If you see an alert regarding a public WiFi network vendor, then the network in question tried to decrypt the encrypted traffic coming from your device. As a result, sessions and passwords could be seen in clear text.
There are two types of threats here, and both can lead to email theft, access to other corporate resources, device lock down, user impersonation, and in some cases even phone tapping.
We take such threats seriously, and will continue to address them on a regular basis. One other unique advantage of SEP Mobile is to secure this communication without compromising connectivity.
