When you're considering an IT supplier or managed service provider, checking their Cyber Essentials certificate is a practical way to gauge their basic cybersecurity standards. Cyber Essentials is a UK government-backed scheme that sets out fundamental controls to protect organisations from common cyber threats. However, not all certificates are equal, and understanding what to look for helps you assess whether the supplier's security posture aligns with your business needs.
Why Cyber Essentials Matters for Your Business
Cybersecurity isn't just a technical issue—it directly affects your business continuity, customer trust, and legal compliance. If your IT provider lacks proper safeguards, your organisation could face downtime, data breaches, or ransomware attacks, which disrupt operations and damage your reputation. For UK SMEs, Cyber Essentials certification demonstrates that a supplier has implemented key controls like firewalls, secure configuration, access controls, malware protection, and patch management. This reduces risk and helps meet obligations under UK GDPR and the Data Protection Act 2018.
A Typical Scenario
Imagine a mid-sized UK business with around 100 staff outsourcing IT support. They engage a provider claiming Cyber Essentials certification. Later, a ransomware attack spreads through the provider's network, affecting multiple clients. On review, the provider's certificate was out of date, and their security controls hadn't been independently verified recently. A better IT partner would have kept their certification current and provided evidence of ongoing compliance, helping prevent or limit the attack's impact.
What to Check in a Supplier's Cyber Essentials Certificate
- Validity dates: Confirm the certificate is current and not expired. Cyber Essentials certificates are valid for 12 months, so an expired certificate offers no assurance.
- Certification level: Check if it's Cyber Essentials or Cyber Essentials Plus. The Plus version includes independent verification of controls and is more rigorous.
- Scope of certification: Ensure the certificate covers the relevant services or locations your business will use. Some providers certify only part of their operations.
- Certification body: Verify the certificate is issued by an accredited certification body recognised by the UK government.
- Proof of ongoing compliance: Ask how the provider maintains security between audits, including patching, access control, and incident response.
- Integration with other standards: If your business requires ISO 27001 or PCI DSS compliance, check how Cyber Essentials fits into the provider's broader security framework.
Questions to Ask Your IT Provider
- Can you provide a current Cyber Essentials or Cyber Essentials Plus certificate?
- Which parts of your service and infrastructure does the certification cover?
- How do you maintain security controls between certification audits?
- What processes do you have for patch management, multi-factor authentication, and access control?
- How do you support your clients' compliance with UK GDPR and data protection requirements?
Simple Internal Checks to Support Your Supplier Assessment
- Review your supplier contracts and ensure Cyber Essentials certification is a requirement or at least strongly encouraged.
- Request evidence of your provider's security policies and incident response plans.
- Check your own network access lists and ensure only authorised supplier personnel can connect.
- Confirm that backups of critical data are performed regularly and stored securely, ideally offsite or in the cloud.
In summary, a valid and appropriate Cyber Essentials certificate is a useful indicator of a supplier's commitment to cybersecurity, but it's not the whole story. Combining certificate checks with practical questions about ongoing security practices and clear contractual requirements will help you manage cyber risk effectively. Discuss your specific needs with a trusted managed IT provider or IT advisor who understands UK SME challenges and compliance expectations to ensure you choose a partner that supports your business securely and reliably.
