Geotab GO8

GO8 Device

GO8 is a small yet extremely powerful telematics measurement tool. Similar to the GO7® before it, the GO8 offers state-of-the-art GPS technology, g-force monitoring, GEOTAB IOX® expandability, and engine and battery health assessments, with the added feature of communicating on the LTE network.

Vehicle Tracking

Using Geotab’s patented tracking algorithm, the GO8 accurately recreates a vehicle’s trips and analyzes its incidents. Moreover, the GO8 offers in-vehicle alerts to instantly notify drivers of infractions and — with hardware Add-Ons — the ability to provide live coaching to drivers relating to their on-road performance. The GO8 is a truly Plug-&-Play technology — it does not require a dash-mounted antenna or any splicing of wires.

Security

Geotab platform security is designed for end-to-end protection of your data.

Key implementations include:

  • GO device and network interfaces use authentication, encryption, and message integrity verification.
  • GO devices are individualized. Each device uses a unique ID and non-static security key, making it difficult to fake a device’s identity.
  • Over-the-air updates use digitally-signed firmware to verify that updates comes from a trusted source.
  • Geotab uses independent third-party experts to validate the platform from end to end.
  • FIPS 140-2 validated by NIST (certificate #3371)
