OT Network Monitoring & SOC

OT Network Monitoring & Industrial SOC Detection That Survives the Plant Floor

99.9%

Threat detection and prevention rate

EuroShield advises industrial operators, data center developers, and critical-infrastructure regulators on the design, pilot, and scaling of operational technology monitoring and industrial SOC capability. Most OT monitoring programmes fail for one of three reasons: a platform was procured before a use-case catalogue existed; telemetry was assumed rather than engineered; or the SOC was stood up as a

carbon copy of the IT SOC and drowned in alerts no analyst could triage. Our engagements are structured to remove all three failure modes before procurement, not after.

Vendor-neutral, by commercial structure. We do not resell Claroty, Nozomi Networks, Dragos, Microsoft Defender for IoT, Tenable OT, Forescout, Armis, or any adjacent platform. We evaluate them against site constraints — protocol coverage, deployment model, telemetry depth, licensing economics, and integration with the customer’s existing SIEM and IR workflow — and the recommendation is the one that fits the environment.

Vendor-neutral, by design. We do not resell firewalls, visibility platforms, or remote-access tools. We specify what the site needs against IEC 62443 SL targets and document the trade-offs — procurement retains full commercial freedom.

Three delivery stages, scoped distinctly

Design & Proof of Concept (4–8 weeks). Use-case catalogue, telemetry architecture, platform shortlist, structured PoC against two to three candidates on a representative site slice.

Pilot (2–4 months). Controlled rollout across one or two representative sites with runbooks, SOC integration, and measured detection outcomes.

Scale & Operate. Multi-site rollout, IT/OT SOC convergence, retained advisory, and a measurement model that outlasts the initial programme.

Monitoring Design & Architecture

Use-case catalogue development — MITRE ATT&CK for ICS mapping, site-specific threat scenarios, and regulator-driven detection obligations
Telemetry architecture: span-port, tap, aggregation, and sensor placement sized to zones and conduits, not to vendor defaults
Protocol coverage validation across Modbus, DNP3, S7, OPC-UA, IEC 61850, EtherNet/IP, PROFINET, and proprietary DCS traffic
Detection-engineering baseline: asset inventory feed, network baseline, behavioural modelling, and signature content strategy
Data-flow and retention design against NIS2 evidence-retention expectations and sector-specific obligations

Platform Selection & PoC

Vendor-neutral shortlisting against the use-case catalogue — typical candidates include Claroty Continuous Threat Detection / xDome, Nozomi Networks Guardian, Dragos Platform, Microsoft Defender for IoT, Tenable OT Security, Forescout eyeInspect, and Armis; selection driven by environment, not partnership
Structured PoC methodology with scored evaluation criteria (detection fidelity, false-positive rate, protocol breadth, OT-engineer usability, SIEM integration, licensing model, support footprint in your region)
Independent, signed PoC report — deliverable in a format procurement can use to defend the selection internally
Commercial structuring support: licensing model review, multi-year economics, and renewal exposure

Industrial SOC — Stand-Up & Convergence

Operating model design: in-house, hybrid, or MSSP — scoped to scale, regulatory, and data-sovereignty constraints
SOC tier design for OT context: Tier 1 triage with OT-engineer involvement, Tier 2 correlation, Tier 3 hunt and IR integration
IT/OT convergence architecture: SIEM integration (Splunk, Microsoft Sentinel, IBM QRadar, Google Chronicle, Elastic Security — neutral across), SOAR playbook design, unified case management
Ticket, escalation, and shift-handover design suited to operations' change-management cadence, not IT's
Analyst enablement: OT-specific training curriculum, tabletop programmes, and competence framework
MSSP / co-managed SOC advisory — RFP scaffolding, SLA structure, and exit-option design (because MSSP exits are where continuity risk concentrates)

Detection Engineering & Content

Use-case lifecycle: author, validate, tune, retire — governed, not ad-hoc
Detection-as-code patterns adapted to OT constraints and platform capabilities
Threat intelligence integration: ICS-specific feeds, vendor advisories, and national CERT/sector ISAC inputs
Purple-team validation of detection coverage against MITRE ATT&CK for ICS — tested, not asserted
