secnostic inventory
models machines, controllers, HMIs, lines, zones, communication paths, and lifecycle data.
Manufacturing without blind spots
secnostic shows which machines, controllers, HMIs, engineering systems, and suppliers a line really depends on. Your team finds incidents faster, plans maintenance more cleanly, and keeps cyber risk in check without slowing production down.
For plants, lines, machine fleets, and organically grown OT.
See what runs on the line, without touching it
On a live line, even looking is a risk. The sensor observes network traffic passively and places every device in its IEC 62443 zone and Purdue level, because in OT availability and safety come before everything else.

What this covers
In manufacturing, the useful view is not the longest asset list. It is a dependable view of lines, machines, controllers, OT assets, communication paths, and maintenance windows. OT architecture, NIST SP 800-82, and IEC 62443 make that operating data useful for risk and evidence work too.
A line depends on machines, controllers, HMIs, engineering workstations, historian systems, IIoT gateways, and cloud connections. Without a shared OT view, dependencies, remote maintenance, and firmware states stay in the dark far too long.
Outcomes
- faster root-cause work because lines, facilities, communication paths, and owners are known
- better maintenance and patch planning with a view of criticality, firmware, EOL/EOS, and production windows
- less manual list maintenance, because secnostic discovers continuously and reconciles with existing sources
What a blind spot on the shop floor costs
Unknown OT is attack surface, downtime risk, and audit gap all at once.
Shadow OT and foreign devices
Undocumented machines, integrator laptops, and IIoT gateways are often the first way into the production network.
Firmware with no update path
Controllers run past EOL/EOS, and a patch needs the machine builder's sign-off.
A vulnerability with no context
A vendor advisory helps little until someone knows which line and which PLC it actually affects.
Observe, understand, act
The setup is the same in every plant. The secnostic sensor observes network traffic passively and reports only what it sees. Active queries run only after approval.
The inventory graph places every device in its line, zone, and Purdue level and links it to firmware, vulnerabilities, and owners. focusAlert takes the relevant finding to the right person with a traceable history, while the decision to patch or compensate stays with the asset owner.
In practice, four situations
What happens when something changes on the plant floor? Each situation as a concrete flow.
- NoticeThe sensor sees a previously unknown device on the production network without querying it actively.
- Place itThe graph locates it by line, zone, and Purdue level, and proposes an owner.
- AssessOpen ports, protocols, and known vulnerabilities are tied to production criticality.
- ResolvefocusAlert hands the finding to OT and plant management, with a traceable history.
- AdvisoryA vendor or CERT advisory arrives, often with no link to your own equipment.
- Find the hitsThe graph shows at once which PLCs, HMIs, and lines run the affected version.
- PrioritizeExposure, zone, and production impact decide between patching, segmenting, and compensating.
- DecideThe action stays with the asset owner, with context instead of gut feeling.
- AccessAn integrator or maintenance partner connects to a machine or over a remote path.
- Make it visibleThe conduit is recorded in the model with purpose, owner, and time window.
- ObserveThe sensor detects new devices or communication paths the access brings with it.
- Keep a recordActivity and changes stay provable, even after the maintenance window.
- CandidatesDue patches, EOL systems, and open actions are grouped by line.
- WeighAvailability, safety, and vendor sign-off are set against the security effect.
- BundleActions go into the next real maintenance window instead of disrupting one by one.
- ProveWhat was done, deferred, or compensated stays traceable for IEC 62443 and NIS2.
Which product modules are involved
The modules play different roles in the deployment: observation, inventory, platform governance, and handover to the right people.
FAQ
Key questions before a first scoping conversation.
Why is OT transparency operationally important in manufacturing?
Production teams need to quickly see which line, machine, controller, connection, or remote-maintenance path is affected. An OT view reduces search time during incidents and makes maintenance, segmentation, and security measures easier to plan.
How does secnostic avoid disrupting production during discovery?
The entry point is passive-first. Sensors observe existing communication; active queries are used only in a controlled and approved way, so production, safety, and maintenance windows are respected.
How does secnostic help with vulnerabilities and EOL/EOS?
secnostic connects CVEs, vendor advisories, firmware, support status, exposure, and production criticality. Teams can see where patching makes sense and where segmentation, access restriction, or compensation is a better fit.
Are IEC 62443, NIS2, and audits still covered?
Yes. Zones, conduits, asset management, risk assessment, measure status, and ownership become traceable and exportable from operational work.
Make the OT state of the plant visible
We start with one line, one plant, or one concrete vulnerability situation and show which data becomes useful for operations, risk, and evidence immediately.
