Since the beginning of man, way before the chicken or the egg, the question of whether or not to pay for SSL — and how much does an SSL certificate cost — has plagued us. Aristotle gave lectures about it. Empedocles ruminated on it during his exile. Heraclitus opined in his writings that it was a question that strikes at the heart of every man (and, in 2019, every woman). It’s rumored that Michelangelo’s thinker is pondering that very question from atop his rocky perch.
Since you’re here, we assume that you’ve been shopping around and looking at different SSL certificates to see what the best option would be for your domain or domains. Congratulations! That means either you care about the security and integrity of your site and data — or it means that you know Google has essentially made SSL a requirement for websites to not be marked as “Not Secure.” Either way, we’re just glad you’re here.
There are a variety of reasons why you may want to use two SSL certificates for one domain or IP address. For example, you may choose to install a second SSL certificate to ensure that your site and services don’t experience downtime because your existing certificate will soon expire. Or, you may have one domain hosted on multiple servers and may be using a load balancer.
An SSL certificate is a critical component of website security, facilitating encrypted connections that protect sensitive data in transit. But — and this is a big “but” — the SSL certificates have to be issued by a trusted entity called a certificate authority (CA) for them to be trusted by clients (your users’ web browsers). So, if you’re here because you asked your search engine “what is a self signed certificate,” allow us to explain what this all means for you and why it’s better to use a CA signed SSL certificate over a self-signed one.
Something we get asked a lot is how one would go about changing SSL providers or certificate authorities (CAs). We get it — SSL replacement seems like a pretty challenging task, but it’s really not.
Basically, you just replace the SSL certificate you were using with one from the new certificate authority you’ve chosen. People change CAs all the time. In fact, that’s one of the most common things we help businesses and website with. There are all kinds of reasons to switch CAs.
