Active Cloud Backup

Security issue, hardware failure or cloud downtime? It doesn’t matter. You can switch to a backup system in a flash so that in no time at all you can be reached by email again and prevent commercial losses or damage to your company’s reputation.
Retarus’ Email Continuity provides transitional, ready-to-use, pre-provisioned webmail inboxes for all of your users. If an incident occurs, routing for your down email infrastructure can be redirected in an instant to the “active” backup. The webmail interface is user friendly and is essentially just like a typical email service your employees use for their private email. That means familiarization with the interface or training is not necessary.
The service is closely linked to Retarus Email Security, which means that Email Continuity is able to automatically provision and update webmail inboxes. And of course, these provisional inboxes are completely protected by Email Security. The Retarus Secure Email Platform can provide additional services in the failover solution, such as encryption or archiving, as needed, so you can continue working the way you usually do.

By the way, Retarus Email Continuity was intentionally not designed as a Microsoft-based product. This means you still get service even if these systems go down or are subject to targeted attacks.
