Though it’s likely not at the top of your list of the IT security measures you need to implement, a Comodo email certificate is nevertheless vital to your organization’s security, health, success, and reputation.
This is because email communications are integral to the operations of many businesses, including yours. This instantaneous virtual communications channel connects employees with their colleagues worldwide as well as with their customers, vendors, and partners. It is fast, easy to use, and convenient. One thing it may not be, however, is secure.
Most email providers offer SSL/TLS encryption as a way to secure their customers’ communications. Well, great! They’re encrypting my emails, so this must mean that my information is secure, right?
Wrong — and here’s why, along with what you need to know about how to use a Comodo email certificate to secure your email:
SSL/TLS encryption secures the connection between you and the mail server, and the mail server to the internet. It does not, however, encrypt the content or attachments of your email communications themselves. This is the difference between in-transit and at-rest data protection.
In-transit data encryption, much like it sounds, only protects your information when it is on the move or being transmitted from one location to the other. At-rest data encryption, on the other hand, encrypts the data before it is ever sent to the mail server. This means that your information, while it’s sitting in your inbox or in your email recipient’s inbox, is not secure. This is where a Comodo email certificate, or what’s also known as a Comodo authentication certificate, comes into play.
A Comodo email certificate is a type of email signing certificate that is put out by Sectigo (formerly known as Comodo CA). This type of certificate serves dual purposes: It allows you as an email sender to digitally sign and encrypt your emails. It does this through the use of the S/MIME protocol, or what is known as a secure/multipurpose internet mail extension. Protocols are a set of rules that allow computers to transmit information between electronic devices such as computers and networks.
A huge benefit of using an S/MIME certificate is that it provides non-repudiation of origin with regard to your emails. It proves the sender of an email through a timestamped digital signature. This means that your recipients will know that your emails came from you and that a cybercriminal is not spoofing you.
When you install an email certificate on your email client and enable it for digital signing, it applies the following steps for each email to create a unique digital signature. Here’s how the process works:
By encrypting your emails, you’re protecting the integrity of your email data (MIME data). Essentially, the use of the S/MIME protocol in email communications increases the privacy of your communications and overall data security. This is done using your recipient’s public key to encrypt the message to create at-rest data protection. Because S/MIME offers at-rest and in-transit data protection, you’re able to keep your emails secure until the intended recipient with the private key decrypts them.
Users who use email clients whose servers are encrypted with SSL/TLS and use S/MIME get the best of both worlds: They can encrypt both data in transit and at rest for more fully protect the integrity of your data.
