Overview
Proton Drive
Proton Drive gives you a highly secure space to store, share, and sync your most sensitive files. Unlike traditional storage providers, it uses end-to-end encryption, meaning not even Proton can see what you upload. You can access your data from any device while knowing your privacy is protected by Swiss law and open-source, audited code.
You can easily organize your digital life with folders, automatic photo backups, and secure file sharing links. It is built for anyone who prioritizes privacy, from individuals protecting personal photos to businesses securing confidential documents. You get a seamless experience that integrates with the broader Proton ecosystem, including Mail and Calendar, to keep your entire digital footprint private.
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.
