Startup Idea: Customizable Internet Filtering Software

Startup idea to develop a software allowing parents to customize internet filtering for their household. The software would allow them to customize access levels varying by websites, providing greater control over internet filtering.

I could use software to customize internet filtering for my household. I subscribe to a service but I found it too strict with sites I allow but when I let go of some of the commands, it allowed too much internet through without enough filtering.

I wish there was a way to customize and sort of 'whitelist' sites I allow my kids to use while filtering others.

I find that all internet filters are either too strong or not strong enough and I'd like to choose different levels of filtering depending on the website being used at the time. I've used a couple of filtering services but none are just right for our family.
