Method 2: Email encryption and password protection
Standard email is not secure for sending sensitive confidential information. However, with proper encryption and secure email services, you can add a basic layer of security:
How to send confidential documents via encrypted email:
Sign up for a secure email service (ProtonMail, Tutanota, or Virtru)
Enable end-to-end encryption features in your email client
Draft a new email to your recipient
Attach your confidential documents directly to the encrypted email
Set an encryption password or PIN that only the recipient knows
Send the encrypted email through the secure service
Share the decryption password separately (via phone call or text message)
Request confirmation of receipt
Additional email security measures:
While email encryption provides basic protection, it lacks comprehensive tracking capabilities and depends on recipients following proper security protocols. For professional document sharing or highly sensitive materials, consider more robust solutions.
Method 3: Password-protected PDFs and encrypted files
Converting confidential documents to password-protected PDFs provides a moderate level of security:
Scan or convert your confidential documents to PDF format
Open the PDF in Adobe Acrobat or similar software
Go to File > Protect > Encrypt with Password
Set a strong password (combination of letters, numbers, and special characters)
This method is relatively straightforward but lacks tracking capabilities and depends on the recipient maintaining proper security practices.
Method 4: Cloud storage security for confidential documents
Cloud storage services offer varying levels of security for your confidential documents, making them suitable for collaboration with trusted parties:
Choose a secure cloud storage provider (Google Drive, Dropbox Business, Microsoft OneDrive, etc.)
Upload your confidential documents to the cloud platform
Configure sharing settings:
Set specific user permissions (read-only recommended)
Enable password protection if available
Set expiration dates for shared links
Enable two-factor authentication on your cloud account
Regularly audit access logs to monitor who has viewed your documents
Benefits of cloud storage:
Automatic backup and version history
Controlled sharing with specific individuals
Access from multiple devices
Some file activity tracking
However, cloud storage typically offers limited tracking capabilities compared to specialized solutions like Papermark, and security features vary significantly among providers.
