10 Best Practices for Secure File Sharing in 2025

1 min read

Sharing files is easy—but sharing them securely takes a bit more care. In this guide, we’ll walk through ten practical steps to keep your documents safe when sending them to clients, teammates, or anyone else.

1. Use expiring links

Links that automatically expire reduce the risk of long-term exposure. With Comfyfile, you can set a time limit so your files don’t linger online.

2. Add password protection

A unique password prevents casual snooping. Share the password over a different channel than the link.

3. Limit downloads

Restricting the total number of downloads helps you keep distribution under control.

4. Prefer HTTPS-only transfers

Always ensure transfers happen over HTTPS to prevent interception.

5. Avoid permanent storage when possible

Use temporary sharing for sensitive content. If it doesn’t need to live in cloud storage, don’t keep it there.

6. Share only what’s needed

Trim your archives. Remove unnecessary files and metadata before uploading.

7. Watermark or label sensitive docs

This creates accountability and discourages leaks.

8. Keep your devices patched

Out-of-date software is a common attack vector.

9. Verify recipients

Confirm emails or identities for sensitive transfers.

10. Audit your process

Periodically review what you share and where it’s stored.

Tip: Comfyfile supports passwords, expiries, and download limits—making these best practices effortless.
