If you’re looking to protect your business from cyber threats, you’ve probably heard about Cyber Essentials. It’s a UK government-backed scheme designed to help organisations improve their cybersecurity. But what exactly are the different cyber essentials certification levels? And how do you know which one is right for you? This guide will break it down in simple terms. You’ll get clear answers, practical tips, and a better understanding of how to get certified quickly and confidently.
Understanding Cyber Essentials Certification Levels
Cyber Essentials has two main certification levels: Cyber Essentials and Cyber Essentials Plus. Both aim to protect your business from common cyber attacks, but they differ in how they verify your security measures.
Cyber Essentials is a self-assessment. You complete a questionnaire about your cybersecurity controls. An external certifying body reviews your answers and issues the certificate if you meet the requirements.
Cyber Essentials Plus is an independent technical audit. Experts test your systems to confirm that the answers you gave in your Cyber Essentials assessment are in place.
Choosing the right level depends on your business size, risk profile, and the contracts you want to win. For example, many government contracts require at least Cyber Essentials certification. Some sectors, like legal and financial organisations, may prefer the added assurance of Cyber Essentials Plus.

Why Cyber Essentials Matters for Your Business
Cyber attacks are on the rise. Small and medium-sized businesses are often targets because they may lack strong defences. Cyber Essentials helps you build a solid foundation to protect your data, systems, and reputation.
Here’s why it’s worth your time:
Reduce risk: Implementing Cyber Essentials controls cuts your risk of common cyber attacks by up to 80%.
Win contracts: Many UK government and private sector contracts require Cyber Essentials certification.
Build trust: Show customers and partners you take cybersecurity seriously.
Save money: Avoid costly breaches and downtime.
Getting certified is straightforward. You don’t need to be a tech expert. The process guides you through simple steps to secure your network, devices, and software.
What are the Cyber Essentials requirements?
To achieve Cyber Essentials certification, you must meet five key technical controls:
Secure your internet connection
Use firewalls and routers to protect your internet connection from unauthorised access.
Secure your devices and software
Keep all devices and software up to date with the latest security patches.
Control access to your data and services
Limit user access to only what they need. Use strong passwords and multi-factor authentication where possible.
Protect against viruses and malware
Install and maintain anti-virus software on all devices.
Keep your devices and software up to date
Regularly update your operating systems and applications to fix security vulnerabilities.
Meeting these requirements shows you have the basics covered. For Cyber Essentials Plus, an external assessor will test these controls on your systems to verify they work effectively.

How to Get Certified Quickly and Easily
Getting your Cyber Essentials certification doesn’t have to be complicated. Here’s a simple step-by-step approach:
Assess your current security
Review your systems against the five Cyber Essentials controls. Identify any gaps.
Fix any issues
Apply necessary updates, install firewalls, and strengthen passwords.
Complete the self-assessment questionnaire
Be honest and accurate. The questionnaire covers your security policies and technical controls.
Submit your application
Choose a certification body to review your answers. They will issue your certificate if you meet the standards.
Consider Cyber Essentials Plus
If you want extra assurance, arrange for an external technical audit.
If you’re unsure about any step, expert advice is available. Many providers offer support to help you prepare and submit your application smoothly.
For those who want to understand the nuances of certification, you might come across terms like Cyber Essentials Marking Only. This refers to a certification option where your organisation is marked as compliant based on documentation and self-assessment and is an unsupported service. Cyber Essentials Plus will never be unsupported since a Cyber Security Expert needs to physically access your systems and devices in order to perform the audit.
Tips to Maintain Your Cyber Essentials Certification
Certification is not a one-time event. Cybersecurity is an ongoing effort. Here’s how to keep your certification valid and your business safe:
Regularly update software and devices
Cyber threats evolve. Stay ahead by applying patches and updates promptly.
Train your staff
Human error is a common cause of breaches. Educate your team on phishing, password hygiene, and safe internet use.
Review access controls
Periodically check who has access to sensitive data and systems. Remove unnecessary permissions.
Monitor your network
Use tools to detect unusual activity early.
Plan for re-certification
Cyber Essentials certificates last 12 months. Start preparing early for renewal.
By following these steps, you’ll not only keep your certification but also strengthen your overall security posture.
Taking the Next Step in Cyber Security
Now that you understand the cyber essentials certification levels, you’re better equipped to protect your business. Whether you choose Cyber Essentials or Cyber Essentials Plus, certification is a smart investment. It reduces risk, builds trust, and opens doors to new opportunities.
