Zivver Users

Empower secure work - in the office or at home

With Zivver you can safeguard your organization’s sensitive email data when using Microsoft 365 through more robust zero-keys, zero-access encryption, strong recipient authentication, advanced risk monitoring and data breach prevention tools.

Your data is your data

Unlike Microsoft 365 and many other cloud providers, Zivver cannot access data that is stored on its platform as it doesn’t have access to the user keys to decrypt the information.

Save time on training - we’ve got it covered

Our secure digital communications platform is intuitively designed to gently guide users in properly securing their communications before they hit send.
This includes ensuring that the correct security measures are applied, as well as providing safeguards to help users avoid the most common forms of data breaches.

Why spend more than you have to?

By combining Zivver with an Office 365 E1 or E3 license, you’ll have the added benefits of enhanced security and data protection, at a more cost effective rate than with an E5 license alone.

We’ve re-imagined secure communications from the ground up
