The most versatile SSL/TLS certificate available today is the multi-domain wildcard, or what’s known as a wildcard SAN certificate. Not only does it give you the flexibility to encrypt multiple domains — up to a total of 2,000 domains per certificate — but it can also secure any associated first-level sub-domains.
Paid vs Free Wildcard SSL — The Ultimate Comparison
Having an SSL certificate is a necessity for customers to feel secure on your site — especially if they’re inputting any data on the site. As more browsers follow Google’s lead in marking all HTTP sites as “not secure,” this is becoming an even more important issue. However, as more companies shift from HTTP to HTTPS, organizations like Let’s Encrypt have made access to free SSL certificates possible in a pursuit of making the web more secure for everyone. This includes free wildcard SSL certificates.

Cybercrime is at an all-time high and its onward march doesn’t seem like it will be stopping any time soon. According to the ThreatMetrix Q2 Cybercrime Report, cyber-attacks increased by 100% from 2015 to 2017, and they continue to do so even now. Google has led the fight against this escalation in Cybercrime by encouraging all websites to use SSL certificates to switch to HTTPS.

How to Install a Wildcard SSL Certificate on Multiple Servers
Installing a Wildcard SSL certificate on more than one server is easy with Comodo
A lot of people ask how to install a wildcard SSL certificate on multiple servers as a result of one bad policy by one big CA. We won’t name names or anything, but one large, overpriced CA (rhymes with shyshmantic) charges something called a server license, wherein you have to pay an additional fee for each server you install your SSL certificate on.
This practice is the embodiment of everything that’s wrong with the SSL industry. There is no good reason why you should have to pay an additional fee to use a product you’ve already purchased.
Can You Use A Comodo Wildcard SSL Certificate With Multiple IP Addresses?
Comodo allows its Wildcards to be used on unlimited servers
Many Certificate Authorities have strict policies when it comes to how many servers you may install their SSL certificates on. For instance, Symantec makes you pay a license for each server.
Comodo doesn’t believe in this, rather it wants to empower its customers to use its certificates on as many physical servers as they need. This means you can install one certificate on as many servers as you want or need without having to pay any additional fees.
By extension, this means you can use a Comodo Wildcard SSL certificate with multiple IP addresses on your system for all of your sub-domains.

How to Generate a CSR for a Wildcard SSL Certificate
Your guide to generating a Wildcard CSR on any server
Your Certificate Signing Request (CSR) is more or less an application for an SSL certificate. You can’t get an SSL certificate issued without one. A CSR is an encoded file that offers you a standardized way to send Comodo your public key and some information about your company or organization. Generating a CSR for a Wildcard SSL certificate is extremely similar to generating a CSR for any other SSL certificate, with one key difference: the asterisk.
Before you start
You’ll need to purchase a wildcard certificate before you start the install process. Comodo wildcard certificates start at less than $80/year. Save a bunch when you buy direct!

Filling out your CSR
Here’s the information you’ll need to fill out in your Certificate Signing Request for your Wildcard SSL CSR:
- Common Name (CN) – Your fully-qualified domain name goes here.
- Organization Name (O) – The legal name of your company or organization
- Organization Unit (OU) – What department or division of your company are you?
- Locality (L) – The city your company or organization resides in.
- State or Province (ST) – The state or province your company or organization resides in.
- Country (C) – The country your company or organization resides in.
- Email Address – Self-explanatory
- Root Length – Typically 2048-bit
- Signature Algorithm – SHA-2
What’s this about an asterisk?
Here’s the difference between a Wildcard CSR and a regular CSR, with the Wildcard you place an asterisk at the sub-domain level you’re attempting to encrypt (typically first-level) in your FQDN. For instance, if ComodoSSLstore.com was going to install a Wildcard, our input in the Fully-Qualified Domain Name field would be:
As long as you use the asterisk, your Wildcard will work correctly and encrypt your domain, plus all of its accompanying sub-domains. No limit. If you have one-million sub-domains, your Wildcard will cover all of them. And if you ever add another one during the Wildcard’s lifespan, just re-issue it and it’ll cover the new one, too.
