For UK SMEs, cyber security is increasingly part of the buying conversation, not simply an IT conversation. 

October is often filled with advice about passwords, phishing and multi-factor authentication. Those controls matter, but for many UK businesses the more immediate commercial question is different: could your cyber security position affect whether a customer chooses you? 

That question is becoming more relevant as larger organisations, public-sector buyers and supply chains ask suppliers to demonstrate how they manage cyber risk. The National Cyber Security Centre notes that a growing number of organisations require suppliers to hold Cyber Essentials certification to bid for work. 

For a growing SME, cyber security can therefore influence revenue, procurement, renewal conversations and customer confidence. Here are five ways that happens. 

1. A customer asks for evidence before they will onboard you 

A sales conversation can move quickly until procurement sends a security questionnaire. Suddenly the business needs to explain how accounts are secured, how devices are managed, whether backups are tested, how incidents are handled and who can access customer information. 

The issue is not whether you can produce an impressive policy document. The issue is whether the answers reflect what actually happens in the business. Mature customers increasingly want evidence that controls exist and are maintained, not simply promises that security is taken seriously. 

Business question: If a key prospect sent you a 50-question security questionnaire this afternoon, who would own it and how many answers could you support with evidence? 

2. Cyber Essentials becomes part of the buying criteria 

Cyber Essentials is a UK Government-backed scheme built around five technical control areas. For some organisations it is a useful baseline. For others it may be a contractual, supply-chain or procurement requirement. 

That changes the value of certification. It is no longer only a badge for the website. It can become part of demonstrating that the organisation has put recognised technical controls in place and is prepared to maintain them. Cyber Essentials Plus takes this further by adding independent technical verification. 

Business question: Are you waiting for a customer to ask for Cyber Essentials before finding out whether you are ready? 

3. Your Microsoft 365 environment tells a story about how risk is managed 

Many SMEs now run a significant portion of the business through Microsoft 365. Email, files, identities, shared data and collaboration all depend on it. A customer may never see the configuration, but weak identity controls or unmanaged access can still become part of a security review, insurance conversation or incident. 

Consistent multi-factor authentication, sensible access controls, privileged-account management and regular review are not merely technical housekeeping. They help demonstrate that access to business and customer information is being managed deliberately. 

Business question: Could you explain who has privileged access to your Microsoft environment, why they have it and when that access was last reviewed? 

4. Your ability to recover may matter as much as your ability to prevent 

Customers depend on suppliers being available. If your systems are disrupted, the impact can travel downstream into their business. That is why security conversations increasingly include resilience, backup and incident response. 

Having backups is not the same as knowing the business can recover. Leadership should understand what needs to come back first, how long recovery could take, who communicates with customers and what happens if Microsoft 365, a line-of-business platform or key infrastructure is unavailable. 

Business question: Could you show a customer that your recovery plan reflects the services they depend on you to provide? 

5. Confidence during due diligence can become a competitive advantage 

No organisation can promise that a cyber incident will never happen. A mature buyer understands that. What they want to see is whether a supplier understands its risks, has appropriate controls, can explain ownership and has a plan for responding when something goes wrong. 

That creates an opportunity. A smaller business that can answer security questions clearly and provide credible evidence can appear easier to trust than a larger competitor that treats assurance as last-minute paperwork. 

Business question: Is your cyber security posture helping your sales team answer buyer concerns, or creating another hurdle late in the deal? 

Cyber Security Has Become Part of Commercial Readiness 

The most useful cyber security programme is not one designed to frighten the business into buying more tools. It is one that helps the organisation reduce unnecessary risk, maintain the controls customers expect and respond confidently when someone asks, “How do you know?” 

For CBH clients, that can mean bringing managed IT, Microsoft 365 security, Cyber Essentials readiness, business continuity and ongoing cyber management into one conversation rather than treating each as a separate project.

CBH takeaway: good cyber security should make the business easier to trust, easier to insure, easier to assess and better prepared to keep operating.

What Should You Do Next? 

Before the next tender, supplier review or customer questionnaire arrives, review the evidence behind your answers. Identify where controls exist, where they are inconsistent and where the business is relying on assumptions. If Cyber Essentials or broader assurance is likely to matter to your customers, prepare before it becomes a deadline.

Frequently Asked Questions 

Why do customers ask suppliers about cyber security? 

Customers may depend on suppliers to handle data, connect to systems or maintain business-critical services. Security questionnaires and certification requirements help them assess third-party risk before awarding or renewing work. 

Is Cyber Essentials required for every UK business? 

No. Requirements vary by customer, contract and sector. However, Cyber Essentials is increasingly used in supply chains and some procurement processes, so organisations should understand whether it matters to their current or target customers. 

What should an SME have ready for a security questionnaire? 

Useful evidence can include details of access controls, multi-factor authentication, device management, security updates, backups, incident response, policies, supplier management and recognised certifications where applicable. 

Can CBH help with Cyber Essentials preparation? 

Yes. CBH can help organisations understand the technical requirements, assess the current environment, identify remediation work and prepare for Cyber Essentials or Cyber Essentials Plus assessment.
