octoplant Alternatives: The Automation Change Management Market, Compared
octoplant vs Claroty, Nozomi and Network OT Security: Complement, Not Substitute
octoplant vs Claroty, Nozomi, Armis and Dragos: what a network OT security platform sees, what octoplant sees, where they overlap and how to combine them.
Searching octoplant vs Claroty usually means a security team that already owns a network monitoring platform and wants to know if it also covers backup and change management. The short answer is no. Claroty, Nozomi Networks, Armis, Dragos and Tenable OT see the plant from the network: which devices exist, what they say to each other, which carry known vulnerabilities, and whether traffic looks like an attack. octoplant sees inside the device: the logic, configuration and firmware, compared with the approved version and ready to restore. They complement each other. This page sets out what each sees, where they overlap, how the market consolidated in 2026, and how to combine them. Facts are public and dated as of October 2026.

octoplant vs Claroty and Nozomi: what each side sees
The network platforms. Claroty describes several discovery methods: passive monitoring, safe queries, project file analysis, ecosystem enrichment and an edge collector (claroty.com). Nozomi pairs network sensors (Guardian), wireless sensing (Guardian Air) and an endpoint sensor (Arc) with its Vantage platform (nozominetworks.com). Dragos centres on threat detection, intelligence and incident response. Armis covers asset intelligence across IT, OT and IoT. Tenable OT uses active querying of PLCs. Gartner’s 2026 Magic Quadrant for CPS Protection Platforms names Nozomi, Claroty, Armis and Dragos as Leaders (Claroty).
octoplant and octovision. octoplant uploads from devices on a schedule, versions what it finds and compares it with the approved version (amdt.com). octovision turns that data into multi-site inventory, CVE matching and lifecycle status, “without network scanning or agents” (amdt.com).
| Question | octoplant and octovision | Network OT security (Claroty, Nozomi, Armis, Dragos) |
|---|---|---|
| How it finds assets | From project and configuration data held in octoplant | Network traffic, safe or active queries, integrations |
| What it knows about a PLC | Logic, configuration, firmware and software versions, change history | Identity, firmware where visible, communications, risk |
| Program content | Versioned and comparable through Smart Compare | Not kept; Claroty can analyse project files |
| Change detection | Scheduled compare of device against approved version | Typically flags program downloads and configuration commands seen on the wire |
| Vulnerabilities | CVE matching from device data, criticality classification | CVE matching from discovered asset data, exposure scoring |
| Threat detection | No | Yes, the core job |
| Recovery | Restore the approved version; Disaster Recovery | No |
| Unnetworked machines | AMDT states coverage of unnetworked and partially networked machines | Not visible without a network path |
| Where it runs | Mainly on-premises | Sensors plus on-premises or cloud console |
This is not hypothetical. In the 2023 Unitronics campaign, the CISA advisory records that the attackers erased the original ladder logic, loaded their own and reset the software version so that operators could not connect from their engineering workstations. Spotting the intrusion was one problem; getting the right program back onto each device was another, and only a stored, known-good copy answers it.
An illustrative incident. At 02:10 the network platform raises an alert: an unfamiliar engineering workstation has sent a program download to a filler controller. That tells the team what happened and where. It does not tell them which rungs changed or what the last good program was. A scheduled octoplant compare shows the difference against the approved version, and a restore puts it back once the workstation is isolated. Each tool did the job it was built for.
octoplant vs Claroty: where they overlap
Inventory. Both produce a list of assets with vendor, model and firmware. The network list includes anything that talks on the wire; the octoplant list includes everything octoplant manages, including some machines with no permanent network path. Since the octovision Summer Release 2026, octovision imports CSV exports from discovery tools and reports a managed versus unmanaged coverage figure (octoplant.com). That figure is where the two inventories meet usefully: devices the network sees that octoplant does not yet back up. See octovision Asset Inventory.
Vulnerabilities. Both match assets to CVEs. octovision works from firmware and software versions read out of device data, with criticality classification and false-positive management. Network platforms work from what they discover and add exposure context from the network. Plants should pick one as the system of record for CVE status, or the backlog will be counted twice.
Configuration depth. The boundary is moving. Claroty lists project file analysis among its discovery methods, Tenable OT offers PLC configuration snapshots, and Claroty enriches Rockwell’s AssetCentre with vulnerability and threat data (Claroty). Dragos is moving the same way from another direction: NetRise, part of the Accenture transaction, adds firmware and software supply-chain analysis. None of these, on public information, keeps a restorable, versioned program across vendors. That remains octoplant’s ground. See octoplant vs FactoryTalk AssetCentre for the Rockwell variant.
