UK government-backed cyber baseline

Cyber Essentials, explained simply

The fastest way to prove cyber basics in the UK.

In a nutshell

Cyber Essentials is a UK government scheme covering five technical controls that block around 80% of common cyber attacks. Cyber Essentials Plus adds a hands-on technical audit.

The case for action

Why your organisation needs Cyber Essentials

Wins contracts, lowers insurance premiums, and provides a basic but real security uplift. Certification takes weeks, not months.

The upside

What your organisation gains

Unlock UK central government and MOD contracts that require it.

Lower cyber-insurance premiums and qualify for free liability cover.

Block around 80% of common internet-borne attacks.

Signal trust to enterprise buyers in weeks, not months.

Scope

Who it covers — and where

Who it applies to

Any UK organisation. Often mandatory for central government contracts and increasingly demanded by enterprise buyers.

Where it applies

United Kingdom — but recognised internationally as a trusted baseline.

Timing

When you need to act

Certification is valid for 12 months and must be renewed annually.

The path forward

Your roadmap to compliance

A practical journey — not a bureaucratic checklist. Tackle these stages in order and you'll move from "we should look into this" to ready.

  1. 1

    Scope what's in (whole organisation is recommended).

  2. 2

    Implement the five controls: firewalls, secure configuration, user access control, malware protection, security update management.

  3. 3

    Complete the IASME self-assessment questionnaire.

  4. 4

    Submit for review by a Cyber Essentials assessor.

  5. 5

    For CE Plus, book an on-site/remote technical audit within 3 months.

Reality check

Common struggles (and how to fix them)

The struggle

BYOD and home devices break the scope.

The fix

Use a clear acceptable use policy or supply company devices for in-scope users.

The struggle

Unsupported software in the estate.

The fix

Run an inventory before applying — replace or segregate end-of-life software.
