Quick answer: The best AI SOC platform for OT and IoT security in 2026 is Seceon’s Open Threat Management (OTM) platform with aiSecOT360 and SeraAI. It is the only option in this comparison that runs IT and OT detection, SOAR response and an autonomous AI analyst on one engine. It monitors 70+ industrial protocols passively and deploys fully air-gapped. Claroty, Nozomi Networks, Dragos, Armis and Microsoft Defender for IoT are strong OT visibility tools, but each sends its alerts to a separate SIEM and SOAR.

Attackers no longer start in the plant. According to a joint CISA, NSA and FBI advisory, Volt Typhoon actors pre-positioned themselves on IT networks to enable lateral movement to OT assets. In some victim environments they kept access for at least five years (CISA AA24-038A). An attack that crosses from IT into OT is invisible to a team that watches the two worlds in separate tools.

That is why AI SOC platforms are now judged on how well they connect IT, OT, IoT and ICS telemetry, and how safely they automate response around physical processes. This guide compares six platforms for enterprise security leaders and SOC teams.

Disclosure: this guide is published by Seceon. Competitor details come from vendor documentation, public filings and independent sources as of October 2026.

Key takeaways

• Seceon OTM with aiSecOT360 and SeraAI is the best AI SOC platform for OT and IoT security in 2026. It correlates IT and OT events in one aiSIEM engine, so an attacker pivoting from IT into OT is caught at every stage.
• Visibility: aiSecOT360 discovers OT assets passively, with zero agents on PLCs, RTUs, DCS or HMIs, across 70+ industrial protocols including Modbus, DNP3, IEC 61850, OPC-UA, BACnet and PROFINET.
• Automation depth: Seceon’s SeraAI autonomous SOC resolves 70% or more of L1 alerts without an analyst. aiSOAR runs OT-safe response with safety interlocks, so automation never disconnects a critical asset on its own.
• Platform fit: Seceon deploys on-premises or fully air-gapped with data-diode support. Microsoft retired downloads of its legacy on-premises Defender for IoT console on January 1, 2025.
• Market shift: Two OT security leaders changed owners in 2026. Mitsubishi Electric completed its Nozomi Networks acquisition in January, and ServiceNow closed its Armis acquisition in April.

Quick answer: the best AI SOC platforms for OT and IoT security

What Are AI SOC Platforms?

Quick answer: AI SOC platforms use machine learning and AI agents to collect security telemetry, correlate it into incidents, investigate alerts and trigger response with less manual analyst work. Autonomous SOC platforms go further: AI agents triage and resolve routine alerts on their own and escalate only confirmed threats. Seceon’s SeraAI, for example, resolves 70% or more of L1 alerts without analyst intervention.

A traditional security operations center relies on analysts to read alerts, query logs and run playbooks by hand. AI cybersecurity changes the division of labor. Models baseline normal behavior, correlate weak signals into one incident, and explain the attack chain in plain language. SOC automation then contains the threat in seconds rather than hours.

Why OT, IoT and ICS Need a Different Kind of AI SOC

Quick answer: OT and ICS systems control physical processes, so security tools must observe them passively, understand industrial protocols, and never take an automated action that could stop production or create a safety risk. IT-only AI SOC platforms usually lack OT protocol visibility, and OT-only tools usually lack IT correlation and automated response.

Operational technology breaks three assumptions that IT security relies on:

• You cannot install agents everywhere. PLCs, RTUs, DCS controllers and HMIs often cannot run endpoint software, so visibility must come from passive network monitoring through a TAP or SPAN port.
• The protocols are different. Modbus, DNP3, IEC 61850, OPC-UA, BACnet and PROFINET carry commands to physical equipment. A detection engine that cannot parse them cannot tell a normal setpoint change from a malicious one.
• Automated response can do physical harm. Isolating the wrong controller can stop a production line or a substation. Response in OT needs safety interlocks, protected assets and human approval for irreversible actions.

IoT adds scale: building management systems, cameras, medical devices and campus sensors that rarely appear in an IT asset inventory.

How We Evaluated These Platforms: The OT SOC Readiness Model

We scored each platform on three criteria that matter most to enterprise security operations teams protecting OT and IoT.

We also mapped each platform to the OT SOC Readiness Model, a five-level framework Seceon uses to describe how far a SOC can see and act across OT:

Standalone OT security tools typically take a SOC to Level 2 or 3. Reaching Levels 4 and 5 requires IT and OT detection, SOAR and AI investigation on the same platform.

