[Updated] Is it Safe to Transfer Files Via Email?

What are the risks of using email for file exchange?

Although it is convenient to send temporary files via e-mail, it, unfortunately, brings many security risks and deliverability issues, such as:

1. Lack of encryption

The email is sent in "clear text," which means unencrypted. Almost anyone who can view the traffic sent through the internal network or the Internet can access the attachment.

2. File size limit

Due to the size limitation of the provider or organization's server, it is usually impossible to send large files. And the sender often realizes that the file was not delivered correctly even before it's too late.

3. File type restrictions

Certain file types may not be allowed to protect against network attacks by viruses and spyware programs, which are usually hidden behind .zip, .exe, or .dat file types.

4. Lack of audit trail

When it comes to email, the method of providing the required compliance audit trail is difficult to implement or non-existent. To maintain compliance and avoid huge fines, many industries require detailed records of the whereabouts of information, the identity of visitors, and confirmation that sensitive data has reached its intended destination.

How can email be more secure?

Implementing a common encryption method can greatly improve the security of e-mail file transfer. Depending on your specific needs, you have many security options.

Why do you have a good sense of network security by automatically encrypting and decrypting?

Regardless of which protocol is used, data needs to be securely encrypted during transfer or transfer, as well as in a static state (such as storage on a server). Only when the users of the organization use this solution can you add more security to email file transfers. It is difficult to transfer files securely, and employees will only look for their own (usually insecure) solutions.
