Digicert S/MIME Class 2 is an easy, affordable, and excellent solution to secure business email communications.

This SSL Certificate digitally signs and encrypts email messages using the S/MIME protocol, which verifies the sender and prevents tampering, allows access to specific applications, websites, or interfaces, as well as devices like laptops and cellphones, and provides enhanced security measures in case usernames and passwords are misplaced or stolen.

Digicert S/MIME Class 2 is used for two-factor authentication. Once a server is configured for client certificate authentication, it will only grant a user access to it if the client presents the correct client certificate. When using a web browser to connect to the server, without the correct client certificate, the client cannot even access the credentials page.

This email SSL Certificate is fully trusted by all major email clients, as well as internet browsers, ensuring you a safe business communication.

Here is a list of the most common questions our customers have when buying a DigiCert S/MIME SSL Certificate:

Open a ticket with us and let us know the following info:

A. Your Company Info:

What are Multi-Year SSL Subscription Plans?

Starting with August 19th, 2020, the maximum duration of publicly-trusted SSL/TLS certificates issued by all Certificate Authorities (CAs) has been set to a maximum of 13 months.

However, in order to make your SSL Management process time-saving and cost-effective, the CAs and SSL Dragon are offering you the 2 Year and 3 Year SSL Subscription Plans.

This means that you can still buy a 2 or 3 year SSL Certificate and continue to benefit from multi-year discounting, while still remaining compliant with the CAB Forum SSL requirements.

How the Multi-Year SSL works?

Due to security reasons, your SSL certificate is initially issued with a maximum 1-year validity.

Prior to the expiration of your certificate, SSL Dragon, on behalf of the CA, we will issue a free replacement certificate for an additional 1-year certificate, according to your Subscription Plan.

You will need to validate & install the replacement SSL:

a. If you have a Domain Validation SSL Certificate, a short verification of your domain name will be required via Email, HTTP, or DNS in order to issue the 1-yr replacement SSL.

b. If you have a Business or Extended SSL Certificate – an additional Business Validation/Extended Validation recheck and callback process will also be required.

You can still reissue your certificate at any time and as many times as you like during your Multi-Year SSL Subscription Plan.
