Two brothers took a security idea from the intelligence world and put it inside everyday email. Their wager: a file should carry its own rules, wherever it travels.
The file was never the whole problem. Progress ShareFile built a business around everything that happens before a document arrives, and after somebody clicks send.

After 20 years as a financial-institution CFO, Ron Daly found his second act in an unglamorous corner of fintech: the sensitive document nobody should send by email.
Banks, airlines and retailers still run on files - lots of them, moving at strange hours between systems that were never meant to cooperate. Files.com has built a profitable business by turning that unglamorous mess into visible, automated infrastructure.
Nick Stamos spent two decades stopping data from leaking. His answer to the messiest problem in enterprise IT - sharing files with outsiders - is to make sure the file never actually goes anywhere.
PreVeil is a Boston-based cybersecurity company, born out of research at MIT, that delivers end-to-end encrypted email and file sharing built on zero trust principles. Its data is never decrypted on any server, so it stays protected even if passwords are stolen, admin accounts are hijacked, or servers are breached. PreVeil has become the go-to compliance platform for defense contractors and other regulated industries needing to meet CMMC, NIST 800-171, ITAR, and DFARS requirements at a fraction of the cost of legacy alternatives.
