Tumbleweed and FaceTime Communications Form Alliance to Deliver Comprehensive Messaging Solution

Partnership Combines Tumbleweed’s E-mail Firewall with FaceTime’s Instant Messaging (IM) Security Solutions to Seamlessly Protect and Manage Multiple Channels of Online Corporate Communications

REDWOOD CITY, Calif., August 11, 2003 – Tumbleweed® Communications Corp. (NASDAQ:TMWD), a leading provider of mission-critical Internet communications software for businesses and government agencies, and FaceTime Communications, the premier provider of security and management solutions for instant messaging (IM) in the enterprise, today announced an alliance that enables customers to enforce and centrally manage corporate policies across both the e-mail and IM communication streams.

This partnership extends Tumbleweed’s e-mail firewall to capture and integrate IM traffic into a common management workflow, helping financial services and healthcare firms meet industry regulations and corporate policies, including SEC rules 17a-3 and 17a-4, NASD conduct rules 3110 and 3010, the Sarbanes-Oxley Act of 2002, the Health Insurance Portability and Accountability Act of 1996 (HIPAA), and FDA regulation 21 CRF Part 11 for surveillance, monitoring and archival. The combined solution has already been deployed and proven in the field by joint customers, including some of the world’s largest brokerage firms.

The National Association of Securities Dealers (NASD) recently recommended that brokerage firms supervise employees’ IM in order to ensure compliance with U.S. market regulations, as they do with e-mail and written correspondence. The NASD said companies should retain copies of all IM exchanges between brokers and customers for at least three years, bringing IM in line with other electronic communications guidelines.

The Tumbleweed e-mail firewall allows organizations to protect their networks, comply with e-mail regulations and policies, and securely communicate with customers, partners and suppliers. FaceTime’s enterprise IM management suite of security, management and control solutions provides customers with the added value of enforcing messaging policies traffic across the IM communication channel. This combination enables customers to capture, analyze and categorize message flow and then archive both e-mail and IM messages in a centralized repository, searchable through a common user interface.

“Many of the same concerns that drive enterprises to implement our comprehensive e-mail firewall, such as maximizing productivity, minimizing liability and ensuring compliance, also apply to Instant Messaging,” said Dave Jevans, Tumbleweed’s Senior Vice President of Marketing. “The fact that customers have already integrated our solution with FaceTime’s demonstrates the value of the combination.”

FaceTime’s enterprise IM management suite of security, management and control solutions help detect, control and administer the use of Instant Messaging and Internet chat, without requiring a change in existing client or server software. FaceTime’s solutions support all the leading public IM networks including AOL, Microsoft, and Yahoo!, as well as the leading private and enterprise IM networks such as IBM Lotus, Microsoft, Reuters and Communicator Inc.

“FaceTime’s partnership with Tumbleweed allows us to help our joint customers manage the risk associated with the variety of communication options available to employees,” said Christopher S. Dean, senior vice president of marketing and business development for FaceTime. “We are happy to work with Tumbleweed in offering a combined solution for the security, management and control of both e-mail and IM communications in the enterprise.”
