USE CASES For a million reasons. Here's a few.
This is a common pattern ('We serve everyone!'), but you'd be well advised to actually pick a use case early on - you'll find that ecom, gaming, finance (especially), content, security, marketing all have their own specific needs and requirements, and they will want to see how you fit them before signing up.
This also makes your marketing efforts a little easier, as instead of having to spread thin across six different verticals, you can target for instance communities of indie gamers, bloggers, small shops who face this problem. when you've got validation from one of these, its easier to scale, but trying to go too broad too early in targeting is one of the most common errors founders make.
nicely designed site though and a lot of other stuff is on point.
EDIT: Your branding is also a little opaque. I wouldn't naturally associate "visitorquery" with what you were trying to do. Going for a domain like detectvpn even if you had to drop down to something like detectvpn.me feels like more of a direct match.
