How to Prepare for a Cyber Essentials Plus Audit
Achieving Cyber Essentials Plus certification is a significant step toward demonstrating strong cybersecurity practices. While the standard Cyber Essentials certification involves a self-assessment, Cyber Essentials Plus requires an in-depth technical audit by a qualified assessor. The process verifies that your business is not only following best practices but also actively enforcing them. Preparing for this audit may seem daunting, but with the right approach, your business can pass with confidence. This guide explains exactly how to prepare for a Cyber Essentials Plus audit.
Understand the Difference Between Cyber Essentials and Cyber Essentials Plus
Before preparing for Cyber Essentials Plus, it’s essential to understand how it differs from the basic Cyber Essentials certification. The standard Cyber Essentials is a self-assessment covering five areas: firewalls, secure configuration, user access control, malware protection, and patch management. Cyber Essentials Plus, however, involves a hands-on technical assessment conducted by an external auditor who tests your systems for real-world vulnerabilities.
To qualify for Cyber Essentials Plus, you must first hold a valid Cyber Essentials certificate. The Cyber Essentials Plus audit must take place within three months of receiving the basic certification.
Review the Five Key Security Controls
The Cyber Essentials Plus audit focuses on verifying the following five controls:
- Firewalls – Ensure that your network is protected by properly configured firewalls. This includes router settings for remote workers.
- Secure Configuration – Disable unused services, change default settings, and use secure configurations across all devices.
- User Access Control – Apply the principle of least privilege. Each user should have access only to what they need.
- Malware Protection – Use reputable anti-malware software on all systems. Ensure real-time scanning is enabled and functional.
- Patch Management – Regularly update all software and operating systems. All critical patches should be applied within 14 days of release.
Auditors will test these areas during the Cyber Essentials Plus audit, so ensure everything is fully compliant beforehand.
Perform an Internal Pre-Audit Check
Before booking your Cyber Essentials Plus audit, conduct an internal pre-audit or gap analysis. This process can help uncover weaknesses or missing controls. Use the official Cyber Essentials documentation and work with your IT team or external consultants to test your systems. Many organizations simulate an audit internally by checking firewall configurations, running vulnerability scans, and reviewing user permissions.
Prepare a Representative Sample of Devices
During the Cyber Essentials Plus audit, the assessor will test a sample of your in-scope devices, typically including desktops, laptops, and mobile devices. Ensure that all these devices are:
- Running up-to-date operating systems and software
- Protected by functioning antivirus or anti-malware tools
- Properly configured with secure settings
- Not using unsupported or end-of-life software
If your team uses remote work setups, include VPNs and home routers in your review.
Educate and Involve Staff
Human error is a common source of security risk. Make sure your staff understands the importance of Cyber Essentials and follows best practices. Simple steps like avoiding weak passwords, reporting suspicious emails, and locking devices when unattended can go a long way. Some assessors may ask staff to demonstrate how systems are used, so training can impact the audit outcome.
Work With an Experienced Certification Body
Choose an accredited Cyber Essentials Plus certification body with a good track record. An experienced provider will guide you through the audit process, explain expectations, and offer pre-audit advice if needed. While the audit is technical, your assessor should work with you to make the process smooth and clear.
Conclusion
Preparing for a Cyber Essentials Plus audit doesn’t have to be overwhelming. By understanding the key requirements, performing a thorough internal check, updating your systems, and educating your team, you can confidently meet the standards of this rigorous certification. Remember, Cyber Essentials is more than a badge—it’s a practical framework that protects your business from real threats. Taking the time to prepare thoroughly for your Cyber Essentials Plus audit will strengthen your cybersecurity, impress your clients, and set your business apart as a trusted, security-conscious organization.
