Enigmata Sentinel sends the full text being protected and original files added through supported attachment workflows to Enigmata's gateway over HTTPS. Files are processed when attached. Sentinel may also process draft-containing requests generated by supported provider pages before you press Send; the submitted Firefox build can send the complete matching request body to the gateway. The service returns protected content and values you are authorized to view. Sentinel also processes account/authentication data, conversation/session identifiers and security records. Full details about data use, recipients, storage, retention and your rights are in the Enigmata Privacy Policy.
