PreVeil vs Proton Mail

PreVeil provides end-to-end encrypted email and file sharing for defense and regulated industries. PreVeil Drive stores and shares encrypted files, with controls for viewing, editing, and commenting. Email works with Outlook, Gmail, Apple Mail, browsers, and mobile devices; Drive integrates with Windows File Explorer and Mac Finder, and is also available in a browser and iOS and Android apps. PreVeil says data is encrypted on users’ devices and only recipients can decrypt it. It replaces passwords with cryptographic keys and uses Approval Groups to distribute administrative trust among multiple approvers. The company says its platform is designed to support CMMC, NIST SP 800-171, ITAR, DFARS, HIPAA, the FTC Safeguards Rule, and CJIS requirements. Data subject to DFARS, CMMC, or ITAR is stored in AWS GovCloud in the U.S.; other data is stored in AWS Commercial Cloud. A free Basic plan includes 5 GB of encrypted storage. Paid plans include Individual at $25 a month, requiring annual payments, and Business at $30 a month per user, with monthly billing available.

Proton Mail is an encrypted email service available on the web, Windows, macOS, Linux, iOS, and Android. Its free plan lists 1 GB of storage and one email address, although its FAQ says storage starts at 500 MB; the free tier is described as having the same security level as paid plans. The service uses end-to-end and zero-access encryption, with open-source apps and independent audits. It blocks email trackers and includes phishing and spam protection, password-protected messages, and link confirmation. Users can schedule, undo, or snooze emails and organize messages with folders, labels, and categories. Easy Switch imports email, calendars, and contacts from other providers. Paid plans support external email clients through IMAP and SMTP using Proton Mail Bridge. Mail Plus lists 15 GB of storage, 10 extra email addresses, and one custom domain. Paid subscriptions include a 30-day money-back guarantee, and the desktop app has a 14-day free trial. Paid plans display monthly billing; the listed starting price is 3.99 /user/mo.
