Agentless Datacenter Detection & Response

Your EDR stops at the OS.
Your adversary doesn't.

The hypervisors and control planes that run your datacenter are where advanced adversaries hide — below the reach of CrowdStrike and SentinelOne. TensorOne watches that layer without installing anything on it: one collector, passive syslog, read-only API polling, nothing on your hosts and no change window.

The same edge filter that feeds it drops up to 99% of datacenter log volume before it ever reaches your SIEM — which is usually enough to pay for the detections outright.

The blind spot

The most valuable machines in your datacenter are the ones nothing is watching.

A hypervisor can snapshot, clone, or wipe every workload you run — yet no endpoint sensor can live on it. That's true on every platform: whether it's VMware, Proxmox, Nutanix, OpenShift, or your cloud.

So attackers who reach the datacenter's control layer operate below the floor your EDR is standing on — and as the industry migrates off VMware, the blind spot simply follows you to the next platform.

The industry’s answer is to spend more every year. It isn’t working.

3RD
If cybercrime were a country, its $10.5 trillion economy would rank the third-largest on Earth — behind only the U.S. and China, and more profitable than the entire global trade in illegal drugs combined.
Break the cycle. TensorOne cuts your datacenter log bill and detects what EDR can’t reach — so the coverage you are missing is funded by the spend you are already making.
The Solution

Coverage where it's dark. Detection where it counts.

Detections written by the other side

Behavioral detections tuned to each platform's control layer, written by former NSA specialists who spent their careers learning how intruders stay invisible at this layer — and revised as tradecraft shifts.

AI-assisted triage

Agents correlate related events, suppress known-benign patterns, and draft detection candidates — which our engineers review before anything reaches your console.

Generative hunt copilot

Interrogate your entire datacenter in plain language — ask where a process ran, who authenticated, what changed — and get the answer with the evidence attached.

Every platform, one console

VMware, Proxmox, Nutanix, OpenShift, KVM, and cloud control planes — unified under a single pane. Migrate off VMware and your detection coverage moves with you instead of starting from zero.

The edge filter that pays for itself

Up to 99% of datacenter log volume dropped before egress — a live meter shows, to the dollar, what that removes from your SIEM bill. Usually enough to fund the detections outright.

Live inventory & forensics

A real-time map of every host, cluster, and appliance across your datacenter — with retained forensic detail on the events that matter, so you have the evidence when it counts.

Who we are

The people who wrote the playbook you're defending against.

To catch an adversary who knows how to evade detection, you need the people who spent their careers doing it. Here's exactly who that is.

Isolation & trust

Your telemetry never shares a table with anyone else's.

Isolation isn't a setting we bolt on — it's the architecture. Every organizational context is scoped, access is bound to identity, and your data stays yours.

01

Per-context database isolation

Each organizational context — a subsidiary, a datacenter, a business unit — gets its own dedicated database. No shared tables, no row-level co-mingling.

02

Identity-bound access

Tenant scope is cryptographically bound to the authenticated session. It can't be reassigned by a client, so a user only ever sees the contexts they're granted.

03

Dedicated infrastructure

Regulated workloads run on infrastructure dedicated to your organization, with data residency to match your obligations — not a shared pool.

04

Filter on-prem, by design

Raw telemetry is filtered inside your network. Only the signal you approve ever leaves the building — the rest never crosses the boundary.

05

Silence is a detection

The obvious move against a passive collector is to stop feeding it. We track expected volume and heartbeat per host, so a source that goes quiet raises an alert instead of leaving a gap — including when someone turns syslog off.

06

Read-only, and we'll prove it

Inventory and configuration state come from read-only service accounts. The complete permission list is a one-page document we send before you grant anything — your security team reviews it first, not after.

What the filter is worth

Put your own numbers in.

Most of what your hypervisors and control planes emit is noise your SIEM still bills you to store. Enter your ingest and rate to see the annual cost our edge filter takes off the table — then get the seven-day assessment to replace this estimate with a figure measured on your own telemetry.

Measure your real number →

An estimate from the numbers you entered. The seven-day assessment reports the reduction actually measured on your telemetry — never an average from our lab.

How you start

Seven days of your logs. No purchase order.

Before anyone talks about contracts, we measure what your datacenter layer is actually costing you and what is already hiding in it. Nothing gets installed on a hypervisor to do this.

You

Point syslog at one VM

A single configuration line on your hosts, reversible in seconds. No agents, no VIBs, no kernel modules, no change window, nothing installed on the hypervisors themselves.

Us

Seven days, then a written report

Your real ingest volume and what it costs at your SIEM's rate, the share we would filter out, and anything already anomalous sitting in that telemetry.

Then

You decide with your own numbers

If the report is not compelling, we part ways and you keep it. If it is, we scope a deployment against figures from your estate instead of averages from ours.

No cost, no procurement, no commitment — the assessment is a measurement, not a trial. Book the scoping call →

If we don't cut your hypervisor ingest by 50%, you don't pay.

Hunt the dark layer

Catch what your EDR can't see.

Start with seven days of your own telemetry. Stand up one collector, watch the noise fall away, and see what has been running underneath your EDR the whole time.
