The Ghost in the Machine: Rogue Cellular Threats in Critical Infrastructure

Organizations rely on VPNs, EDR, ZTNA, and firewalls to protect critical systems. But what if the threat is already inside?

This white paper reveals how undocumented cellular transmitters — embedded in devices like solar inverters and EV chargers — bypass conventional security. These rogue components evade asset inventories, call home undetected, and move laterally across your infrastructure.

We detail how embedded transmitters have been discovered in critical sectors and why traditional tools are blind to their presence. From energy and manufacturing to defense and pharma, no vertical is immune.

ColorTokens Xshield™ helps contain these threats through intelligent microsegmentation — stopping the blast radius before it spreads. Xshield delivers:

• Lateral Movement Control
• Policy Enforcement Without Agents
• Real-Time Threat Identification
• Operational Continuity with Minimal Disruption
• Visibility Across OT, IoT, and Cyber-Physical Assets
