# What Is Infrastructure Intelligence?

> Infrastructure intelligence is the real-time collection, correlation, and analysis of internet infrastructure data — BGP routing, DNS, hosting, WHOIS, DNSSEC, certificate transparency — so security teams can detect, attribute, and respond to threats based on how attackers actually deploy their tools.

## Why Traditional Threat Intel Falls Short

Threat-intelligence feeds publish lists of bad IPs, bad domains, bad hashes. Useful — but they describe what an attacker did *yesterday*. Infrastructure intelligence describes the substrate the attacker is using *right now* and what they will likely use tomorrow, because campaigns leave fingerprints in the routing, naming, and hosting layers that survive any single IOC rotation.

## What Goes Into the Picture

- **BGP routing** — which ASNs announce which prefixes, how routes change over time.
- **DNS** — every hostname's resolution history, every zone's nameserver, every CNAME chain.
- **Hosting and IP allocation** — who actually operates a given IP at a given moment.
- **WHOIS / RDAP** — who registered a domain, with what email, on what date.
- **DNSSEC posture** — which zones are signed, with which algorithms.
- **Certificate transparency** — every TLS certificate ever issued for a hostname.
- **Threat feeds** — overlay of known-bad activity from intelligence partners.

## What Infrastructure Intelligence Lets You Answer

- "Which other domains share a nameserver with this known-bad domain?"
- "Which IPs has this domain ever resolved to in the last five years?"
- "Which ASN currently announces this prefix, and which announced it before?"
- "Which of our vendors deploy DNSSEC and which do not?"
- "What does a typical DGA-generated domain registration footprint look like for this actor group?"

## Why a Graph, Not a Database

Most of these questions are multi-hop. They start with one entity (a domain, an IP, an ASN) and ask for everything reachable from there along specific relationship paths. That's a graph problem. Storing the same data in a relational database forces every traversal into expensive joins.

## Whisper as Infrastructure Intelligence

[Whisper](https://www.whisper.security) is built around exactly this idea. A custom graph engine, billions of internet-infrastructure nodes and edges, real-time ingestion, and query interfaces for both analysts (Cypher / REST) and AI agents (MCP).
