Cyber Essentials Certification: Small Business Guide (2025)

What is Cyber Essentials?

Cyber Essentials is a UK Government-backed scheme that helps protect small businesses from common cyber threats. It focuses on five key security controls :

  1. Access control
  2. Secure configuration
  3. Patch management (updates)
  4. Malware protection
  5. Firewalls & internet gateways

By getting certified, you reduce risk, build customer trust, and often qualify for tenders and free cyber insurance (up to £25k) .

Why get certified?

  • Blocks up to 80% of common cyber-attacks
  • Builds trust with customers & partners
  • Often required for public sector contracts
  • May lower insurance costs
  • Gives peace of mind for business owners

What’s new in 2025?

  • Remote & hybrid work covered – all laptops, tablets, and mobiles must comply
  • Multi-factor authentication (MFA) – now mandatory
  • All endpoint devices included – not just servers
  • Fast patching – critical updates within 14 days
  • Work/personal account separation – keep business accounts secure
