Find Your Solution

What are you trying to build?

Pick the line that sounds like your problem — each one goes straight to the product that solves it.

I need an offline database of categorized domains — for internal applications or as part of the infrastructure serving my clients

Download pre-classified domain datasets — from 1 million up to 120 million domains — with IAB categories, web filtering tags, personas and popularity data. Everything runs on-premise inside your infrastructure, so no lookup ever leaves your network, with regular update deliveries. Redistribution licensing is available if the data powers a product you sell to your own clients.

I'm building web filtering — parental controls, a secure gateway, DNS filtering or network policy

Our web filtering taxonomy covers adult content, gambling, drugs, weapons, violence, malware and the other categories acceptable-use policies are built on. Take it as an offline database for zero-latency local lookups, or call it in real time for the long tail of unknown domains.
