Choosing infrastructure intelligence
Passive DNS, WHOIS history, and threat-feed tools all answer pieces of an investigation. WhisperGraph’s difference is that it joins them — DNS, BGP, RPKI, WHOIS, GeoIP, threat intel, and the physical internet — into one graph you traverse in a single query, over Cypher and MCP. Here’s how to weigh the options, and how we stack up against specific tools.
Breadth of the data model
Does it stop at DNS and WHOIS, or also model BGP routing, RPKI validity, GeoIP, threat feeds, and the physical internet — facilities, IXPs, submarine cables?
Pre-joined vs. siloed
Are the layers a single connected graph you traverse in one query, or separate datasets and APIs you integrate and join yourself?
How you query it
A fixed product UI and rigid endpoints, or an expressive query language (Cypher) plus native MCP access so AI agents can investigate directly?
Reproducibility & evidence
Can every verdict be traced to the feeds and factors behind it, and reproduced with a query — or is it a black-box score?
How you start
Is there a genuinely useful free entry point — anonymous queries, a free key — or is evaluation gated behind sales?
