Whisper maps the internet as one connected graph and uses it to decide what your machines and AI agents may reach. The graph joins routing, DNS, hosting, ownership, certificates and intelligence feeds into linked records you can query from any domain, IP or network. Two products run on it. Whisper Graph XDR gives each machine an identity, applies policy to where it connects, and cuts it off from outside the host. Whisper Intelligence tells you who is on the other end of any address.

Traditional threat intelligence gives you flat lookups — one indicator, one record — and leaves you to stitch the picture together across several tools. Whisper pre-joins DNS, BGP, WHOIS, hosting, and threat intel into one graph, so you pivot from any indicator to the whole connected picture in a single query — and see infrastructure as it's built (shared nameservers, registrant reuse, new prefixes, BGP changes), not just what's already been reported.

Security teams that need to know what is on the other end of a connection and control where their machines and AI agents connect. That includes SOC and threat-intel teams, security leaders, engineers building AI agents, and managed security providers.

Start free. Send a query to the graph with no key, or create a free account to get a key for the API, the Console and the MCP server. Graph XDR starts free too. If you would rather see it first, book a demo with the team.

We describe our security as things you can check from outside, not as badges. The graph, the query API, the MCP server and our data stores run on servers in the EU. Our customer-facing endpoints use TLS, access to operational systems is restricted and audited, and API keys are never written to our logs. The trust page lists what you can test, and the privacy policy sets out what we collect and why.
