Use DLP controls to ensure sensitive content is encrypted

HighSide ties into Microsoft's DLP controls to force the use of the HighSide encryption extension to send and share specific types of data. Don't trust your users to remember to do the right thing, make sure they can't forget.

Zero Trust means don't trust your users, admins, EKM keys, HighSide, and even Microsoft

  • HighSide provides an underlying key management infrastructure, linked with Microsoft user accounts, to seamlessly provide FIPS 140-2 grade encryption.
  • Eliminate risks with private key management and M365 admins have access to your keys.
  • Trust no one, especially Microsoft. HighSide doesn't own your encryption keys, the distributed nature of our encryption management layer ensures there is no single point of failure.

How it works

1

Your Teams administrator makes the HighSide extension available to the appropriate users. It is instantly deployed across all of their devices.

2

Next time users access Teams, they will see the HighSide extension in their message bar. When clicked, the HighSide extension opens a new message window.

3

Messages & files sent using the HighSide extension are automatically end-to-end encrypted, and can only be decrypted by your other team members whom you’ve explicitly given access.

4

To unauthorized users, including Microsoft employees, HighSide employees, users without the plugin and would-be attackers, messages sent with the HighSide extension will appear as an encrypted blob and will be undecipherable.
