Sending an email is one of the most common forms of communication and a fast and reliable way of sharing information. Most people send or receive emails every day, but sending sensitive documents or information via email can be risky. This is especially true for industries like healthcare, finance, and law, where protecting sensitive information is essential.
If you are sharing secure or sensitive documents via email, you must be sure of the security of the email you are sending. If the sensitive contents of your email get into the wrong hands, you and your organization could face serious consequences.
For example, in healthcare, keeping patient records private is not just a legal requirement under The HIPAA Privacy Rule. In finance and law, if confidential agreements or sensitive case files are leaked, it can lead to financial losses and damage to reputations.
Is It Safe to Send Secure Documents Over Email?
There are many risks to using regular email for sensitive information. Documents could be intercepted during transmission or accessed by the wrong people. Regular email systems also lack security measures, so documents could be tampered with or changed without anyone's knowledge.
On the other hand, using secure email methods has many benefits. Encryption technology allows organizations to keep their sensitive information safe and ensure that only the right people can see it. Secure emailing also helps build trust with clients and partners, showing that a business takes protecting sensitive information seriously.
Do Government Agencies Use Email?
But can government agencies use email to send documents securely? Yes, they can, as long as they follow specific rules and regulations. For example, in the United States, government agencies must use encryption methods approved by the National Institute of Standards and Technology to keep sensitive information safe when sending it via email.
In the rest of this guide, we'll discuss the best ways to send secure documents via email. We'll also examine how popular email platforms like Outlook and Gmail can help and explain how encryption strengthens email security. By the end of this guide, you'll understand how to keep your sensitive information safe while using email.
Failure to comply with document requirements can have serious consequences. These can include legal fines, damage to your reputation, and disruption of your operations.

Sending Secure Documents in Email: General Practices
Cybercriminals increasingly target email as an avenue for data breaches, with business email compromise (BEC) attacks doubling in frequency in 2023. Therefore, it is important to understand how to securely send documents securely via email, particularly when dealing with sensitive information.
Encryption
Encryption is key to keeping email communication secure. Encryption jumbles up information into ciphertext, making it unreadable to anyone without the correct decryption key. End-to-end encryption is especially important for protecting email messages. Unlike other encryption methods that might leave information vulnerable at specific points, end-to-end encryption ensures that messages are encrypted from the sender's device and can only be unscrambled by the intended recipient. This level of security is crucial, especially when sending sensitive documents via email.
Integration of Encryption Software
Organizations can improve email security by using encryption software with their email services. This software provides advanced encryption to protect sensitive documents better when sent. By encrypting emails and attachments, organizations can reduce the risk of unauthorized access and interception by cybercriminals. Additionally, encryption software helps meet data protection and privacy regulations by adding an extra layer of security.
Password Protection
Using password protection for documents adds an extra layer of security when sending sensitive information via email. To limit access to authorized recipients, you can password-protect common file types like a PDF file, Microsoft Word documents, and ZIP files. It's essential to use a robust and unique password and share it securely to prevent unauthorized access.
Alternative Secure Methods
When sending sensitive information, there are more secure options than just using email encryption and passwords. File-sharing services, for example, provide safer ways to exchange documents by using encryption to keep data safe. These services also give features like access controls, expiration dates, and audit trails, which help organizations control who can access and distribute documents. By using file-sharing services in addition to email encryption, organizations can make it harder for data breaches and unauthorized access to happen.
How to Send Documents Securely in Outlook
Microsoft Outlook offers robust encryption features that allow users to send documents securely, protecting them from unauthorized access and interception. Let's explore how to utilize Outlook's encryption capabilities to send documents securely and third-party add-ons for enhanced document security.
Using Outlook's Encryption Features
S/MIME Encryption:
- S/MIME encryption converts email messages into scrambled cipher text, ensuring that only the intended recipient with the corresponding private key can decipher the content.
- Both the sender and recipient must have a mail application that supports the S/MIME standard. Fortunately, Outlook seamlessly integrates with S/MIME encryption.
- To enable S/MIME encryption in Outlook, users must first configure their signing certificate in the Trust Center settings.
Microsoft 365 Message Encryption (IRM)
- Microsoft 365 Message Encryption, also known as Information Rights Management (IRM), offers another layer of protection for email messages.
- With IRM, users can apply encryption and access restrictions to their emails, ensuring only authorized recipients can view the content.
- IRM protection should not be applied to signed or encrypted messages using S/MIME. Users must remove the S/MIME signature and encryption before applying IRM protection.
Encrypting with Third-Party Tools
- In addition to Outlook's built-in encryption features, users can explore third-party add-ons to enhance document security further.
- These add-ons offer advanced encryption capabilities and additional security features, providing users more options for protecting sensitive documents.
- Users should carefully evaluate third-party tools and ensure compatibility with their Outlook environment before implementation.
Encrypting Documents Directly in Outlook
Encrypting with S/MIME
- Before encrypting emails with S/MIME, users must add a certificate to their computer's keychain and configure it in Outlook's Trust Center settings.
- Once configured, users can easily encrypt emails by selecting the "Encrypt with S/MIME" option from the drop-down menu in the email composition window.
Encrypting with Microsoft 365 Message Encryption
- Microsoft 365 subscribers can use Message Encryption to apply encryption and access restrictions to their emails.
- Depending on their specific security requirements, users can choose from various encryption options, such as Encrypt-Only or Do Not Forward.
- Encryption options may vary depending on the user's subscription plan and Exchange Online usage.
