HIPAA-Compliant Secure Fax
Business-grade fax engineered for regulated workflows — encrypted transport, audit logging, retention controls and process-of-record handling — fitting healthcare, financial-services, legal and government operating models whose fax posture must produce defensible compliance evidence under HIPAA, PCI, SOX and similar scope.
Fax-to-Email & Email-to-Fax

Fax API & System Integration
Fax APIs for application-driven send and receive — fitting operating models whose fax traffic must be triggered from EHRs, ERPs, document-management systems, claims platforms or custom workflow tooling rather than initiated manually by end users.
