## Executive summary

As of November 2026, CybersecTools tracks 167 companies that sell cyber-physical security solutions as their main business. The largest groups are based in the United States, Israel and Germany. In the last 12 months they raised $1.1B across 26 funding rounds, 7 companies were acquired and 15 new companies started in the last two years.

From that field we chose seven solutions that show what is on your industrial networks, find weak spots and spot attacks without stopping production. Claroty Platform suits plants and hospitals that want asset inventory, exposure management, segmentation, threat detection and secure remote access in one platform. Nozomi Networks Platform fits companies with many sites, because sensors and a cloud console show factory and utility networks in one view. Dragos Platform suits teams that want deep knowledge of industrial protocols and clear advice on which flaws to fix first.

The main choice is between an OT specialist and an OT add-on to a platform you already run. Claroty, Nozomi, Dragos and TXOne focus on industrial networks. Armis, Darktrace and CrowdStrike add OT coverage to wider security platforms.

Ask each vendor how it finds devices without disturbing controllers, because active scans can upset fragile equipment.

## How we evaluated

We looked at 287 cyber-physical security solutions from 183 companies, and the 7 on this page made the cut. We combined our judgment from years of leading enterprise security programs with market data from [Mandos](https://mandos.io/data/companies?utm_source=cybersectools.com&utm_medium=shortlist), our market intelligence platform, and with the vendor and review pages listed under Sources at the end of this page. For customer feedback, we left out paid reviews, reviews by vendor staff or partners, review campaigns and anything older than two years, so you get an accurate view of what customers say.

Four traits mattered most: passive discovery of industrial assets; threat detection that understands industrial protocols; vulnerability and exposure management for devices you cannot patch; and fit with your firewalls, SIEM and IT products. We left out firmware, automotive, maritime and medical-device-only products. The order follows how widely each product is used by teams like yours. Company momentum shows how the vendor itself is growing, so a market leader can rank first with a lower score.

## What is Cyber-Physical Security

Operational technology (OT) security products protect the systems that run plants, utilities, hospitals and buildings, such as PLCs, SCADA servers and engineering workstations. Most watch industrial network traffic passively to build an asset inventory, find vulnerabilities and spot unusual commands. Some also segment networks, control remote access by vendors and protect endpoints that cannot be patched.

This matters because an attack on OT can stop production, damage equipment or put people at risk. Many industrial devices are old, cannot run normal security agents and must not be disturbed. OT security gives you visibility and protection that fits those limits, so you can find problems before they stop a line.

#### Our take

Claroty Platform (xDome) finds OT, IoT, medical and IT assets through passive monitoring, safe active queries and engineering project files. It identifies devices and their vulnerabilities, prioritizes exposures, segments networks, detects threats and controls secure remote access. It connects to Microsoft Sentinel, Microsoft Defender, Palo Alto NG Firewall, Fortinet FortiGate, Cisco ISE, QRadar, Google SecOps and AWS Security Hub.

It earns its place by covering the whole job in one platform, from inventory and exposure ranking to segmentation and threat detection, and it reaches past the plant to medical and building devices. Reading engineering project files adds device detail beyond what network traffic shows. It fits mid-market and enterprise sites, so decide which modules you need first rather than buying the full set.

#### Claroty Platform main features

- Asset inventory and discovery across OT, IoT, IoMT, and IT environments

#### What customers say

Sentiment: 79% positive · 21% mixed · 0% negative (from first-hand public reviews and comments, 2024 to 2026).
Most praised: Asset discovery, Integrations.
Most criticized: Setup, Reports.

Claroty's strength is showing what sits on an OT or medical device network, and customers in plants and hospitals rely on it to find and track those devices. Its secure remote access also wins praise, because staff and outside vendors get governed access without old-style VPNs, and customers say the vendor's team stays engaged long after launch. The catch is the start, since initial setup and tuning take planning and real effort in complex sites.

