Cyber Essentials, ready first time
We check your devices, accounts and network against the five Cyber Essentials controls, fix what would fail and support you through the assessment for Cyber Essentials and Cyber Essentials Plus.
What it is
The UK’s baseline for everyday cyber security
Cyber Essentials is a UK government-backed scheme, run with the National Cyber Security Centre (NCSC), that sets out five technical controls to protect organisations against the most common internet-based attacks.
IASME is the NCSC’s Cyber Essentials partner and licenses the certification bodies that carry out assessments. Certification is renewed every year, and the requirements are updated periodically, so we always prepare you against the version current at the time of your assessment.
- Asked for in many public-sector contracts and a growing number of private ones
- Covers your devices, servers, network and cloud services in scope
- Two levels: Cyber Essentials and Cyber Essentials Plus

The five controls
What an assessor will check
Every device, account and cloud service in scope has to meet all five. These are the areas we review and fix.
Firewalls
Boundary firewalls and the software firewalls on devices are configured so only the services you need are reachable from the internet, with default admin passwords changed.
Secure configuration
Unnecessary accounts and software removed, default passwords changed, auto-run disabled and devices set to lock, so systems are not left in their insecure factory state.
Security update management
Operating systems and applications are licensed, supported by the vendor and patched promptly. High-risk and critical updates must be applied within 14 days of release.
User access control
Everyone has their own account with only the access they need, admin rights are used only for admin tasks, and multi-factor authentication protects cloud services.
Malware protection
Anti-malware software or application allow-listing stops malicious code running on your devices, and is kept up to date.
Two levels
Cyber Essentials or Cyber Essentials Plus?
Both levels cover the same five controls. The difference is how they are verified. Many businesses start with Cyber Essentials and move to Plus when a customer or contract asks for it.

How we prepare you
From first call to certificate
You choose the certification body; we make sure there are no surprises when you get there.
Step 1: Scope and readiness check
We agree what is in scope, including laptops, phones, servers, cloud services and any personal devices that reach company data, then check each against the controls.
Step 2: Fix the gaps
We replace or isolate unsupported software, switch on multi-factor authentication, tighten firewall rules, remove unneeded admin rights and bring patching up to date.
Step 3: Questionnaire
We help you complete the self-assessment accurately, with the technical answers drafted for you to review and submit.
Step 4: CE Plus audit
For Plus, we run our own checks first, fix anything they find and are on hand while the assessor tests a sample of your devices.
Step 5: Stay compliant
Patching, device management and access reviews continue month to month, so next year’s renewal is a formality rather than a project.
Common gaps
What usually needs fixing first
Most small businesses are closer than they think. The same handful of issues comes up again and again in readiness checks, and most can be fixed without disrupting your team.
- Laptops or servers running an operating system that no longer gets security updates
- Cloud accounts, such as Microsoft 365, without multi-factor authentication for every user
- Staff using accounts with admin rights for everyday work
- Routers and firewalls with default passwords or old, open rules
- Updates applied irregularly rather than within the 14-day window
- Personal phones reaching company email with no basic controls
