How to build a Cyber Essentials asset register

Build a Cyber Essentials asset register that covers laptops, servers, mobiles, cloud services and admin accounts — and keep it accurate.

An accurate asset register is the foundation of Cyber Essentials evidence. Most other controls reference it.

This guide describes what to include and how to stop the register drifting after first certification.

List in-scope hardware

Capture every device that processes in-scope data or accesses in-scope services.

  • Laptops and desktops with owner and OS
  • Servers (on-prem and cloud)
  • Firewalls and routers
  • Mobiles in scope

List cloud services and SaaS

Cloud services are part of scope. Capture each platform, its admins and whether MFA is enforced.

Capture admin accounts separately

Admin accounts deserve their own list — they are over-represented in assessor questions.

Record scope decisions

Anything you exclude must have a documented reason. Future-you and your assessor both need it.

Maintain quarterly

Asset registers built once and forgotten are the single biggest evidence gap at renewal. Sweep at least quarterly.

Practical examples

Laptop row

Hostname, owner, OS, version, encryption status, joined date.

Cloud service row

Service name, owner, admins, MFA enforced (yes/no).

Admin account row

User, platform, account type, MFA method, last reviewed.

Common mistakes

  • Treating it as a one-off

    Registers built at first certification and never updated are usually wrong by renewal.

  • Skipping SaaS

    Forgetting accounting, CRM or design SaaS leaves obvious gaps.

  • Mixing admins with users

    Track admins separately — they need MFA evidence and are reviewed more often.
