How safe is our data?

I am familiar with the previous versions of Cybertracker that were downloaded on a trimble, but now that the system is online - how safe is our data? Where is it stored, and can it be hacked?

Generally, the security of online systems is well understood. CyberTracker Online has been built with best practices. The chances of being hacked certainly increase as you go online, so if that is maximally concerning, then you can still use Classic as an offline system.
