AI, OT Cybersecurity & the Critical Infrastructure Crisis We Can't Keep Ignoring

Artificial intelligence is reshaping cybersecurity — but in operational technology (OT), industrial control systems (ICS), and critical infrastructure, the most dangerous threats aren't coming from AI‑powered superattacks. They're coming from something far more basic:

Internet‑exposed systems. Legacy equipment. No asset inventory. Weak controls. Minimal monitoring. And decades of cybersecurity debt.

In episode 57 of Cyber Security America, Joshua Nicholson sits down with Santosh Kaveti, CEO & Founder of ProArch, for a candid conversation about the escalating risks facing water treatment facilities, power grids, manufacturing plants, and other essential services.

Recent attacks on U.S. water systems exposed a painful truth: many PLCs, HMIs, remote access portals, and ICS components are still directly reachable from the internet — no zero‑day required. When those systems control the infrastructure communities rely on, cybersecurity failures become public safety failures.

This isn't just an IT problem anymore. It's a national security problem.

In this episode, you'll learn: Why internet‑exposed PLCs and ICS devices represent one of the biggest OT security breakdowns of our time

How AI can strengthen OT environments through asset discovery, behavioral baselining, anomaly detection, and accelerated response

Why separating IT and OT security is no longer viable for modern critical infrastructure

The hidden risks inside supposedly "air‑gapped" systems that aren't actually monitored or governed

How secure remote access, vulnerability management, change control, and recovery planning can dramatically reduce OT incident impact

Why legacy infrastructure continues to hinder utilities and critical operations

How compliance‑driven cultures create blind spots that undermine true cyber maturity and resilience
