Yes, I mentioned that. However, the cell plan would be a lot cheaper. There shouldn’t be a lot of data coming through.
It would mean exposing it as much as any other device is exposed. It’d have a port open and listening for communication. Honestly, I’m pretty sure it’d be identical to how it is currently. It’s not like sending the communication from the company server is any different than from any other device. Its not connecting directly to the company’s servers. It’s a wireless service. Sure, it needs security measures, but it already needs that.
