AI Agents in OT: How Shadow AI Creates Operational Security Risk

AI agents may already be operating in OT environments through trusted users, devices, and authenticated sessions. This “shadow AI access” can create operational and security risk, but strong identity and access controls, least privilege, and zero trust can help reduce its impact.

How Viridor Gained Visibility, Control, and Speed Across a Distributed OT Environment

When AI Cyber Threats Evolve Faster Than Critical Infrastructure Can Adapt

AI-enabled cyber threats are evolving faster than critical infrastructure can safely adapt. Following OpenAI’s recent call for collective cyber defense, we examine the implications for OT security and explore how strong identity and access controls can protect legacy and hard-to-patch systems without disrupting essential operations.

The Overlooked OT Security Risks Inside AI Data Centers

TrendAI researchers identified thousands of internet-exposed cyber-physical devices near U.S. data centers. Their findings underscore the importance of securing not just servers and networks but also the operational systems and remote access pathways that keep AI workloads running.
