Strategy, Scoping & Selection
Endpoint inventory and classification: engineering workstations, HMIs, historians, jump servers, industrial PCs, embedded Windows/Linux devices, thin clients, data-center management endpoints
OEM compatibility matrix — Siemens, Rockwell, Schneider, ABB, Emerson, Honeywell, Yokogawa, GE — with documented support-contract implications for each candidate agent
Use-case catalogue tied to MITRE ATT&CK for ICS and industrial threat scenarios (living-off-the-land in engineering tooling, USB-borne malware, signed-driver abuse, RMM misuse on OT hosts)
Vendor-neutral shortlisting against documented criteria: agent resource footprint, kernel-versus-user-mode behaviour, update-management options, offline operation, OT-protocol awareness, regional data-residency, SIEM export fidelity, licensing model, and support footprint in your region
Structured PoC methodology with scored evaluation on a representative slice — engineering workstations, one HMI family, one historian, one jump server — before any plant-wide commitment
Independent signed PoC report — procurement-defensible, scored against published criteria, not a vendor deck
Deployment & Integration
- Staged deployment plan sequenced against OEM-maintenance windows and planned outages — never against vendor delivery timelines
- Agent configuration baselines differentiated by endpoint class (an HMI is not a developer laptop; the policy cannot be)
- Update and signature-management strategy: offline, staggered, and with explicit rollback paths for process-critical hosts
- Integration with industrial OT visibility platforms (Claroty, Nozomi, Dragos, Defender for IoT, Tenable OT, Forescout, Armis — named neutrally) so agent telemetry and passive network telemetry correlate rather than duplicate
- SIEM integration (Splunk, Microsoft Sentinel, QRadar, Chronicle, Elastic — neutral across): normalised schema, retention design, and alert-to-SOC-workflow wiring
- Jump-host and privileged-access endpoint hardening, engineered against IEC 62443 SR 1 and SR 2 (identification and use control)
- Data Center endpoint coverage for AI-ready builds: GPU-host management endpoints, out-of-band management (BMC/iLO/iDRAC), building-management workstations
Detection, Tuning & Coverage
- OT-specific detection content: engineering-software misuse, controller programming tool abuse, unauthorised firmware push, USB-borne payloads in the engineering station chain, protocol-tunnel establishment over IT/OT boundary
- False-positive tuning under production load — a nuisance-alert rate an OT-context SOC can actually absorb
- Coverage validation against MITRE ATT&CK for ICS — tested, not asserted; purple-team validation available cross-linked with §3.3 VAPT
- Detection content lifecycle: authored, validated, tuned, retired — governed by a content-management playbook, not left to platform defaults
- Gap analysis between XDR/EPP coverage and passive OT monitoring (§3.4) — the overlaps and blind spots documented, not assumed away

Embedded & Device Fleet Protection
- Fleet-level protection strategy for embedded industrial devices where traditional EPP agents cannot run
- Host-based hardening: application allow-listing, integrity monitoring, and memory-protection strategies for legacy and embedded endpoints
- Firmware update and integrity verification workflows — IEC 62443-4-1 process alignment
- Cross-scope with EU CRA obligations for manufactured components (vulnerability handling, SBOM, secure-by-default configuration)
