Today's businesses operate less on local/country or even regional levels, and more on a global level. With greater and more ubiquitous connectivity also comes greater opportunity for enterprises to discover the ways to connect and collaborate. The tools such as video telephony, web collaboration, e-communities, information sharing, and the like are growing in maturity and value. At the heart of these communications and collaboration models is the network, which serves as the primary conduit of business interactions and services among various sites, evolving at a greater speed. As the network evolves and grows, security technologies should evolve to transparently protect the data and various applications in the network.The Cisco VPN Services Port Adapter (VSPA) is the next-generation VPN module designed to support next-generation VPN technologies with system bandwidths of 8 Gbps in a modular, flexible, and scalable form factor.
