Cybersecurity has become a serious concern for manufacturers in recent years. The rise in ransomware attacks targeting both operational technology (OT) and information technology (IT) systems has made security a top priority. These attacks don’t just put data at risk, they can shut down production, damage equipment, and cause major financial loss. Many manufacturers are still managing OT and IT as two separate parts of their business. In this article, we’ll explain the difference between OT and IT, why attacks are on the rise, and how a specialized MSP can help protect your business from threats.

What Is OT and IT?

Operational Technology (OT) refers to the hardware and software systems used to monitor and control physical devices in a business. This includes things like industrial control systems (ICS), programmable logic controllers (PLCs), SCADA systems, and other machines used in manufacturing, energy, and utilities.

Information Technology (IT) covers computers, servers, and software used to manage data, communicate, and run business operations. This includes email systems, databases, file storage, and office networks.

According to Wikipedia, OT is focused on managing industrial operations, while IT is centered on data processing and communication. In the past, these systems were kept separate. But today, more manufacturers are connecting them to gain better efficiency and insights.

However, this connection also creates new risks.

Rising Risks in 2024: OT Is Now a Target

In 2024, cybersecurity researchers reported an increase in ransomware attacks directly targeting OT systems. Attackers are no longer just stealing data, they are shutting down equipment and halting production lines.

A report by Dragos, a leader in industrial cybersecurity, shows that ransomware gangs have become more focused on disrupting manufacturing processes. Once inside a network, they don’t stop at the IT side. They move deeper into OT systems, causing physical damage or shutting down plants until a ransom is paid.

This has raised concerns not only about business loss but also safety. Disrupting an OT system can lead to real world harm such as broken machinery, unsafe working conditions, or even environmental damage.

The Pressure to Meet Cybersecurity Standards

Manufacturers now face growing pressure to meet industry standards and government regulations. Some of the most important cybersecurity frameworks for OT and IT environments include

• ISA/IEC 62443

This is a standard specifically designed for securing industrial automation and control systems.

• NIST 800-82

Guidelines for securing ICS systems from the National Institute of Standards and Technology.

• ISO 27001

A general information security standard that also applies to industrial systems when connected to IT networks.

Failure to comply can lead to fines, lost contracts, or legal issues. More companies, especially in automotive, aerospace, and energy, now demand that their suppliers follow strict cybersecurity rules.

The IT and OT Convergence Challenge

As manufacturers connect OT and IT systems, they gain efficiency, but also create new risks.

Legacy OT Systems Are Not Built for Security

Many OT devices were designed 10 to 20 years ago. They were not made to connect to the internet or open networks. As a result, they lack basic security features such as encryption or user access control.

These systems may be too old to update or replace, and they often use outdated software that attackers can exploit. When these machines are connected to IT networks, attackers can move from a compromised email server to the plant floor all within minutes.

Real World Consequences

Unlike IT systems, which mostly handle data, OT systems control physical equipment. An attack that stops a file server may cause delays, but an attack that disables a robotic arm or conveyor belt can cause injuries, equipment damage, or product loss.

This makes securing OT systems just as important if not more than protecting your IT environment.

How a Cybersecurity Focused MSP Can Help

A Managed Service Provider (MSP) that understands both OT and IT can take important steps to reduce your risk. Here’s how…

Network Segmentation and Monitoring

MSPs can create network “zones” that separate OT systems from IT systems. This way, if an attacker breaks into your IT systems, they won’t automatically get access to your OT equipment.

They also set up 24/7 monitoring to detect suspicious activity across the network. Early alerts can stop a small problem before it turns into a major shutdown.

Secure Legacy OT Systems

Many old OT systems can’t be updated or patched. An MSP can help protect them with workarounds, such as

• Adding multi-factor authentication (MFA) to access control systems.
• Limiting external access using firewalls and secure gateways.
• Making regular backups of critical control software to prevent total loss during an attack.

OT Specific Incident Response

When an OT system is under attack, the response is different from an IT issue. You can’t just shut down or reset machines that could cause damage or injury. A good MSP will have experience responding to OT threats safely. They’ll have a plan that includes isolating infected systems, alerting the right people, and restoring operations quickly with minimal disruption.

Helping You Meet Industry Standards

Cybersecurity frameworks are not optional, they’re now expected. A specialized MSP helps you align with key standards like:

• ISA/IEC 62443: Segmenting networks, managing access, and securing industrial components.
• NIST 800-82: Implementing controls tailored for ICS systems.
• ISO 27001: Organizing your overall security plan and policies.

Documentation and Audits

MSPs assist with risk assessments, regular audits, and documentation required for compliance. They help maintain records of all cybersecurity activities, which can be shown to regulators, partners, or insurance providers when needed.

Reducing Downtime and Saving Money

Downtime in manufacturing can lead to major financial loss, missed deadlines, and damaged equipment. Cyberattacks targeting OT systems make this risk even higher. Investing in the right cybersecurity approach not only improves protection but also helps reduce unexpected outages and long term costs for your business.

The Real Cost of Cyber Attacks

Cyberattacks on manufacturing are expensive. A single ransomware attack can cause

• Production downtime: which may cost thousands per hour.
• Damaged equipment: which can take weeks or months to repair.
• Missed deliveries: leading to canceled orders or broken contracts.

In some cases, even the cost of recovering data and systems is more than the ransom itself.

A Real World Example

A mid sized manufacturer in California suffered a ransomware attack in 2023. Their production line was down for 3 days, costing over $250,000 in lost output and repair costs. They later partnered with a cybersecurity focused MSP who segmented their network, installed better monitoring tools, and updated remote access controls. In early 2024, they were targeted again but this time, the attack was detected and stopped before it reached OT systems.

This kind of prevention shows how an MSP not only helps meet compliance but also saves money in the long run.

Protecting Your OT/IT Future Starts Now

Manufacturers can no longer treat OT and IT as two separate parts of the business. Today’s threats go beyond the office network, they reach the machines on your shop floor. One weak point in your system can put your entire operation at risk. With growing risks and stricter regulations, it’s important to have a partner who understands both sides of the challenge. A cybersecurity focused MSP gives you the tools, experience, and support needed to stay ahead of threats, meet compliance standards, and reduce costly downtime.
