AT&T Announces New Managed Services Contract with American Nuclear Insurers

Glastonbury, Connecticut, July 31, 2008

AT&T Inc. (NYSE:T) today announced a data services contract with American Nuclear Insurers (ANI), a joint underwriting association that provides liability insurance for nuclear facilities throughout the United States. Under the terms of the contract, AT&T will serve as ANI's primary data services provider, delivering AT&T Secure E-mail Gateway service and AT&T Web Security to the company's headquarters.

AT&T Secure E-mail Gateway service will provide ANI with network-based e-mail security and message management. The service will help ensure the integrity of e-mail messages before entering the ANI network by providing a first line of defense that safely builds a bridge between the Internet and the network. ANI will also use the solution's E-mail Continuity feature, which will support an online e-mail database for the company's e-mail correspondence. With E-mail Continuity, the service maintains a copy of e-mail and attachments separate from the production environment. Should ANI's mail server or Internet connection fail, ANI employees can immediately switch to a Web-based e-mail client provided by AT&T. When normal service is restored, AT&T will synchronize with ANI's mail server.

"Due to the nature of our business, it is critical that we have e-mail and network security measures in place, ensuring secure employee-customer communications and data backup," said Daniel Antion, vice president, American Nuclear Insurers. "By implementing security services provided by AT&T, we are confident that our network will be protected from viruses or other service interruptions, resulting in better productivity and enhanced customer service."

With the increasing demands of mobile users, ANI needed a solution that would support secure communications between employees and customers, as well as an effective system for data backup. Additionally, ANI will use AT&T Web Security to monitor and help prevent Internet attacks in the form of viruses and spyware, which could migrate from users' PCs to the company network. The service is maintained by AT&T, providing ANI with the reassurance that AT&T will provide protection for the company from viruses and spyware before they can even hit the network.
