Zimbra is the leader in open source, next-generation collaboration and messaging software.

We provide innovative experiences to end-users and their administrators because we see existing tools
are fundamentally broken. We also believe in compatibility with existing infrastructure and applications
(both open source and proprietary). Thus our solutions are cross-platform: including Linux and Mac OS X
on the server-side; Windows, Linux and Mac on the desktop; and Firefox, Safari and Internet Explorer browsers.

Key customers we work with include service providers, higher education institutions, and Fortune 1000
enterprises, particularly in the financial services, retail, and manufacturing sectors.
