Business customers want a single network and platform to deliver voice, data, video and applications to their end-users. VPNs are quickly becoming the strategic platform to deliver on the goal of a networked enterprise -- anytime, anywhere, reliable, and highly secure networking. With AT&T's VPN portfolio, businesses can use a single infrastructure (their VPN network) to connect branch offices, headquarters, remote users, and third parties such as suppliers and customers.

Remote workers and road warriors have the same functionality as their co-workers in the company's headquarters or branch-based co-workers through the VPN network. They have seamless access to business functions, applications and intelligence, including customer service to order processing, procurement, and now, voice services, over a single network, including the same voice mail and the corporate dialing plans,

AT&T customers can access their VPN using virtually any access technology, such as mobile, Wi-Fi, DSL, dial-up and Ethernet.
