How to Share Internal Documents Securely – Document Security Best Practices

Internal documents often include a company’s most sensitive information, from financial reports to proprietary research. Yet common sharing methods like email or USB drives leave these files vulnerable. In fact, studies show nearly 60% of organizations have been hit by attacks (like ransomware) when sharing data, and errors are frequent: one city employee once emailed confidential data for 3,700 coworkers to the wrong person. These incidents illustrate that without robust document security (encryption, strict access controls, etc.), a simple file share can trigger a major data breach.

Common Risks: Consider these scenarios across industries:

  • Education: A student or researcher might email a draft report or thesis to the wrong address. Once the attachment is sent, there’s no way to recall or protect it if it lands in the wrong hands.

  • Design/Creative: A designer emailing project blueprints to a partner risks the recipient forwarding those ideas. By the time the designer realizes, the concept could have leaked online, undermining competitiveness.

  • Finance/Banking: Sensitive customer data (IDs, financial records) sent insecurely can be intercepted or misused. Even after an employee leaves, any retained files can be exploited if not protected by rights management.

These examples show why “sending and forgetting” is dangerous. In fact, experts note that 55% of data breaches are caused by human error, underscoring why organizations can’t rely on unsafeguarded attachments. Every shared file must be treated as a potential risk.

Essential Document Security Practices

According to industry recommendations, strong encryption is a fundamental requirement for protecting sensitive information. To mitigate these risks, enterprises should apply multiple layers of protection around each document:

  • Encryption: Always encrypt files both in transit and at rest. Strong algorithms (e.g. AES-256) ensure that if a file is intercepted or stolen, it remains unreadable without the key.

  • Access Control: Require strict authentication for every file access. Use multi-factor authentication (MFA) or unique passwords so only intended recipients can open the document. Assign minimum necessary permissions (view-only, edit, etc.) based on user roles.

  • Post-Send Restrictions: Prevent actions like downloading, printing, copying, or screenshots after sharing. Modern Information Rights Management (IRM) systems let you send view-only links for Office/PDF files, overlay dynamic watermarks, and even revoke access remotely. This way you retain control over the document throughout its lifecycle.

  • Audit & Revocation: Keep detailed logs of all document activity (who accessed what, and when). Monitoring provides compliance evidence and alerts you to anomalies. Critically, choose a solution that allows you to stop or expire access at any time (for example if a leak is suspected).

By combining these practices, companies enforce true document security instead of relying on insecure “send-and-hope” methods.

689Cloud Document Security Solutions

To implement these safeguards without hampering productivity, 689Cloud offers integrated secure sharing tools. Our platform brings encryption and IRM directly into email and cloud workflows. For example, SecureDrive provides cloud storage with advanced IRM controls, and SecureMail secures email attachments with built-in encryption and rights management. This means employees can use familiar tools (email, OneDrive, etc.) while IT enforces enterprise-grade document policies.

Key 689Cloud features include:

  • SecureMail (Email Attachments): Converts any attachment into a secure web link that only specified recipients can open (protected by two-factor authentication). Microsoft Office files (Word, Excel, PowerPoint, PDF) can be sent in a non-downloadable view-only mode to reduce leaks. Dynamic watermarks with the recipient’s email and time stamp are applied to discourage screenshots.

  • Password-Protected Sharing: If a file must be downloaded (e.g. large video), 689Cloud wraps it in a ZIP file encrypted with a unique password for each recipient. The system sends the password automatically, so you never have to manually manage keys.

  • Digital Rights Management (DRM): In SecureMail’s Pro version, even downloaded documents remain protected. DRM blocks copying/pasting and can disable screen capture. Crucially, you can revoke access to the file even after it’s been downloaded, ensuring you stay in control.

  • Tracking & Audit: Every interaction with a protected file is logged. The SecureMail console shows exactly who has viewed or downloaded each file and when. Administrators can instantly revoke a recipient’s access to a shared file at any time, which provides a critical safety net.

  • SecureDrive: SecureDrive is a cloud file-sharing service built on IRM. It integrates seamlessly with your workflow (familiar file-explorer interface, shared folders, team roles) but adds enterprise security. All file access requires 2FA and is tracked. Managers can set document expiration dates and disable printing (even “print to PDF”). Online documents remain encrypted in the browser, and every view is watermarked with the user’s identity and timestamp. Users only see what they’re allowed (view-only or edit), and IT can revoke or expire access at any moment689cloud.com.

By using 689Cloud, organizations gain all the elements of document security – encryption, strict authentication, IRM controls, and visibility – packaged into easy-to-deploy solutions. Employees can share large files and sensitive documents without change in their workflow, while you enforce protection on every file.
