Have you ever had the need to send private or sensitive information to someone? Perhaps driver’s license information, passwords, or financial information. We all have at some point and should know that basic email is not the best platform for that as email communication is not encrypted by default. Email communication can be secured, however, so that email is sent encrypted rather than clear text and your message contents can be protected.
As with any properly encrypted information transfer, the information needs to be secured both in transit, to protect against man-in-the-middle attacks, and at rest; meaning at the arrival destination, presumably a mail server or inbox somewhere. Major email providers like Microsoft and Google use TLS (Transport Layer Security) to provide the encryption in transit. This prevents the man-in-the-middle attacks where a hacker intercepts the message before delivery and is able to read the message contents.
The “encryption at rest” is the next step and an important one for security. Enterprise email encryption platforms, like the ones provided by Microsoft and Google, will provide the end-to-end encryption, meaning it ensures the encryption both during the transfer and at rest. These solutions have come a long way from the days of requiring encryption key setup at both the sender and receiver. Enterprise email encryption will often secure the message so that it cannot be forwarded to unintended recipients and even hide the message from email servers for further protection. This is an additional protection over solutions like sending an encrypted document over email which protects the document but not the message itself.
Most Enterprise email encryption platforms come with additional cost, although perhaps not as much as you might think. It is worth an inquiry as the usefulness of the additional security is well worth the expense in many cases.
