OT Security Platforms – Nozomi Networks vs. Claroty: Which One Leads the ICS Cybersecurity Front?
Operational Technology (OT) security has quickly become one of the most discussed trends in cyber defense. With the surge in cyberattacks targeting industrial infrastructure, companies are under pressure to guard their control systems like never before. Two names consistently topping Google Trends in this segment are Nozomi Networks and Claroty. Businesses are increasingly comparing these OT security giants to understand which platform best shields critical infrastructure.
So, what’s making these two companies stir the pot right now? Let’s dive deep into this highly competitive space, pitting Nozomi Networks and Claroty head to head.
OT Security: Why It’s More Critical Than Ever
OT systems are what keep the lights on, water running, transportation smooth, and factories moving. Unlike traditional IT, which deals with data, OT commands the physical world—water pumps, valves, energy meters, and manufacturing robots.
As more OT systems connect to IT networks and the internet—often referred to as Industrial Internet of Things (IIoT)—they become more vulnerable. According to recent data from IBM’s X-Force Threat Intelligence Index, attacks on industrial sectors rose by 50% year-over-year in 2023. This is precisely why platforms like Nozomi Networks and Claroty are gaining traction.
Who Are Nozomi Networks and Claroty?
Nozomi Networks, headquartered in California, specializes in OT and IoT security. They’ve built a solid reputation with their Vantage platform, which offers comprehensive network visibility and real-time threat detection for critical infrastructure.
Claroty, based in New York, also delivers deep security capabilities for OT, IoT, and even Medical IoT (MIoT) through its flagship platform, xDome. They’re backed by major cybersecurity firms like Palo Alto Networks and SoftBank, and have a strong focus on heavily regulated industries like healthcare, manufacturing, and energy.
Both companies offer robust platforms. But their focus, architecture, threat intelligence, and market approach differ in meaningful ways.
Nozomi Networks: Strength in Passive Monitoring and Scalability
One of Nozomi’s core advantages is its use of passive deep-packet inspection techniques. This means they can discover and monitor OT systems without disrupting them—critical for sensitive industrial environments.
Main features of Nozomi’s Vantage platform:
- Deep Network Visibility: Real-time and historical visibility across OT, IoT, and IT assets.
- AI-Powered Threat Detection: Unique machine learning models trained specifically on industrial behavior patterns.
- Cloud-Delivered: Vantage is deployed on AWS and scales effortlessly across multiple facilities.
- Asset Inventory and Mapping: Automatically discovers devices and relationships between them.
- Third-Party Integration: Offers native plugins for platforms like Splunk, ServiceNow, and IBM QRadar.
What stands out is Nozomi’s momentum in smart manufacturing and energy sectors. Their platform is used by dozens of Fortune 500 companies.
Claroty: Expanding the Boundaries of OT Security
Claroty offers a broader approach by extending OT security to include Industrial IoT, Enterprise IT, and even connected medical devices. Its integration capabilities are more IT-native, making it an attractive choice for large enterprises already using IT security tools.
Key features of Claroty’s xDome platform:
- Unified Visibility: Covers OT, IoT, and MIoT in one single pane-of-glass platform.
- Threat Detection: Behavioral and signature-based threat detection enhances anomaly analysis.
- Remote Access Management: Audit and control third-party vendor access to OT systems, a critical compliance point.
- Risk Scoring: Assesses asset-by-asset vulnerabilities based on real-world exploit information.
- Zero Trust Capabilities: Incorporates network segmentation and access control down to the device-level.
Claroty has carved a niche with energy utilities and hospital systems, where protecting legacy equipment is paramount. Their support for medical device protocols and regulatory alignment (e.g., HIPAA compliance) gives them an edge here.
Comparing Head-to-Head: A Feature Matrix
Here’s a quick look at how both platforms compare across key OT security functions:
| Feature | Nozomi Networks | Claroty |
|---|---|---|
| Asset Discovery | Passive inspection, auto-mapping | Active & passive discovery, strong MIoT inventory |
| Threat Detection | Machine Learning, Rule-Based | Behavioral, Signature, AI-enhanced |
| Cloud Support | Cloud-native (AWS) | Modular platform, cloud-compatible |
| Compliance Tools | Basic NIST/IEC reports | Extensive (HIPAA, NIST, IEC, ISA guidelines) |
| Resource Usage | Light footprint, scalable | Custom tuning needed for larger deployments |
This table doesn’t just compare features—it reflects different security philosophies. Nozomi streamlines and excels in core industrial processes. Claroty goes big on coverage, from factory floors to radiology labs.
Recent Developments in 2024
Both companies have had a dynamic start to 2024. Let’s look at some updates that affect decision-makers.
Nozomi Networks: Announced deeper automation capabilities in partnership with Microsoft Defender for IoT. Their collaboration with Schneider Electric is enhancing cyber coverage for utility networks worldwide.
Claroty: Raised $100M in a Series E funding round co-led by SoftBank, signaling ambitious expansion. They’ve also launched new integration features with Palo Alto Networks and CrowdStrike—leaping forward in convergence between OT and cloud-native IT security.
The increased funding is expected to drive their R&D, especially in regulated sectors. This shows that Claroty is inching towards becoming an end-to-end platform for enterprise-level IoT security.
Security Operations and Ease of Use
From a usability perspective, Nozomi has a cleaner dashboard, ideal for teams with limited cybersecurity expertise. The learning curve is gentle, and automation reduces manual effort significantly.
Claroty’s interface is designed for large-scale implementation with fine-grained control. While powerful, it requires a bit more cybersecurity know-how, making it better suited for organizations with established SOCs (Security Operation Centers).
To relate this to real life, imagine Nozomi as a smart thermostat—plug it in and forget it. Claroty, however, is more like a custom HVAC system—you’ll need time to configure, but the controls are richer.
Support, Integrations, and Customer Feedback
User feedback on review platforms like Gartner Peer Insights and G2 suggests both platforms score high in reliability and response time. But there are subtle differences.
Support Feedback:
- Nozomi: Known for responsive customer service and quick patch rollouts.
- Claroty: Appreciated for expert consultation and offering best practices during deployment.
When it comes to tool integrations:
- Claroty supports more native integrations with cloud and SaaS security tools.
- Nozomi integrates strong with firewalls and SIEM systems.
Which Platform Should You Choose?
Choice depends on your organizational focus:
- Pick Nozomi if: You’re in manufacturing, utilities, oil & gas, and need “plug-and-play” visibility with automation.
- Choose Claroty if: You manage a hybrid environment with healthcare, IT, and OT assets needing deep compliance controls.
If we were to compare them to cars—Nozomi is the reliable Tesla Model 3. Claroty is the customizable Range Rover. Both are excellent, but suited for different terrains.
Conclusion: Security Doesn’t Rest—Neither Should You
With cyberattacks targeting essential infrastructure almost weekly, enterprises must act quickly. Whether it’s protecting a water treatment plant or securing ventilators in a hospital, both Nozomi and Claroty offer critical shields against rising threats.
Invest the time to assess which platform aligns with your risk profile, team structure, and industry regulations.
If you’re still unsure, reach out to their sales teams, request a demo, and see which one feels more intuitive. You wouldn’t buy a house without walking through it—treat your cybersecurity framework the same way.
