Detection and response for the layer your EDR can't reach.
Hypervisors, control planes and management interfaces run the most valuable machines you own, and endpoint tooling cannot see any of them. TensorOne watches that layer: behavioral detections mapped to MITRE ATT&CK, multi-stage correlation that reconstructs a kill chain instead of alerting on each step in isolation, and response playbooks for what it finds.
The detections are engineered by former NSA operators, and the platform was designed from the ground up by one of them.
Nothing is installed on your hosts to do it, and it funds itself: the same edge filter that feeds the detections drops up to 99% of your datacenter log volume before your SIEM bills for it. Guaranteed 50% or you don't pay.
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: VMware (Broadcom), Proxmox, Nutanix, OpenShift, KVM, or your cloud.
And organizations don't migrate off one platform onto another. They run several at once, for years. Each has its own control plane, its own logging format, and its own security model. EDR covers none of them, and a single-platform tool covers a fraction of the estate.
You're not running one hypervisor. You're running three. What's watching all of them?
In public federal contract records for FY2025–26, 33 of 62 agencies with a measurable virtualization estate bought two or more virtualization platforms in the same two-year window. Twelve bought three. One bought four.
The industry’s answer is to spend more every year. It isn’t working.
On pace for $16.89B by 2030.
Headed for $15.6T by 2029 — and still climbing.
Coverage where it's dark. Detection where it counts.
Detections written from the offensive side
Behavioral detections for the hypervisor control layer, each mapped to its MITRE ATT&CK technique and carrying a severity that states the expected response window. Written by former NSA operators who spent their careers learning how intruders stay invisible at this layer, and revised as tradecraft shifts.
Kill chains, assembled
Multi-stage correlation links a brute force, a successful login from the same user and address, and the high-risk command that follows into one incident — with the time delta between each stage and the evidence attached to every node.
Authentication analysis that knows your clock
Off-hours logic runs in your own timezone, handles night shifts that wrap past midnight, exempts the service accounts that are supposed to run at 3 a.m., and declines to judge at all when the source clock has drifted more than two hours from ours.
Response playbooks for what it finds
Every detection ships with the response playbook for the technique it catches: what to contain, what to preserve, and what to verify before you call it closed. Written by the operators who wrote the detection.
Six source types, one console
Collects from VMware (Broadcom) vSphere and vCenter, Proxmox VE, Nutanix AHV, Red Hat OpenShift, KVM/libvirt and AWS CloudTrail at the same time, with live inventory and exposure matching across all of them. Behavioral detection content is deepest on vSphere and ESXi.
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.

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.
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.
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.
Dedicated infrastructure
Regulated workloads run on infrastructure dedicated to your organization, with data residency to match your obligations — not a shared pool.
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.
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.
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.
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.
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. Filtering alone is our entry tier, Delta — $100 per host per year; what it saves is how most customers fund the full detection platform.
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.
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.
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.
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.
Detection first. The filter pays for it.
And if we don't cut your hypervisor ingest by 50%, you don't pay.
Cut your SIEM bill today.
Expert-crafted filtering keeps only the telemetry worth paying for and stops the bleeding on ingest costs — for less than the noise from a single host costs you now.
Eagle processes only what Delta forwards, so upgrading isn't a second deployment or a new change window — it's rewriting the destination on telemetry already flowing.
Start with filtering. Turn on detection whenever you're ready.
