The OT asset inventory your
production floor has never had.
No hardware sensors. No agents. Deployed on-premise and fully under your control. OTbase automatically discovers every device across your facilities — controllers, sensors, switches, every networked asset on the production floor — and keeps the inventory current, every 24 hours.
One inventory.
Every facility. Every device.
Most multi-site manufacturers run their OT documentation across disconnected spreadsheets, local maintenance records, and institutional memory. Each facility has its own version of the truth. None of them match.
OTbase replaces all of it with a single, automatically updated inventory — built from what is actually running on your network, not what someone last entered manually. Every device at every site, in one place, with the context your IT, operations, and engineering teams each need to do their job.
When a new facility comes into your network — whether through organic growth or acquisition — OTbase discovers its OT environment the same way it discovered the first one. The inventory expands automatically. No manual onboarding project. No site-by-site spreadsheet effort.
What goes into a complete OT asset inventory
A useful OT asset inventory is not a list of IP addresses. It is a detailed, contextualised record of every device on every network across every site — updated automatically so it reflects what is actually there today, not what someone documented two years ago.
Every device identified by name, vendor, model, serial number, firmware version, and device type
Location and network context — which facility, which segment, what it connects to
Product lifecycle status — whether a device is current, end-of-life, or already discontinued
Known CVEs mapped to the specific devices in your environment, without running a vulnerability scan
Network topology diagrams generated automatically from discovery data — including field bus and L1 networks
Configuration and change history so deviations from the known baseline are immediately visible
All of this without placing a single hardware sensor on the network and without any disruption to production.
The OT visibility gap is not a technology problem.
It is a documentation problem.
Most manufacturing facilities have capable engineers and functional equipment. What they do not have is a systematic, automatic process for documenting what is running, where it sits in the network, and when it last changed.
That documentation gap is not unique to any one company or industry. It is the standard state of OT environments that were built to run production, not to be inventoried. OTbase does not change how your floor operates. It builds the documentation layer on top of what is already there — passively, continuously, and without interfering with a single running process.
Built for the way multi-site manufacturing actually operates
OT environments in manufacturing are not uniform. Different facilities run different equipment from different vendors installed at different times. Some sites were built from scratch. Some were acquired. Some have documentation. Most do not.
OTbase works across all of it. The Discovery software runs locally at each site, crawls the OT network using both IT and OT protocols — and sends every asset detail back to a central OTbase Inventory instance.
OT protocols supported out of the box:
"OTbase is used by multi-site industrial manufacturers to manage OT asset inventories across dozens of facilities globally. The same inventory discipline that exists for IT — applied to the production floor."
Here's how it's done:
Discover technical asset details automatically
OTbase Discovery software runs at each site and automatically identifies every device on the OT network — by vendor, model, firmware, serial number, OS version, and installed software. No hardware sensors. No agents on devices. No disruption to running processes.
Learn how discovery works →Consolidate asset data and metadata
All asset data from every site flows into a single OTbase Inventory. Add context — geolocation, ISA 95 system hierarchy, network groupings, custom fields. Map physical process dependencies. Know not just what you have, but where it sits and what depends on it.
See the inventory in action →Work with your OT asset inventory
Run vulnerability assessments against your exact installed base. Generate compliance reports in hours instead of months. Feed Power BI dashboards that keep management current without manual updates. Create the documentation layer your production floor has always needed — without changing how it operates.
