## Description

Circles of Trust™ is an enterprise application that provide file based protection. It enables the protection of high value data regardless of whether it is at rest or in motion. It is an easy to use security solution that allows end users to create a “trusted group” of people for simple and secure sharing. Encryption follows the data wherever it goes whether on an email, USB or sitting on someone’s desktop - only people in the Circle can access the file.
 
Circles of Trust™ is available as a managed enterprise version. It supports mobile devices and are compatible with all major cloud devices. Threat models that Circles of Trust™ addresses include: external hackers, lost or stolen devices, and accidental data exposure.

When sending an encrypted file from your mobile device, the user accepting the file will receive a COT file. COT stands for “Circles of Trust” and is the format used by Circles of Trust™ to denote that a file has been encrypted for a particular Circle.

When you have the Circles of Trust™ app installed on your mobile device, .cot files belonging to a Circle of which you are a member will appear with a Circles of Trust™ icon indicating that the file you are looking at is indeed encrypted. However, on your computer, .cot files belonging to a Circle of which you are a member will not appear as a .cot file, instead the file will have a Circles of Trust™ badge on the bottom corner to indicate that the file you are looking at is indeed encrypted.
