## The internet is one system. Its data is not.

Routing, DNS, hosting and ownership data sit in separate databases, so a security team that needs to connect a domain to the network behind it does the joining by hand. We are building the intelligence layer that connects them: one graph, served by [an engine built for it](https://www.whisper.security/products/engine).

We think understanding the infrastructure is how you defend it, and the people who ran parts of that infrastructure are the ones to map it.
