Many UK small businesses and SMEs find that demonstrating strong cybersecurity controls is becoming a standard part of working with larger clients or public sector organisations. Cyber Essentials Plus is a government-backed certification that shows your business has met specific technical requirements to protect against common cyber threats. Holding this certification can significantly ease the process of passing supplier security checks, which are often part of contract negotiations or ongoing vendor assessments.
Supplier security checks typically assess whether your business has adequate measures to prevent data breaches or service interruptions. If your systems are vulnerable, it can lead to downtime, loss of sensitive data, or damage to your reputation. For example, a retailer handling customer payment data must ensure compliance with PCI DSS and Cyber Essentials Plus to reduce the risk of fraud and maintain customer trust. Without these assurances, clients may hesitate to engage or renew contracts.
How Cyber Essentials Plus supports supplier security checks
Cyber Essentials Plus involves an independent technical audit that verifies your business's cybersecurity controls are working effectively. This includes testing your firewalls, secure configuration of devices, user access controls, malware protection, and patch management. Because the assessment is rigorous and externally validated, it provides credible evidence to your clients or partners that you take cybersecurity seriously.
Consider a typical UK SME with around 50 employees supplying IT services to a local council. The council requires all suppliers to demonstrate Cyber Essentials Plus certification as part of their security policy. The SME's IT provider helps them prepare by implementing multi-factor authentication (MFA), ensuring all devices are up to date with security patches, and configuring endpoint protection software. When the audit passes, the SME can confidently submit their certification with the tender. This reduces back-and-forth questions and speeds up contract approval.
Practical checklist to prepare for supplier security checks
- Ask your IT provider: Do they support Cyber Essentials Plus certification? Can they help with technical controls like patching, access management, and malware defences?
- Review your current security measures: Check if MFA is enabled for all critical systems and remote access. Verify that backups are performed regularly and stored securely offsite.
- Maintain an up-to-date inventory: Know what devices and software are in use, and ensure they are securely configured and patched.
- Document policies and procedures: Have clear records of your cybersecurity practices, including incident response plans and user training.
- Request supplier questionnaires early: When bidding for contracts, ask for security requirements upfront to identify if Cyber Essentials Plus or other certifications are needed.
While Cyber Essentials Plus does not guarantee passing every supplier security check, it provides a strong foundation and widely recognised assurance of your cybersecurity posture. Engaging a trusted managed IT provider or IT advisor can help you understand the specific requirements of your clients and prepare your business accordingly. This proactive approach reduces risks and supports smoother supplier relationships.
