About Zimbra

Zimbra develops an email and collaboration suite that organisations can run on their own servers, in a private cloud or in regional data centres. Listed in the United States, it presents itself as an alternative to the large technology platforms for bodies that care about compliance and where their data is stored.

What Zimbra offers

  • Email and calendar — a secure mail and scheduling suite used through a web browser.
  • Flexible deployment — cloud, hybrid or on-premises installation to suit data residency rules.
  • Open standards — open source code that can be inspected and audited.
  • Collaboration apps — built-in tools plus links to third-party applications.
  • Local partner network — partners who deploy and support the software and help meet regional regulations.

Who it works with

Zimbra focuses on regulated sectors such as finance, government and education; it says more than 1,000 highly regulated institutions and over 6,000 organisations use the suite.

  • Based in: United States
  • Reach: 127 countries
