Preparing your IT infrastructure for a Cyber Essentials audit means making sure your business's computer systems and networks meet a set of basic cybersecurity standards. These standards are designed to protect your organisation from common cyber threats such as hacking, phishing, and malware. For a UK small or medium-sized business, this preparation is essential not only to pass the audit but to reduce the risk of costly downtime, data breaches, and damage to your reputation.

Why Cyber Essentials matters for your business

Cyber attacks can lead to significant disruptions, including lost productivity, compromised customer data, and potential fines under UK GDPR and the Data Protection Act 2018. For example, if your servers are not properly secured, ransomware could lock you out of critical files, halting operations. Passing a Cyber Essentials audit demonstrates to customers, suppliers, and regulators that you take cybersecurity seriously, which can be a competitive advantage and a requirement for some contracts.

A typical scenario: SME preparing for Cyber Essentials

Consider a UK-based business with around 50 staff that relies on on-premise servers and cloud services. Their IT provider helps them review user access controls, ensuring only authorised employees can access sensitive systems. They implement multi-factor authentication (MFA) for remote access and confirm that all devices have up-to-date security patches. The provider also verifies that regular backups are performed and stored securely offsite. This preparation not only helped them pass the Cyber Essentials audit but also improved their overall resilience against cyber threats.

Practical checklist to prepare your IT infrastructure

• Review user access: Check who has access to your servers and critical systems. Remove or restrict accounts that are no longer needed or have excessive permissions.
• Implement multi-factor authentication (MFA): Ensure MFA is enabled for all remote and privileged access to your network and servers.
• Keep software up to date: Confirm that your operating systems, server software, and security tools receive regular updates and patches.
• Verify backup procedures: Check that backups are performed regularly, stored securely offsite or in the cloud, and that you can restore data quickly if needed.
• Secure your network perimeter: Use firewalls and ensure they are properly configured to block unauthorised access.
• Maintain device security: Ensure all devices connected to your network have antivirus software and are regularly scanned.
• Ask your IT provider: How do they manage patching and updates? What logging and monitoring do they have in place? Can they provide evidence of compliance with Cyber Essentials requirements?
• Check policies and documentation: Confirm that your business has clear cybersecurity policies, including password management and incident response plans.
