PreVeil Security is an end-to-end encrypted communication and file sharing platform built on a zero-trust architecture. Unlike traditional security models that encrypt data only in transit and at rest (decrypting on the server), PreVeil ensures data is never decrypted on the server—only intended recipients can access plaintext content. Key architectural components include: - **End-to-End Encryption:** Data is encrypted on the user's device and remains encrypted until decrypted by the recipient, eliminating server-side exposure even in the event of a breach. - **Cryptographic Identity:** User authentication is based on cryptographic keys rather than passwords, removing the attack surface associated with phishing, credential theft, and remote login attacks. - **Approval Groups:** Administrative trust is distributed cryptographically across a predefined group of administrators. No single admin can unilaterally compromise the enterprise. Admins can access decrypted corporate data for governance or compliance purposes only after receiving cryptographic authorization from approvers. PreVeil targets enterprise use cases and applies these principles to email and file sharing. The platform is designed to align with regulatory compliance frameworks including DFARS, ITAR, and CMMC, particularly for handling Controlled Unclassified Information (CUI). The security model is publicly documented in a whitepaper, adhering to transparency practices rather than security through obscurity.