#### Before you buy

Where it is strong:

- Finds devices teams did not know about
- Secure remote access for vendors
- Wide set of firewall and SIEM connections

Ask in the demo:

- Price the modules and hardware for each site
- Plan time for tuning in complex sites
- Ask which discovery methods are safe for your controllers

### 2. Nozomi Networks Platform

**[Nozomi Networks](https://mandos.io/data/companies/nozomi-networks?utm_source=cybersectools.com&utm_medium=shortlist-md&utm_campaign=explore-in-mandos)**. OT/IoT/IT asset discovery & threat detection platform for cyber-physical systems

#### At a glance

- Vendor: Nozomi Networks
- Headquarters: San Francisco, United States
- Founded: 2013
- Deployment: Hybrid
- Company size: Mid-Market, Enterprise
- NIST CSF: Identify, Detect
- Starting price: Contact sales

#### Our take

Nozomi Networks Platform builds an inventory of OT and IoT assets, shows wired and wireless networks, manages vulnerabilities and detects anomalies and threats. It scores risk by asset, zone, site and company and offers response playbooks. It includes endpoint and low-resource remote sensors, executive dashboards, audit-ready reports and the Vantage IQ AI assistant. It connects to Splunk, IBM QRadar, ServiceNow, Google Chronicle, SentinelOne, Cisco ISE, Tanium and Aruba ClearPass.

It earns a place for multi-site estates, because risk rolls up from each asset to zone, site and company, which gives you one ranking across many plants. It runs as a hybrid deployment for mid-market and enterprise. Mitsubishi Electric bought Nozomi in 2025, so ask how it stays neutral across other industrial vendors' equipment.

#### Nozomi Networks Platform main features

- OT and IoT asset inventory
- Wired and wireless network visibility
- Vulnerability management
- Anomaly detection
- OT and IoT threat intelligence
- Response playbooks and workflows

#### Nozomi Networks Platform main integrations

Splunk, IBM QRadar, ServiceNow, Google Chronicle, Microsoft Defender for Endpoint, CrowdStrike Falcon, SentinelOne, Palo Alto Networks Cortex XDR, Cisco ISE, Fortinet FortiGate / FortiSIEM / FortiNAC, Amazon Web Services (AWS), Microsoft Active Directory, Microsoft Endpoint Configuration Manager, Tanium, NetWitness, Aruba ClearPass, Trend Micro Vision One, Rapid7 InsightIDR, Sophos Fusion, Cisco Secure Endpoint, Secureworks Taegis XDR, Barracuda CloudGen Firewall, Carbon Black Defense, Trellix EDR, FortiEDR

#### What customers say

Nozomi's main draw is that it shows OT networks teams could not see before, from legacy shop-floor devices to whole remote sites, and it keeps adding new assets and alerts on its own as traffic flows. Owners find the sensors and cloud console easy to move around in, and they say the support team stays engaged and answers clearly. That said, the rollout leans on your own network, because it has to be well structured before the sensors can see all the traffic.

#### Before you buy

Where it is strong:

- Passive discovery that finds devices fast
- Risk scores from asset to whole company
- Easy sensors and cloud console

Ask in the demo:

- Plan staff time for the rollout
- Ask about documentation for your use cases
- Check sensor options for remote sites

### 3. Dragos Platform Asset Visibility

It connects to Microsoft Sentinel, Splunk, IBM QRadar, ServiceNow, Fortinet FortiGate, Cisco Secure Firewall, Recorded Future and ThreatConnect.

It earns its place on depth, because it reads more than 600 industrial protocols and sorts flaws into fix now, next or never, which matters when most devices cannot be patched quickly. It runs on premises for mid-market and enterprise sites, which suits plants that keep OT data local. Accenture bought Dragos in 2026, so ask how support and pricing work under the new owner.

#### Dragos Platform Asset Visibility main features

- Automated passive-first asset discovery and classification
- Real-time asset inventory with continuous updates
- Deep packet inspection of 600+ industrial protocols
- Targeted active collection via Dragos Agent
- OT-specific vulnerability management with CVSS scoring
- Now, Next, Never vulnerability prioritization framework

#### Our take

Armis Centrix finds and monitors IT, OT, IoT and medical devices without agents and shows their risks in real time. Its modules cover asset management, OT and IoT security, medical devices, vulnerability prioritization (VIPR) and early warning of threats. It connects to Microsoft Sentinel, Microsoft Defender for Endpoint, Entra ID, ServiceNow, IBM QRadar, Jira, Cisco ISE and Google Security Operations SOAR.

It earns a place when you want OT risk in the same program as IT, because one cloud platform covers every device type and ranks flaws across them. That suits mid-market and enterprise teams running an exposure management program. ServiceNow acquired Armis in 2025, so if you run ServiceNow, ask what the tie-in adds, and if you do not, ask what changes for you.

