As businesses become increasingly dependent on connected machinery, industrial equipment and remotely managed systems, cybersecurity is no longer just an IT concern. It is a fundamental part of protecting business operations, ensuring equipment availability and maintaining business continuity.

The growing cybersecurity risk beyond traditional IT

Recent cyberattacks targeting supermarket refrigeration systems across Europe have highlighted a growing concern for businesses operating connected infrastructure.
In November 2026, cyber incidents affected supermarket refrigeration systems in several European countries, with attackers reportedly manipulating cooling controls and causing temperatures to rise significantly. The incidents resulted in product losses and operational disruptions, demonstrating how a cyberattack can have consequences that extend well beyond computer systems and corporate networks.
What makes these incidents particularly important is that the targeted systems were not traditional IT infrastructure. They were operational technology (OT) systems responsible for controlling physical equipment and maintaining essential operating conditions.
Today, industrial machinery, production lines, HVAC systems, refrigeration installations, pumps, generators, building management systems and other specialised equipment increasingly rely on connected technologies, sensors, remote access and centralised control platforms.
While connectivity offers significant operational benefits, it also introduces new potential vulnerabilities.

A compromised system, unauthorised access or undetected equipment anomaly can result in production interruptions, equipment damage, financial losses and disruption to essential business operations.

The question businesses need to ask is no longer simply whether their IT infrastructure is protected.

It is whether their entire operational environment is being monitored and secured.

Why connected machinery needs greater protection

The convergence of Information Technology (IT), Operational Technology (OT) and the Internet of Things (IoT) is transforming how businesses manage their facilities and operations.
Equipment that was traditionally operated and maintained locally can now be monitored, controlled and managed remotely. Sensors collect operational data, connected devices communicate with central platforms, and maintenance teams can access equipment information from different locations.
However, this increased connectivity also expands the potential attack surface.
Some of the most common risks include:

1. Unauthorised remote access

Remote connectivity enables businesses to manage equipment more efficiently, but poorly secured remote access can expose critical systems to external threats.

Weak authentication, excessive user permissions, unsecured connections or exposed management interfaces may allow unauthorised individuals to access operational equipment and potentially modify system configurations.

2. Outdated equipment and software vulnerabilities

Many industrial and commercial environments rely on machinery that operates for years or even decades.

Legacy controllers, outdated firmware, unsupported software and unpatched vulnerabilities can create security gaps that attackers may exploit.

In some cases, updating operational equipment is not straightforward, as changes must be carefully planned to avoid affecting production, safety or equipment availability.

3. Insufficient network segmentation

When operational systems share network infrastructure with corporate IT environments, a security incident affecting one part of the organisation may create opportunities to access other systems.

Without appropriate network segmentation and access controls, critical machinery and industrial control systems may be exposed to threats originating elsewhere in the network.

4. Limited visibility into operational environments

Businesses may have monitoring systems for individual machines or facilities, but lack a centralised view of their overall operational infrastructure.

Without continuous monitoring, abnormal operating conditions, unexpected configuration changes or suspicious system activity may remain undetected.

5. Delayed detection and response

Even when security solutions are in place, organisations need the ability to identify, investigate and respond to potential incidents.

Without appropriate alert management, event correlation and incident response procedures, suspicious activity may go unnoticed until it affects equipment availability or business operations.

From equipment monitoring to operational visibility

Protecting critical infrastructure starts with understanding what is happening across the operational environment.

Continuous monitoring provides businesses with greater visibility into equipment performance, operating conditions and potential anomalies.

Through IoT-enabled monitoring solutions, organisations can collect operational data from connected equipment and monitor critical parameters remotely.

Depending on the equipment and available integrations, these parameters may include:

• Temperature and humidity levels.
• Pressure and flow rates.
• Equipment operating status.
• Energy consumption and power conditions.
• Operating hours and performance indicators.
• Other predefined operational measurements.

By establishing acceptable operating thresholds, businesses can receive notifications when measurements fall outside expected ranges.

This allows maintenance and operations teams to identify potential problems earlier, investigate abnormal conditions and take corrective action before they escalate.

For example, an unexpected temperature increase in a refrigeration installation, an abnormal pressure reading in an industrial system or a change in the operating status of critical machinery could indicate a technical issue requiring attention.

Remote monitoring helps organisations move away from relying exclusively on manual inspections or reacting after a failure has occurred.

It provides an additional layer of operational awareness and supports more proactive equipment management.

However, monitoring equipment performance is only one part of the picture. The systems collecting and transmitting this information must also be protected.

Why cybersecurity must extend to OT and IoT environments

Traditional cybersecurity strategies have primarily focused on protecting corporate networks, servers, endpoints and business applications.

