Ep 54: Simplifying OT Cybersecurity: Tools and Strategies for Non-Experts in Critical Infrastructure with Steve Kiss

In this episode of Protect It All, host Aaron Crow sits down with Steve Kiss, founder and CEO of IPMeter, for an eye-opening discussion on the future of OT (Operational Technology) and IT cybersecurity. With over 25 years of hands-on experience, Steve shares his journey from network engineering to designing practical cybersecurity tools for real-world OT environments.

They dive into the unique challenges faced by operators in sectors like wastewater treatment, building management, and power utilities—where frontline professionals often shoulder critical cybersecurity responsibilities without formal training or extensive resources. Steve and Aaron emphasize the urgent need for simple, scalable, and reliable tools that empower these “full stack” operators to secure critical infrastructure effectively.

From bridging the IT-OT divide to managing legacy system risks and improving procurement practices, this conversation offers actionable insights for municipalities, utilities, and smaller organizations aiming to take greater ownership of their cyber defenses. Packed with real-world examples, strategic advice, and a touch of industry humor, this episode is essential listening for anyone focused on protecting essential services and strengthening community resilience.
