How we protect your files
Every file you share through Hirosend is automatically encrypted. No setup. No configuration. Just secure file sharing.
We use military-grade encryption — the same standard trusted by governments and financial institutions worldwide.
When you upload a file, it's protected during transmission using secure HTTPS connections. From your device to our servers, your files are encrypted every step of the way.
Once your file arrives, we encrypt it before storing it on our servers. Each file gets its own unique encryption key. Even we can't see what's inside your files.
After encryption is complete, the original unencrypted file is permanently deleted from our servers.
When someone downloads your file, it's transmitted over a secure encrypted connection. The file is decrypted only when it reaches the recipient's device.
Beyond encryption, you can add extra layers of security:
