I will post TPs reply here for general understanding for others as well, on how the HomeShield+ is designed to work:
Thank you for contacting TP-Link support.
Frankly speaking, I'm afraid the Forcepoint URL Database can't be the only standard to judge if the security web protection take effects or not.
Our homeshield function are in cooperation with Avira, and you can test with the security harmful websites in Avira database.
Definitely you are not paying for nothing and you can test with some other known harmful websites. We would promise that.
An my thoughs on that reply:
The Forcepoint database is only one example of test URL database. They provide their service based on the Internet URL categorization principle where certain URLs are put into a matching URL category.
I would assume that TP Deco's HomeShield via Avira does the same thing when talking about URL protection. It is clear that Avira does not share the same base URL category list as some other providers out there. Thus I would be interested to see URL categorization database used by TP/Avira that is used to provide the website protection services on Homeshield+.
Thus my question still remains the same: Am i paying for nothing ? What is the added value of HomeShield compared to installing free Avira to my device ?
