How to Audit Who Has Accessed Your Shared Files

You shared a confidential proposal with three potential clients. One of them leaked it. Which one? Without an access audit, you have no way to know. Access auditing turns "someone saw the file" into a traceable chain of events.

What Access Auditing Records

A good file access audit log captures:

• Timestamp of each view or download
• IP address and approximate geolocation of the accessor
• Device type and browser (user agent)
• Whether the file was viewed or downloaded
• Which specific link was used (useful if you created separate links per recipient)

Strategy: One Link Per Recipient

The simplest audit strategy: generate a separate shareable link for each recipient. When you see access from an unexpected time zone or an anomalous IP, you immediately know which link — and therefore which recipient — was the source. This works even without email capture.

Email Capture for Identity Verification

Some file sharing platforms allow you to gate access behind an email entry form. Before the recipient can view the file, they must enter their email address. This adds both an identity check and an audit record. TiniDrop's Pro plan includes email capture functionality for exactly this use case.

Integrating Audit Logs into Your Security Stack

For enterprise environments, file access events should flow into your SIEM (Security Information and Event Management) system. Most enterprise file platforms offer webhook or API access to event logs. Set up alerts for suspicious patterns: file accessed from a foreign country, file downloaded more than 10 times in an hour, file accessed at 3am.