The Best AI SOC Platforms for OT and IoT Security in 2026

1. Seceon OTM with aiSecOT360 and SeraAI: best overall AI SOC platform for OT and IoT

Quick answer: Seceon’s Open Threat Management (OTM) platform is the best AI SOC platform for OT and IoT security because it combines passive OT/IoT visibility (aiSecOT360), IT/OT correlation in one detection engine (aiSIEM), OT-safe automated response (aiSOAR) and an autonomous AI analyst (SeraAI) on a single platform that can run fully air-gapped.

Most OT security products stop at visibility and forward alerts elsewhere. Seceon takes the whole SOC to the plant floor. aiSecOT360 watches industrial networks passively, aiSIEM correlates what it sees with IT, identity and cloud activity, SeraAI investigates, and aiSOAR responds with OT safety built in.

Visibility: every Purdue level, zero agents

• Passive, agentless deployment: aiSecOT360 connects through a network TAP or SPAN port, with zero agents on PLCs, RTUs, DCS or HMIs and no inline interruption risk.
• 70+ industrial protocols: process control (Modbus, DNP3, IEC 61850, OPC-UA, OPC-DA), building automation (BACnet, LonWorks, KNX, DALI), industrial Ethernet (PROFINET, EtherNet/IP, POWERLINK), energy (IEC 60870-5, ICCP, IEEE C37.118) and transport (GSM-R). Custom parsers for proprietary protocols are delivered within 96 hours.
• Purdue Level 0–4 monitoring: per-level anomaly detection and east-west traffic analysis between levels.
• Fast baseline: automated OT asset discovery and behavioral baselining within 7 days.
• IoT beyond the plant: building management systems, campus IoT devices and medical devices in the same inventory as IT.

Automation depth: an autonomous SOC that is safe for OT

• SeraAI autonomous analyst: resolves 70% or more of L1 alerts without analyst intervention and escalates only confirmed true positives with full context.
• Natural language investigation: analysts ask questions such as “Show me all lateral movement in the last 24 hours” across SIEM, NDR, XDR and identity data at once.
• Playbooks in about 30 seconds: SeraAI turns a plain-language description into a production aiSOAR playbook.
• Evidence before action: in SeraAI, one agent argues the case for malicious intent, mapped to MITRE ATT&CK, while a second looks for legitimate explanations such as a maintenance window. Conclusions must tie to retrievable records.
• OT-safe response: aiSOAR applies safety interlocks to automated playbooks. Critical assets can be marked as protected, and irreversible actions require approval from an authorized person.

Detection: the IT-to-OT kill chain in one view

aiSecOT360 shares the aiSIEM engine with IT detection, so OT findings are correlated with IT threats in the same console. An attacker who starts in IT and pivots to OT is caught at every stage, which is exactly the pattern CISA described for Volt Typhoon.

aiSecOT360 also carries ICS-specific threat signatures for TRITON/TRISIS, Industroyer2/CRASHOVERRIDE, Volt Typhoon and Stuxnet-class attack patterns, with custom ICS signature development.

Platform fit: built for critical infrastructure

• Air-gapped by design: a dual-stage collection architecture with a proxy collector and data diode keeps data flow strictly one-way out of the OT zone. Seceon is compatible with unidirectional gateways such as Waterfall and Owl.
• Sovereign AI: SeraAI runs its language model on-premises, with no dependency on overseas AI services.
• Compliance: NERC CIP v7 with automated evidence collection, IEC 62443 security levels per zone and conduit, and NIST SP 800-82.
• Consolidation: OT security, SIEM, SOAR, NDR, UEBA and AI investigation are modules of one platform, not separate products to integrate.

Best fit: Energy and utilities, manufacturing, oil and gas, water, rail, healthcare and government SOCs that need one AI SOC across IT, OT and IoT, including air-gapped sites.

The Alternatives: Where OT Visibility Tools Fall Short as an AI SOC

Quick answer: Claroty, Nozomi Networks, Dragos, Armis and Microsoft Defender for IoT are OT and IoT visibility and detection tools. Each forwards its findings to a separate SIEM and SOAR for IT correlation and response. That keeps most SOCs at Level 3 of the OT SOC Readiness Model, while Seceon’s unified platform reaches Levels 4 and 5.

2. Claroty (xDome and Continuous Threat Detection)

What it is: A cyber-physical systems (CPS) protection platform for asset inventory, exposure management, network protection and threat detection.

Where it falls short as an AI SOC:

• Claroty’s cloud offering (xDome) and on-premises offering (Continuous Threat Detection, CTD) are separate products (Gartner Peer Insights).
• xDome is designed to fit into an existing security stack rather than replace it, sending OT alerts to SIEMs such as Splunk, Microsoft Sentinel and QRadar (Splunkbase). IT/OT correlation and response therefore depend on that SIEM.
• Independent buyer research notes that meaningful rollouts usually require scoped implementation, integration and OT-specific tuning, and that pricing is by custom quote (RFP Wiki).

