Managed OT/IoT SOC Services

A Managed OT/IoT SOC (Security Operations Centre) is a specialist outsourced service that provides continuous monitoring, threat detection, and incident response for operational technology (OT) and Internet of Things (IoT) networks. Unlike a traditional IT SOC, a managed OT/IoT SOC is staffed by analysts with expertise in industrial protocols, ICS/SCADA environments, and OT-specific threat actors, and uses passive monitoring techniques that do not disrupt production systems. Wizard Cyber’s Managed OT/IoT SOC operates 24x7x365 and covers environments of all sizes and industries.

IT security protects information technology systems — servers, endpoints, cloud platforms, and corporate networks — where the primary concern is data confidentiality, integrity, and availability. OT security protects operational technology systems — industrial control systems, SCADA, PLCs, sensors, and field devices — where the primary concern is operational continuity and physical safety.

OT devices often run proprietary protocols, have no agent support, cannot be patched frequently, and cannot tolerate the kind of active scanning or traffic injection that IT security tools routinely use. OT-specific monitoring must be passive, protocol-aware, and designed around the operational constraints of industrial environments.

Yes. Wizard Cyber’s Managed OT/IoT SOC is designed to provide unified visibility and correlated threat detection across both IT and OT environments. Using Microsoft Sentinel as the central SIEM and correlation engine, we aggregate alerts from across your IT and OT estate into a single view, enabling us to detect lateral movement between domains, identify cross-boundary threats, and respond with full context across your entire environment.

Wizard Cyber is a Microsoft-first organisation, and our primary OT/IoT monitoring platform is Microsoft Defender for IoT. However, we also have hands-on experience with a range of third-party OT/IoT security platforms including Forescout, Claroty, Nozomi Networks, and Armis. If your organisation has an existing investment in another platform, contact us to discuss how we can integrate it into our managed service.

The Purdue Model is a widely used reference architecture for industrial control system networks that organises OT environments into distinct functional zones — from enterprise IT at the top, through operations and control layers, down to field-level devices and sensors. It matters for OT security because threats often move between these zones, and effective monitoring requires visibility at every layer combined with an understanding of which cross-boundary communications are normal and which are anomalous. Wizard Cyber uses the Purdue Model as a reference framework when designing monitoring coverage for OT environments.

Yes. For organisations that have an internal security or IT team but lack dedicated OT/IoT security expertise, we offer co-managed arrangements where Wizard Cyber provides OT SOC capability alongside your existing team. This can range from augmenting your team with specialist OT analysts, to taking full responsibility for OT monitoring while your team handles IT security operations.

We work across a broad range of sectors including energy and utilities, manufacturing and industrial, critical national infrastructure, building management, healthcare, transportation and logistics, and oil, gas and chemicals. Our service is bespoke and designed around the specific requirements, protocols, and risk profile of your environment — not a generic framework applied uniformly across industries.

Deployment timelines depend on the size and complexity of your environment. For most organisations, we begin with a scoping and discovery phase to map your OT/IoT estate, agree monitoring architecture, and define response playbooks. Active monitoring typically begins within a few weeks of engagement start. Contact our team for a more specific timeline based on your environment.
