Cyber Essentials Plus Certification

Cyber Essentials Plus is the advanced tier of the UK government's Cyber Essentials scheme, adding an independent technical audit to the self-assessment. While Cyber Essentials demonstrates that you have implemented basic security controls, Cyber Essentials Plus provides independent verification that those controls are actually working — tested by a certified assessor who attempts to breach your systems using common techniques. For UK businesses bidding for government contracts, handling sensitive data, or wanting to demonstrate the highest level of security commitment, Cyber Essentials Plus is increasingly essential. We help businesses across London and the UK achieve Cyber Essentials Plus certification — from gap assessment and remediation through to the technical audit. Most businesses achieve certification within 4–8 weeks.

The short answer

Cyber Essentials Plus is the advanced tier of the UK government's Cyber Essentials certification scheme. It includes all the requirements of Cyber Essentials (five basic technical controls: firewalls, secure configuration, user access control, malware protection, patch management) plus an independent technical audit. A certified assessor visits your premises and tests your systems to verify the controls are properly implemented — attempting to breach your network, send phishing emails, and exploit common vulnerabilities. Certification is valid for 12 months.

Conduct a thorough gap assessment before applying — identify and fix all issues before the audit.
Test your controls internally before the assessor arrives — try to breach your own systems.
Ensure all devices are patched and up to date — the assessor will check for known vulnerabilities.
Verify that multi-factor authentication is enabled for all user accounts, especially administrators.

Understanding Cyber Essentials Plus Certification

Cyber Essentials Plus is the advanced tier of the UK government's Cyber Essentials certification scheme. It includes all the requirements of Cyber Essentials (five basic technical controls: firewalls, secure configuration, user access control, malware protection, patch management) plus an independent technical audit. A certified assessor visits your premises and tests your systems to verify the controls are properly implemented — attempting to breach your network, send phishing emails, and exploit common vulnerabilities. Certification is valid for 12 months.

Why It Matters

The business impact

Cyber Essentials Plus provides independent verification that your security controls actually work — not just that you say they do. This is increasingly required for government contracts, especially those involving sensitive data or higher value. Many private sector organisations also require Cyber Essentials Plus for their suppliers. Beyond contract requirements, the independent audit identifies real security gaps that self-assessment might miss, making your business genuinely more secure.

Who needs this?

Businesses bidding for government contracts that require Cyber Essentials Plus (especially higher-value or sensitive contracts). Businesses whose clients require independent security verification. Businesses that want to demonstrate the highest level of security commitment. Businesses that handle sensitive data and want independent assurance that their controls are working. Businesses that have achieved Cyber Essentials and want to take the next step.

Who doesn't need this?

Businesses that only need basic Cyber Essentials for their contracts may not need Cyber Essentials Plus. Businesses with very low risk profiles that don't handle sensitive data may find Cyber Essentials sufficient. However, the independent audit provides valuable assurance that self-assessment cannot, so we recommend Plus for most businesses that can afford it.

How It Works

The technical overview

Cyber Essentials Plus certification involves first achieving Cyber Essentials (self-assessment), then undergoing an independent technical audit. A certified assessor visits your premises and tests your systems — attempting to breach your network, send phishing emails, exploit unpatched vulnerabilities, and access systems with unauthorised credentials. The assessor verifies that all five Cyber Essentials controls are properly implemented. We guide you through the entire process — gap assessment, remediation, self-assessment, audit preparation, and audit support.
