The Hidden IT Risks Threatening Your Manufacturing Operation (And How to Solve Them)

The manufacturing industry has become the most targeted sector for cyberattacks worldwide, accounting for 26% of all incidents according to the IBM X-Force Threat Intelligence Index, making it the most attacked industry for the fourth consecutive year. But the IT challenges facing today’s factory operations go far beyond cybersecurity.

Legacy systems that cannot talk to modern platforms, production floors running on unpatched software, supply chains with dozens of vendor connections, and a talent shortage that leaves the vast majority of manufacturers struggling to find qualified IT staff all create an environment where a single IT failure can shut down entire production lines, throw delivery schedules into chaos, and generate millions in lost revenue.

Every hour of downtime in manufacturing translates into significant financial losses. According to Comparitech research, the average cost of a ransomware attack in the manufacturing sector is approximately $1.9 million in daily downtime losses, contributing to roughly $17 billion in damages across the industry from 2018 to 2024. The financial pressure is so severe that some manufacturers pay ransoms simply to resume operations.

These are not cybersecurity problems in isolation. They are IT management problems where cybersecurity has to be built into every layer. This guide covers the IT challenges every manufacturer faces and why solving them requires a managed IT partner that puts cyber resilience at the center of everything.

Legacy Systems and the Integration Gap

Many manufacturers still rely on older legacy machines and systems that were not designed for modern data connectivity. These systems run critical production processes, but they create data silos that prevent a unified view of operations and block the adoption of newer Industry 4.0 technologies.

The challenge is real: legacy OT systems cannot easily integrate with cloud computing platforms, modern analytics tools, or centralized monitoring dashboards. The result is fragmented data that prevents real-time tracking of raw materials, production status, and finished goods. Manual data reporting replaces automated visibility, slowing decision-making at every level.

Manufacturers must modernize legacy infrastructure while simultaneously securing complex networks and maintaining production uptime. This is not a weekend project. It requires a strategic migration plan that prioritizes the most critical systems, maintains production continuity during transitions, and ensures that every new connection point is secured from day one.

Older systems that go unpatched are not just inefficient. They are vulnerable. When ERP systems, SCADA systems, programmable logic controllers, and distributed control systems run outdated software, they become easy targets for threat actors looking to disrupt industrial operations or steal valuable intellectual property.

The Converging IT and OT Attack Surface

The convergence of IT and OT systems in modern manufacturing has widened the attack surface dramatically, increasing the number of potential entry points for cybercriminals. Smart factories rely on industrial IoT devices, sensors, remote monitoring, cloud platforms, and mobile applications that offer real advantages in efficiency and visibility. But every connected device is a potential door into your environment.

Without proper network segmentation, a single compromised IoT device on the production floor can spread malware across both OT environments and corporate IT systems. The Cybersecurity and Infrastructure Security Agency (CISA) recommends segmenting networks and implementing zero trust strategies to reduce exposure in connected manufacturing environments.

Industrial control systems, including SCADA systems and programmable logic controllers, were originally designed for isolated networks. Connecting them to the internet or corporate networks without proper security controls creates vulnerabilities that threat groups actively exploit. A cyber attack on these systems does not just steal data. It can disrupt industrial processes, damage equipment, create faulty products, and put worker safety at risk through cyber-physical damage.

Network security in manufacturing requires treating both IT and OT as a unified environment with consistent security controls, monitoring, and incident response across both domains. A cybersecurity services partner with manufacturing experience can design and maintain this unified security architecture.

Ransomware and the Manufacturing Downtime Crisis

Ransomware attacks are one of the most disruptive cyber threats to manufacturing, with 65% of manufacturers reporting being hit by such attacks according to Sophos, leading to costly downtime and lost output. Manufacturing is now the top target for ransomware worldwide because attackers know that production downtime creates immediate financial pressure to pay.

A ransomware attack on a manufacturer does not just encrypt files. It halts production lines, delays shipments, disrupts customer orders, and can cascade across industries that depend on your output. The financial and operational impact extends far beyond the ransom demand itself: recovery costs, forensic investigation, legal exposure, customer notification, and the reputational damage of missed deliveries all compound the loss.

