Sreec, thanks for response. Licensing cost of vShield is high, and I don't want to spend that much. My VMs running some applications uses Tomcat, and somehow cause of vulnerability. Customer will be able to upgade Guest OS and application in October 2013.
I have another DMZ Cluster in the same VC, and planning to isolcate VMs creating a seperate vSwith, that will use VLAN from DMZ network.
What you say on this?
Thanks,
Daksh
