# How to share confidential documents

Sharing confidential documents securely is a critical concern for businesses and individuals alike. With data breaches increasing by 70% in the past year and 82% of companies reporting unauthorized access to sensitive documents, choosing the right method for sharing confidential information has never been more important. Whether you're sharing legal contracts, financial statements, or intellectual property, this comprehensive guide will show you the best way to send confidential documents while maintaining security and control.

For organizations handling confidential client information, using a [secure document sharing platform](https://www.papermark.com/secure-file-sharing.md) is essential to maintaining trust and preventing potentially devastating data leaks.

## 4 methods for secure confidential document sharing compared

| Password-Protected PDFs | Moderate | Medium | None | Email transmission, basic security |
| Cloud Storage Security | Varies | Medium | Limited | Team collaboration, medium security |

Here are four effective methods for sending your confidential documents securely, from basic email encryption to advanced enterprise-level protection:

### Advanced security features for confidential documents:

| Security Feature | Description |
| --- | --- |
| Secure Data Rooms | Create dedicated spaces for all your confidential documents with controlled access |

| Expiration Settings | Set time-limited access to your confidential documents |

Papermark's security goes beyond simple password protection, offering comprehensive document security that maintains the integrity and confidentiality of your sensitive information.

## 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:

1. Sign up for a secure email service (ProtonMail, Tutanota, or Virtru)
2. Enable end-to-end encryption features in your email client
3. Draft a new email to your recipient
4. Attach your confidential documents directly to the encrypted email
5. Set an encryption password or PIN that only the recipient knows
6. Send the encrypted email through the secure service
7. Share the decryption password separately (via phone call or text message)
8. Request confirmation of receipt

### Additional email security measures:

| Security Measure | Description |
| --- | --- |
| S/MIME or PGP Encryption | For advanced users, implement email encryption protocols |
| Two-Factor Authentication | Secure your email account with 2FA to prevent unauthorized access |
| Encrypted Attachments | If your email service doesn't offer end-to-end encryption, use encrypted ZIP files |
| Verify Recipient Information | Double-check email addresses before sending sensitive documents |
| Set Expiration Dates | Use email services that allow messages to expire after a certain period |
| Limit Retention Period | Request that recipients delete the documents after processing |

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:

1. Scan or convert your confidential documents to PDF format
2. Open the PDF in Adobe Acrobat or similar software
3. Go to **File** > **Protect** > **Encrypt with Password**
4. Set a strong password (combination of letters, numbers, and special characters)
5. Configure permissions (restrict editing, printing, etc.)
6. Save the encrypted PDF
7. Share the password separately from the document

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:

1. Choose a secure cloud storage provider (Google Drive, Dropbox Business, Microsoft OneDrive, etc.)
2. Upload your confidential documents to the cloud platform
3. Configure sharing settings:
   - Set specific user permissions (read-only recommended)
   - Enable password protection if available
   - Set expiration dates for shared links
4. Enable two-factor authentication on your cloud account
5. 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.
