Cyber Essentials is supported by the National Cyber Security Centre and recognised across the UK as a trusted cyber security standard. It demonstrates that your business meets essential security controls — reassuring clients, insurers and procurement teams that you take data protection seriously.
Cyber Essentials is designed to prevent around 80% of the most common, commodity-based cyber attacks. By implementing five essential technical controls — covering firewalls, access control, malware protection, secure configuration and patching — you dramatically reduce your exposure to phishing, ransomware and opportunistic breaches.
Many government contracts and larger supply chains now require Cyber Essentials certification as a minimum standard. Achieving CE positions your business as a secure, credible partner — helping you win work, build trust and stand out in competitive tenders.
Cyber Essentials is a UK Government-backed cyber security certification scheme designed to help organisations protect themselves against common online threats. It focuses on five key technical controls that reduce vulnerability to phishing, malware and ransomware attacks.
Any UK business handling client data, using email systems, cloud platforms such as Microsoft 365, or bidding for government and supply chain contracts should consider Cyber Essentials. Many public sector and defence contracts now require certification as a minimum standard.
Cyber Essentials (CE) involves a self-assessment questionnaire reviewed by a certification body. Cyber Essentials Plus (CE+) includes independent technical verification and vulnerability testing to confirm your controls are working in practice.
No certification can guarantee total protection. However, the UK Government estimates Cyber Essentials helps prevent around 80% of common, commodity-based cyber attacks, particularly those using automated scanning tools.
Cyber Essentials certification is valid for 12 months. Businesses must renew annually to maintain compliance and demonstrate continued adherence to security standards.
The base certification fee depends on business size, but total cost varies depending on remediation work required before submission. Many SMEs invest in a readiness assessment to ensure they pass first time.
Cyber Essentials is not yet legally mandatory for all businesses. However, it is required for certain UK Government contracts and is increasingly expected by insurers, larger clients and regulated supply chains.
The five technical controls are:
Firewalls
Secure configuration
User access control
Malware protection
Security update management (patching)
These controls form the baseline of cyber hygiene recommended by the National Cyber Security Centre.
Yes. Cyber Essentials was specifically designed for small and medium-sized enterprises (SMEs). Even businesses with fewer than 10 employees can achieve certification if they meet the required security standards.
Preparation we help you with typically includes:
Reviewing firewall and router configurations
Ensuring multi-factor authentication is enabled
Confirming devices are patched and up to date
Checking email security and DMARC configuration
Restricting administrative privileges
A structured gap analysis helps identify vulnerabilities before formal submission.
