4 Best Practices for Sharing Files Securely
Files move constantly, often faster than anyone stops to think about how they’re moving. A single careless share can expose sensitive data to the wrong person or leave it sitting somewhere far less secure than intended. Here are four habits that keep file sharing safe without slowing anyone down.
- Share the Link, Not the File
Emailing an attachment means a permanent, uncontrolled copy now lives in someone’s inbox, which is forwardable, downloadable, and outside your reach. A shared link through an approved platform (like SharePoint, Google Drive, or OneDrive) keeps the file in one place, where access can be changed or revoked at any time.
- Set Permissions Before Sharing
“View only” and “can edit” aren’t just settings, they’re the difference between a document staying intact and someone accidentally overwriting it. Before sharing, ask who needs access and what they need to do with it. Default to the least access that gets the job done.
- Use Expiration Dates and Password Protection for Sensitive Files
Not every file needs to be shareable forever. Setting an expiration date on a link closes the window an old link can be found and exploited later.
For anything containing financial, legal, or personal data, add a password on top. Most Office files and PDFs let you set an “Open Password” directly (File → Info → Encrypt with Password in Word/Excel, or the security settings in a PDF tool), and a password-protected zip works for anything else. Just never send the password in the same email as the file. A quick text or separate message keeps the two apart if the email itself is intercepted. And where possible, a managed sharing link with an expiration date is still the stronger option; password-protected attachments are a good fallback when a link isn’t practical, not the default.
- Avoid Public or Personal Cloud Accounts for Work Files
Personal Dropbox, Google Drive, or USB drives feel convenient, but they sit outside company oversight entirely. There is no audit trail, no revocation, no visibility if something goes wrong. Work files belong in company-managed platforms, where IT can see and control what happens to them.
Secure file sharing isn’t about slowing people down with extra steps, it’s about making sure the right file reaches the right person, and only that person. A little intention before hitting “share” goes a long way toward keeping data where it belongs.
Frequently Asked Questions (FAQ)
What’s the difference between sharing a file and sharing a link?
Sharing a file sends a permanent copy that lives wherever the recipient saves it, with no way to control it afterward. Sharing a link keeps the file in one place, so access can be changed, revoked, or set to expire at any time.
How long should a file-sharing link stay active?
It depends on the purpose, but a common rule of thumb is 7–30 days for one-time shares and 90 days or less for ongoing collaboration. Recurring shares should be reviewed periodically rather than left open indefinitely.
What should I do if I send a file to the wrong person?
Revoke access to the link or recall the email immediately if your platform supports it, then notify your IT or security team right away. The sooner it’s reported, the smaller the window for the data to be viewed or downloaded.
