Problem
Healthcare organizations face significant challenges in securing protected health information (PHI) when communicating via email and text messaging, risking HIPAA non-compliance and potential data breaches. Traditional encryption methods can be cumbersome, requiring recipients to use separate, often unfamiliar, encrypted platforms, hindering efficient communication. This complexity can lead to workarounds that compromise security.
Solution
Paubox provides a suite of HIPAA-compliant communication tools, including email, marketing email, texting, and forms, designed for ease of use and seamless integration with existing platforms like Google Workspace and Microsoft 365. The platform automatically encrypts all outbound emails by default, eliminating the need for extra steps or recipient portals. Paubox's inbound security features offer advanced protection against phishing, ransomware, viruses, and display name spoofing, while its email API enables developers to send secure, transactional emails. Paubox helps healthcare organizations maintain HIPAA compliance while streamlining communication workflows.
