IM Filtering on Blue Coat ProxySG

What kind of IM security functionality is available from the Blue Coat ProxySG?

Administrators can control IM functionality such as:
- Block File Transfers;
- Search for keywords;
- Limit chatroom access on a user or global basis;
- Instant Messaging messages can be monitored or logged (your boss is watching) =]

As a proxy the BC ProxySG can:
- Allow selected protocols;
- Establish authentication rules for using IM services;
- Allow or deny attachments by file type;
- Allow or deny chat activity;
- Filter Keywords (my boss is the best);
- Block access to IM services by user or other means.
- Block encrypted IM services, because you do not know what information is being transmitted.
