Telematics is the use of onboard sensors, GPS, mobile networks, and software to collect vehicle data and send it to remote systems for tracking, diagnostics, dispatch, maintenance, or insurance. In connected fleets, telematics links vehicles to cloud platforms and operators in near real time.
From a cyber-security perspective, telematics matters because it creates a bridge between physical vehicles and digital services. That bridge can be attacked through weak authentication, exposed APIs, insecure mobile apps, unpatched devices, or compromised suppliers. Attackers may try to alter location data, disrupt fleet operations, or abuse remote management features. Defenders use strong identity controls, encryption, network segmentation, logging, and update management to reduce risk. In practice, telematics is both an operational advantage and a sensitive attack surface, especially when safety-critical systems depend on remote commands and trusted telemetry.
