Prince of Persia: mapping the backend, and a reserve of domains staged for what comes next
An investigation into Prince of Persia’s backend infrastructure, revealing a previously unreported server, 58 dormant domains, and DNS patterns that can expose potential C2 infrastructure before activation.

The infrastructure you depend on but don't own
A single DNSSEC failure at Germany’s .de registry made millions of domains unreachable. The outage shows how infrastructure you don’t own can still become part of your attack surface

What an ASN actually is
Every IP belongs to an Autonomous System. Understanding ASNs is the first step to uncovering infrastructure relationships, tracing attacks, and investigating the internet beyond individual domains.

Every World Cup Threat Report Is a Starting Point
World Cup phishing campaigns are already scaling before kickoff. Whisper’s MCP turns public threat reports into actionable infrastructure investigations by uncovering the domains, hosting, DNS, and relationships hiding one layer deeper.

Concentration risk: when half the internet depends on three companies
Modern infrastructure looks distributed—but often isn’t. Hidden dependencies across cloud providers, DNS, and routing create concentration risk that most organisations can’t see until systems fail together

Your AI agent is only as smart as what it can see
AI agents don’t fail because of reasoning—they fail because of missing context. Without structured, connected infrastructure data, they can’t see the relationships that turn lookups into real investigations

Tools
Work with WhisperGraph and Whisper Graph XDR directly. Some need a free account, some need nothing at all.

Whisper Console
The graph, explorable.
Explore WhisperGraph visually, run Cypher queries and prepared workflows, and manage your API keys, all in one place.
Sign in freeExplore the Console

Whisper Atlas
The internet's infrastructure, mapped.
Fly from submarine cables and landing stations down to a city's data centers and the address blocks inside them. Search a domain, an address or a network to see where it lives.
Sign in freeOpen Atlas

Graph XDR console
The operator console for Whisper Graph XDR.
Run Whisper Graph XDR across a fleet from one screen: identities, policy, incidents and the campaigns behind them. Every endpoint and agent carries its own routable IPv6 identity that anyone can verify.

Whisper Guard
A verdict on every site you open.
A browser extension that puts a mark in your toolbar on every page. It checks the site's name against imitated brands on your device, then against the Whisper graph. Only the hostname ever leaves your browser.

Whisper Projects
Free public services the Whisper team runs on the same graph. None of them needs a sign-in.

Whisper Internet Directory
A citable page for every host and network.
The Whisper Internet Directory gives the hostnames and networks on the graph a stable page you can cite: a plain summary, the threat posture and a nutrition label. Bookmark one, or link it from a report.
