Circle Guard

Safeguard your data on endpoint devices and in Cloud

With Circle API, the same encryption keys used to authenticate identities and their actions can be used to secure data and communications end-to-end protecting data on the endpoint devices and in Cloud.

Finally, E2EE That Scales

Circle's unique, patented key management ditches the constraints of PKI to power End-to-End Encryption in applications without compromising scalability.

Exchange and store unlimited volumes of data securely and persistently for collaboration and communication within large groups and organizations.

Multicast encrypted communications to groups of ANY size with no additional overhead on the transmitting device or transport servers.

Patented, Out-of-Band Key Exchange

Circle's unique, patented peer-to-peer authentication eliminates the use of any central certificate authority, credentials or cloud-based identity databases, with all operations conducted within an AES-256 encrypted Circle.

Cloud Efficiency Without the Security Headaches

Encryption keys are created and encryption performed on endpoint devices — and NEVER in the Cloud. Circle thus eliminates the attack surface in the Cloud and raises the bar astronomically for bad actors to attack endpoint devices.

Large data files can be kept in the cloud, while keys stay on the endpoint device. Pull and use on demand just like any cloud application.

Data is Not Useable on Unauthorized Devices

Keys are bound to the endpoint device and cannot be taken off of the authorized device and used anywhere else. Enterprise data can thus be made useable and accessible only on devices that are authorized to have the keys.

Frictionless UX at the Highest Level of Security

With Circle, there is No Compromise between a great user experience and unrivaled privacy and security.

With credential-free and built-in continuous authentication, access to data and resources is frictionless. Users authenticate once and forget.

Secure emails, attachments, documents, files - any containerized data - seamlessly, in the background with no change to your user experience workflow.