#### Armis Centrix™ main features

Taipei, Taiwan · Founded 2019 · $145M raised · Momentum 61/100 (Mandos)

Certifications: ISO 27001

**Best for:** Plants needing to protect old, unpatched machines

Product page: https://cybersectools.com/tools/txone-ot-security

#### At a glance

- Vendor: TXOne Networks
- Headquarters: Taipei, Taiwan
- Founded: 2019
- Deployment: Hybrid
- Company size: Mid-Market, Enterprise
- NIST CSF: Protect, Detect
- Pricing: Contact sales

#### Our take

TXOne OT Security Platform protects industrial assets with network, endpoint and inspection products built on an OT zero trust approach. Its network defense understands more than 180 industrial protocols and can segment and shield legacy machines. Endpoint protection runs on Windows 2000 through Windows 11, and portable inspection checks devices and media before they enter air-gapped sites. It connects to Splunk, Microsoft Sentinel, IBM QRadar, ServiceNow and Jira.

It earns its place on protection, not only visibility, because it can shield old machines that will never get a patch and check media before it reaches the plant. Hardware bypass keeps production running if a TXOne device fails, which matters on lines that cannot stop. It fits mid-market and enterprise plants, but ask how it shares inventory with any OT monitoring product you already run.

#### TXOne OT Security Platform main features

- Network security with awareness of 180+ industrial protocols
- Network topology and asset mapping
- Endpoint protection for Windows 2000 through Windows 11
- Automated endpoint behavioral baselines
- Inspection of devices and media before they enter the environment
- Air-gap ready security inspection
- Centralized asset visibility across sites
- Automated asset discovery and risk scoring

#### TXOne OT Security Platform main integrations

Splunk, Microsoft Sentinel, IBM QRadar, ServiceNow, Jira

#### Before you buy

Where it is strong:

- Protects very old Windows machines
- Inspects devices before they enter the plant
- Network shielding for unpatched equipment

Ask in the demo:

- Ask which products cover your sites
- Test endpoint protection on your oldest machines
- Check central management across sites

### 6. Darktrace OT

Certifications: SOC 2, ISO 27001, FedRAMP, PCI DSS, HIPAA, Cyber Essentials

**Best for:** Teams wanting AI to learn normal plant behavior

Product page: https://cybersectools.com/tools/darktrace-ot

#### At a glance

- Vendor: Darktrace
- Headquarters: Cambridge, United Kingdom
- Founded: 2013
- Deployment: Hybrid
- Company size: Mid-Market, Enterprise
- NIST CSF: Identify, Detect, Respond
- Pricing: Contact sales

#### Our take

Darktrace OT learns what normal looks like across OT and IT with its Self-Learning AI, then flags insider threats and new attacks without relying on signatures. It keeps an asset inventory across all Purdue Model levels using passive and active scanning, maps attack paths and checks CVE and end-of-life status. It connects to Microsoft Sentinel, Splunk, IBM QRadar, ServiceNow, Cortex XSOAR, Fortinet FortiGate, Check Point NGFW and Cisco ASA.

Its place on the list comes from response, because Cyber AI Analyst investigates and ranks incidents and response actions can run on their own, which helps when no one watches the plant network full time. It runs as a hybrid deployment for mid-market and enterprise. Decide early which actions it may take without a human, since an automatic block on a control network can stop production.

#### Darktrace OT main features

- Continuous OT and IT asset inventory with passive and active scanning
- Real-time monitoring of industrial protocols and IT infrastructure
- Self-Learning AI-based threat detection for zero-day and insider threats
- Cyber AI Analyst for automated incident investigation and prioritization

- Attack path mapping and prioritization
- CVE and End-of-Life status identification

#### Darktrace OT main integrations

Microsoft Sentinel, Splunk, IBM QRadar, Elastic Security, LogRhythm, Rapid7 InsightIDR, ServiceNow ITSM, ServiceNow SecOps, Jira, Microsoft Teams, Slack, Cortex XSOAR, Splunk SOAR, FortiSOAR, Palo Alto Networks NGFW, Fortinet FortiGate, Check Point NGFW, Cisco ASA, Cisco Firepower Threat Defense, Cisco Meraki Firewall, Juniper SRX, Tenable Vulnerability Management, Rapid7 InsightVM, Xage Zero Trust Access, Tines

#### What customers say

Sentiment: 60% positive · 10% mixed · 30% negative (from first-hand public reviews and comments, 2024 to 2026).
Most praised: Asset discovery.
Most criticized: Missing features, False positives.

