For your familiar environment:
REDDCRYPT Outlook plugin

With the REDDCRYPT Outlook you can encrypt and decrypt emails at the click of a button without having to leave your mail client.

The REDDCRYPT Outlook plugin combines security and easy usability. When clicking ‘Send’ in Microsoft Outlook you will be asked whether you would like to encrypt the email. This ensures that users don’t forget encrypting their emails and send unencrypted emails by accident.

If desired this prompt can, of course, be deactivated and with a click on Encrypt you can decide on your own when an email should be encrypted and when not.

No need for Microsoft Outlook:
REDDCRYPT Windows app

If you intend on encrypting emails frequently but you are not using Microsoft Outlook, our REDDCRYPT Windows application has you covered.

This application for the Microsoft Windows OS looks and feels like a mail client and is just as easy to handle.

When receiving emails in the future, those emails have an attachment that contains the encrypted emails. With a simple double click the attachment can be opened with the Windows app and you will be able to read and reply.
