Why Encrypted Email Is Important
Do you want to ensure that your email and its contents remain private? If so, then you should consider encrypting your email. On a larger scale, you may need enterprise-level email encryption to protect proprietary data or to meet and maintain government and industry regulated compliance mandates. Ultimately, the enterprise needs to encrypt their emails to protect their data in transit, while also protecting them from “man in the middle” attacks, which refers to data being intercepted before reaching its destination. Encryption is an effective technology to keep sensitive data secure and organizations compliant.
Features of Encrypted Email
Either by using encryption through your email service provider, a secure encrypted email solution, or through email security software, you can easily ensure that your email content remains protected.
Many secure email service providers offer an encryption component, such as OpenPGP. OpenPGP technology keeps data secure at rest, using a combination of strong public-key and symmetric cryptography to offer security services for electronic communications and data storage.
There are also web-based encrypted email services; however, that would mean relying on a third-party service provider to handle your sensitive data. For message encryption, most solutions include using Secure/Multipurpose Internet Mail Extensions (S/MIME) and OpenPGP. However, you’re required to install a security certificate on your computer and a public key, which is a string of characters that you would give your contacts prior to being able to receive an encrypted email. At the same time, the recipients of your email must follow the same protocols and not only install a security certificate but provide their public key ahead of time.
Most email clients like Microsoft Outlook allow users to send secure emails and support email encryption through S/MIME. There are also web browser-based email clients that support S/MIME, from Google to Firefox. Be sure to apply for a security certificate before you get started.
