Why Once-a-Year Cyber Essentials Isn't Enough: The Case for Continuous Assessment

Written by Louise Ralston | Nov 10, 2026

Getting your Cyber Essentials certificate is a great moment. You've done the work, you've passed, and you've got the badge to prove it. But here's the bit nobody likes to say out loud: your certificate shows how secure you were on one day. Attackers don't work to your renewal date.

In this blog, we'll look at what changes in your business over 12 months, what the NCSC and UK government say about it, and why continuous assessment is the simplest way to stay compliant, stay secure and make next year's renewal painless.

A lot can change in 12 months

The day after you pass, your business carries on, and so does your IT. Over a year, it's completely normal for:

  • A steady stream of security updates to be released for your operating systems, browsers and apps
  • New laptops, phones and servers to join the network
  • Staff to install new software, or keep using old versions they've grown attached to
  • Software to reach end of life and stop getting security fixes
  • New vulnerabilities to be found in products you already use

Any one of these can quietly take you out of compliance. Under Cyber Essentials, critical and high-risk security updates must be applied within 14 days of release (IASME). Miss one in March and you may not find out until your renewal, or until someone else finds it first.

What the NCSC and UK government say

The official guidance is clear. The NCSC says organisations should carry out vulnerability assessments across their entire estate at least every month (NCSC). Not once a year. Every month.

And the threat is real. The UK government's Cyber Security Breaches Survey 2025/26 found (GOV.UK):

  • 43% of UK businesses identified a cyber breach or attack in the last 12 months, around 612,000 businesses
  • That rises to 65% of medium businesses and 69% of large businesses
  • Only 18% of businesses had carried out a cyber security vulnerability audit
  • Only 24% of businesses had controls in all five Cyber Essentials areas

The good news? Cyber Essentials works. The NCSC reports that organisations with Cyber Essentials are 92% less likely to make a cyber insurance claim (NCSC). Continuous assessment is how you keep that protection working every day of the year, not just on assessment day.

What is continuous assessment?

Continuous assessment means checking your systems regularly, usually monthly, rather than once a year at renewal. In practice, it's a monthly vulnerability scan of your devices that looks for the things Cyber Essentials Plus and IASME Cyber Assurance care about: missing patches, outdated software and unsupported versions.

Each month you get a report with a prioritised fix list, so you know exactly what needs doing and in what order. You fix it, the next scan confirms it, and your compliance stays live all year.

Think of it like an MOT versus regular servicing. The MOT tells you whether the car passed on the day. Servicing keeps it roadworthy for the other 364.

 

Why continuous assessment helps your business

You stay compliant all year, not just on assessment day. Monthly scans pick up missed updates and unsupported software while they're still small fixes, not renewal-day panics.

You pass first time. When you've been fixing issues every month, your Cyber Essentials Plus or IASME Cyber Assurance assessment becomes a formality rather than a scramble.

You reduce the risk of a breach. As the NCSC points out, regular scanning shows you which risks exist and reveals when updates aren't being installed. Finding and fixing them quickly shrinks the window an attacker has to use them.

You build evidence of due diligence. A history of monthly scans shows customers, insurers and regulators that you take security seriously, and can support you if you ever face an investigation or a claim.

You win more tenders. Buyers increasingly want proof that a supplier stays secure, not just that they passed once. A record of continuous assessment answers that question.

You spread the effort, and the cost. Small monthly fixes are easier to manage than one big annual push. With CTS, you can also add next year's certification and spread the cost over 12 months.

You may not need a pen test (yet). For many organisations, regular vulnerability assessment covers what they need. For others, it shows exactly where a pen test would add value, so you don't pay for one blind.

 

Getting Started with Cyber Tec

At Cyber Tec Security, we're the certification people. As an IASME Authorised Certification Body, we certify organisations against Cyber Essentials, Cyber Essentials Plus, IASME Cyber Assurance and Defence Cyber Certification (DCC). And we don't think certification should stop at the certificate.

Our monthly Vulnerability Assessments give you:

  • Monthly scans across your Windows, Linux and macOS devices
  • A detailed report each month with a prioritised fix list
  • Remedial guidance from a CTS security professional
  • Scanning powered by one of the few tools approved by the NCSC as a Cyber Essentials Plus assessor tool
  • No pre-assessment needed, so you can start straight away
  • The option to add next year's certification and spread the cost over 12 months

You can choose monthly scans for continuous compliance, or a one-off annual assessment ahead of your Cyber Essentials Plus or IASME Cyber Assurance renewal.

Frequently asked questions

Isn't my Cyber Essentials certificate valid for 12 months?

Yes, your certificate is valid for 12 months. But it reflects your security at the time you were assessed. You're expected to keep meeting the requirements, such as applying critical and high-risk updates within 14 days, throughout the year.

How often should we carry out vulnerability assessments?

The NCSC recommends vulnerability assessments across your whole estate at least every month. More mature organisations, especially those with internet-facing services, may scan more often.

What's the difference between a vulnerability assessment and a penetration test?

A vulnerability assessment scans your systems for known weaknesses, such as missing patches and outdated software, and gives you a prioritised fix list. A penetration test is a deeper, manual exercise where a tester tries to exploit weaknesses. Many organisations find regular vulnerability assessments cover what they need, and they help you see where a pen test would add value.

Will continuous assessment help us pass Cyber Essentials Plus?

Yes. If you're finding and fixing issues every month, there's far less to put right before your assessment, which makes a first-time pass much more likely.

Does continuous assessment work for IASME Cyber Assurance too?

Yes. Our Vulnerability Assessments support both Cyber Essentials Plus and IASME Cyber Assurance, helping you stay aligned to either standard all year.

We're a small business. Is this really for us?

Yes. The UK government's Cyber Security Breaches Survey 2025/26 found that 42% of micro businesses and 46% of small businesses identified a breach or attack in the last year. Attackers don't only go after big names.
