Equinox Information Systems Named Top 50 Vendor By Service Provider Weekly Magazine

JOINS OTHER NOTABLE COMPANIES ON PRESTIGIOUS LIST

Nashville, TN — October 20, 2005 - Service Provider Weekly magazine announced earlier this week that Nashville-based Equinox Information Systems is included in their annual list of the top 50 service provider vendors.

"We received lots of nominations, tested them all out, asked countless questions, and generally turned them inside out” says the article. All the winners “are on this list because they really deserve to be."

"We are proud to be included in this list” said Byron Middendorf, CEO of Equinox Information Systems. "As we start our 20th year serving the telecom service provider market, it is a nice validation of our efforts to provide powerful products and custom solutions to our ever-growing customer base."

In the selection process, Service Provider Weekly recognized that Protector, Equinox’s telecom fraud management system, is the most the installed fraud management system in the US with installations at carriers including McLeodUSA, XO, Paetec, Primus, and NuVox. Protector has been on the market since 1988, and includes dynamic profiling, a flexible rules engine for customized monitoring, and powerful case management tool for collecting, arranging, and presenting data. According to the magazine, Equinox is the best vendor in the marketplace because the company has more experience (in terms of years on the market and number of customers) and offers the most compelling return on investment.
