The Benefits of Network Monitoring for Industrial Digitalization
Industrial Digitalization
Today, manufacturing is powered by thousands of connected devices, massive computing power and artificial intelligence. These advances enable manufacturers to adopt flexible, built-to-order production methodologies that include automated workflows and real-time performance monitoring. Together they improve efficiency, reduce errors and cut costs, but with these benefits comes increased cyber risk.
Industrial digitalization is characterized by the integration of computation, networking and physical processes, which bring clear business advantages. It has also led to highly complex, heterogeneous manufacturing networks due to the convergence of enterprise and manufacturing assets and increased use of Internet of Things (IoT) devices. As a result, manufacturers are operating with increased cybersecurity and operational risk that can lead to downtime if they are not top-of-mind in a holistic cybersecurity and digital transformation strategy.
Threats and Needs
In 2023, a leading boating manufacturer, Brunswick, fell victim to a cyber attack that caused its operation to be down for nine business days causing losses of $13 million. The company was forced to stop operations in some locations while experts and law enforcement dealt with the incident. While ransomware was not officially blamed, security experts believe it to have been the case.
The knock-on effect of cyber attacks on the supply chain cannot be underestimated. In 2023, semiconductor maker, Applied Materials, had a very similar security event occur in its supply chain when its supplier, MKS Instruments, was targeted in an attack. Applied Materials said it cost the company upwards of $250 million from the incident.
However, cyberattacks are by far not the most imminent threat to the manufacturing industry. Despite the noise from the media, the likelihood of a successful attack against industrial control systems (ICS) is relatively low. On the contrary, cyber incidents happen daily. They include small to major network or process disruptions due to misconfigurations, erroneous commands and operations, software errors and device failures – none of them intentional, but nevertheless all impacting the asset owner’s bottom line.
To effectively protect the network and avoid downtime, asset owners must be able to detect all these threats in a timely manner. When choosing a strategy to implement, guidelines such as the NIST Cybersecurity Framework and IEC 62443 can provide valuable advice on how to improve the overall cybersecurity of industrial networks.
The figure on page 4 provides a good overview of the industrial automation threat landscape, including the frequency and impact of threats and problems. These operational and networking threats are detected daily at most of our manufacturing customers.

Compliance as an Opportunity: Transforming Risk into Resilience
Today’s manufacturing is a constant race to be faster, smarter, and more connected, to stay competitive and ahead of the curve. But all it takes is one small cyber hiccup to bring everything to a halt. To thrive in this complex threat landscape, in addition to speed and connectivity, a business needs the ability to absorb a hit and keep moving forward. Organizations can transform compliance from a regulatory burden into a driver of smarter decisions, enabling them to identify and address issues early, before they escalate into costly incidents.
To build that kind of operational resilience, organizations need a clear plan and a practical framework to follow. The NIST Cybersecurity Framework (CSF) offers exactly that, core functions and recommendations that help establish visibility, enforce control, and improve response across the industrial environment.

Identify
When threats hide in blind spots, visibility becomes your first line of defense to identify vulnerabilities and exposures. Forescout builds and maintains a real-time inventory of assets, systems, and services across IT and OT environments, mapping communications, exposing dependencies, and tracking changes over time. Powered by proprietary threat intelligence and a combined security and operational risk score, the Vistaro™ platform makes identifying exposure and prioritizing remediation by impact or exploitability faster and more effective.
- Native support for IT and OT systems, both managed and unmanaged, eliminates silos, reduces hidden threats, and avoids costly third-party integrations, data duplication and false positive.
- Combined security and operational risk scoring provide a more accurate view of exposure based on impact, likelihood, and business criticality.
- Enriches asset and threat data through integration with third-party tools, enhancing vulnerability detection, tracking configuration changes, and monitoring device risk posture over time.

Protect
How can you secure what you can’t control? As connected assets grow and identities move beyond traditional boundaries, organizations need more than a static approach. Forescout enables dynamic, policy-based control over access, identity, and behavior, making sure that only trusted users and devices can interact with critical systems. This real-time enforcement enhance data protection, supports least-privilege access, and builds the foundation for a resilient, zero-trust architecture. Most importantly, it works with your existing security stack, maximizing current investments while extending control across the entire enterprise.
- Identity and access management with risk-based policies, dynamic segmentation, and least-privilege principles to limit exposure and lateral movement.
- Asset and communication baseline with continuous posture and compliance validation to monitor behaviour, configuration, and integrity changes that could indicate compromise or policy drift.
- Zero trust segmentation and data flow visibility to restrict access based on trust boundaries and detect unauthorized communication, exfiltration attempts, or policy violations.
- Device lifecycle management to track configuration changes, block unauthorized software, and enforce security baselines across asset types.
