Can your plant stay connected and completely secure?

In this episode of Protect It All, host Aaron Crow teams up with Lior Frenkel, CEO and co-founder of Waterfall Security, to explore how industries are rethinking OT cybersecurity in the age of ransomware and AI-powered attacks. Together, they break down why traditional firewalls can’t fully protect industrial control systems and how unidirectional gateways (data diodes) are redefining safety for everything from nuclear plants to casinos.

You’ll learn:

• What data diodes really are and how they physically block inbound attacks.


• Why “air gaps” are no longer enough for modern connected environments.


• How remote-access tools like HERA are enabling secure operations.


• Real-world stories of industries upgrading defenses without losing efficiency.
  
  

Whether you manage critical infrastructure, handle OT security, or just want to understand how cyber-physical systems stay safe, this episode will give you a new appreciation for data flow, digital risk, and resilience.

Tune in to discover the future of secure connectivity - only on Protect It All.
