7 Best Practices for Secure File Sharing in 2026
Sharing files online is essential for modern work, but doing it carelessly can expose sensitive data. Here are seven best practices to keep your files safe.
1. Use HTTPS-Only Services
Always share files through services that use HTTPS encryption. This ensures your data is encrypted in transit between your browser and the server. Look for the padlock icon in your browser's address bar.
FileDroppy uses HTTPS/TLS encryption for all data transfers.
2. Add Password Protection
For sensitive files, always add a password to your transfer. Share the password through a separate channel (text message, phone call) rather than in the same email as the download link.
3. Set Expiration Dates
Files that live forever on the internet are a liability. Use a service that automatically deletes files after a set period. FileDroppy's free plan expires files after 7 days, and Pro after 30 days — then they're permanently deleted.
4. Use Virus Scanning
Ensure the file sharing service scans uploads for malware. This protects both you and your recipients. FileDroppy automatically scans every uploaded file.
5. Avoid Public Links When Possible
If you're sharing sensitive documents, send the link directly to the recipient rather than posting it publicly. Anyone with the link can access the files (unless password-protected).
6. Use Unique Links Per Recipient
For maximum security, create separate transfers for each recipient. This lets you track who downloaded what and revoke access individually if needed.
7. Don't Use Personal Email for Business Files
Keep business files out of personal email accounts. Use a dedicated file sharing service with proper security controls rather than attaching sensitive documents to Gmail or Yahoo Mail.
Choosing a Secure File Sharing Service
Look for these security features:
- HTTPS encryption in transit
- Automatic virus/malware scanning
- Password protection for shared links
- Automatic file expiration and deletion
- CSRF protection and secure authentication
FileDroppy includes all of these features, even on the free plan.
