Overview
PreVeil
PreVeil offers a simple way to add top-tier security to the tools you already use every day. By integrating directly with Outlook, Gmail, and Windows File Explorer, it adds a layer of end-to-end encryption that ensures only intended recipients can access your data. You don't have to worry about server breaches because your information stays encrypted from the moment it leaves your device until it reaches its destination.
You can easily manage compliance for regulations like CMMC, ITAR, and HIPAA using their specialized Drive and Email modules. It is designed specifically for defense contractors and regulated industries who need high-level security without the complexity of traditional encrypted systems. You can get started quickly with their free version for individuals or scale up to enterprise-grade management for your entire organization.
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.
