Qwest Enhances Online Security for Businesses to Protect against Productivity and Intellectual Property Losses.

DENVER -- Qwest Communications International Inc. (NYSE: Q) today announced the enhancement of the Qwest suite of business class virtual private network, firewall and security services with new anti-virus/anti-spam (AVAS) solutions. Qwest AVAS gateway solutions now provide even more effective and essential e-mail protection and security services, safeguarding companies from receiving unsolicited e-mail, viruses, worms and unwanted content at the customers' external network perimeter.

According to the Yankee Group, security breaches of e-mail and other messages cost enterprises millions of dollars in downtime, productivity loss, intellectual property loss and system rebuilds. Almost 42 percent of respondents to the Yankee Group 2005 Security Leaders and Laggards Survey said they had experienced an e-mail security issue that disrupted more than one business unit. An additional 42 percent had also experienced disruptions that affected only one business unit.

Qwest AVAS uses award-winning technology to provide multiple layers of defense that are cost-effective, comprehensive and easy-to-use. The managed solution is customizable to suit individual business needs and offers an online customer management portal that lets customers control thresholds, reporting, filtering and account preferences.

The enhanced Qwest AVAS solutions - available nationwide - are geared toward small- and medium-sized businesses and government and education organizations, the majority of customers in the country. The services will provide tangible benefits when added to a variety of Qwest services, including Qwest iQ Networking[R] service, a converged networking platform, or Qwest OneFlex[R] Internet protocol voice products.

"Online security is one of the most important considerations customers should factor in to their network service choices," said Dan Yost, executive vice president for product and marketing at Qwest. "Qwest AVAS services provide the constant vigilance needed to ensure business continuity and network security."

With Qwest AVAS gateway solutions, customers make a simple change to their mail exchange record pointing it to a Qwest-specified network mail exchange record. All e-mail is then filtered through the Qwest anti-virus/anti-spam service before reaching the end-user. By providing this gateway, Qwest offers business customers the latest in spam protection and blocking, quarantine options and virus protection with 24-hour support.

The AVAS services are available to businesses nationwide via Qwest Business Markets Group. Qwest business markets group is responsible for the sales, marketing and delivery of voice, data and IP communications services to hundreds of thousands of Qwest's business customers, from small businesses to global enterprises.
