need a big in-house Zimbra installation?

We have helped a number of companies (such as The Whitehead Institute for Biomedical Research at MIT) plan and execute a migration from their existing in-house email system to an in-house Zimbra system with near-zero downtime and minimum migration challenges.

  • Zimbra is incredibly cost-effective; typically around half the cost of a comparable Microsoft Exchange deployment.
  • Zimbra has more sharing features and end-user customizations than GMail.
  • Zimbra can authenticate natively against a number of backends, including Active Directory; Zimbra works very well in heterogeneous environments.
  • Zimbra has an open, well-documented API set and SDK that can be used for integrating Zimbra with a number of third-party applications like Salesforce.com, as well as with internal applications.
