What are the key things for getting Cyber Essentials Certified?
You have probably heard of Cyber Essentials. It is often seen as a basic but important step towards improving your security posture, and in many cases, it is required when working with government contracts or larger organisations. What is sometimes less clear is what you actually need to have in place to achieve the certification.
At its core, Cyber Essentials is about demonstrating that you have covered the fundamentals. It is not about having the most advanced tools on the market. It is about showing that the most common attack paths have been addressed properly.
Firewalls
One of the first areas assessed is your boundary firewalls (including Windows Firewalls) and internet gateways. This means you need to have a properly configured firewall in place that controls incoming and outgoing traffic. For many small businesses, this will be your router or a dedicated firewall appliance. The key is that default passwords are changed, unnecessary ports are closed, and only required services are exposed to the internet. A surprising number of breaches still happen because of something as simple as an open port or a default credential being left in place.
Secure Configuration
Secure configuration is another major requirement. This focuses on how your devices are set up, whether that is laptops, desktops, servers, or mobile devices. Systems should not be running unnecessary software, and features that are not needed should be disabled. For example, if remote desktop access is not required, it should be turned off. Default settings are often designed for ease of use rather than security, so part of achieving Cyber Essentials is tightening those configurations to reduce risk.
Access Control
Access control is where many businesses need to pay closer attention. The principle here is simple. Users should only have access to the data and systems they actually need to do their job. Administrator privileges should be tightly controlled and only used when necessary. Shared accounts should be avoided where possible, and each user should have their own login. Multi factor authentication is not strictly mandatory for the basic certification in all cases, but it is strongly encouraged and increasingly expected as standard practice.
Patch Management
Keeping systems up to date is another key pillar. Patch management is one of the easiest ways to protect against known vulnerabilities, yet it is often overlooked. To meet the requirements, you need to ensure that operating systems, applications, and firmware are regularly updated. Critical security updates should be applied within a defined timeframe. This applies across the board, including firewalls, switches and any cloud-based services you rely on.
Malware Protection
Malware protection is also assessed as part of the certification. This means having appropriate anti-virus or endpoint protection in place, along with measures to prevent malicious software from running. Modern solutions often go beyond traditional antivirus and include behavioural analysis and threat detection. What matters for Cyber Essentials is that you have effective protection in place and that it is kept up to date and actively managed.
Staff Training
There is also an important human element to consider. While Cyber Essentials is a technical certification, the way your staff use systems plays a huge role in your overall security. Simple practices such as recognising phishing emails, using strong passwords and avoiding unknown downloads can make a significant difference. Many businesses support this with basic security awareness training alongside their technical controls.
Documentation
Lastly documentation of all these elements is a key requirement. Tracking changes and requests means you know why a setting is the way it is.
Achieving Cyber Essentials is ultimately about consistency. It is not enough to set things up once and forget about them. You need to be able to demonstrate that these controls are in place and maintained over time. For many organisations, working with an IT partner can help ensure everything is configured correctly and stays aligned with the requirements as systems change and grow.
For UK businesses looking to improve their security baseline, Cyber Essentials provides a clear and practical framework. It sets out what good looks like at a foundational level and helps reduce exposure to the most common cyber threats businesses face every day.
