Let’s say you spend a bunch of money running an ad campaign, build a useful website specifically for that ad, set up an SSL certificate so the site is nice and safe and when somebody types PlanWithEase.com into there address bar after seeing the ad, the visitor is presented with an "Unsafe Site" message?
What are you going to do? Leave like I did? I bet a good deal would and often DO!
So why is a site being promoted by a large company like ING Group, Inc (ing.com) not considered safe?

Because the cNAME record is wrong! In the end, this is a simple cNAME record issue and not really an SSL problem but the error is one that often times are made by companies.
PlanWithEase.com is one way people type in a domain name.
www.PlanWithEase.com is another.
PlanWithEase.com and www.PlanWithEase.com are two different domain names really. www. is a sub domain and not resolving BOTH domains to the same location is a problem. It is a bigger problem if your domain name without www. doesn’t resolve, because your site will likely not resolve either!
Since in this case the site uses an SSL certificate, the certificate is set up as a "Wild Card" and hence the * before the domain name: *.planwithease.com
Using the wild card is smart as it covers all sub domains, but it doesn’t cover the domain without a sub domain! The problem, the SSL is NOT including the domain name WITHOUT the www. . Since the wild card is set up for sub domains, PlanWithEase.com does not have a sub domain and is not included in the SSL. If cName records were correct, then when somebody simply typed in the address bar PlanWithEase.com, the domain name would automatically "redirect" to www.PlanWithEasy.com! The domain with the sub domain also happens to be covered by the SSL certificate and the error type message would not be displayed.
cNAME records are often done with your hosting provider or domain name registrar. You should be able to set up a redirect in your hosting account, to send non www. domain traffic to the www. domain or vice versa.
The above image is because the site uses an SSL, but if they didn’t, the users entering in the domain name without www. would simply get an error that the domain name does not resolve. Lost traffic, lost trust and lost customers are often the result of this very easy to fix error.
