• The Hidden Cyber Risks In Your Supply Chain

Facilities Management businesses invest heavily in keeping buildings running smoothly, yet one of the biggest cyber risks often sits outside their control, their suppliers.

Most organisations focus their cyber security efforts internally. Systems are protected, software is updated, and staff have some awareness. It feels like a solid approach. But one of the most significant risks often sits within the supply chain

Why Supply Chain Risks are Increasing in Facilities Management

From maintenance contractors and HVAC engineers to cleaning providers and building system specialists, suppliers are essential to day-to-day operations.

Many require access to systems, data, or on-site infrastructure to do their job effectively. That access, if not properly controlled, can introduce serious vulnerabilities.

Cybercriminals are increasingly targeting these relationships. Rather than attacking well-protected organisations directly, they look for weaker entry points through smaller suppliers. Once compromised, a trusted supplier can unintentionally provide a route into multiple sites and systems.

How These Attacks Actually Happen

What makes this risk more concerning is how simple it can be to exploit. In many cases, it comes down to basic gaps such as:

• Shared or weak passwords
• Access that is never reviewed or removed
• Unsecured remote connections into building systems

A compromised supplier email account can also be used to send convincing invoices or requests, leading to fraud or further system access.

The Real Impact on Your Operations

For Facilities Management businesses, the consequences are not limited to data. A cyber incident involving a supplier can:

• Disrupt access control systems
• Impact HVAC and building management systems
• Affect CCTV or on-site security infrastructure
• Interrupt service delivery across multiple sites

In an industry where uptime, safety, and service continuity are critical, even a short disruption can have serious operational and reputational consequences.

How to Reduce the Risk

Reducing this risk does not require complex solutions. Start by:

• Understanding exactly who has access to your systems and sites
• Limiting access to what is necessary
• Removing access when it is no longer needed
• Reviewing supplier access regularly

It is also important to set clear expectations. Asking suppliers to meet recognised standards such as Cyber Essentials helps ensure a consistent level of security. Securing remote access with measures like multi-factor authentication adds another strong layer of protection.

Supply chains are built on trust, but trust needs to be supported by good security practices.

Many Facilities Management businesses don’t realise how much access their suppliers have until something goes wrong. Taking the time to review this now can prevent serious issues later.
