Why Tbox Systems Are Built with Cyber Security at Their Core

In an industry that’s increasingly connected, the line between operational technology (OT) and information technology (IT) has become dangerously thin. At Tbox, we don’t take chances. Every system we deploy is engineered with one simple rule — security first, always.

Designed for Containment

Our RFID, vending, and smart storeroom solutions are designed to operate as self-contained environments. We don’t rely on constant cloud connectivity or open internet access. Instead, our systems run on local Ethernet networks, isolated from external connections and segregated from corporate IT systems.That design choice alone eliminates the majority of cyber threats most industrial systems face.

Hardened from the Ground Up

We use a layered approach to security:

• PLC-based control systems for critical functions – small, tightly defined, and nearly impossible to exploit remotely.

• Android-based kiosks, configured for on-premise use only – no Wi-Fi, no Bluetooth, no cloud, no open ports. Each unit is locked to a single function and runs in secure kiosk mode, verified boot, and SELinux enforced.

• Strict network zoning – dedicated VLANs, firewalls, and default-deny rules across all communication pathways.

• No dual-homing, no shortcuts – every interface and connection is deliberate, logged, and controlled.

Our approach keeps control systems separate, contained, and predictable — which is exactly how cyber security should be done in manufacturing.

Managed Updates and Access

All Tbox devices are subject to a defined patch cycle, controlled firmware updates, and tamper-evident configurations. Remote access, where required, is brokered through secure gateways with time-limited, auditable sessions. No open TeamViewer links, no uncontrolled VPNs.

Built for Real-World Resilience

Cyber security isn’t just about firewalls and passwords. It’s about reducing attack surfaces and limiting exposure. By removing unnecessary connectivity and simplifying the software stack, we dramatically reduce risk without compromising capability.
