Client has a VPN hotspot on her phone. She wants to know if she connects her clover flex to her phones hotspot if the clover will be using the vpn. She travels a lot and wants to make sure the flex is secure.
This is more a question about how tethering works on the phone. If it routes hotspot traffic through the VPN then yes, the Clover device connected to the hotspot will be using the VPN. Clover devices aren't any different than mobile phones, tables, laptops or whatever else you might be tethering to the hotspot.
A little googling on the topic implies that hotspot traffic is generally not tunneled through a VPN on a phone. Or at best, it's an open question and depends on how this things are configured. I am not an expert here by any means.
When you create a hotspot you can configure what sort of wifi security you want. As long as you're use WPA2 and not sharing the passcode with untrusted parties using your own hotspot is secure as using any other wifi network that is similarly configured. Clover devices won't connect to insecure open, and WEP-based wifi network anyway.
It's also not clear how using a VPN would enhance the security. All communications to and from the Clover device are encrypted. While I'd always suggest using non-public networks (like your hotspot, if it's configured as I said above), using a Clover device on a public network isn't particularly unsafe either.
