AI and OT: Hype or Help?
Artificial Intelligence has become an essential tool in building Smart Factories. However, utilizing AI requires connecting systems to the internet, which in turn exposes them to a wider variety of cyber threats. This is where OT security monitoring systems offered by companies such as Nozomi Networks become crucial.
Traditionally, factory equipment operated on separate, isolated networks. But with the shift toward Smart Factory initiatives powered by AI, these systems are now being connected to standard LANs and gaining internet access. As a result, solutions by companies like Nozomi—which monitor the interface between operational technology devices and the network—have become increasingly valuable.
With the introduction of AI to operational technology management, it’s worth taking a moment to think about how it affects operational technology security—specifically where it’s already helping, where it adds real value, and what it can’t actually do yet.
What AI Is Actually Doing Today
In the context of smart manufacturing, AI is making significant progress in automating factory workflows. It helps coordinate production lines, manage inventory, and optimize scheduling. This efficiency gain, however, comes at a cost. Connecting these systems to the internet opens up new points of vulnerability that didn’t exist when factory networks were isolated.
This is where monitoring tools come into play. AI can help establish a baseline of normal behavior across connected operational technology environments and flag unusual patterns that might indicate a problem. This kind of proactive monitoring strengthens operational technology cyber security by giving security teams more context and quicker insight into potential issues.
AI can also reduce alert fatigue. Instead of overwhelming teams with noise, it filters out routine activity and highlights what’s truly important. For lean teams already managing complex environments, that targeted support can make day-to-day operational technology management more efficient.
Where AI Adds Real Value
Many organizations are seeing the impact of expanded connectivity, but lack the staff to match. The operational technology division is under pressure to monitor more systems with fewer people, while the demand for OT security jobs continues to outpace supply.
In many smart factories, AI has reduced the need for traditional operator roles, but that operational efficiency brings new cyber exposure. As systems become more connected, the cost savings are often redirected toward enhanced monitoring solutions like Nozomi, which help protect the infrastructure those roles once supported manually.
These benefits are especially valuable as organizations look to build a modern OT security framework—one that emphasizes resilience over reactivity. AI makes operational technology security more scalable without adding more complexity.
What AI Can’t Do (Yet)
Despite its value, AI can’t do everything. It cannot make up for weak segmentation, legacy systems, or unclear policies. And it certainly can’t replace the institutional knowledge your teams already have, meaning OT cyber security isn’t just about automation. It’s about knowing your systems, understanding their risks, and making informed decisions about how to protect them.
To make AI effective in this role, the foundation still matters. Organizations need regular OT security assessments, ongoing OT security training, and a flexible OT security framework. Only then can AI function as part of a broader OT security service—one that strengthens the entire environment rather than just automating a few tasks.
AI is becoming an essential part of smart factory automation and operational technology cyber security, but it is still just one piece of the puzzle. When paired with the right expertise and supported by a clear strategy, it can help OT teams move faster, respond smarter, and build systems that are resilient by design.
For organizations building for the long-term, success starts with people, strategy, and clear expectations. Not hype.
At SYSCOM, we help organizations spot the hype and build for the long-term. Whether you’re starting with an OT Security Assessment or looking for a reliable partner through our Managed OT Security Service, we’re here to help you take OT security seriously and build resilience that lasts.
