Welcome back to Protect It All! In this episode, host Aaron Crow sits down with longtime friend and OT cybersecurity veteran Brian Proctor for a deep dive into the current state—and future—of the OT cyber landscape. Together, they trade stories from the front lines, reflecting on how their early experiences as asset owners shaped their passion for innovation and helping critical infrastructure run safely and securely.

Brian, whose career spans roles from OT engineer to startup co-founder, opens up about his journey—highlighting his drive to push the boundaries of traditional OT security and the evolution of key industry technologies. The conversation explores everything from the persistent lack of innovation in OT, to AI’s growing role in tackling the daunting challenges of risk reduction, visibility, and scaling assessments across sprawling environments.

If you’ve ever wondered how new tech like AI is reshaping industrial cybersecurity, why “we’ve always done it this way” just doesn’t cut it anymore, or how organizations can realistically stay ahead without breaking the bank, this episode delivers honest insights, practical advice, and a look toward an exciting, if sometimes daunting, future.

So grab your headphones and settle in as Aaron and Brian share stories, hot takes, and strategies designed to protect it all—because in critical infrastructure, the stakes have never been higher.
