Hi Meghan,
Great question! Knowing where your traveller is all the time whilst on official business is a huge duty of care issue facing organizations - penalties for not demonstrating this duty of care are now both civil and criminal (in Australia anyway). I use International SoS in conjunction with my Travel Management Company. Each time a PNR is raised for international travel the traveller receives a Pre Trip Country Specific Advisory which directs them to the online Travel Risk training if they haven't completed it in the last 12 months. It also requires them to press a button acknowledging they have read and understood the advisory. I get regular exception reports on who hasn't "pressed the button" and follow them up.
Best of all I have Travel Tracker with International SOS - it tells me via their itinerary where my travellers are anytime and allows me to contact them in the case of an incident - such as the Paris bombings a few years back. Concur also offers a very similar product - well worth looking into.
Kind regards
