SuperFile is a secure file-sharing and identity platform that helps individuals, businesses, and institutions send files under a verifiable name. Its SuperFile service is designed to make file ownership clear and give senders control, with key-separated encryption and options to track and revoke shared files. Users can reserve a personal, business, or institution name in the SuperFile Registry; names are subject to verification, availability, and, for brand and institution registrations, human examination. Personal name reservations are free, while business names and optional custom file extensions may incur fees.

SuperFile also offers SuperSecure file encryption, a dashboard for managing names and files, and partner programs for organizations seeking company-wide deployment or distribution to customers. The company provides support through documentation, email, phone, and an AI assistant. It reports SOC 2 Type 1 and Type 2 attestations and ISO/IEC 27001:2022 certification, and says it operates in accordance with GDPR and HIPAA. SuperFile is in active development and offers early access through a waitlist.
