FAQs, answered

Encrypted email?

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 solutions to make sure email contents can't be read by anyone other than the intended recipient.

Is email not secure?

Email has been around as long as the internet has and it was never designed to be secure.

When you send an email, it travels through multiple nodes in a network. At any one of these, a threat 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, on the way to their receipt by your recipients.

Can I encrypt emails?

The most common email clients including Outlook, Gmail, and iOS provide a level of basic outbound encryption.

However, none of these offer recipients using any device an easy way to encrypt their replies.

Mailock also gives you the additional flexibility of multiple authentication options to ensure only the right people can gain access if a recipient's inbox is compromised.

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, an email encryption solution with authentication capabilities is the answer.