Darktrace / OT gives teams a view into industrial networks that usually run in the dark, showing which devices are there and what they talk to. It learns what normal traffic looks like for each device and flags anything that strays from it, which reviewers say makes unusual activity easier to spot and investigate.

#### Before you buy

Where it is strong:

- Learns normal behavior to flag odd activity
- Fast setup with vendor help
- Automated incident investigation

Ask in the demo:

- Plan who will tune alerts over time
- Test how easily you can find a given alert
- Decide which response actions may run on their own

#### Our take

CrowdStrike Falcon for XIoT gives visibility and protection for IoT, OT and industrial devices where normal endpoint agents cannot run. It is part of the CrowdStrike Falcon platform, so OT findings sit next to endpoint data, and it is designed to deploy without downtime for devices that cannot be stopped for updates.

It earns a place if you already run Falcon, because you add industrial coverage without a new console. It is cloud-delivered for mid-market and enterprise. Its listed integrations are two OT specialists on this list, so ask how much device discovery comes from Falcon itself and how much from a partner product you would also need.

#### CrowdStrike Falcon for XIoT main features

- Visibility for XIoT assets
- Protection for mission-critical XIoT devices
- Integration with Falcon platform
- Support for IoT and OT environments
- No-downtime deployment

## How they fit your cybersecurity program (NIST CSF)

NIST CSF 2.0 has six functions: Govern, Identify, Protect, Detect, Respond and Recover. The grid shows which functions each pick maps to in our record, so you can see where a solution sits in your program and what it leaves to other controls.

All 7 solutions map to Detect. 6 of 7 map to Identify. 3 of 7 map to Protect. 1 of 7 maps to Respond. None map to Govern or Recover.

| Solution | Govern | Identify | Protect | Detect | Respond | Recover |
| --- | --- | --- | --- | --- | --- | --- |
| All solutions on this list | 0 of 7 | 6 of 7 | 3 of 7 | 7 of 7 | 1 of 7 | 0 of 7 |

Each cell shows how many of the function's NIST CSF 2.0 categories the solution maps to, with the category names.

A product helps you reach these outcomes, but it does not make you compliant on its own. Your people and processes do the rest.

## CISO checklist for selecting a Cyber-Physical Security product

Work through these steps in order to go from unknown industrial networks to a contract you can defend.

1. **List your sites and the main control systems at each.** Coverage and sensor count depend on it.
2. **Agree with operations on what may touch the network.** Safety and uptime come first in OT.
3. **Start with passive discovery at one site.** It shows real assets without risk.
4. **Check support for your controllers and protocols.** Coverage differs by vendor and industry.
5. **Ask how vulnerabilities are prioritized for devices you cannot patch.** You need a short list, not a long one.
6. **Plan secure remote access for vendors.** Shared remote access is a common way in.
7. **Confirm how alerts reach your SOC or SIEM.** Someone must act on what the product finds.
8. **Decide who will tune alerts over time.** Noise is a common complaint.
9. **Price sensors, licenses and support for five years.** Hardware and modules add up across sites.

Start with how much OT you run and who will operate the product. If you want one platform for plants or hospitals, Claroty covers inventory, exposure, segmentation and remote access. Nozomi Networks suits companies with many sites, and Dragos suits teams that want deep protocol knowledge.

TXOne helps plants protect old, unpatched machines. Armis, Darktrace and CrowdStrike add OT coverage to wider platforms you may already use.

## Frequently Asked Questions

### What is the difference between IT and OT security?

IT security protects data and office systems. OT security protects machines and the systems that control them, where safety and uptime come first and devices often cannot be patched.

### Is passive monitoring safe for industrial networks?

Passive monitoring only listens to traffic, so it does not touch devices. Active queries can give more detail but should be tested, because some old controllers react badly.

### Do I need a separate OT product if I have an IT security platform?

It depends on how much OT you run. OT specialists understand many more industrial protocols. OT modules of wider platforms can be enough for lighter needs.

### How do I protect devices that cannot be patched?

Segment them, watch their traffic and control who can reach them. Some products here also shield old machines on the network or harden their endpoints.

### How should vendors and contractors connect to OT?

Use secure remote access with approval, recording and time limits instead of shared VPNs. Several products here include it.