The 2026 consolidation
The network OT security market changed owners at speed in 2026:
| Date | Event | Source |
|---|---|---|
| January 2026 | Claroty raises a $150,000,000 Series F, at about a $3 billion valuation | SecurityWeek |
| 28 January 2026 | Mitsubishi Electric completes its acquisition of Nozomi Networks, about $1 billion | SecurityBrief |
| 20 April 2026 | ServiceNow completes its $7.75 billion acquisition of Armis | ServiceNow |
| June 2026 | Accenture announces a majority stake in Dragos, with runZero and NetRise, about $4.175 billion | Pulse2 |
What it means for a plant. Network visibility is becoming part of larger groups: an automation OEM (Mitsubishi Electric), an IT workflow platform (ServiceNow) and a services firm (Accenture). Expect tighter ties to those owners’ ecosystems, and ask each vendor how its roadmap and neutrality will hold. For the ServiceNow side, where OT asset data increasingly lands, see ServiceNow and ITSM.
How to combine them
- Use network discovery as the census. Import its export into octovision and work down the unmanaged list until every critical device has a backup job.
- Name a system of record per fact. Existence and communications from the network platform; logic, configuration and firmware version from octoplant.
- Link the alerts in the runbook. A download alert from the network platform should trigger an octoplant compare of that device.
- Write the recovery sequence. Isolate with the network and security tools, then restore from octoplant; see Disaster Recovery.
- Plan for files, not APIs. With no public integration, the link today is CSV import and the export APIs; detail on OT Security Platforms.
Questions to put to both vendors before buying either:
- Which of our assets does your inventory see, and which does it miss? Ask for the list from a pilot, not an estimate.
- How do you identify firmware: from traffic, from a query, or from the device’s own project data?
- What does your product send off site, including to AI features?
- Which export formats and APIs exist today, and has anyone connected your product to the other one?
- Who on our side would own the joint process, and what training does that person need?
Where it gets hard
Two inventories will disagree. Naming, firmware strings and site codes differ. Budget time to reconcile them, and decide which wins.
Ownership splits. The network platform usually belongs to OT security, octoplant to controls engineering. Without one owner of the joint process, alerts fall between teams.
Both touch controllers. Active queries and scheduled uploads each add load and access. Schedule them deliberately and agree the credentials with whoever owns the network; an OT network assessment is a sensible starting point.
Integration is manual today. We found no public integration between octoplant and Claroty, Nozomi, Dragos or Armis. Ask both vendors what is shipping, not what is planned.

Frequently asked questions
Does Claroty do the same thing as octoplant?
No. Claroty builds an OT asset inventory through passive monitoring, safe queries, project file analysis and integrations, then adds exposure management, threat detection and secure access. octoplant keeps versioned, restorable copies of what is inside each device and compares them with the approved version. They overlap on inventory and vulnerabilities, not on backup and recovery.
Is octovision a replacement for Nozomi or Claroty?
No. octovision builds its inventory and CVE matching from octoplant's project and configuration data, "without network scanning or agents". It does not watch network traffic or detect attacks. It can import CSV exports from discovery tools and report which assets are managed by octoplant and which are not, which makes it a complement to network monitoring.
Does octoplant integrate with Claroty, Nozomi, Dragos or Armis?
As of October 2026 we found no public integration between octoplant and Claroty, Nozomi, Dragos or Armis. octovision imports CSV files from discovery tools, and octoplant and octovision offer export APIs for CMDB and ticketing systems. Ask AMDT and your security vendor directly whether a private or planned integration exists.
Do we need both a network OT security platform and octoplant?
Most plants with real recovery and security obligations will. The network platform tells you which devices exist, what they talk to and whether something looks like an attack. octoplant tells you what logic and configuration each device holds, whether it changed, and lets you put the approved version back. One detects; the other recovers.
Who owns Nozomi Networks, Armis and Dragos now?
As of October 2026, Mitsubishi Electric completed its acquisition of Nozomi Networks on 28 January 2026, and ServiceNow completed its $7.75 billion acquisition of Armis on 20 April 2026. Accenture announced a majority stake in Dragos, with runZero and NetRise, in June 2026. Claroty remains independent after a $150 million Series F in January 2026.
