The industrial cybersecurity landscape is shifting dramatically as we navigate 2026, with experts warning that traditional detection-first approaches are falling short against AI-driven threats. At the S4x26 conference in Miami, industry leaders highlighted how autonomous attacks are forcing a fundamental rethink of OT security strategies.

Benny Czarny’s insights from the conference really hit home – we’ve been playing defense for too long while attackers are increasingly leveraging AI to probe our systems faster than we can detect them. The industrial cybersecurity community needs to pivot from reactive detection to proactive prevention, especially as our manufacturing floors become more connected and vulnerable.

IoT Expansion Brings New Opportunities and Risks

Speaking of connectivity, Nordic Semiconductor’s massive expansion of its cellular IoT portfolio at MWC 2026 is worth paying attention to. Their new nRF92 and nRF93 series, along with enhanced nRF91 devices, are targeting the evolving LTE-M and NB-IoT landscape. For plant engineers, this means more ultra-low-power options for connecting everything from sensors to predictive maintenance systems.

But here’s the catch – more connected devices mean a larger attack surface. As we embrace these new IoT capabilities for industrial automation, we need to bake security in from day one, not bolt it on later.

The Data Challenge in Energy and Manufacturing

One story that particularly resonates is the reality check about AI in energy companies. Before they can leverage AI for pipeline fault prediction or drilling optimization, they need to solve a fundamental problem – their most valuable data isn’t digitized. It’s sitting in filing cabinets, scattered across shared drives, and buried in handwritten technician logs.

This mirrors what I see across manufacturing. We’re all excited about Industry 4.0 and smart factories, but many plants are still struggling with basic data collection and organization. You can’t optimize what you can’t measure, and you can’t measure what you haven’t digitized.

Meanwhile, igus continues its impressive transformation from a motion plastics company to a robotics powerhouse. Their RBTX division becoming their third-largest segment shows how traditional component suppliers are evolving to meet changing automation needs. It’s a smart play – who better to understand bearing requirements in robotics than the company making the bearings?

As we face increasingly sophisticated cyber threats while expanding our connected ecosystems, the question becomes: Are we moving fast enough on security integration, or are we setting ourselves up for the next major industrial cyber incident?
