I recently had an issue where I released software which made use of a new URL and several of my customer sites complained that the software wasn't working within their wifi network. It turned out that their respective Firewall software products of choice (some were using BlueCoat, others ForcePoint, Barracude, etc) were all blocking my new URL because it was categorized as "New" or "Unknown" or "Untrusted" or something.
My question is - What is the authoritative source of these categorizations? They all seem to agree on my new URL's category, so are these products all using the same central authority (Google?) for categorization? Is there some authority or organization I could have reached out to to get my URL categorized correctly before releasing my software?
I don't want all of my customers to have to add firewall exceptions in cases like this.
