Every organisation in the UK, whether small or large, is a target for cyberattacks. From phishing scams to ransomware infiltrations, the stakes are higher than ever—and that’s where the Cyber Essentials certification scheme comes in. Designed by the UK Government and overseen by the National Cyber Security Centre (NCSC), this scheme provides businesses with the tools and processes to defend against the most common threats.
But what’s the difference between Cyber Essentials and Cyber Essentials Plus? Think of it this way: Cyber Essentials is your first line of defence—a self-assessment that ensures you have the basics covered, like firewalls, secure configurations, and malware protection. Cyber Essentials Plus takes it further, validating those defences with an independent technical audit for higher assurance.
Importantly, you can’t skip straight to Cyber Essentials Plus—achieving Cyber Essentials is a prerequisite. This means the real value lies in understanding how Cyber Essentials Plus builds on the foundation of Cyber Essentials to protect your organisation against more complex risks, such as supply chain vulnerabilities and sophisticated ransomware attacks.
In this guide, we’ll break down:
- The requirements and processes involved in both certifications
- How Cyber Essentials Plus provides additional assurance through advanced testing
- Practical insights to help you decide if upgrading is the right choice for your organisation
By the end, you’ll understand not only the difference between Cyber Essentials and Cyber Essentials Plus but also how they can work together to strengthen your cybersecurity strategy.
What is Cyber Essentials?
At its core, Cyber Essentials is a UK Government-backed certification designed to help organisations protect themselves from the most common cyberattacks, including phishing, ransomware, and malware.
Overseen by the National Cyber Security Centre (NCSC) and delivered through accreditation bodies like IASME, it’s a straightforward and cost-effective way for businesses to strengthen their cybersecurity posture.
The certification revolves around five key technical controls:
- Firewalls and Internet Gateways: Ensures your network is protected from unauthorised access.
- Secure Configuration: Eliminates vulnerabilities by configuring systems securely.
- User Access Control: Restricts access to sensitive data based on role and necessity.
- Malware Protection: Protects systems from malicious software through antivirus tools and safe practices.
- Patch Management: Keeps software and devices updated to prevent exploitation of known vulnerabilities.
By implementing these controls, organisations can significantly reduce their risk of falling victim to cyberattacks. But what makes Cyber Essentials particularly appealing is its simplicity. It’s designed for businesses of all sizes, from local startups to large supply chain operators.
The Cyber Essentials Process
The path to certification is straightforward:
- Self-Assessment Questionnaire: Organisations answer questions about their cybersecurity practices.
- Verification by an Accredited Body: Once submitted, the questionnaire is reviewed by a certification body such as IASME.
- Certification Issued: Upon approval, your organisation becomes Cyber Essentials certified, providing peace of mind to clients, partners, and stakeholders.
Cyber Essentials is often the first step in a cybersecurity journey, offering both a baseline of protection and a pathway to more advanced certifications, like Cyber Essentials Plus.
What is Cyber Essentials Plus?
While Cyber Essentials lays the groundwork for good cybersecurity, Cyber Essentials Plus takes it a step further by offering a higher level of assurance. This enhanced certification includes the same five key controls as Cyber Essentials but adds independent verification through technical testing, ensuring that your systems are as secure as they should be.
How Cyber Essentials Plus Builds on Cyber Essentials
The main difference between the two certifications lies in the level of scrutiny. Unlike Cyber Essentials, which relies on self-assessment, Cyber Essentials Plus requires a hands-on technical audit conducted by an accredited body like IASME. This audit ensures that your cybersecurity controls are not just implemented but are also functioning effectively.
Key aspects of the Cyber Essentials Plus certification process include:
- Remote Vulnerability Assessment: Your IT systems are scanned for weaknesses, helping to identify vulnerabilities before they can be exploited.
- Authenticated Patch Testing: A deeper dive into your software to ensure updates and patches have been applied correctly.
- Malware Protection Verification: Independent tests on your end-user devices (EUDs) to confirm that antivirus and anti-malware solutions are robust.
- Simulated Attacks:
- Email-based: Tests whether your defences can block malware delivered via phishing emails.
- Web-based: Evaluates your systems against malware threats from malicious websites.
This independent testing provides businesses with an added layer of confidence, reassuring clients, stakeholders, and regulators that their cybersecurity measures are more than just a checkbox exercise.
Who Should Consider Cyber Essentials Plus?
While Cyber Essentials is an excellent starting point for small businesses or those new to cybersecurity, Cyber Essentials Plus is better suited for organisations that:
- Handle sensitive data, such as in healthcare, legal, or finance.
- Operate within high-risk supply chains where vulnerabilities could impact other businesses.
- Need to demonstrate a higher level of security to clients, particularly in regulated industries.
The process may require more time and investment than Cyber Essentials, but the enhanced level of assurance it offers is invaluable for businesses with greater exposure to cyber risks.
