We use the Green, Yellow and Red system to track priorities of scanning results. 

A green page indicates that the results are good, we did not detect any errors, problems or impersonations on the destination system. 

A yellow page indicates that the results are questionable or that we had a problem with the destination system.  These errors may include the remote system blocking our crawler, to many redirects or a slow response from the destination system.  Take caution when viewing these pages. 

A red page indicates that we have detected an issue on the site. This may include a logo mismatch, a login screen that seems to be out of sync with the site or other elements that may indicate a phishing site.
