OT / ICS Security UAE Visibility · Detection · ComplianceProtect industrial control systems without disrupting operations
Artiflex IT designs, deploys and runs OT and ICS security programmes across the UAE, Oman and Saudi Arabia, covering manufacturing, utilities, oil and gas, water and critical infrastructure. We deliver Nozomi Networks, Claroty, Dragos, Tenable OT Security and Microsoft Defender for IoT as focused solutions and integrate them with the IT SOC you already operate. The conversation starts with your assets, protocols and safety constraints, not a SKU.
The Capability Map
The four pillars of industrial security
OT security is not one product. Visibility, detection, vulnerability management and compliance feed each other into one defensible posture across plants, substations and process control networks.
Asset & Network Visibility
Discover every PLC, RTU, HMI, historian and connected device on the industrial network through passive monitoring of ICS protocols. You cannot defend what you cannot see.
Focus: Nozomi Guardian · Claroty xDome
ICS Threat Detection
Detect anomalies and known attack techniques (controller reprogramming, rogue commands, malware, lateral movement) without disrupting operations, using protocol-aware analytics.
Focus: Nozomi · Claroty CTD · Dragos Platform
OT Vulnerability & Risk
Map known CVEs to the actual industrial assets you own, prioritise by exploitability and consequence, and produce risk evidence that operations and security both accept.
Focus: Tenable OT · Claroty · Nozomi
Compliance & Segmentation
Map controls to IEC 62443, NERC CIP, NESA and ADHICS, enforce Purdue-model zones and conduits, and produce auditable evidence for regulators and assessors.
Focus: All platforms · zone segmentation

No single vendor owns OT security. Our default UAE architecture pairs Nozomi for industrial visibility and NDR with Claroty for the most complex multi-protocol estates. Dragos wins in critical infrastructure, Tenable.ot for unified IT/OT vulnerability and Defender for IoT for Microsoft-aligned SOCs.
Detailed Comparison on OT / ICS Security Vendors
Strengths, blind spots and the deployment context each platform fits. Recommendations reflect UAE deployment patterns, not vendor tier.
Nozomi Networks (Guardian / Vantage)
Best for OT/IoT visibility & NDR (Recommended)
Why it wins
Co-founded in 2013, Nozomi brought the first AI-powered ICS visibility platform to market and was named a Leader in the Gartner Magic Quadrant for CPS Protection. Guardian performs deep packet inspection across industrial protocols, builds a digital-twin baseline of normal behaviour, and detects anomalies (atypical flows, controller-program changes, rogue devices, malware) without disrupting operations. Vantage provides SaaS-scale management across OT, IoT and IT. Integrates cleanly with Rapid7, Splunk and Sentinel for SOC correlation.
Consider
Purpose-built for OT and IoT, expect to pair with an IT SIEM for full IT/OT correlation. Sensor sizing and span/tap planning matters: scope this carefully during assessment.
Tenable OT Security (Tenable.ot)
Best for vulnerability-led OT programmes (Recommended)
Why it wins
Born from the 2019 Indegy acquisition, Tenable.ot extends the Tenable vulnerability-management programme into OT. Hybrid passive plus active discovery (active queries are safe, ICS-aware), asset-level CVE mapping, configuration drift detection and tight integration with Tenable.io and Tenable.sc for unified IT and OT risk reporting. The right answer when Tenable already runs your IT VM programme.
Consider
OT NDR depth is solid but not class-leading versus Nozomi or Dragos. The case for Tenable.ot is unified vulnerability reporting, not best-of-breed ICS detection alone.
Claroty (xDome / CTD)
Best for complex OT estates (Recommended)
Why it wins
Founded in 2015 with Team8 incubation, Claroty offers the broadest module set on the market: xDome (cloud), Continuous Threat Detection (CTD, on-prem), Secure Remote Access (SRA) and Edge for passive + active discovery. Particularly strong in pharma, healthcare (Medigate IoMT lineage) and manufacturing where heterogeneous device populations and remote vendor access dominate the risk surface.
Consider
More moving parts than competitors, plan a phased rollout (CTD or xDome first, SRA next) rather than everything at once.
Dragos Platform
Best for ICS-IR & threat intel
Why it wins
Founded in 2016 by Robert M. Lee and a team of former ICS-CERT and US Government ICS hunters, Dragos pairs the Dragos Platform with the WorldView threat-intelligence service and a Neighborhood Keeper community-defence model. The strongest pedigree for ICS-specific incident response, particularly in energy, oil & gas, water utilities and electricity grids where deep ICS protocol knowledge and threat-actor attribution matter most.
Consider
Specialist focus on heavy industry and critical infrastructure. Manufacturing or pharma buyers will often prefer Nozomi or Claroty for module breadth and IT-OT correlation depth.
Microsoft Defender for IoT
Best for Microsoft-aligned estates
Why it wins
Built on the 2020 CyberX acquisition, Defender for IoT brings agentless OT/IoT discovery and ML-based threat detection into the Microsoft security stack. Signals flow natively into Microsoft Sentinel and Defender XDR, making it the lowest-friction choice when M365 / Azure / Sentinel are already the SOC standard. Both cloud-managed and air-gapped on-premises management modes are supported.
Consider
Strongest where the SOC is already Microsoft-centric. For OT-first specialists (heavy industry, ICS-IR teams), Nozomi or Dragos still set the depth bar.

Decision Framework
Questions we ask before designing an OT programme
OT programmes get cleaner when the questions are direct. Walk through these and the architecture usually falls out by itself.
Do you actually know every asset on the industrial network?
If the answer is 'mostly' or 'we have a spreadsheet', start there. Asset visibility is the gate to everything else. Passive ICS-protocol discovery (Nozomi, Claroty) gives an accurate, non-disruptive inventory in days, not months.
Is the priority deep ICS-IR or broad IT/OT correlation?
For ICS-IR depth in critical infrastructure (energy, utilities, water), Dragos is the specialist. For unified IT/OT detection feeding the broader SOC, Nozomi is the most credible recommendation. For Microsoft-aligned shops, Defender for IoT.
What compliance frameworks must you prove?
IEC 62443, NERC CIP, NESA, ADHICS and ISO 27001 each demand specific OT evidence. Asset inventory, zone segmentation, change-control records and incident logs are the common spine, the right platform produces all four with minimum tuning.
Do you already run a Tenable IT vulnerability programme?
Then Tenable OT Security earns serious consideration: unified IT/OT vulnerability reporting, single risk-scoring methodology and one operator team. The case is operational, not best-of-breed ICS detection alone.
What is the IT/OT operational boundary, and who owns it?
OT security has to land somewhere on the org chart. Most successful UAE programmes co-own with operations (engineering accountable for safety, security accountable for detection). The right vendor must operate within that boundary.
What is the active-scan tolerance on the production network?
Some platforms (Claroty Edge, Tenable.ot) offer carefully tuned active queries that some plants accept and some refuse. Nozomi and Dragos remain fully passive by default. Match the deployment style to the plant culture.

Frequently asked questions
What businesses ask us most about OT security, ICS visibility and compliance.
Why is OT/ICS security different from IT security?
Industrial systems prioritise availability and safety over confidentiality, run for 20+ years on legacy protocols (Modbus, DNP3, EtherNet/IP, S7, BACnet, Profinet), often cannot be patched without a planned outage, and have safety consequences that IT systems do not. Tools, processes and people that work in IT will frequently break in OT. Purpose-built OT platforms understand this.
