Apex One monitors messages and files that users send through instant messaging (IM) applications. Messages and files that users receive are not monitored.
For a list of supported IM applications, see the Data Protection Lists document at:

When Apex One blocks a message or file sent through AOL Instant Messenger, MSN, Windows Messenger, or Windows Live Messenger, it also terminates the application. If Apex One does not do this, the application will become unresponsive and users will be forced to terminate the application anyway. Users do not receive a notification after the application terminates. Inform them of this situation when you roll out your DLP policies.