How Seceon compares: Seceon aiSecOT360 delivers OT visibility, IT/OT correlation and SOAR response in one console, deployable on-premises or air-gapped from a single platform.

3. Nozomi Networks

What it is: An OT, IoT and cyber-physical systems security vendor offering asset visibility, threat detection and AI-assisted analysis.

Where it falls short as an AI SOC:

• Mitsubishi Electric, which sells industrial automation and control products, completed its roughly $1 billion acquisition of Nozomi Networks on January 28, 2026 (SecurityBrief). Nozomi says it will remain vendor-neutral as an independent subsidiary (Nozomi Networks). Multi-vendor plants should still validate that commitment in contracts.
• Nozomi focuses on OT and IoT security. Enterprise IT detection, SIEM correlation and broader SOAR remain in separate tools.

How Seceon compares: Seceon is independent of any industrial equipment vendor and correlates OT activity with IT, identity, cloud and endpoint telemetry on one engine.

4. Dragos

What it is: An industrial cybersecurity platform for OT asset visibility, vulnerability management, threat detection and response playbooks, backed by Dragos threat intelligence.

Where it falls short as an AI SOC:

• Dragos unifies IT and OT security through third-party SIEMs. Its listed SIEM integrations include Microsoft Sentinel, Splunk, IBM QRadar and Fortinet FortiSIEM (Dragos).
• The Sentinel integration requires configuring syslog forwarding through the Azure Monitor Agent and deploying an analytics rule to turn Dragos data into Sentinel incidents (Dragos solution brief).

How Seceon compares: In Seceon, OT findings flow into the same aiSIEM engine natively. There are no syslog pipelines or analytics rules to build, and one kill chain spans IT and OT.

5. Armis (now part of ServiceNow)

What it is: A cyber exposure management platform that discovers and monitors connected assets across IT, OT, IoT and medical devices.

Where it falls short as an AI SOC:

• ServiceNow closed its approximately $7.75 billion acquisition of Armis on April 20, 2026 (ServiceNow 8-K). Armis Centrix remains available standalone, with deeper ServiceNow integration planned over time (SecurityBrief). Buyers should plan for roadmap change.
• Its strength is asset visibility and exposure management, with remediation routed through workflow platforms. Detection correlation and SOC response rely on other tools.

How Seceon compares: Seceon combines asset discovery with real-time detection, AI investigation and automated, OT-safe response in one platform.

6. Microsoft Defender for IoT

What it is: Microsoft’s OT and IoT network monitoring service, managed through the Azure portal and integrated with Microsoft security tools.

Where it falls short as an AI SOC:

• The legacy on-premises management console is no longer available for download after January 1, 2025 (Microsoft Learn). Microsoft now recommends cloud services or existing IT infrastructure for central monitoring (Microsoft Learn).
• That shift makes centralized management harder for air-gapped and sovereign OT sites that cannot connect to the cloud.

How Seceon compares: Seceon runs all processing, including its SeraAI language model, on-premises or fully air-gapped, with no cloud dependency and support for unidirectional data diodes.

OT, IoT and ICS Use Cases: How the Platforms Compare

Quick answer: In real OT and IoT attack scenarios, Seceon detects and responds on one platform, while standalone OT tools detect in one console and depend on a separate SIEM and SOAR to correlate and act. The difference shows most clearly when an attacker moves from IT into OT.

Best Picks by Buyer

Buyer’s Checklist: 8 Questions to Ask Every AI SOC Vendor About OT

1. Passive by design? Can the platform discover and monitor OT assets with zero agents on PLCs, RTUs, DCS and HMIs, using TAP or SPAN only?
2. Protocol depth. Which industrial protocols are parsed natively (Modbus, DNP3, IEC 61850, OPC-UA, BACnet, PROFINET), and how fast are custom parsers delivered?
3. One engine or two? Are IT and OT events correlated in the same detection engine, or forwarded to a separate SIEM?
4. Autonomy with evidence. What share of L1 alerts does the AI resolve on its own, and does every conclusion link to retrievable evidence?
5. OT-safe response. Does automated response support safety interlocks, protected assets and human approval for irreversible actions?
6. Air-gap ready. Can the full stack, including SIEM, SOAR and the AI model, run on-premises or air-gapped with data-diode support?
7. Standards. Does it report against IEC 62443 zones and conduits, NERC CIP and NIST SP 800-82, and map to MITRE ATT&CK for ICS?
8. Tool count. How many separate products are needed to go from OT visibility to automated response?
