What Is a DigiCert S/MIME Class 1 Certificate?

Digicert S/MIME Class 1 is an easy, affordable, and excellent solution to secure email communications. This SSL Certificate digitally signs and encrypts email messages using the S/MIME protocol.

DigiCert S/MIME Class 1 Certificate Benefits

  • Email Encryption. DigiCert S/MIME Class 1 digitally signs your emails and enables end-to-end encryption between you and your recipients. By using a public/private key pair, your private key stays with you and is used to sign outgoing emails and decrypt incoming emails encrypted with your public key. Your public key is used to verify your signature and encrypt emails sent to you. Breaking the 256-bit encryption and a 2048-bit signature key is beyond human capabilities.
  • FDA ESG compliant. If you’re doing business with the FDA (Food and Drug Administration), encrypting your emails is a must. The ESG (Electronic Submission Gateways) verifies the senders’ identity before sending your email to the relevant FDA office. This email certificate ensures smooth and secure communication with the FDA.
  • Domain Control. This email certificate is quick and easy to obtain. All you have to do is prove you’re the owner of the domain you want to encrypt. The certificate info field will display your email address.
  • Compatible with almost any platform. This product will work on almost all servers, email clients, and browsers. You can install it on Windows, Linux, Mac, and many other platforms. It also supports major email servers such as Netscape Communicator, Microsoft Outlook, Microsoft Exchange, and Mozilla Thunderbird.
  • Protect Customers, Partners, and Your Brand. Email remains the most valuable tool for businesses of all sizes. Unfortunately, it’s also the easiest target for hackers. With millions of accounts compromised on a daily basis, now, more than ever it’s imperative to protect your business communications. DigiCert takes care of your email security and prevents data leaks and exposure, to leave you and your customers satisfied.

Great selection of certificates with a clear definition of properties for each certificate makes it easy to choose the right one.

Easier and cheaper than going directly and ordering via the vendor, thank you for the information and the simple shopping experience.

Excellent customer service when I ordered the wrong cert! The support team then helped me get the correct cert and refunded me on the incorrect cert I bought! Very fast and a happy customer.

June 23, 2020

One of the most reliable SSL brands. If you need to secure subdomains and can afford it, don’t think twice. Get it.

June 12, 2020

The price seems fair for an EV certificate, especially the two-year deal. Unlike my previous provider, which I won’t advertise here, at SSL Dragon, the buying steps are easier and better explained.

May 31, 2020

Always a pleasure doing business with SSL Dragon. Thawte certificates consistently deliver the highest encryption and customer trust.

May 16, 2020

Was assigned to secure several NGO sites. Picked this certificate because of a higher warranty and reasonable price. It’s always a pleasure to work with SSL Dragon.

December 17, 2019

Simply the best. Easy to buy and configure. Plenty of features. Can display the site seal in different languages as well.

November 5, 2019

A top-class product from a reputable company. Credits to SSL Dragon as well, for a smooth buying experience and excellent price.

May 3, 2019

This is the third SSL Certificate I buy from SSL Dragon, and the first one from GeoTrust. All I can say is the certs work as described in the specs, and the support is very friendly.

March 24, 2019

The SSL wizard recommended this certificate for our e-stores. We’re already on the third renewal, and during all these years, didn’t have a single issue with it.
