Not all SSL are created equal, and lower level or non-compliant SSLs can be blocked. The recent fallout of Symantec’s SSL products and its implication on Amazon’s CloudFront validation
is a prime example of how quickly things can get derailed. To avoid the potential of having to re-install SSLs on hundreds of websites, we only work with a highly respected industry leader for SSL certificates, and it’s not the cheapest in the market.
Also, these SSL price tags you see online presume that you are a web developer capable of installing it, or you will be paying your developer to install it, adding to the costs. Our costs include the installation and maintenance/administration/renewal.
The highest price SSLs are for much higher level validation for e-commerce websites with sensitive data (such as credit card, shipping addresses etc.) and carry large sums of insurance and warranties, which would be an overkill for real estate websites without financial transactions. You don’t need to bring a tank to a gunfight!
