Circle Data

Circle extends Zero-Trust security to data 

With Circle, the same encryption keys used to authenticate identities can be used to secure data. Circle encrypts data at rest and in transit, enabling collaboration with encrypted data and providing visibility to only authorized users.


  • Control of data access rests entirely - and only - with the data owner
  • Zero visibility to data - or user metadata - for any outside parties
  • Zero keys and zero attack surface in the cloud
  • All with frictionless UX, easy implementation, and support

Extend Zero Trust to your most critical and important data with flexible controls and ease of use through integrations with popular applications like Microsoft SharePoint and Office365.

Deploy an invisible, frictionless UX for E2EE that users will love

Circle's paradigm-shifting architecture makes it built-in, invisible, and available on demand according to your policy engines' use case, user context, or data permission set.
