PRESS RELEASE

DALLAS, Oct. 13, 2009 — AT&T* has announced the availability of Security Event and Threat Analysis and Security Device Management, two new managed security services available for businesses of all sizes.

These new services enable customers to engage AT&T security professionals selectively and simply to provide customized security support. Services range from security event analysis and threat management analysis to targeted security device management including firewalls, intrusion detection sensors and VPN servers.

The Security Event and Threat Analysis Service uses AT&T's expertise in security analysis to evaluate, correlate, and report on information from multiple devices and device types, both on the customer premises and embedded in the AT&T network. Features include:

* Prioritizing security events based on threat and risk management methodologies using AT&T and customer-defined standards * Rapid notification when security events are detected and identified as critical by the AT&T Security Network Operations Center * Event mitigation and security analyst counseling during critical security incidents * Global Security Operation Centers and 24X7 T1-T4 Analyst Coverage with portal access through AT&T's award-winning BusinessDirect' Portal.

With Security Device Management, AT&T provides complete, customizable monitoring and management of a business's security hardware and software, with a range of services including managing the customer's current security capabilities up to assessing, designing and implementing a custom security infrastructure.

"With Security Event and Threat Analysis and Security Device Management, customers maintain responsibility for the policy and ownership of security hardware, while tapping into our experience, resources and 'in the cloud' approach to cyber security," said Edward G. Amoroso, Senior Vice President and Chief Security Officer for AT&T. "Faced with shrinking budgets and complex, growing threats, businesses and federal government agencies are increasingly turning to AT&T to help safeguard and simplify their IT infrastructure as they prepare for an economic recovery."

In fact, 53% of U.S. IT executives indicated that investing in "business continuity and security solutions" could have the biggest positive impact on their business's growth as their company prepares for an economic turnaround, according to a recent study conducted by AT&T.1

These new services are a natural complement to AT&T's existing Security Consulting services, which include independent assessments of vulnerabilities inherent in customers' networks, as well as the policy and procedures surrounding them. Security Consulting services include Log Management, Security Policy Management, Vulnerability Analysis, Application Security, Trusted Advisor services and Payment Card Industry Solutions.

AT&T delivers a suite of security and business continuity services to help assess vulnerabilities, protect infrastructure, detect attacks, and respond to suspicious activities and events. More information on AT&T's managed security offerings can be found at www.att.com/security.
