Ransomware Threats in Manufacturing: A Call to Action by Secomea

In the ever-evolving landscape of cybersecurity, one of the major threats currently plaguing the manufacturing sector is ransomware. Recent reports signify a troubling rise in ransomware incidents targeting manufacturers and industrial suppliers. With the stakes continuously escalating, industry leaders must reconsider their approaches to remote access in operational technology (OT) environments.

Secomea, a notable provider of secure remote access solutions tailored for industrial networks, has articulated the pressing need for organizations to reassess how they manage third-party remote access across production settings. According to their insights, operational continuity is vital, yet ensuring robust cybersecurity, compliance, and efficient vendor access control is equally crucial.

The Shift in Focus

Knud Kegel, CTPO at Secomea, underscores that the traditional focus has primarily been on preventing attackers from breaching systems. However, Kegel argues that organizations often neglect a critical aspect: the management of access once an adversary gains entry. He explains, "In manufacturing environments, remote access for maintenance and support is indispensable. The challenge lies in ensuring that this access is controlled, temporary, and sufficiently monitored."

As facilities increasingly depend on machine builders, system integrators, and service providers to support operations remotely, the potential vulnerabilities associated with persistent access and shared credentials have become clear. These factors combined create fertile ground for attackers, enabling them to maneuver through environments following an initial breach.

The recent surge in cyber-attacks on manufacturing companies illustrates the importance of balancing operational accessibility with stringent security measures. Many businesses underestimate the potential damage caused by lax oversight of remote access, resulting in an alarming spike in vulnerabilities.

Essential Measures to Mitigate Risks

Secomea recommends focusing on three fundamental areas to enhance the security of OT environments:

1. Reduce Standing Access: Organizations should grant vendor access strictly as necessary and revoke it once tasks are completed. By limiting access windows, manufacturers can significantly minimize opportunities for misuse and unauthorized activities.

2. Improve Visibility and Accountability: Detailed logging of who accesses systems, the timing of connections, and actions taken is crucial. Establishing thorough audit trails not only aids in compliance but also facilitates effective investigations and incident response.

3. Prepare for Containment: When suspicious activities emerge, it’s imperative for security teams to have systems enabling them to isolate affected assets swiftly and prevent disruptions from spreading across production lines.

Effective governance of OT access hinges on implementing controls such as least-privilege access, just-in-time vendor access, comprehensive audit capabilities, and rapid containment mechanisms. These governance strategies aim to achieve a delicate balance between managing cyber risks and maintaining undisturbed operational continuity.

Practical Steps Towards Cyber Resilience

As manufacturers analyze their cybersecurity resilience frameworks, Secomea urges brands to ensure they incorporate specific controls and processes into their systems:

• - Just-in-Time Vendor Access: Prioritize temporary access over persistent connections to mitigate vulnerability.
• - Approval-Based Workflows: Implement rigorous approval processes to ensure only authorized personnel can access critical systems.
• - Least-Privilege Permissions: Limit user and vendor permissions to the bare minimum necessary to perform their tasks.
• - Audit Trails for Investigations: Establish comprehensive logs that assist with compliance and forensic evaluations.
• - Rapid Asset Isolation Capability: Develop the ability to quickly quarantine affected systems in response to security incidents.

As Kegel notes, the conversation surrounding cybersecurity is shifting from merely facilitating remote access to governing how that access is managed. Manufacturers don’t need to reduce connectivity; instead, they need enhanced governance of that connectivity. Organizations that can effectively limit, monitor, and contain access are better positioned to mitigate the operational impact during incidents.

Kegel concludes, "Ransomware resilience in manufacturing increasingly depends on the management of remote access to OT systems. Just-in-time vendor access, real-time visibility into remote sessions, and efficiency in asset containment are becoming fundamental cornerstones of cybersecurity in this sector."

Secomea’s Commitment

Secomea has established itself as a significant player in delivering secure remote access solutions for industrial networks. With over 8,000 manufacturers globally relying on Secomea for robust connectivity, their focus on effective governance of vendor access, the application of zero-trust principles, and enhanced visibility into OT access activities has helped support secure collaborations across the manufacturing landscape.

Secomea's recognition as a Representative Vendor in the Gartner® Hype Cycle for CPS Security, 2026, further accentuates their credibility in this crucial field. As organizations gear up to tackle the risks posed by ransomware, the need for steadfast cybersecurity measures in manufacturing is at an all-time high.
