Overview
Paubox
Paubox solves the complexity of HIPAA compliant communication by encrypting your emails automatically in the background. Unlike traditional secure email portals that require passwords or extra logins, you can compose and send messages from your familiar inbox on any device. This approach ensures your protected health information stays secure while maintaining a smooth experience for both your staff and your patients.
You can integrate the solution with Google Workspace, Microsoft 365, or Microsoft Exchange to achieve seamless encryption for every outbound message. Beyond basic encryption, the platform provides advanced threat protection to defend your organization against phishing, malware, and executive spoofing. It is designed specifically for healthcare providers who need to balance strict regulatory compliance with daily operational efficiency.
Zix
Zix, now part of OpenText, offers a unified platform to secure your business communications and protect sensitive information. You can automatically encrypt outbound emails based on predefined policies, ensuring that financial data, healthcare records, and personal identifiers never leave your network unprotected. The platform integrates directly with Microsoft 365 and Google Workspace, allowing you to maintain a familiar workflow while adding enterprise-grade security layers against phishing, malware, and ransomware attacks.
You can also simplify regulatory compliance with automated archiving and eDiscovery tools that capture all communications in a searchable, tamper-proof environment. Whether you are navigating HIPAA, GLBA, or GDPR requirements, the software handles the heavy lifting of data retention and audit preparation. It is designed for organizations in highly regulated sectors like finance, healthcare, and government that need to balance open collaboration with strict data privacy standards.
