secnostic inventory
models machines, controllers, HMIs, lines, zones, communication paths, and lifecycle data.
Manufacturing without blind spots
secnostic® shows which machines, controllers, HMIsAn HMI is an operator interface through which people observe and control machines, plants, or processes., 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.

Outcomes
- faster root-cause work when a line stops
- maintenance and patches planned by criticality, firmware, and EOL/EOSEOL/EOS describes lifecycle states in which a vendor no longer regularly maintains, sells, or supports a product, firmware, or system.
- less manual list work, because secnostic® reconciles continuously

Shadow OT and foreign devices

Firmware with no update path
Controllers run past EOL/EOSEOL/EOS describes lifecycle states in which a vendor no longer regularly maintains, sells, or supports a product, firmware, or system., 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.

Passing sensor data to inventory requires a configured integration. A configured webhook/API connection can pass events to focusAlert. This integration is optional.
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, zoneZones & Conduits is an IEC 62443 concept that groups systems with similar protection needs into security zones and describes permitted communication paths between these zones as conduits., and Purdue level, and proposes an owner.
- AssessOpen ports, protocols, and known vulnerabilitiesA vulnerability is an exploitable weakness in software, hardware, configuration, process, or architecture. are tied to production criticality.
- ResolveAn optional configured connection to focusAlert passes the finding to OTOT covers hardware and software that monitor and control physical devices, plants, processes, or infrastructure. and plant management, with a traceable history.
- AdvisoryA vendor or CERTA CERT is an organizational point of contact that receives, assesses, and coordinates security reports and publishes warnings or advisories. advisory arrives, often with no link to your own equipment.
- Find the hitsThe graph shows at once which PLCs, HMIsAn HMI is an operator interface through which people observe and control machines, plants, or processes., and lines run the affected version.
- PrioritizeExposure, zoneZones & Conduits is an IEC 62443 concept that groups systems with similar protection needs into security zones and describes permitted communication paths between these zones as conduits., and production impact decide between patching, segmenting, and compensating.
- DecideThe action stays with the assetAn asset is a physical or digital element that is relevant to operations, control, monitoring, or security. 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, EOLEOL/EOS describes lifecycle states in which a vendor no longer regularly maintains, sells, or supports a product, firmware, or system. 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 62443IEC 62443 is a series of standards for cybersecurity in industrial automation and control systems. and NIS2NIS is the European legal framework for a higher level of cybersecurity in network and information systems..
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 OTOT covers hardware and software that monitor and control physical devices, plants, processes, or infrastructure. view reduces search time during incidents and makes maintenance, segmentationSegmentation divides a network into bounded areas so that data flows, access, and risk become more controllable., 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 CVEsCVE is a public identification system for known cybersecurity vulnerabilities., vendor advisories, firmware, support status, exposure, and production criticality. Teams can see where patching makes sense and where segmentationSegmentation divides a network into bounded areas so that data flows, access, and risk become more controllable., access restriction, or compensation is a better fit.
Does secnostic help with IEC 62443, NIS2, and audits?
Yes, with the documentation. ZonesZones & Conduits is an IEC 62443 concept that groups systems with similar protection needs into security zones and describes permitted communication paths between these zones as conduits., conduits, assetsAn asset is a physical or digital element that is relevant to operations, control, monitoring, or security., risk assessmentA risk assessment evaluates threats, impacts, and protection needs so security measures are set based on risk rather than uniformly., measure status, and ownership become traceable and exportable from operational work. The evidence an audit requires depends on the applicable framework and your deployment.
Which integrations need to be configured?
Passing sensor data to inventory requires a configured integration. A configured webhook/API connection can pass events to focusAlert. This integration is optional.
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.
