My office needs to buy an SSL Certificates. There are alot of options out there. From the cheap and pricey. After I googled alot, I found this two SSL Certificates provider. RapidSSL and GoDaddy. Here’s some of pros/cons I found:
– One ROOT CA
– Licensed only 1 server (You can buy addtional licenses though)
– Unlimited Servers
– Chained ROOT (Needs extra steps to install, but if you a geek, it’s no problemo)
Finally I choose GoDaddy. Because in modern browser GoDaddy’s SSL its already built-in.
