A Cyber Essentials readiness example is most useful when it reflects the untidy reality of a working business: staff using Microsoft 365 from home, a mix of laptops, an ageing office PC and a few systems that only one person understands. The goal is not to produce paperwork that looks reassuring. It is to identify what could prevent a successful certification application, then fix it without disrupting the business.
For most SMEs, readiness comes down to having a clear view of devices, users, software and access. That sounds straightforward, but gaps often appear when a business has grown quickly, changed IT providers or adopted cloud tools one department at a time.
A Cyber Essentials readiness example in practice
Consider a 28-person accountancy practice with one Midlands office and several employees working remotely each week. The practice uses Microsoft 365, cloud accounting software, a shared document platform and two networked printers. Most staff have company-issued Windows laptops, while three directors use personal Macs to access email and files.
The practice wants Cyber Essentials certification because clients increasingly ask for evidence of cyber security controls before sharing financial information. It also wants a more confident answer when its staff ask whether a new app, laptop or supplier is safe to use.
A readiness review begins by agreeing the assessment scope. In this case, that includes office networking equipment, company laptops, directors’ Macs, mobile phones used for work email, Microsoft 365 accounts and the cloud services that process or store client data. Leaving personal devices out of scope might appear simpler, but it would not reflect how the business operates. If those devices access in-scope business information, they need to meet the required controls too.
What the initial review found
The first review showed that the practice was in a better position than it expected. Its office firewall was active, laptops had centrally managed antivirus protection and Microsoft 365 multi-factor authentication was enabled for most users. However, several issues needed attention.
Two former employees still had active Microsoft 365 accounts. One director’s Mac was running an operating system version that no longer received security updates. Four laptops had not restarted for several weeks, so their updates had not fully installed. Local administrator rights had also been granted to more users than necessary, largely to avoid delays when staff needed new software.
None of these findings meant the organisation had poor security. They did show how routine exceptions can become compliance and business risks when no one reviews them. Cyber Essentials is designed around practical controls, and the test is whether those controls are working consistently across the organisation.
Turning findings into a workable action plan
The priority is to resolve issues according to risk and practical impact. Active accounts for leavers are dealt with first, followed by unsupported operating systems and missing security updates. Those problems create obvious opportunities for unauthorised access or known vulnerabilities to be exploited.
For the accountancy practice, the plan was completed over two weeks. The former employee accounts were blocked and removed after mailbox and file ownership checks. The unsupported Mac was upgraded, while one old laptop that could not support the current Windows version was replaced. Staff were asked to restart their machines during a scheduled evening window, allowing outstanding updates to finish without interrupting client work.
Administrator access needed a more balanced solution. Removing it from everyone can frustrate staff and slow down work, particularly in a smaller business without an internal IT department. Instead, the practice moved to standard user accounts for day-to-day work and set up a controlled process for approved software installation. This reduced exposure without making people wait unnecessarily when they needed a legitimate tool.
The remaining checks covered five areas that commonly determine whether a business is ready:
- A firewall or equivalent boundary protection is correctly configured for the office and remote devices.
- Devices use supported operating systems and receive security updates within an appropriate timeframe.
- User accounts are individually assigned, protected with suitable authentication and removed promptly when people leave.
- Malware protection is active and centrally monitored, or an alternative managed approach provides equivalent protection.
- Only necessary software is installed, with a process to control applications and remove anything no longer needed.
The exact technical answer depends on the business. A cloud-first company with no on-premises server will look different from a manufacturer with specialist machinery or a practice running line-of-business software. The principle is the same: understand what connects to your data, who can access it and whether it is kept secure.
Evidence matters as much as the controls
A common mistake is to make improvements but be unable to show how they are managed. Readiness is easier when evidence is gathered as the work is completed rather than chased at the point of application.
For this example, the practice created a simple asset register showing each laptop, Mac, mobile device, operating system and assigned user. It documented its password and multi-factor authentication settings, retained screenshots of firewall and endpoint protection dashboards, and recorded the dates that unsupported equipment was upgraded or replaced.
The business also formalised its joiner and leaver process. New starters receive an individual account, the right level of access and multi-factor authentication before their first day. When someone leaves, their manager notifies the responsible person, access is disabled promptly and company equipment is returned or wiped. This is not glamorous administration, but it is one of the most effective ways to avoid preventable security incidents.
It helps to name an owner for each control. In a small organisation, that might be the operations manager supported by an outsourced IT partner. The owner does not need to solve every technical issue personally. They do need confidence that updates, access changes and security alerts have a clear route to action.
Readiness is not the same as passing once
Cyber Essentials certification is an important milestone, but it should not become a once-a-year exercise. New staff join, laptops are replaced, software subscriptions change and cyber threats evolve. A business can drift away from its intended controls surprisingly quickly.
The accountancy practice therefore set monthly checks for outstanding device updates and endpoint protection alerts, plus a quarterly review of users, administrator permissions and the asset register. It also added Cyber Essentials requirements to its technology purchasing process. Before a new application or device is approved, the business now checks who will use it, what data it will access and whether it can be managed securely.
This approach also makes renewal far less stressful. Rather than trying to reconstruct the past year from inboxes and invoices, the business has a current record of its environment and a regular rhythm for maintaining it.
When more work may be needed
Some organisations discover that Cyber Essentials readiness exposes wider IT issues. A company may have unsupported servers, unmanaged personal devices, shared accounts, weak Wi-Fi separation or no reliable record of its software licences. These are not reasons to postpone the process indefinitely. They are useful signals that the business needs a phased improvement plan.
There can be cost decisions involved. Replacing every older device immediately may not be commercially sensible, for example, but continuing to use an unsupported device that handles business data is rarely a viable long-term option. A practical IT partner can help assess the exposure, introduce interim safeguards where appropriate and plan replacement around budget and operational priorities.
For businesses considering Cyber Essentials Plus, the standard of day-to-day control matters even more because parts of the implementation are independently tested. Building good habits before applying is generally more valuable than rushing to complete a questionnaire.
Nubis 365 supports organisations that need both the technical checks and the practical guidance to get ready. The strongest outcome is not simply a certificate on the wall. It is a business where people can work confidently, systems are easier to manage and security decisions are no longer left until something goes wrong.
