Untangle surpasses 1 million protected users mark

San Mateo, CA – June 4, 2009 – Untangle, Inc. today announced that it has over one million users now
protected by its network gateway applications.

“This is a great milestone for the company, and our customers,” said Bob Walters, Untangle, Inc.’s CEO. “Despite a tough market, our customer and community base has
continued to expand. Our core value proposition of a free, open-source-based network gateway, supplemented with premium applications and services, seems to be just right in this economic climate.”

Having been a pioneer in open source network gateway platforms, Untangle launched the Untangle Gateway Platform in June 2007 – the world’s first commercial-grade open source solution for blocking spam, spyware, viruses, adware and undesirable content on the network. In under two years the company has seen its user base grow from 9,000 in early 2007, to over 1 million.