The defense against ransomware in manufacturing starts with the fundamentals: reliable tested backups stored on immutable and air-gapped storage, aggressive patch management for all systems (especially internet-facing ones), endpoint detection and response across all devices, and 24/7 real-time monitoring that catches anomalies before encryption begins.

Supply Chain Vulnerabilities

Manufacturers rely on complex, global supply chains that are highly susceptible to disruption from cyberattacks, geopolitical tensions, natural disasters, and logistics bottlenecks. Manufacturers often depend on a wide network of suppliers and vendors, and cybercriminals frequently exploit these connections by targeting smaller vendors with weaker defenses. A successful supply chain attack does not just compromise one company. It cascades: production delays, missed shipments, and service disruptions ripple across every business in the chain. Supply chain attacks in manufacturing increased by over 400% according to the European Union Cybersecurity Agency (ENISA), and the trend has only accelerated.

Securing the supply chain requires vendor risk assessments before onboarding new partners, strict access controls for vendor connections, continuous monitoring of third-party access, and contractual security requirements that hold vendors to the same standards you maintain internally. For a deeper look at managing vendor risk, see our guide to third-party security risk management.

Intellectual Property and Data Theft

Manufacturers hold trade secrets, proprietary processes, product designs, customer databases, and employee data that represent years of competitive advantage. Intellectual property theft is one of the most damaging cyber risks in manufacturing because the stolen data can be used by competitors, sold on the dark web, or leveraged for extortion.

Insider threats, where employees misuse their access to sensitive information, pose significant risks alongside external attacks. Both require strict access controls based on the principle of least privilege, multi-factor authentication on every system that touches sensitive data, activity logging on sensitive systems, and regular access reviews to ensure that only the people who need access have it.

Data theft in manufacturing is not always dramatic. It can be a departing employee copying files to a personal drive, a compromised vendor account exfiltrating production data, or ransomware operators stealing data before encrypting it for double extortion. The damage may not be visible for months or years, but the competitive and financial impact can be severe.

Business Continuity and Disaster Recovery

In 2020, over 700,000 businesses in the U.S. were forced to close temporarily due to the pandemic. For manufacturers, disruptions can come from cyber incidents, equipment failure, power outages, natural disasters, or supply chain breakdowns. Yet one in five SMB executives still report having no business continuity and disaster recovery plan in place.

Manufacturing disaster recovery requires specific considerations beyond standard IT recovery:

• Production line dependencies and the sequence in which systems must be restored
• Equipment that requires calibration or warm-up time after an outage
• Supply chain communication protocols so vendors and customers know your status
• Inventory and order management continuity during extended disruptions
• AI-driven predictive maintenance that identifies potential equipment issues before they cause unplanned downtime

Test your DR plan at least annually, and make sure all employees, whether on the production floor or in the office, know their roles in an emergency. For comprehensive DR planning guidance, see our backup and data recovery guide for Chicago businesses.

The Manufacturing IT Talent Shortage

According to Deloitte and the Manufacturing Institute, approximately 87% of manufacturing companies report difficulty finding qualified IT staff, particularly professionals who understand both corporate IT systems and industrial OT protocols like PLC programming and SCADA management. The challenge of finding staff capable of managing 24/7 IT uptime and specialized production floor machinery simultaneously is one of the most significant barriers to improving manufacturing cyber resilience.

This talent gap means many manufacturers are running critical systems without adequate monitoring, patching, or incident response capabilities. Some are increasingly utilizing upskilling programs to train current employees on new digital tools, but closing the gap internally takes years.

For most manufacturing organizations with 25 to 250 users, the practical solution is not hiring a full internal IT security team. It is partnering with a managed IT services provider that understands manufacturing environments, can manage both IT and OT security, provides 24/7 monitoring and detection and response, and builds cybersecurity into every layer of your technology management from day one.

Stop Treating IT as a Cost Center

The manufacturers who treat IT as a cost to minimize are the ones who end up paying millions when a ransomware attack halts production, a legacy system failure corrupts inventory data, or a supply chain breach exposes customer information. The manufacturers who treat IT as operational infrastructure, managed with the same rigor as their production equipment, are the ones who maintain uptime, protect their intellectual property, and scale without disruption.
