By default, the iFolder enterprise server is configured for shared iFolder access. Client/Server communication is not through SSL. All data is sent to the server in the clear. For most deployments, this setting is used for high performance. This setting can be changed during the simias-server-setup configuration for iFolder.
If you disable SSL for client/server communications, you should use a VPN (virtual private network) for communications over wireless networks and outside the firewall. For information, see Section 4.3, Securing Communications with a VPN If SSL Is Disabled.
