources.

Final thought: Taking a strategic step forwards

In today’s climate, doing nothing is riskier than ever – and with cyber due diligence becoming part of M&A, supply chain reviews and compliance audits, Cyber Essentials is a visible first move

It shows clients, stakeholders, and regulators that you’re taking cyber security seriously, and it provides a practical foundation to more advanced frameworks in the future.  For CIOs and CTOs seeking a high-impact yes practical path to improved resilience, Cyber Essentials is an ideal place to start – and an increasingly necessary one.
