Cybersecurity in the glazing industry

In his latest column, Greg Du-feu, Managing Director of Dufeu IT, explains why Cybersecurity matters more than ever when it comes to trust between supplier and customer.

In the glazing industry, reputation and reliability are everything. Fabricators build long-term relationships with installers, merchants, and contractors based on trust — trust that deliveries will arrive on time, quotes will be honoured, and data will be handled securely.

But cybersecurity incidents are now one of the biggest threats to that trust. A single breach can shake confidence across your entire supply chain, leaving customers questioning whether they can rely on you again.

Here’s why cybersecurity is now as critical to customer relationships as product quality and delivery times.

The Supply Chain Reality

The glazing industry is more digitally connected than ever. ERP systems link suppliers and fabricators. Quotes and invoices are exchanged via email or online portals. Customer records, job details, and payment data are stored electronically.

Each one of these touchpoints creates opportunity — for you and for attackers.

When one business in the chain is compromised, it doesn’t just affect them — it can expose everyone connected.

How a Cyber Breach Damages Trust

1. Missed Deadlines & Downtime
   A ransomware attack on your ERP system halts production. Installers can’t get product. Contractors miss deadlines. Even if it’s not your fault, you’re the weak link.
2. Invoice Fraud
   Attackers who gain access to your email can impersonate you, sending fake bank details to your customers. Once a customer loses money this way, trust evaporates overnight.
3. Data Leaks
   If customer or supplier details are exposed, you may have to report the breach under GDPR. Clients rarely forget being part of a data incident.

The Ripple Effect

It’s not just about one missed job or one lost customer — it’s about perception.

• “Can they really keep our data safe?”
• “Will they be reliable next time?”

The damage from one breach can take years to undo, even if your systems are secure afterwards.

Rebuilding and Reinforcing Trust

Be Transparent:
If you suffer an incident, communicate quickly and clearly. Customers value honesty more than silence.

Show Your Credentials:
Certifications like Cyber Essentials Plus or ISO 27001 demonstrate that you’ve taken proactive steps to secure your business.

Document Your Controls:
Publish short cybersecurity statements on your website or in supplier onboarding packs. This reassures clients and meets growing compliance demands.

Review Third-Party Risks:
Assess your own suppliers. A secure partner network protects everyone.

The New Expectation

We’re already seeing large construction firms and councils demanding evidence of supplier cybersecurity before awarding contracts. Within the next few years, this will be standard practice across the entire industry.

By investing early, you’re not just protecting data — you’re future-proofing your credibility.

Real-World Example

A regional fabricator recently faced a phishing attack that led to fake invoices being sent to several of their installer customers. Even though the business quickly resolved it, three long-term partners paused new orders until proof of improved controls was provided.

That’s the real cost of losing trust.

Final Word

Your reputation isn’t built in a day — but it can be damaged in one click.

Cybersecurity isn’t an IT project; it’s a customer relationship investment.
