AT&T Inc. (NYSE:T) today announced that Seyfarth Shaw LLP, one of America's leading full-service law firms, has signed a multiyear networking services contract with AT&T.

Under the contract, AT&T will provide Virtual Private Network (VPN) services to support the firm's day-to-day operations and enable attorneys and office personnel to access critical corporate databases, proprietary applications and e-mail and collaborate in real time over a secure, high speed network.
