Endpoint and AI Agent Security

on the other end.
Then cut them off.

Whisper holds the internet as one graph, so one query shows everything an address touches, and one command cuts it off. Most teams start by investigating, then build, then move to control. Nothing forces the order and nothing gets replaced.

intelligence feeds, joined in one graph

Measured

Three ways in. One graph behind them.

Drops into the stack you already run, with nothing to rip out.

  1. Investigate

    See who is behind any IP, domain or network, and everything else they run, in one query.

    Whisper Intelligence, in the console and the SIEM you already run.

  2. Build

    Put the same graph inside your own tools and AI agents through the query API, the CLI and the MCP server.

    The engine both products run on.

  3. Control

    Turn the answer into a rule enforced at DNS and egress, and cut a host off from outside the box.

    Whisper Graph XDR, for endpoints and AI agents.

What happens when you ask about an address

DNS, BGP, WHOIS, certificates, hosting and intelligence feeds are joined before you ask, so one lookup crosses all of them.

  1. Ask

    Type a hostname, IP, ASN or CIDR block into the console.

    Or send it from your own code, through the query API or the MCP server.

  2. Resolve

    One traversal returns the owner, the network, the building it sits in and whatever shares them.

    Five layers in one statement, with no joins to write.

  3. Act

    Send the verdict to your SIEM, or turn it into a rule that blocks the host at DNS and egress.

    An analyst and an agent read the same answer.

From one vendor name to a decision

A vendor turns up in a review with nothing but a name. This is what the graph returns.

  1. The name

    acme-vendor.com is all you have. Nothing yet says who runs it, or from where.

    A stand-in for a vendor of your own.

  2. The chain

    It resolves to ALEXHOST SRL on AS200019, in Moldova, at the Trabia facility.

    Flagged by the graph for bulletproof hosting.

  3. The decision

    Owner, network, country and facility arrive together, with the path that produced them.

    Enough to open a ticket that anyone can check.

Same graph. Very different Tuesdays.

Pick a seat.

MSSPs & MDR
Multi-tenant · MDR

OutcomeYou enrol a client fleet in an afternoon, answer the shadow-AI question with a number, and enforce a rule that stays true when the addresses change.

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.

AS219419 · verify on RIPE

  • Our own network

    AS219419 is RPKI signed and MANRS compliant, and announces its prefixes into the same public tables the graph reads.

  • An advisory board you can look up

    Geoff Huston of APNIC, Jeff Osborn of ISC, former ICANN board chair Maarten Botterman, Merike Kaeo and Jonathan Cave.

    Meet the board

  • Founded by the architect of K-root

    Kaveh Ranjbar, our co-founder and CEO, was CIO of RIPE NCC. K-root is one of the internet's thirteen DNS root servers.
