In the domain name field of an SSL/TLS wildcard certificate, the wildcard character stands for any number of valid domain names. This means the certificate can protect many hosts with the same base domain. The client uses a shell expansion process to check the sub domain name in this certificate.
Benefits of Wildcard SSL certificates
When you have a lot of sub domains, each of them will need its SSL certificate. This will make managing SSL even more complicated. There’s no easy way to know when each cart will run out. You can protect as many sub domains as possible with a single SSL certificate wildcard. Rather than keeping track of several SSL certificates, keep track of one.
Reduce Management Cost
The SSL installation life cycle includes many steps, such as buying an SSL certificate, setting it up, verifying your identity, and installing it. Account teams handle purchases and spend more time and money on transactions involving many things. Setting up and installing wildcard certificate is done by the technical staff. One SSL process could take a skilled network administration up to 20 minutes. He would need about 200 minutes to install SSL separately on each of the ten sub-domains. Still, establishing a wildcard SSL certificate only takes 20 minutes, and SSL protects all ten sub-domains.
Cost if you want to use a different certificate to secure ten sub-domains, it will cost you at least $10 per sub-domain, or $100. Get a SSL wildcard certificate for $34.00 to save up to 58%. Also, setting up the same wildcard SSL on different hosting servers costs nothing extra. You can protect as many sub domains as possible with a single wildcard SSL certificate.
Your SSL wildcard certificate will run out at some point, and you’ll have to renew it before you can use it again. To renew an SSL wildcard certificate, you must go through the same steps as buying it for the first time. It takes more time and money to renew each SSL certificate separately. With a single SSL wildcard certificate renewal, all sub-domains can be kept safe. This is easier to manage and costs less money.
How to Use Wildcard SSL Certificates
The “Wildcard” certificate is an SSL type that gives you the most freedom. One wildcard can be used to protect connections for a whole domain and all of its sub domains.
By eliminating the need to manage multiple certificates, wildcard certificates can help your business save a lot of money, time, and effort over time.
We’ll talk about the basics of using a wildcard SSL certificate, like when it’s a good idea and when it’s not.
When should I use a Wildcard SSL Certificate?
SSL Wildcards certificate are great products because they are beneficial and flexible. But there are some times when it could not be a better idea to use a Wildcard.
- You shouldn’t use a SSL wildcard certificate if you need to make a lot of different, highly secure settings. A Wildcard SSL certificate gives the same level of security as any other SSL certificate. Private keys don’t pose any security risks, but there is one possible risk. If you use the same certificate on more than one server, with more than one system administrator, or in more than one department, you risk putting all 13 sites at risk. So, if you work in a field with strict safety rules, you should give each unit and system its certificates and keys.
- You shouldn’t use a SSL Wildcard certificate if you need corporate authentication. At the Extended Validation level, you can’t use wildcards. Regarding security, letting a sub-domain owner host whatever they want is not a good idea. EV SSL calls for the most thorough checks during validation. Suppose you need business authentication, such as the green EV address bar. In that case, sub-domains must be encrypted with either separate certificates or a Multi-Domain certificate that lists the sub-domains as Subject Alternative Names (SANs).
