PreVeil is an end-to-end encrypted email and file sharing platform designed to protect sensitive data while meeting strict security and compliance standards. Built for defense contractors, government suppliers, and enterprises handling Controlled Unclassified Information (CUI), PreVeil offers secure communication that integrates with everyday tools like Outlook, Gmail, and file systems.
Unlike traditional email or cloud storage, which can expose data to breaches or unauthorized access, PreVeil uses modern encryption to ensure that only the sender and the recipient can access messages or files. Even PreVeil itself cannot read the data. The platform is specifically designed to help organizations comply with cybersecurity frameworks such as CMMC, ITAR, and NIST 800-171, making it a trusted solution for companies working with the U.S. Department of Defense.
PreVeil’s security model combines usability with military-grade protection, allowing users to communicate and collaborate securely without changing how they work.
Features
End-to-End Encrypted Email
PreVeil Email ensures that messages are encrypted on the sender’s device and can only be decrypted by the recipient, protecting data from interception or unauthorized access.
Secure File Sharing and Storage
PreVeil Drive provides a secure alternative to services like Dropbox or Google Drive, allowing users to store and share sensitive files with complete control over access.
CMMC & NIST 800-171 Compliance
Helps organizations achieve and maintain compliance with defense-related cybersecurity frameworks through built-in controls and audit capabilities.
Zero Trust Architecture
PreVeil operates under a zero-trust model, verifying every user and device before granting access and encrypting data at rest, in transit, and in use.
Granular Access Control
Admins can control who accesses what files, set permissions, revoke access instantly, and monitor all activity for compliance.
Seamless Integration with Outlook and Gmail
Users can send and receive encrypted emails directly from their preferred email interface, preserving productivity while boosting security.
No Passwords to Steal
Uses cryptographic key pairs instead of passwords, significantly reducing phishing risk and account takeover attacks.
Offline Access and Synchronization
Files and messages are available offline with automatic sync when a secure connection is restored.
Tamper-Proof Audit Logs
Tracks file access, sharing, and modifications with immutable logs to support regulatory and compliance audits.
How It Works
PreVeil is installed as a lightweight application on a user’s device and integrates directly with email clients (like Outlook and Gmail) and file systems (Windows and Mac). When a user sends an email or shares a file, it is encrypted locally using the recipient’s public key. Only the intended recipient’s device, which holds the private key, can decrypt and access the data.
PreVeil’s email and file services are cloud-hosted, but because of end-to-end encryption, the platform itself cannot access the content of any messages or files. This prevents insider threats, data breaches, and compliance violations.
Users can add or remove collaborators, assign permissions, and control access to sensitive data from a secure dashboard. All communications are automatically logged, and administrators have complete visibility for compliance reporting and incident response.

Scalable for Any Size Business
Whether you’re a small defense subcontractor or a large prime contractor, PreVeil scales to meet growing needs.
Drawbacks
Focused on Compliance Use Cases
PreVeil is purpose-built for industries with high compliance requirements and may offer more than what general businesses need.
Limited Support for Non-Email Collaboration Tools
While it covers email and file sharing, it doesn’t directly secure communication in tools like Slack, Teams, or Zoom.
Requires End-User Setup
Although setup is simple, users still need to install the application and manage encryption keys, which may involve some onboarding time.
Comparison with Other Tools
Compared to encrypted email providers like ProtonMail or Tutanota, PreVeil is built specifically for enterprise and defense use cases, offering deeper compliance alignment and integration with Outlook and Gmail.
While file-sharing services like Box Shield or Egnyte offer secure storage, PreVeil’s end-to-end encryption and compliance focus give it an edge for organizations handling CUI, ITAR, or DFARS data.
In contrast to legacy email security tools, which protect data in transit only, PreVeil ensures end-to-end encryption, providing stronger protection against interception or unauthorized access.
Customer Reviews and Testimonials
Users consistently highlight PreVeil’s strong encryption, simple deployment, and effectiveness in passing compliance audits. Many defense contractors report that PreVeil helped them achieve CMMC readiness faster than expected.
Customers appreciate how PreVeil integrates with tools they already use, especially for Outlook and Gmail. The ability to securely collaborate with external partners—without asking them to buy or install new systems—is also a frequent point of praise.
Support and onboarding assistance are also rated highly, particularly for small businesses that may not have dedicated IT security staff.
Conclusion
PreVeil offers a powerful yet easy-to-use platform for protecting sensitive communications and files through true end-to-end encryption. Built with compliance in mind, it helps organizations meet CMMC, ITAR, and NIST 800-171 standards without forcing major workflow changes.
Whether you’re a small defense contractor looking to secure CUI or a large enterprise aiming to prevent data leaks and phishing, PreVeil delivers the tools needed to communicate safely and stay compliant.
