VMware vShield allows us to monitor scan and remediate virus and malware issues on our Virtual Machines. vShield works at the hypervisor level allowing a single anti-virus suite to be loaded and monitored per host rather than per VM. This has major resource savings in that only one copy of an anti-virus program has to be running per host. In addition to that malware cannot hope to disable or remove the anti-virus software since it cannot escape to the hypervisor level. This greatly increases the performance, security and manageability of a virtual environment. In our environment we have used Trend Micro and Kaspersky Anti-Virus, however we found Kaspersky’s deployment and reliability to be far superior than Trend Micro’s.
