Manufacturing Sector

Protecting your production line from cyber disruption.

Modern manufacturing relies on converged IT and OT systems, from ERP platforms to industrial control systems. This connectivity creates significant cyber risk. A single breach can halt production, compromise safety systems, and expose valuable intellectual property.

The threat landscape

Why manufacturers are increasingly in the crosshairs.

Manufacturing has become one of the most targeted sectors for ransomware. The combination of high operational pressure, where every hour of downtime costs thousands of pounds, and historically poor cyber security investment makes manufacturers an ideal target. Attackers know that a factory floor that cannot operate creates irresistible pressure to pay a ransom.

The convergence of IT and operational technology (OT) has dramatically expanded the attack surface. Legacy industrial control systems (ICS), SCADA platforms, and PLCs were never designed with cyber security in mind. When these systems are connected to corporate networks, or directly to the internet via remote access tools, they become accessible to attackers who can cause not just data loss, but physical damage to equipment and danger to personnel. Nation-state actors and criminal groups alike have demonstrated the capability and willingness to target industrial environments.

Key threat areas

The risks facing your operation.

OT & ICS Vulnerabilities

Legacy industrial control systems were designed for reliability, not security. When connected to modern networks, unpatched PLCs, SCADA systems, and HMIs create significant attack opportunities.

Supply Chain Attacks

Manufacturers rely on complex supplier networks. A compromised supplier with privileged access to your systems or a malicious component in your supply chain can introduce threats that bypass perimeter defences.

Intellectual Property Theft

Product designs, manufacturing processes, and R&D data represent your competitive advantage. Nation-state actors and industrial espionage campaigns specifically target this information.

Cyber risks

Threats specific to the manufacturing sector.

Poor IT/OT Network Segmentation

Corporate IT and operational technology networks are frequently connected without adequate controls, meaning a compromise in the office network can propagate directly to production floor systems.

Unpatched Legacy ICS and SCADA Systems

Industrial control systems often run operating systems that are years out of patch support. Vendors may not release patches quickly, leaving known vulnerabilities exposed for extended periods.

Ransomware Targeting ERP Systems

Enterprise resource planning systems hold production schedules, supplier data, and financial records. Ransomware encrypting these systems can halt procurement, planning, and invoicing simultaneously.

Insecure Remote Access to OT

Remote monitoring and maintenance access to industrial systems, often established during the pandemic, frequently lacks multi-factor authentication and strong access controls.

Supplier Portal and Third-Party Access

Suppliers and maintenance contractors often have privileged remote access to OT systems. If their credentials are compromised, attackers can enter your environment through trusted channels.

Phishing Targeting Engineering and Procurement Staff

Targeted phishing emails impersonating suppliers, logistics partners, or regulatory bodies are used to steal credentials or install malware on engineering workstations.

Weak Monitoring and Incident Detection

Most manufacturers lack the security monitoring to detect an attacker moving laterally through their environment. Attackers often dwell for weeks before deploying ransomware.

Physical Security Gaps Enabling Cyber Attacks

Unsecured USB ports on HMIs, lack of access controls to server rooms, and publicly visible network infrastructure can all be exploited by insiders or visitors.

FAQ

Frequently asked questions.

Why is manufacturing one of the most targeted sectors for ransomware?

Manufacturers face a combination of factors that make them attractive to ransomware operators: high operational pressure where every hour of downtime costs thousands of pounds, legacy OT systems that are difficult to patch, and historically lower investment in cyber security than other sectors. Attackers know that a factory that cannot produce creates intense pressure to pay quickly.

Can penetration testing be performed safely on operational technology environments?

Yes, but it requires specialist expertise. We assess OT environments using methodologies designed to avoid disruption to production systems. This includes passive network analysis, controlled testing of IT/OT boundary controls, and assessment of remote access mechanisms. We never perform active exploitation against live production control systems without explicit agreement and appropriate safety controls in place.

What is IT/OT segmentation and why does it matter?

IT/OT segmentation is the practice of separating your corporate IT network from your operational technology network so that a compromise in one cannot easily spread to the other. Without proper segmentation, an attacker who compromises a single office workstation through phishing can potentially reach SCADA systems, PLCs, and production line controls. Penetration testing identifies where these boundaries are weak or missing.

How do we protect intellectual property from cyber theft?

Product designs, manufacturing processes, and R&D data are frequently targeted by both criminal groups and nation-state actors. Protection starts with understanding where this data is stored and who has access to it. Penetration testing identifies weaknesses in network access controls, file server permissions, and endpoint security that could allow an attacker to locate and exfiltrate sensitive intellectual property.
