What is a virtual tap?

At this year's FOSE 2011 conference, Government Computer News (GCN) awarded Phantom Virtual Tap the Best of FOSE / Best Networking Product for Government award. The Tap delivers unprecedented total visibility into formerly murky traffic passing between VMs on hypervisor stacks. With its ability to tap traffic between virtual servers (VMs) on a physical server, the Phantom Virtual Tap heralds a new era of network compliance, management, and security for virtualized data centers.

Presented by Net Optics' Senior Solutions Engineer, David Pham, this webinar will briefly introduce you to the Phantom Virtual Tap as well as provide insight into some of the security and compliance challenges created by data center virtualiztion. Additionally:

Advantages of gaining visibility into your virtualized network infrastructure
How to eliminate visibility challenges in the virtual network
Provide attendees the opportunity to learn more about this new technology
