- | One of the issues | + | One of the issues with increasing compliance regimes such as GDPR, CCPA, and increasing breaches of data is the issue of security. |
- | The secondary security concern can be with Cloud the Providers themselves. Users often want to protect certain files on the actual Cloud where they reside, and to that end they can want to use encryption | + | Most data services use an encryption 'at rest' data strategy. This encrypts all data that resides |
- | This particular use case can be solved by using the Cloud encryption service that SME provides. Encryption works when users upload files from SME web or desktop access clients, to any of the 40+ Cloud Storage and Saas Providers that SME supports. Users connect over SSL and assign files a private key phrase to file that are uploaded. | + | From a compliance perspective, |
