Cyber Essentials vs Cyber Essentials Plus

Whilst Cyber Essentials provides foundational security measures, Cyber Essentials Plus takes it a step further with additional layers of verification. Cyber Essentials focuses on self-assessment and provides a basic level of security, whereas Cyber Essentials Plus requires an external assessment, offering a more robust certification.

Why Is Cyber Essentials Important?

In the current climate, where cyber security cannot be overlooked, Cyber Essentials is the fundamental baseline for protecting your organisation’s digital assets. The significance of this becomes even more pronounced in today’s digital environment, where cyber threats are a constant and looming presence. This expanded section will explore the various facets that render Cyber Essentials an indispensable tool for any organisation.

  • Beyond the risk of data loss or theft, businesses face legal outcomes if they fail to meet cyber security standards.
  • Data protection laws, such as the General Data Protection Regulation (GDPR), have stringent requirements for data protection.
  • Organisations can face substantial fines for non-compliance.

Competitive Advantage

  • Customers are more likely to trust a certified organisation, knowing their data is secure and can be easily searched for on the Cyber Essentials Certificate Search Site.
  • A Cyber Essentials certification can also be a prerequisite for participating in government tenders or landing larger corporate clients.

Reducing Vulnerability

  • The Cyber Essentials scheme aims to mitigate risks from various cyber threats.
  • It protects against malware infections, social engineering attacks, and advanced persistent threats (APTs).

Reputational Benefits

  • A data breach can be devastating for a company’s reputation.
  • Certification is a publicly verifiable way to show commitment to cyber security.

Financial Incentives

  • Beyond avoiding fines, implementing Cyber Essentials can result in overall cost savings.
  • Identifies and fixes security vulnerabilities before they can be exploited.

Future-proofing the Business

  • As cyber threats evolve, so too must your cyber security measures.
  • The framework is designed to be adaptive, allowing businesses to avoid emerging threats.

By examining these various facets, it becomes evident that Cyber Essentials is more than just a certification. It’s a comprehensive approach to cyber security that confers multiple benefits, including legal protection, competitive advantage, and reputational enhancement, among others.

Core Requirements of Cyber Essentials

The cornerstone of certification is the adherence to five core technical controls. These controls form the basis of a robust cyber defence strategy. Each rule addresses a different facet of cyber security, aiming to create a holistic protective framework for organisations of all sizes.

Firewalls act as the first defence against unauthorised access to your network. They serve as a barrier between your internal systems and the outside world.

Key Considerations:

  • Ensure firewalls are correctly configured to block all unauthorised incoming and outgoing traffic.
  • Regularly update firewall rules to adapt to emerging threats.
  • Verify the firewall configurations on all devices, not just servers and desktops but also mobile devices.

Secure Configuration

Securing system configurations is essential for reducing the potential attack surface.


  • Conduct an audit to identify systems that are unnecessarily exposed to the internet.
  • Remove or turn off unnecessary software or services.
  • Limit user and administrative permissions to only what is necessary for each role.

User Access Control

Restricting who has access to your systems and data minimises the risk of data breaches and unauthorised access.

Important Measures:

  • Implement robust password policies.
  • Use multi-factor authentication wherever possible.
  • Maintain an updated list of personnel with access permissions, revising it as employees join or leave the organisation.

Malware Protection

Robust malware protection is essential for defending against various forms of malicious software, including viruses, ransomware, and spyware.

Best Practices:

  • Employ a reliable antivirus and anti-malware solution.
  • Keep all malware definitions up to date.
  • Regularly scan systems for signs of malware and review the reports for anomalies.

Patch Management

Keeping your software and systems up-to-date ensures that you are protected against known vulnerabilities.

Essential Steps:

  • Develop a systematic approach for updating and patching software.
  • Prioritise patches based on the criticality of the software and the severity of the vulnerability.
  • Test updates in a controlled environment before rolling them out across the organisation.

By implementing these core requirements effectively, you lay a solid foundation for your organisation’s cyber security. Failing to do so not only increases your vulnerability but may also disqualify you from achieving certification. It is advisable to consult experts or external services if you need help to implement these controls effectively.
