If you’ve heard the term “Cyber Essentials” but aren’t sure whether it applies to you, you’re not alone. It’s one of the questions I get asked most often — and the honest answer is: it depends, but probably yes.
Here’s a plain-English guide to what Cyber Essentials actually is, who needs it, and what’s involved. No jargon. No sales pitch.
What is Cyber Essentials?
Cyber Essentials is a UK government-backed certification scheme that helps businesses protect themselves against the most common cyber attacks. It was introduced because the vast majority of successful cyber attacks — around 80% — exploit basic security weaknesses that are completely preventable.
The scheme covers five core areas:
- Firewalls — controlling what comes in and out of your network
- Secure configuration — making sure devices and software are set up safely
- User access control — limiting who can access what, and when
- Malware protection — keeping malicious software out
- Patch management — keeping software and devices up to date
There’s also a higher level called Cyber Essentials Plus, which involves a hands-on technical audit rather than a self-assessment. Most small businesses start with the standard Cyber Essentials.
Who actually needs it?
The short answer: more businesses than you’d think.
You almost certainly need it if:
- You bid for government contracts — it’s been a requirement for central government suppliers since 2014, and increasingly required further down the supply chain
- Your clients (especially larger ones or those in regulated sectors) are starting to ask about your security posture
- Your cyber insurance requires it — this is becoming increasingly common as insurers tighten their requirements
- You handle personal data and want to demonstrate good GDPR practice
You should seriously consider it if:
- You use Microsoft 365 for email, files and day-to-day work
- You have staff working remotely or on multiple devices
- You’ve had a security incident (or a near miss) and want to make sure it doesn’t happen again
- You want to give clients confidence that their data is safe with you
You can probably wait if:
- You’re a sole trader with minimal client data and no plans to bid for contracts — though even then, the discipline of going through the process is genuinely useful.
What does it actually involve?
The standard Cyber Essentials certification is a self-assessment questionnaire. You answer questions about how your IT is set up, submit it to a certifying body, and they assess it against the standard.
It’s not as scary as it sounds — but it does require your IT to be set up properly. Common issues we find when helping businesses prepare include:
- Multi-factor authentication (MFA) not switched on for all users
- Old staff accounts still active
- Devices not being patched and updated regularly
- Unsupported software still in use
- Overly permissive access — people having access to more than they need
Most of these are straightforward to fix. The questionnaire just forces you to actually check.
How long does it take?
For a small business that’s reasonably well set up, getting Cyber Essentials ready typically takes a few weeks. Larger or more complex organisations may take longer, particularly if there’s a lot of remediation needed first.
The certification itself (once you submit) is usually turned around within a few days.
How much does it cost?
The certification fee itself is currently around £300–£500 depending on the certifying body. That’s just the assessment — it doesn’t include any IT work needed to get your systems up to standard first.
If you need support getting ready (fixing the gaps, updating configurations, setting up MFA properly), that’s where a company like ours comes in. We help businesses get Cyber Essentials ready without the stress — and because we’re already looking after Microsoft 365 for most of our clients, it’s usually far less work than people expect.
Does it actually make a difference?
Yes — and not just on paper.
The five controls Cyber Essentials requires you to have in place genuinely block the most common attack types. You’re not going to be immune to every threat, but you’ll be a much harder target than businesses that haven’t done this work.
There’s also a reputational angle. More and more businesses — and their insurers — are asking their suppliers about security. Having Cyber Essentials certification is a simple, credible answer to that question.
What’s the first step?
The best starting point is understanding where you currently stand. That means looking at your Microsoft 365 configuration, your device setup, and your current security policies, and identifying any gaps before you attempt the certification.
We offer a free IT and Security Check — 30 minutes, plain English, no obligation. We’ll look at your setup and tell you honestly what needs addressing before you’d be ready for Cyber Essentials.
From there, we can either help you get everything in place, or point you in the right direction if you’d prefer to handle it yourselves.
