Discovery Guard

ASSET DISCOVERY & BASELINE SYSTEM

Automated discovery of what runs on your network.

Continuous infrastructure inventory, dependency mapping, host security posture, and NIS2 and DORA controls measured on collected data — with two sentinels, Dobermann and Honeypot, watching what an inventory alone cannot see. No inbound ports required.

REGISTER TO TRIAL

30 days of trial with every module. We will ask you to confirm your email with a code; then you will receive the invitation to choose your password.

Why inventories go stale

Not for lack of trying: the inventory was done once, by hand, and the estate kept moving from that day on.

“The asset spreadsheet is two years old.”

A manual inventory is accurate on the day it is closed.

“We don’t know what stops if that server goes down.”

The gap is dependencies, not assets.

“We pay licences for machines that no longer exist.”

The asset register no longer matches reality.

“We’ve been asked to demonstrate NIS2 compliance.”

The directive requires knowing what you have before protecting it.

Four capabilities usually bought separately

One platform collects the inventory automatically and on a schedule, reconstructs dependencies, and builds the rest on top.

CMDB

What is deployed, how it is configured, how it changed, what depends on what — with history, because the real question is what changed.

Asset and capacity register

Owner, cost centre, value, contracts and warranties approaching expiry — and how much headroom is left.

Traffic

What talks to what, and what the network exposes.

Security, compliance and active defence

Host posture, NIS2 and DORA on the same data — plus Dobermann and Honeypot.

And an audit trail underneath all of it: who signed in, and who changed what. It is the first line an auditor asks for.

Three components, one direction of traffic

outbound only · HTTPS + mTLS

The probe

Runs inside your network and performs the scans. It exposes nothing and accepts no connections.

The control plane

Receives, normalises, reconciles and stores. It never initiates a connection towards your network.

The console

Where the data is reviewed, scans are planned, and the result is taken into a meeting.

No inbound ports to open. No VPN into your network. Multiple probes per customer, with automatic job failover: if one stops, the work moves to another.

Everyone shows a green percentage

Censo declares what it could not measure. It is not a footnote: it is a product decision, enforced in four separate places.

“Not applicable” is not “not assessable”

Backup is not required of a printer. Missing data is a different thing — and the reason states how to obtain it.

CVEs with the denominator

No vulnerabilities across 4 recognised of 380 and none across 380 of 380 read identically without that number.

The fact, not the verdict

Not “Telnet is enabled”, but telnet listening — port 23, observed 06/09. Ten seconds to verify.

A truncated list says so

In a security context, “nothing found” quickly becomes “nothing there”.

Four outcomes, not three

A real card: four controls on one host, each with its reason next to it and the denominator at the bottom. The not assessable row is the one no other product shows, because it lowers the score.

Sources, one console

The list is not the argument. The argument is that they sit in one place: bought separately, they end up in four consoles that do not talk to each other.

SSH, WMI over DCOM, remote registry

Agentless by default. The agent exists only for machines that cannot be reached any other way — vendors who sell agents have to ask you to put one on everything.

Run a trial on a single site

We call you back within one business day and agree which site to use. You provide a machine on the network and a read-only SNMP community: we handle the rest.
