Company vehicles, and in particular the personal vehicles of senior directors, are a frequently overlooked element of corporate TSCM programmes that focus heavily on office premises while leaving the time directors spend travelling — often conducting calls and discussing confidential matters — entirely unaddressed. A vehicle is, in some respects, an easier environment to compromise than an office: access is often less controlled, particularly during servicing or valeting, and the confined space makes a planted device disproportionately effective relative to the same device in a large room.
Executive Vehicles
Vehicles used regularly by senior directors for both business and personal travel frequently host confidential calls, conversations with other directors during shared journeys, and in some cases conversations recorded via hands-free systems that are themselves a potential vector for compromise if the vehicle’s infotainment system has been tampered with. We recommend vehicle sweeps as a standard component of any executive-level TSCM programme, conducted at the same cadence as office sweeps and specifically following any period during which the vehicle was out of the director’s direct control — servicing, valeting, or storage.
Fleet Vehicles
Where an organisation operates a broader vehicle fleet used by multiple staff, the TSCM consideration shifts somewhat from confidential conversation interception toward GPS tracking and movement monitoring, particularly relevant where competitors or other interested parties might benefit from knowledge of delivery routes, site visits, or meeting patterns. Periodic sweeps of fleet vehicles, particularly those used by sales, business development, or site survey staff who visit sensitive locations, are a proportionate measure for organisations where vehicle movement patterns themselves carry commercial value.
GPS Trackers
GPS tracking devices are typically magnetically mounted to the vehicle’s underside, wheel arches, or chassis, or in more sophisticated installations, hardwired into the vehicle’s OBD port to draw power directly from the electrical system. A vehicle sweep should include physical inspection of all externally accessible mounting points using inspection mirrors and torches, together with RF detection to identify any device actively transmitting location data, and inspection of the OBD port and surrounding wiring for unauthorised connections.
Listening Devices
Audio devices in vehicles are most commonly concealed within interior trim, beneath or behind seating, within the vehicle’s own infotainment or hands-free system, or in aftermarket accessories such as phone mounts or chargers introduced without the director’s knowledge. A thorough vehicle sweep addresses the interior using the same NLJD and physical inspection techniques applied to office environments, with particular attention to any aftermarket equipment that was not part of the vehicle’s original specification.
Travel Security
Vehicle TSCM should be considered alongside, rather than instead of, broader executive travel security: awareness of surveillance during international travel, the security of devices and documents carried during travel, and the risk profile of meetings conducted in third-party venues such as hotels, where the organisation has no control over the room’s TSCM history. We address venue-specific considerations for hotels and conference venues in our article on temporary office and event bug sweeps.
