About Paubox
What is Paubox?
Paubox is a HIPAA compliant email solution built specifically for healthcare organizations. It automatically encrypts every outbound email sent through Google Workspace or Microsoft 365, eliminating the need for portals, passwords, or plugins on the recipient's side. Emails are delivered directly to the inbox while maintaining full regulatory compliance.
How does it work?
Paubox combines automatic encryption with AI-driven inbound email security. Its generative AI analyzes message tone, sender behavior, and intent to detect advanced phishing, ransomware, and spoofing attacks before they reach the inbox. When a threat is flagged, administrators receive transparent, human-readable insights explaining why the email was blocked.
Who is it for?
Paubox is designed for healthcare providers, hospitals, clinics, and any organization that handles protected health information (PHI). It is ideal for teams that need HIPAA compliance without disrupting their existing workflow. It is not intended for non-regulated industries or organizations without email compliance requirements.
Real use cases
Typical applications include sending secure patient communications, coordinating care between providers, delivering appointment reminders, and protecting against business email compromise. Paubox also offers an Email API for healthcare app developers sending transactional messages, and a separate Marketing solution for HIPAA compliant email campaigns.
