Cybersecurity has become a critical concern for the UK’s industrial sector. This year, Marks & Spencer suffered a significant cyberattack that disrupted online operations for over a month, leading to an estimated £300 million loss in operating profit. This incident underscores the vulnerabilities in industrial systems. According to the UK Government’s Cyber Security Breaches Survey 2024, 74% of large businesses and 70% of medium-sized businesses reported experiencing a cybersecurity breach or attack in the past 12 months. These figures highlight the pressing need for robust cybersecurity measures to protect industrial digital infrastructure as organisations face increasingly complex and connected risks.

Cyber Attack Because of Poor Industrial Cyber Security

Cybersecurity in Industry: What Are the Challenges?

The digital transformation of UK industry has delivered major benefits, from process automation to real-time data insights and performance gains. But it has also expanded the attack surface for cybercriminals. Industrial systems connected to external networks are increasingly being targeted, often through overlooked or poorly secured entry points.

A single cyber attack can disrupt production, expose sensitive data, or even pose risks to staff safety. Systems such as industrial control systems (ICS), SCADA networks and connected devices used in factories tend to be more vulnerable than traditional IT infrastructure. These environments often lack the same level of security oversight, leaving critical operations exposed. The result can be significant financial losses and reputational damage.

Recent incidents have shown how severe the impact can be and why industrial cybersecurity needs to be taken seriously.

In one recent example, Smiths Group, a major UK engineering firm, confirmed unauthorised access to its IT systems in 2025. While the full extent of the breach was not disclosed, the Smiths Group Cyber attack triggered a comprehensive review of their cybersecurity protocols and highlighted how vulnerable manufacturing networks can be to disruption.

Likewise, chilled food logistics company Peter Green Chilled was hit by a cyberattack in May 2025, affecting their operations and delaying deliveries to UK supermarket chains. The cyber attack on Peter Green Chilled was reportedly ransomware-based, demonstrating the wider supply chain risks when key industrial players are compromised.

How to Strengthen Industrial Cyber Security

To protect critical systems from cyber attacks, industrial businesses need tailored security measures designed for operational environments.

Use USB Decontamination Stations

USB drives are still widely used in industrial settings to transfer data, but they are also a common source of malware. If a contaminated device is plugged into critical machinery, it can compromise the entire network.

Installing USB decontamination stations allows businesses to scan and clean removable media before use. These units, such as those offered by Tyrex, detect and remove malicious files before they reach sensitive systems. By placing them at key entry points, companies can prevent infected devices from disrupting operations.

Install Industrial-Grade Antivirus Software

Antivirus protection is often overlooked in OT environments, but it plays a vital role. Industrial antivirus software must be able to detect threats specific to control systems and connected machinery.

Regular updates are essential to maintain security. Modern antivirus tools can also detect unusual behaviour, making it easier to identify unknown malware and respond to zero-day threats before damage is done.

Choose Secure Server Architecture

Industrial companies should use secure servers designed to resist intrusion attempts and protect critical operational data. Servers must be configured to restrict access to authorised users only and preserve data integrity.

Segmentation is equally important. By dividing systems into separate zones, businesses can limit the spread of attacks and isolate any compromised area before it affects the whole operation.

Train Staff on Cyber Hygiene

Human error is a leading cause of cyber incidents. Training is essential to help staff spot risks early and respond appropriately. Regular awareness programmes should teach employees to:

  • understand cyber threats 
  • recognise phishing attempts 
  • handle tools and devices securely 

A strong culture of security is one of the most effective ways to protect against cyber attacks in any industrial setting.
