An anonymous reader writes "I have recently been tasked with switching our SSL certificate provider and it's proving not to be easy. We use an internal authority for our own stuff and then we buy certificates to protect outward-facing sites (a lot of them). My question for this community is: How do you choose a certificate authority to use? There is price, service (why we're leaving our last vendor), warranty, and products offered as the only differentiators I can find. Is there any public resource that would show me actual customer reviews of CAs like Verisign, GeoTrust, Comodo, Trustwave, and DigiCert? Our last vendor did a really poor job with support and I would like to make a reasonably educated decision."
