Email encryption is essential for companies that want to ensure the confidentiality of their communications. Email is not a secure method of communication and it is possible to expose its content to malicious people.
Therefore, it is necessary to encrypt sensitive emails and attachments.
Email encryption software allows organizations to secure emails, ensuring that they are only accessible to the intended recipient and providing end users with additional security controls.
So here’s an article that lists a selection of popular software to help you secure your emails.

That’s because the tool is provided in Outlook on Office 365 E3 and aims to help businesses protect sensitive emails, maintain control of their data and comply with their security needs.

Users who receive encrypted messages on other email clients can view them on the OME portal.
