Secure File Transfer for Healthcare — SFTP and AS2 with Audit Logging

Healthcare organizations exchange files that require strict controls: clinical data, insurance claims, credentialing documents, lab results. These must be encrypted in transit and at rest, delivered reliably, and traced for compliance evidence.

PHI protection: files containing patient health information must be encrypted. Xferity integrates PGP encryption into the transfer flow so encryption is not a manual step that can be skipped.

AS2 for clearinghouse exchange: many healthcare clearinghouses and payers require AS2 with signed and encrypted messages and MDN receipts. Xferity supports AS2 with Postgres-backed message persistence for full MDN audit trails.

SFTP for provider-to-payer exchange: SFTP remains common for clinical data exchanges where a payer or lab provides an SFTP endpoint. Xferity enforces SSH host verification rather than accepting any server key.

Audit evidence for HIPAA: Xferity’s audit records document who transferred what file and when, with optional tamper-evident hash chaining. Records can be exported to external retention systems.

  • PGP encryption integrated into flows, not an external manual process
  • AS2 with signed, encrypted messages and MDN receipt records
  • SFTP with enforced host key verification
  • audit logging with file lifecycle records
  • security posture monitoring to detect when crypto configurations drift
