Cyber Essentials is a government-backed cybersecurity certification scheme in the UK that helps organisations protect themselves against common cyber threats. The scheme is built around five key security controls, which form the core of the Cyber Essentials requirements. These controls are designed to address the most common vulnerabilities that could be exploited by cyber attackers.

In this article, we’re going to discuss the Cyber Essentials Requirements and provide a Cyber Essentials Plus checklist to help you be as prepared as you can. We’ll go through the objectives and requirements for each point, as well as how you can achieve them.
Here’s a detailed breakdown of the Cyber Essentials requirements:
1. Firewalls and Internet Gateways
Objective: To secure your internet connection by preventing unauthorised access to or from private networks.
Firewalls act as the first line of defence between your network and external networks, including the Internet. They filter incoming and outgoing traffic, allowing only authorised communications to pass through while blocking potentially harmful data.
Internet Gateways are devices that manage traffic between your internal network and external networks, adding an additional layer of protection.
Requirements
- Ensure that all devices connected to your network have a properly configured firewall.
- Change default passwords on the firewall to something unique and secure.
- Block all incoming traffic by default, unless it is explicitly needed for business operations.
- Configure outbound traffic rules to restrict access to only necessary services.
2. Secure Configuration
Objective: To ensure that systems are securely configured to reduce vulnerabilities.
When systems are deployed with default settings, they often include unnecessary services or open ports that can be exploited by attackers. Secure configuration is all about disabling these unnecessary features and making sure the system is set up in a way that minimises security risks.
Requirements
- Disable or remove any unnecessary accounts, including guest or administrator accounts.
- Ensure that all default passwords are changed to strong, unique passwords.
- Remove or disable any unnecessary software or services.
- Regularly review and update system configurations to maintain security.
3. User Access Control
Objective: To control who has access to your data and services.
Limiting access to sensitive information and critical systems is essential to prevent unauthorised actions, whether intentional or accidental. User access control ensures that only authorised personnel can access certain parts of the network or specific data.
Requirements:
- Implement the principle of least privilege, ensuring users only have access to the information and systems necessary for their role.
- Use multi-factor authentication (MFA) wherever possible to add an additional layer of security.
- Regularly review user accounts and permissions, especially when employees change roles or leave the organisation.
- Enforce strong password policies and require regular password updates.
4. Malware Protection
Objective: To protect against malicious software that could damage or compromise your systems.
Malware, such as viruses, ransomware, and spyware, pose a significant threat to organisations. Malware protection measures are critical to detecting and neutralising these threats before they can cause harm.
Requirements:
- Install anti-malware software on all devices and ensure it is kept up to date.
- Enable real-time scanning of files and emails to detect and block malicious software.
- Use application whitelisting to allow only trusted applications to run on your systems.
- Regularly update all software to patch any vulnerabilities that could be exploited by malware.
5. Patch Management
Objective: To keep software and devices up to date with the latest security patches.
Cyber attackers often exploit known vulnerabilities in software to gain access to systems. Patch management ensures that all software and devices are regularly updated to close these security gaps.
Requirements:
- Apply security patches within 14 days of their release to address critical vulnerabilities.
- Enable automatic updates wherever possible to ensure patches are applied promptly.
- Maintain an inventory of all software and devices to monitor their patch status.
- Test patches before deployment to ensure they do not disrupt business operations.
The importance of meeting cyber essentials requirements
Understanding and meeting Cyber Essentials requirements is crucial for several reasons; The Cyber Essentials framework is designed to defend against prevalent threats, offering a practical, step-by-step approach to mitigate risks.
In an increasingly regulated environment, where data protection laws and industry standards are stringent, adhering to Cyber Essentials can also help ensure compliance with legal and regulatory requirements, avoiding potential fines and legal issues. However, achieving Cyber Essentials certification is not just about compliance; it’s also about building a solid foundation for cybersecurity that helps protect sensitive data, maintain operational integrity, and foster trust with clients and stakeholders.
Cyber Essentials certifications can also offer a competitive edge. As businesses strive to differentiate themselves, demonstrating a commitment to cybersecurity through certification can enhance credibility, attract new clients, and reassure existing customers that their data is secure. Plus, with cyber insurance becoming a more integral part of business risk management, having Cyber Essentials certification can potentially reduce insurance premiums and ensure smoother claims processes.
Ultimately, meeting Cyber Essentials requirements is more than just ticking boxes; it’s about embedding cybersecurity best practices into your organisation’s culture and operations. By doing so, you can not only defend against common cyber threats but also position your organisation as a trusted, secure partner in the digital age.
The Cyber Essentials requirements form a robust foundation for any organisation’s cybersecurity strategy. By implementing these controls, businesses can significantly reduce their vulnerability to common cyber threats and protect their digital assets. Whether you’re a small business or a larger organisation, adhering to these requirements is a critical step in ensuring your cybersecurity resilience.
