SAV versus Parity Bit9??

Hey ya'll,
 
I'm a couple months new to the current company I'm with and although I'm not on the project have been trying to get input from those that may have some experience, knowledge or an opinion on the subject. :-)
 
The company currently has a project going to 'replace' SAV with the Parity Bit9 product.
 
Some have concerns about this...
 
Does anyone here have an opinion or experience with Bit9 that you would like to contribute?
 
Thanks and I appreciate in advance anything you have to share!
