Enterprises need a full range of true enterprise clients and the freedom to use existing infrastructure. They need a robust, feature-rich, and open solution that lowers the total cost of ownership of messaging and collaboration.


If you work for a city, county, state, or federal agency you likely have a fixed budget and slim resources. You need a messaging solution that leverages your existing infrastructure and reduces your administrative overhead.


Education institutions need a messaging solution that effortlessly meets the needs of an ever-changing student population, that provides rich groupware functionality for faculty and staff, and that reduces the complexity and overhead of messaging.
