eperi Cloud Data Protection for Microsoft 365

As more and more companies are pursuing a cloud-first strategy, users are accessing cloud applications like Microsoft 365 (former Office 365) anytime and from every type of device. However, regulatory requirements and company-internal compliance rules stipulate that personal and sensitive data should never be shared with unauthorized third parties. That’s where the eperi Gateway comes in. It enables companies to protect access to cloud-based data using cutting-edge security standards. And the most important thing: your end users won’t notice any difference and can use key Microsoft Office 365 functionalities in the cloud with no restrictions.

The eperi solution ensures that all sensitive information is encrypted before it is transferred to the Microsoft 365 cloud. Only authorized employees of your company can access the unencrypted data. Even administrators and employees of external datacenters can’t view the information in plain text format.

The eperi Gateway provides an ideal complement to the security and data protection features in Microsoft 365. The encryption process only takes place within your company, so your data is useless to unauthorized people once it’s stored in the cloud. That means you can protect your data while simultaneously fulfilling internal and external compliance requirements

The eperi Gateway:
Protects your Data before it leaves the control of your company

With the eperi Gateway, your company stays in control of your data – at any time. All sensitive data is encrypted before it leaves the company and is stored in the cloud. This is how the eperi Gateway prevents data from being misused.
