Email Encryption is a vital tool for businesses to ensure that their email communications are safe. Email is not a secure method of communication and it’s possible to expose the content of emails, putting confidential information and data at risk. Consequently, businesses need to encrypt sensitive emails and attachments.

Sending encrypted email is often compulsory for legal or regulatory reasons. It’s also often the case that a business has the information it wants to be kept out of public view. Email Encryption software allows businesses to secure emails, making sure they are accessed only by the intended recipient and giving end users more security controls.

In this list of the best email encryption solutions, we’ll be looking at the methods of encryption these products offer, the controls they provide to IT admins, their ease of use for senders and recipients and the quality of reporting they offer.
