iChat Server Secure and affordable instant messaging for protected communications.

Mac OS X Server version 10.4 now includes iChat Server, a secure and affordable instant messaging service for organizations of all sizes. iChat Server eliminates the risk of traditional instant messaging services, which are not encrypted and can allow any message or file exchanged to be easily compromised. By deploying iChat Server within an organization’s firewall, users enjoy a secure communications environment and can exchange messages, files, voice, and video without the risk of third-party access. In addition to providing invaluable security, iChat Server makes this privacy both robust and affordable for companies with limited IT budgets. With no client access license fees, iChat Server easily scales as an organization expands. Additional users are simple to add and a single server can sustain the communication of up to several thousand users at no extra cost. During testing, iChat Server supported more than 200,000 user accounts sending over a million messages a day, with capacity to spare.
