Top OT Security Companies in 2026

Among OT security companies, there is a meaningful split between OT-native platforms and enterprise security vendors that have extended into operational technology. 

Dragos, Nozomi Networks, and Claroty are the clearest OT-native OT security vendors here. Their platforms are purpose-built for industrial visibility, threat detection, and OT monitoring across complex cyber-physical environments.

Fortinet and Palo Alto Networks are strong OT security vendors when network segmentation, industrial zoning, policy enforcement, and convergence with broader network security programs matter most. 

CrowdStrike is stronger when the organization wants unified IT and XIoT visibility under a cloud-native platform. Forcepoint belongs more in the “critical infrastructure security and secure connectivity” bucket than in the pure-play OT monitoring tool bucket. This is an important distinction for organizations that need deep passive asset discovery.

Network Intelligence is slightly different from the product-led players. Its OT security solutions combine consulting, SOC for OT, maturity assessments, and critical infrastructure security services. 

This makes it more relevant for organizations that want execution support and outcome ownership, rather than just another internal tool.

How We Compiled This List 

Researched real operator problems for operational technology

Before evaluating any OT cybersecurity solutions, we anchored the research in the problems teams are actually trying to solve:

• Lack of visibility across ICS, SCADA, and legacy assets
• Difficulty deploying OT monitoring tools without disrupting operations
• Weak segmentation between IT and OT environments
• Unmanaged remote access to critical infrastructure
• Alert fatigue from tools that may be lacking in an industrial context

To validate this, we reviewed community sentiment and practitioner commentary on third-party platforms to understand the field feedback from engineers comparing different OT security tools.

Verified every vendor against primary sources and peer review platforms

Every vendor included in this list was evaluated across three layers:

1. Official product capabilities: Vendor OT-specific product pages where available, as well as the protocol support and claims around OT monitoring, asset discovery, and threat detection.
2. Independent review platforms: We examined verified user reviews from G2, Gartner Peer Insights, and Capterra to look for:

• Consistent praise patterns like visibility, ease of deployment, and support quality
• Recurring complaints like cost, complexity, false positives, and tuning effort
• Trade-offs that may not appear in vendor documentation

Evaluated tools based on operational realities

Each OT cybersecurity solution was vetted based on how it performs across the realities that matter, such as:

• If it can be deployed passively without disrupting industrial processes
• If it accurately discovers and classifies OT devices and protocols
• Whether the OT solutions’ monitoring provides actionable signals
• How well it fits into existing SOC and IT security workflows
• Whether it can handle distributed industrial environments across sites
• Whether plant teams and security teams can both work with it

• On the network side, Palo Alto firewalls (which enable OT segmentation and policy enforcement) range widely depending on model and throughput, with entry enterprise appliances starting in the $5,000–$10,000+ range, and large-scale deployments costing significantly more

8. Forcepoint

Forcepoint security for OT devices (Source: Forcepoint)

Forcepoint is the most unusual inclusion in this list because it is not a leading OT-native platform in the same sense as Dragos or Nozomi. 

Its value lies more in critical infrastructure connectivity, NGFW, secure remote access, deep packet inspection, and network/data protection in high-consequence environments.

Key features 

• Combines human behavior analytics with real-time monitoring to detect and prevent threats in OT and ICS environments based on user activity
• Uses Forcepoint NGFW with consistent policy enforcement to secure OT networks across physical, virtual, and cloud environments while inspecting encrypted traffic
• Enables secure data movement with Forcepoint Data Guard, validating commands and data flows at the application layer to protect sensitive OT operations
• Supports segmented and one-way data transfer architectures for critical infrastructure, helping meet compliance standards such as NERC-CIP and IEC 62443
• Integrates Human Point System capabilities (DLP, CASB, insider threat protection) to secure data, users, and access across IT and OT environments

Pros 

• Runs efficiently in the background while still allowing quick access to diagnostics when needed
• Provides centralized visibility with easy export options (CSV and graphical views), making it simple to analyze and report on data
• Offers unified web and data protection across on-premise and remote users through a single management console

Cons

• Interface can feel less interactive in certain areas, impacting usability for some workflows
• May experience minor performance issues depending on deployment conditions
• Advanced data searches can sometimes be slow, particularly when querying historical data

Best for

Critical infrastructure operators that need secure connectivity, NGFW, segmentation, and data/control protection for OT-adjacent environments, rather than a pure OT monitoring platform.

Pricing

Forcepoint does not offer public standalone OT pricing as costs are modular and quote-based. 

But we found public pricing in a Forcepoint 2022 price catalogue hosted online and in live reseller listings. 

In that catalogue:

• Forcepoint Data Guard hardware is listed at $9,905 for a small 1U R640 appliance and $15,630 for a medium 1U R640 appliance
• The Data Guard Unstructured Data Bundle is listed at $98,700, and the developer license at $49,140. 
• The same catalogue also says Essential Support is 15% of the list price, with Enhanced Support carrying a $12,500 minimum per customer per year and Enterprise Support a $75,000 minimum per customer per year. 

The document labels these as suggested end-user prices, with the reseller applying discounts.

For adjacent Forcepoint products, reseller pricing on Insight shows that implementation and support can add meaningful cost on top of licensing. 

For example, Insight lists a Forcepoint implementation service at $1,519.99 list price, a DLP Discover implementation package at $12,504.99 list price, and a Forcepoint Essential Support renewal item at $20,315.99 list price. 

*These are not OT bundle prices, but they are useful as real-world pricing anchors for how Forcepoint costs can expand once services and support are included.

Picking the Best OT Security Solution for Your Organization

The most useful way to evaluate OT security tools is to decide what kind of OT problem you are actually solving.

If the security to-do list for the organization is based solely on OT-native depth, Dragos, Nozomi Networks, and Claroty still feel like the clearest leaders among OT security companies. 

If the focus is on broader enterprise fit, segmentation, remote access, and stack alignment, Fortinet and Palo Alto Networks are good options to explore. 

If the main goal is service-led operational ownership to protect all operational technology equipment across the organization, Network Intelligence can fill that need. 

And if the organization wants unified IT and operational visibility, CrowdStrike is the more natural crossover pick. 

Forcepoint can work, but mostly when the requirement is secure critical-infrastructure connectivity rather than best-in-class passive OT monitoring.
