One of the many things I do for my company, and did for my previous company, is manage web servers. Many of these web servers have sites secured by SSL, which means that I frequently have to purchase SSL certificates. Because of this, one of the things I find myself doing a lot is checking the vendor of SSL certificates for sites I go to. I just like to see what everyone is doing.
For instance, Facebook and Twitter buy their SSL certificates from Verisign, and Gmail is protected with a Thawte certificate. My company likes to use GoDaddy certificates because they were the cheapest for the longest time, and the VoIP company we use likes Digicert. Now Verisign, Thawte and Digicert have been around for a long time, and they charge a hefty fee for their name, but in reality, they don't secure things any better. SSL is a standard, not proprietary, so the actual encryption you get from Verisign is not really any better than GoDaddy's.
So that brings me to my next point, if the company doesn't matter, then why pay so damn much? I found a company that sells SSL certificates for probably the cheapest you will find anywhere without a promo code, or special offer. It's NameCheap! NameCheap is a registrar similar to GoDaddy, except they never once supported SOPA. Besides that they have the best deals on SSL that I've ever seen! Standard SSL certs from Comodo are as low as $7.95 per year, and wildcard certs are as low as $89.99 per year! Compare that with Verisign or Digicert!
The next time you need to purchase an SSL cert, buy them through NameCheap and save a few bucks.
