With our Exchange 2010 SP3 servers hosted on premise and having subscribed to cloud based email secure gateway services with likes of 'Symantec' or 'Mimecast' and having end point malware protection on user workstations using the likes of ' McAfee' or 'Sophos', what are the residual threats that would be mitigated by deploying another Malware protection technology component on the base exchange 2010 server itself?
Is it needed?
If it is, then I see that there are various players operating in this area with the likes of ' McAfee Security for Microsoft Exchange 8.0.0' and ' Symantec Mail Security for Microsoft Exchange (doesn't seem to support Exch 2010 SP3 though)'. Which one does the community recommend? Also, is there is a native Microsoft product in this area?
