Yes.  The Purezone app supports connecting to Wi-Fi network SSIDs that are hidden and not broadcasting the SSID.

During initial Purezone setup, when you are at the step where you are asked to select your Wi-Fi network, and the network SSID does not appear because it is hidden, do the following:

1. "Scanning for Wi-Fi networks" will appear and a list of Wi-Fi network SSIDs will be displayed
2. Scroll down to the bottom of the list and choose "Other"
3. Enter the Network name (SSID)
4. Enter the Password
5. Tap Join

Note:  If you incorrectly enter the Network name (SSID) or Password, the error "Connection failed - Connection to WiFi failed, please try again" will appear.
