Q: What's VMware vShield?

A: VMware vShield is a collection of virtual appliances built for the VMware vSphere platform. Its virtual appliances provide security services for vSphere VMs, supporting activities such as firewall protection and anti-malware. They can also provide network edge and gateway services, including DHCP, VPN, NAT, port translation, and load balancing.

Depending on which you've licensed, a vShield installation can have up to four different packages: vShield Zones, vShield Edge, vShield App, and vShield Endpoint. A fifth package, vShield Manager, manages the services of each.
