Does Antivirus for Mac OS meet the following reqirements?

Hi,

I am researching on the antivirus products for Mac available in Market for our entrepirse environment.

I was wondering if SEP for Mac(latest version) meet the following requirements

1. Customizable to meet our needs?
2. Protected against end user changes?
3. Accepted list for the Cisco ASA VPN
4. Dedicated to Mac? Or for  both Mac and Windows. For example, if you use Parallels with a Windows virtual machine on your Mac, files in shared folders on your Mac will be scanned for both types of threats.
5. What are the supported Mac Operating Systems?
6. Does it Update with Proxy?

Thank you
