PreVeil is a cybersecurity company founded in 2015 and headquartered in Boston, Massachusetts, that provides end-to-end encrypted email and file-sharing solutions for businesses and individuals. The company's platform is built around three core principles: end-to-end encryption (where data is encrypted and decrypted on the user's device, never on the server), elimination of a central point of attack, and ease of use through integration with existing tools and applications. PreVeil's products are designed so that even PreVeil itself cannot access user data, as encryption keys remain on user devices. This architecture means that a server-side breach yields only unreadable ciphertext. The platform integrates with commonly used applications such as Microsoft Outlook and other existing workflows to minimize friction for end users. A significant portion of PreVeil's customer base consists of defense contractors and organizations that must comply with government cybersecurity frameworks. The company's solutions are used to help organizations meet compliance requirements such as CMMC (Cybersecurity Maturity Model Certification), which applies to contractors working with the U.S. Department of Defense. PreVeil's VP of Customer Success has firsthand experience achieving CMMC certification using the platform, which informs customer support for compliance journeys. The company is backed by investors including PSG and Spark Capital, and its board includes a retired U.S. Army Lieutenant General with extensive cyber command experience. PreVeil has been recognized as a Best Place to Work in Boston by BuiltIn for three consecutive years.
