Mark,
Thank you for inquiring about Cisco Jabber. I recommend you review this (Cisco Jabber - Cisco Systems) for general information, as well as secure deployment. As you know, Jabber is available for a number of platforms and mobile devices, and you will find information for each there.
Also, you can check out the Cisco Security Community Security
If you don't find what you are looking for, then please post back to this thread with additional questions.
Hope this helps.
