What is email encryption?

Email encryption is the encrypting, or disguising, of email content to protect it from being intercepted. It is a key piece of outbound email security. Encryption is often coupled with identity authentication in secure email software to make sure email contents can't be read by anyone other than the intended recipient.

Why is email not secure?

Email has been around as long as the internet has and it was never designed to be highly secure. When you send an email, just like with any other data on the internet, it travels through multiple nodes in a network. At any one of these points, a bad actor could be present. It could be at your mail server, the server of your recipient, or somewhere in the middle. If your email contents are not encrypted, they can be accessed, even manipulated, before reaching their destination.

Can I encrypt emails?

The most common email clients including Outlook, Gmail, and iOS provide a level of basic encryption on delivery. They all offer optional S/MIME encryption as standard, and a Microsoft 365 E3 licence gives users additional functionality in the form of 365 Message Encryption. The key difference between the S/MIME encryption standard and the encryption available with 365 Message Encryption is compatibility. Whereas the encryption offered as standard by providers requires the recipient's email client to be S/MIME compatible, 365 Message Encryption keeps emails secure when delivered to recipients using any email provider.

It's important to ensure the level of encryption that you use suits your business' and your customers' needs. One key element in this is the level to which you will need to exchange sensitive documents. Are you're sending documents to be filled in and returned? The optional encryption offered by most email clients (S/MIME) protects documents in transit on delivery. They will only be encrypted on the way from you to your recipient. On the way back, they'll be open to interception. Equally, if someone can gain access to your recipients' inbox, they will be able to download and access any sensitive attachments. 

What is secure email?

A layer of encryption is important, but it doesn't protect against the #1 cause of data leaks - human error. If you send a sensitive email to the wrong person, encryption won't protect you. Secure email solutions combine identity authentication with email encryption, so even if you send an email to the wrong address, the wrong person can't gain access. Authentication methods can include device checks, challenge questions, or third-party certificates. If sending sensitive data to the wrong person is a concern, choosing an email encryption solution with authentication capabilities is the answer.

What is Mailock?

Mailock is a secure email solution that enables the safe and compliant exchange of confidential data. It combines award-winning encryption technology with multi-factor identity authentication to protect confidential emails from cyber risk and keep customer information protected.
