Cyber Essentials Certification
Cyber Essentials is the UK government-backed cybersecurity certification scheme that helps businesses protect against the most common cyber attacks. It is increasingly required for public sector contracts, and many private sector clients now require their suppliers to hold certification. The scheme covers five key technical controls: firewalls, secure configuration, user access control, malware protection, and patch management. We help businesses across London and the UK achieve both Cyber Essentials and Cyber Essentials Plus certification — from initial gap assessment and remediation through to the technical audit. Most businesses achieve certification within 4–8 weeks, strengthening their security posture and opening doors to new contracts.
Cyber Essentials is a UK government-backed cybersecurity certification scheme that defines a set of basic technical controls to protect against common cyber attacks. The five controls are: boundary firewalls and internet gateways, secure configuration, user access control, malware protection, and security update management (patching). Cyber Essentials is a self-assessment certification; Cyber Essentials Plus adds an independent technical audit conducted by a certified assessor. Certification is valid for 12 months and must be renewed annually.

The business impact
Cyber Essentials is increasingly a prerequisite for winning contracts. The UK government requires it for certain public sector contracts, and many private sector organisations require their suppliers to hold certification. Beyond contract requirements, the five Cyber Essentials controls address the most common attack vectors — implementing them significantly reduces your risk of a successful cyber attack. Certification also demonstrates to clients, partners, and stakeholders that you take cybersecurity seriously.
Who needs this?
Businesses bidding for public sector contracts (Cyber Essentials is mandatory for many government contracts). Businesses whose clients require supplier cybersecurity certification. Businesses that want to demonstrate their commitment to cybersecurity. Businesses that need a baseline security standard to work towards. Any business that hasn't yet implemented the five basic Cyber Essentials controls.
Who doesn't need this?
Businesses that already hold a higher security certification (like ISO 27001) may not need Cyber Essentials, though many maintain both for contract requirements. Businesses with no external clients or contracts may choose to implement the controls without formal certification. However, the controls are best practice for all businesses, and certification is relatively inexpensive.
The technical overview
Cyber Essentials certification involves implementing the five technical controls and completing a self-assessment questionnaire, which is reviewed by a certification body. Cyber Essentials Plus adds an independent technical audit where a certified assessor tests your systems to verify the controls are properly implemented. We guide you through the entire process — gap assessment, remediation, self-assessment, audit preparation, and audit support — ensuring you achieve certification efficiently.

Expert recommendations
Conduct a gap assessment before applying — identify and fix issues before the audit rather than during.
Document your security policies and controls — the self-assessment requires evidence of implementation.
Implement all five controls properly — partial implementation will not pass the audit.
Use the certification process as a security improvement exercise, not just a box-ticking exercise.
Plan for annual renewal — certification expires after 12 months and must be maintained.
Consider Cyber Essentials Plus if clients require it or if you want independent verification of your security.
