TL;DR: The partnership with Raglan combines software-defined vehicle architecture and operational technology monitoring to harden military and government vehicles against cyber and electronic warfare threats, according to Shift5, extending security into vehicle control systems and mission platforms. The important shift is that fleet security now has to cover trusted control logic, telemetry and resilience as well as traditional vehicle hardening.
Editorial analysis by NHI Mgmt Group, based on content published by Shift5: “Shift5 and Raglan Partner to Deliver Next-Generation Security for Military and Government Vehicles”.
Key questions
Q: How should defence fleets govern software-defined vehicle control paths?
A: Treat the control path as privileged infrastructure.
Q: What happens when vehicle telemetry cannot be trusted during operations?
A: Operators lose confidence in the vehicle’s state, which can be as damaging as a direct compromise.
Q: Why do software-defined fleets need OT-style access control?
A: Because the systems now include maintenance, diagnostics, and control interfaces that can change physical behaviour.
Practitioner guidance
- Define software-defined vehicle trust boundaries Map which vehicle functions are safety critical, which are updateable, and which teams or systems can change them.
- Segment maintenance and control access Separate diagnostics, fleet management, and mission operation access so that no single account or interface can alter control logic without oversight.
- Baseline vehicle behaviour under contested conditions Record normal command, sensor, and performance patterns so that drift can be detected when external signals or links degrade.
Bottom line: Software-defined vehicle programmes create a new governance problem because control logic, diagnostics, and telemetry now sit inside the security boundary.
