“Secure file” can refer to a few different things depending on your context—whether you are asking about protecting files on your devices, safely sending documents over the internet, or specific software libraries. 1. Secure Files in Cloud Storage & Sharing
If you are collaborating or sending documents, a secure file is protected with end-to-end encryption (meaning the data is scrambled on your device and can only be unscrambled by your intended recipient, so even the cloud provider cannot read it).
Security Features: Access controls (view, comment, edit), link expiration, password-protection for downloads, and multi-factor authentication (2FA).
Examples of Services: Proton Drive, Tresorit, and FileCloud. 2. Secure File Transfer (SFTP/MFT)
In IT and business, transferring a secure file involves moving sensitive data (like financial or healthcare records) through private, encrypted channels. These ensure that intercepted data remains unreadable and that data is not tampered with during transit.
Key Protocols: SFTP (Secure File Transfer Protocol), FTPS, and HTTPS.
Solutions: Managed File Transfer (MFT) platforms like GoAnywhere and Kiteworks. 3. Local Secure Files and Folders on Your Device
