Dave Jennings explains where hidden risk lives on the plant floor—and the production-safe steps organizations can take to reduce it.

You can’t defend what you can’t see. 

“It’s always worked” is the most expensive sentence in manufacturing.

Legacy controls. Undocumented workarounds. Vendor connections added one at a time over the years. Most plants have no current picture of what’s actually on their floor, how it’s connected, or where it’s exposed. The system fulfills its requirements—until someone finally looks at it.

Meanwhile, the threat landscape has changed. Manufacturing is now a priority target, and AI is lowering the skill required to disrupt operational technology (OT) environments. The gap between what plants are defending and what’s actually there is widening fast.

In this session, Dave Jennings walks through:

  • The “it’s always worked” patterns that quietly accumulate risk in every plant
  • What we actually find when we assess OT environments—and what it costs clients when no one looked sooner
  • How to gain real visibility into your OT environment without touching production
  • What a practical, fundable path forward looks like