Today, organisations also need to consider the security of the systems that directly interact with their physical operations.

OT and IoT environments require security measures that take into account their specific operational requirements.

Unlike conventional IT systems, industrial equipment may have strict availability, reliability and safety requirements. Security measures therefore need to be implemented carefully, without compromising essential processes.

A comprehensive approach should include several complementary security capabilities.

Network Security: Protecting the infrastructure behind critical operations

Network Security solutions help organisations protect the communication infrastructure connecting their IT, OT and IoT environments.

Appropriate network protection can help businesses:

• Control access to critical systems and network resources.
• Implement network segmentation between corporate and operational environments.
• Secure remote connectivity.
• Monitor network traffic for suspicious activity.
• Reduce the exposure of critical equipment to external threats.

The objective is to ensure that connected machinery and operational systems communicate securely and remain accessible only to authorised users and services.

Endpoint Security: Protecting connected systems and devices

Endpoints and supporting systems can provide entry points for cyber threats.

Endpoint Security solutions help protect compatible devices and systems against malware, malicious activity and other security threats.

By improving endpoint visibility and protection, organisations can reduce the risk of compromised devices affecting their wider infrastructure.

In OT environments, endpoint protection must be selected and deployed with consideration for equipment compatibility, performance and operational availability.

OT/IoT Security: Securing connected operational environments

As businesses increasingly depend on connected machinery, securing operational technology and IoT devices becomes essential.

OT/IoT Security focuses on identifying connected assets, improving visibility into operational environments and reducing vulnerabilities associated with industrial devices and control systems.

This includes:

• Improving visibility into connected devices and operational assets.
• Identifying potential security weaknesses.
• Monitoring communication between systems.
• Detecting suspicious activity and unauthorised access.
• Strengthening the protection of industrial control environments.

By extending cybersecurity beyond traditional IT infrastructure, organisations can develop a more comprehensive understanding of their security exposure.

Vulnerability Management: Identifying weaknesses before they are exploited

Unpatched systems, outdated firmware and insecure configurations can expose critical infrastructure to cyber threats.

Vulnerability Management helps organisations identify, assess and prioritise security weaknesses across their infrastructure.

A structured approach enables businesses to understand which vulnerabilities represent the greatest risk and plan appropriate remediation activities.

For operational environments, remediation must also consider equipment compatibility, manufacturer recommendations and the potential impact of changes on production and system availability.

The importance of continuous monitoring and SOC services

Implementing security technologies is an important step, but protecting critical infrastructure requires ongoing visibility and supervision.

Cyber threats evolve continuously, and suspicious activities may not always be identified by individual security tools operating independently.

This is where Managed Monitoring and Security Operations Centre (SOC) services become particularly valuable.

Through continuous monitoring and security event correlation, organisations can improve their ability to identify potential threats across their IT, OT and IoT environments.

SOC services can support businesses through:

• Continuous monitoring of infrastructure and security events.
• Identification of suspicious activities and potential threats.
• Correlation of security events from different systems.
• Investigation and prioritisation of security alerts.
• Early identification of incidents that could affect business operations.
• Incident response coordination and support.

Consider a scenario in which a critical industrial machine experiences an unexpected configuration change while suspicious remote access activity is detected within the same operational environment.

Looking at these events independently may not provide sufficient context. However, correlating relevant security events can help identify a potentially serious incident and support a more informed investigation.

This combination of monitoring, detection and response helps organisations move towards a proactive security approach rather than relying exclusively on reactive incident management.

Bringing everything together: A more resilient operational environment

Monitoring, cybersecurity and managed security services should not operate as isolated capabilities.

They address different aspects of the same business challenge: maintaining control, visibility and protection across critical infrastructure.

An integrated approach combines three essential capabilities.

1. Monitor – Gain visibility into critical equipment

IoT & Remote Monitoring solutions provide continuous visibility into equipment performance and operating conditions.

Organisations can monitor predefined parameters, record measurements and receive alerts when abnormal conditions are detected.

2. Protect – Secure connected infrastructure

Cybersecurity solutions help protect the networks, endpoints, operational systems and connected devices that support business operations.

Network Security, Endpoint Security, OT/IoT Security and Vulnerability Management help reduce exposure to cyber threats and unauthorised access.

3. Detect – Identify and respond to potential threats

Managed Monitoring & SOC Services provide continuous security oversight, event correlation and threat detection to help organisations identify suspicious activity and respond to potential incidents.

Together, these capabilities provide a more comprehensive approach to operational visibility, infrastructure protection and business resilience.
