No, we are not.
Gist does not natively support HIPAA compliant data transmission. We do not offer any encryption or security measures surrounding message transmission beyond those included in the SMTP RFC, which was not designed with HIPAA compliancy in mind.
We suggest you encrypt the message body of your emails on your end if you are concerned about being compliant with HIPAA or offer a secure download link for secure documents rather than transmitting them directly via email.
That being said, we do honor the regulations that the GDPR mandates. For more information about this, you can check out this article here: Gist and GDPR Compliance
