What is Cyber Essentials and how many businesses have it?

The short answer

Cyber Essentials is a UK government-backed scheme that checks five basic security controls. Few businesses hold it: 3% of UK businesses, and 21% of larger ones, in the government's 2025 survey. Only 12% of businesses had even heard of it.

What it checks

The scheme covers five controls that guard against the most common attacks:

  • Firewalls that guard your internet connection.
  • Safe settings on your devices and software.
  • Only the right people can get into each account.
  • Protection against harmful software.
  • Updates put on in good time.

How you get it

You answer a set of questions online about each of the five controls, and a certification body checks your answers. Cyber Essentials Plus adds a hands-on test by an assessor. You renew each year. Many firms first check themselves against the five controls, then fix the gaps before they apply.

Who needs it

Some public sector contracts ask suppliers to hold it. Even if no customer asks, the five controls make a good checklist for any business. Holding it also shows customers that you take the basics seriously.

Is Xevrion the same as being certified?

No. Xevrion's Security part shows how ready you are for each control and what is left to do. Readiness is a checklist, not a certificate, so it proves nothing to a customer. Only an IASME certification body can certify you.
