Freshpaint hashes all user identifiers and only sends data server-to-server so that PHI won't be shared with non-compliant destinations.
Freshpaint helps you manage what's considered PHI and where you can send it. Send the full customer data set to destinations where you have a BAA. Block PHI from non-HIPAA software.
Some vendors will sign BAAs then tell you not to send them PHI. Because Freshpaint is purpose-built to handle PHI and keep your tech stack HIPAA compliant, this is a BAA worth signing.
