Licensed IASME Certification Body

Cyber Essentials Plus certification

Independent technical testing that proves your Cyber Essentials controls work in practice, not just on paper. We carry out the audit ourselves and issue your certificate directly, so there is no hand-off to a third party.

Pricing

Published, by organisation size.

New applicants take both certifications. If you already hold a recent Cyber Essentials certificate, you may only need the audit.

The Plus audit must be completed within three months of your Cyber Essentials certification. Larger estates are scoped before quoting, and the Cyber Essentials fee itself is set by IASME and is the same at every certification body. Full detail is in the Cyber Essentials cost guide.

Why organisations need it

When declared is not enough.

Cyber Essentials shows you have answered the questions honestly. Cyber Essentials Plus shows an independent assessor has checked that the answers are true.

Contracts and tenders

Evidence, not description.

Public sector and supply chain contracts increasingly ask for Plus rather than the base certificate.

Defence supply chains

Required from Level 2.

Defence Cyber Certification requires Plus from Level 2 upwards, so plan both certifications together. DEFCON 658 explained

Customers and insurers

One line answers it.

When a supplier assessment or an insurer asks how you know your controls work, an independently tested certificate is the answer.

Your own assurance

Know, rather than believe.

Confidence that patching, malware protection and access controls work across the whole estate, not just on paper.

What the audit checks

The five controls, tested on your systems.

The assessor tests a representative sample of your devices and services against the current Cyber Essentials Plus test specification.

CheckWhat it confirms
External testingYour internet-facing systems do not expose vulnerabilities or unnecessary services
Device patchingHigh and critical security updates are applied within the required timescales
Malware protectionProtection detects and blocks test files delivered by email and through the web browser
Account controlsUsers do not hold unnecessary administrative rights, and administrator accounts are separate
Multi-factor authenticationCloud services in scope enforce multi-factor authentication as declared

Cyber Essentials Plus is not a penetration test. It verifies the five controls rather than looking for every possible way into your business. If you need an application or infrastructure tested in depth, that is penetration testing, and we explain the difference in Cyber Essentials Plus vs penetration testing.

What changed in April 2026

Two changes worth knowing before you book.

01

Your answers are locked

Your Cyber Essentials self-assessment must be final before Plus testing begins, and it cannot be changed afterwards. Accurate answers before booking matter more than ever.

02

Patching is checked twice

If testing finds missing updates, the assessor retests the failed devices and also checks a second random sample. The same vulnerabilities in both fail Plus and revoke Cyber Essentials, so patching has to be routine, not a pre-audit catch-up.

What happens on the day and how to prepare

How it works

From first conversation to certificate.

01

Scope and timing

We confirm your Cyber Essentials certificate date, your scope and the devices the sample will be drawn from, so you know how much time you have.

02

Preparation

You get a clear list of what to have ready: access, the right people available, and the controls the audit will check.

03

The audit

Remote as standard, on site anywhere in the UK where that suits the environment or your preference better.

04

Your certificate

Issued directly by us when you pass. If something needs fixing, we tell you exactly what and why, then retest under the current rules.

Who carries out your audit

Assessed by people who test for a living.

Every Cyber Essentials Plus audit is carried out by a qualified Malwise assessor, working directly for the certification body that issues your certificate. Nothing is subcontracted or passed to a third party.

Our assessors combine certification work with hands-on security testing experience. That matters on the day: an assessor who tests for a living understands what the checks are really looking for, and can explain a finding in terms your team can act on.

About Malwise

Can I get Cyber Essentials Plus without Cyber Essentials?

No. Plus builds on a current Cyber Essentials certificate and must be completed within three months of it. New applicants take both, using the combined prices above.

Is the audit remote or on site?

Remote as standard, with on-site attendance where the environment or your preference makes it more practical. We work across the UK.

What happens if something fails?

We tell you exactly what failed and why. You fix it and we retest. For patching failures, the April 2026 rules add a second random sample, which is why keeping the whole estate patched routinely matters.

How long does it take?

Mostly as long as preparation takes. Once access is arranged, the audit itself is a small part of the process. Our timescale guide covers planning around a deadline.

Do you carry out the remediation?

Usually your own team or IT provider makes the changes, since they know the estate. We tell you precisely what is needed, and can help where you want it.
