we're planning to install PGP Desktop whole disk encryption to 30 clients. Having unmanaged clients are okay with us...however we still want to know what are the advantages and disadvantages (if there's any) of having a PGP Universal Server
thanks
Please see http://www.symantec.com/universal-server
If you don´t trust your users, or you think they can mess up PGP, you should use Universal server so you configure encryption settings for them
