  • The Leader in Cloud Email

    Crenza email hosting is the leading open source email solution with over tens of millions of mailboxes and counting. Our hosting offers over 200 new features focused on creating even better enterprise productivity, scheduling and file management, and improved manageability.

  • Avoid Lost Email

    Our hosting is implemented with real-time continuous data replication between two data centers, using high-reliability SANs and separate backups. In other words, realtime data replication for maximum availability is a standard feature. Also included is our own exceptionally accurate SpamStopsHere antispam and 30 day “email continuity” which helps protect you and your staff against accidentally deleted emails. Full archiving is an option, as is email hosting.

  • Secure Encryption

    Our Hosting Farm features 256-bit “banking grade” encryption , as well as encrypted server-to-server communications. We can help you deploy S/MIME or integrate crenza with your own (or our) third-party encryption/DLP solution as needed. At-rest encryption is also available.

  • Organised

    With Zimbra Calendar you can create calendar invites, track responses & manage resources such as projectors and meeting rooms all from within the email client. Received an email with details of an event? Within a few simple clicks you can create a calendar appointment, invite attendees and event schedule an online WebEx session.
