Endpoint and AI agent security
See who is really on the other end.
Then cut them off.
Every host your people and AI agents touch resolves to a real owner, a real network, a real jurisdiction. On a graph of 56.6B data points, Whisper shows you which ones you should never be talking to, and blocks them at the connection.

The answer 3 / 3
- Behind the proxy
Every IP and domain resolves to its real owner, network and jurisdiction.
Even through a CDN, a hosting reseller or a shell company. The proxy in front is not the answer.
- The whole estate
One indicator expands into the whole estate in a single query.
Shared certificates, co-hosted domains, same registrant, same network, same pattern.
- Before it connects
Graph XDR turns the answer into a rule your network enforces.
Block by owner, jurisdiction or sanctions list. At DNS and egress, before the connection exists.
Example result
- The link
- 4 hops away · AS64511 · Seychelles
- Who is behind it
- A shell company, behind a CDN
- Everything else they run
- 9 domains · 2 certificates · 5 addresses
- Action
- Owner and estate blocked at DNS and egress
Cut off for every endpoint and agent.

- Problem
- Are you exposed to this vendor, jurisdiction or incident? The honest answer takes two days, with caveats.
- Today
- Questionnaires the supplier filled in, a spreadsheet, and a scanner that stops at your perimeter.
- With Whisper
- We know who it is and where they reside.Every vendor and dependency resolves to its owner, network, jurisdiction and facility. Continuously.
- Outcome
- You answer in the meeting, with evidence an auditor accepts.
- Problem
- The alert is an address and nothing else. The one that matters looks like the other thirty nine.
- Today
- WHOIS, DNS history, certificates, reputation, then a guess. Forty times a shift.
- With Whisper
- Context is in Splunk, Sentinel or OpenCTI before you open the ticket. One pivot returns the whole cluster.
- Outcome
- Three addresses classified with full evidence in eight seconds. By hand, forty five minutes.
- Problem
- Your agents reason about infrastructure they cannot see, and leave as cloud IPs you cannot tell apart.
- Today
- Scraped feeds, a brittle enrichment pipeline, and an allowlist that is wrong by Friday.
- With Whisper
- One MCP endpoint the agent queries mid-task, plus a routable identity and egress policy per agent.
- Outcome
- Agents that know what they talk to, and an off switch for one that leaves the fleet alone.
- Problem
- You cannot tell a client how many AI agents run in their business, who started them, or what they reach.
- Today
- Allowlists wrong by Friday, one console per client, and rules that only speak in addresses.
- With Whisper
- An identity for every agent and device, tied to whoever launched it. Policy as logic: “nothing owned by a sanctioned entity, wherever it is hosted.”
- Outcome
- A client fleet enrolled in an afternoon. Shadow AI answered with a number. Rules that hold when addresses change.
Where it is used
6 different use cases. One query language.
Every one of these is the same question asked at a different layer.
AI Agents & Endpoints
Give every agent and endpoint an identity, and a policy you can write in owners and jurisdictions.
SOC Optimization
Alerts arrive already scored against the whole graph, inside the SIEM you already run.
Threat Hunting
Pivot one indicator into the adversary’s whole estate, including the parts they have not used yet.
Brand Protection
Find the lookalike domains your own customers could not tell from yours.
Supply Chain Risk
See which of your vendors quietly share a provider, a facility or a cable.
Critical Infrastructure
For OT networks where the address is clean and the consequence is physical.
Why teams trust it
We run the network we are telling you about.
Whisper operates its own RIPE-allocated autonomous system, AS219419. Everything we claim about routing, you can check yourself.
