As usual, the answer is "it depends".

Before the remote client can communicate with the SQL server (via an ODBC connection), first a network connection has to be established. Often, this is done by creating a "virtual private network" (VPN - see Wikipedia for an overview). If your network people have set up a VPN between the two endpoints then any traffic carried through that VPN is transparently encrypted/decrypted with pretty good algorithms, so you don't need to worry about anyone in the middle sniffing the data stream.

Come to think of it, just about all modern technologies used to establish persistent connections through the Internet are very security-conscious so it's actually unlikely that a non-encrypting technology is being used. Nevertheless, it's a good question and one well worth asking of your network people.
