In the era of cloud computing and remote collaboration, businesses are exchanging data at lightning speed. Sales presentations, invoices, contracts, and sensitive client records—digital file sharing is a matter of daily life.
With speed and ease, you also lose security.
Every file shared is an opportunity for data theft, leakage, or unauthorized access. According to the IBM 2024 Cost of a Data Breach Report, a misconfiguration, human error, and insecure practices, including improper file sharing, are among the primary reasons for data breaches, many of which can be averted by proper access controls and file encryption.

Let’s think about this:
Are you still using plain email for document transmission?
Are you using Google Drive or Dropbox with open links?
Do your shared links expire? Are they password protected?
If no — you are vulnerable.
This blog is a complete guide to data leak prevention while sharing files, especially for modern companies. You’ll learn why there are leakages, how to prevent them, and why NFC Vault will be the most secure file-sharing platform for enterprises by 2025.
Understanding Data Leaks in File Sharing
A data leak is an event wherein sensitive information gets exposed either deliberately or accidentally to unauthorized persons. There can be leaks at many levels when it comes to file sharing:
- Unencrypted Files: Shared through email or third-party applications
- Open Access Links: Anybody having the link can access/download the files
- Weak or No Authentication: Allowing interested intruders to easily log in
- Re-sharing Without Consent: Cares less if the recipient forwards documents
- Loss of Visibility: No visibility of who opened the file or when
Real-World Instances of File-Sharing Mishaps
- Healthcare Firm Fine – $2.2 Million An employee mistakenly sent patient records to the wrong recipient by way of email. The data was neither encrypted nor password-protected.
- Tech Startup Data Breach Product documents were shared on Google Drive with Public accessibility. The competitors downloaded confidential R&D files.
- Law-Firm Violates GDPR Nonexistent access controls and expired credentials theoretically allowed unauthorized users to gain access to a client’s contract — thus failing to be compliant.
These examples aren’t rare. Such incidences occur daily—and loss extends beyond mere money. Businesses lose trust, reputation, and undergo legal scrutiny.
Best Practices to Prevent Data Leakage While Sharing Files
Your ultimate checklist includes the following:
- Use Encrypted File Sharing Tools
Always select a platform offering end-to-end encryption (E2EE). This means that even if someone intercepts the file, it is impossible to read its contents.
- NFC Vault encrypts files upon uploading, transit, and storage.
- Maintain Role-Based Access Control (RBAC)
Users with certain roles should be able to access files. Limit what they can do to viewing, downloading, editing, or sharing.
- NFC Vault allows you to curate user roles, along with document-level access permissions.
- Set Expiry Dates to Shared Links
Never keep active links for a very long time; always time-limit your URLs to self-expiry.
- NFC Vault allows you to set expiry dates with a few clicks.
- Set Passwords on Files
An additional layer of defense for file links is a strong password in case of a leak.
- NFC Vault can be used to password-protect a document.
- Track Files in Real Time
Find out who accessed the file, when, from where, and what they did in the file.
- NFC Vault offers audit trails, activity logs, and real-time alerts.
- Block Downloading, Printing & Forwarding of Files
Allow “View only” view mode for highly sensitive documents so no download or screen capture can take place.
- NFC Vault affords watermarking and print restrictions for confidential documents.
- Integrate With DLP
Stop the accidental sharing of PII, financial records, or intellectual property.
- NFC Vault can act alongside enterprise-grade DLP solutions.
- Use MFA (Multi-Factor Authentication)
A password and, perhaps, a simple challenge question are not enough; there has to be some kind of second layer of login protection.
- NFC Vault provides built-in MFA for both admin and user accounts.
- Restrict Re-sharing & Limit Device Access
Block document forwarding and allow document access only from certain IP addresses or devices.
- NFC Vault supports IP restriction along with device tracking and geo-fencing.
- Review File Access Regularly
Review periodically to see what has been given to whom. Remove any with expired/unused permissions.
Pro Tip: Avoid Free Tools for Business File Sharing
