Questions?

FAQs, answered

Encrypted email?

Email encryption is the process of encrypting, or disguising, 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 your recipients.

What is secure email?

A layer of encryption is important, but it doesn't protect against the #1 cause of data leaks - human error.

Secure email solutions combine identity authentication with email encryption, so even if you send to the wrong address, the wrong person can't gain access.

This also adds extra protection against threat actors, especially in the event of an inbox takeover attack.

Recipient authentication methods can include device checks, challenge questions, or third-party certificates.

Can I encrypt emails?

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

Mailock brings recipient authentication to email along with additional secure communications features that make it fit for businesses who need to transfer sensitive information, including:

  • military-grade encryption
  • trigger word warnings
  • free sends for recipients
  • high-volume delivery

What is Mailock?

It combines advanced encryption technology with multi-factor identity authentication to protect confidential emails from cyber risk and keep customer information protected.
