Solution for business

Secure email service that can be deployed for any company and organization

What problems are solved with protected email service

Check Minimizing the risk of leakage when information is shared with external recipients who can use received messages for other than the purpose specified, and transfer it to third parties (intentionally or accidentally).

Check Tracking documents that have left the perimeter of company's information system. Standard DLP-systems do not allow you to track messages that were sent to external recipients.

Deployment

The solution is deployed on the client’s side. Thanks to integration with the corporate email server, a standard email client gets a new feature - to provide protection for email messages and attachments. The protected emails are sent from a usual sender’s email address without any changes.
