NetSentries ICS & OT Security works with critical infrastructure operators, industrial OEMs, and energy companies to assess and harden operational technology environments. Our zero-disruption methodologies are purpose-built for live production — delivering actionable risk intelligence without impacting availability or safety systems.
01
SCADA, DCS & FIELD DEVICE SECURITY
ICS & SCADA Security Assessment
Purpose-built assessments for SCADA, DCS, and field device environments — identifying exploitable weaknesses in supervisory systems, controllers, and industrial protocols without disrupting production availability. Our passive methodology is designed for environments where downtime is not an option.
•
SCADA & DCS security evaluation — supervisory system and HMI security against known threat scenarios
•
PLC, RTU & field device review — controller security posture and authentication mechanism assessment
•
Industrial protocol analysis — evaluation of control protocol integrity, authentication, and encryption
•
Passive zero–disruption assessment — non-invasive techniques designed for live production environments

IT/OT CONVERGENCE & NETWORK ARCHITECTURE
OT Architecture & Network Segmentation
Assessing the boundaries between enterprise IT and operational technology — validating network segmentation, DMZ architecture, and remote access controls that prevent adversaries from pivoting into safety-critical production systems. We evaluate against the Purdue reference model and zone/conduit principles.
•
IT/OT segmentation validation — architecture review against Purdue model and zone/conduit principles
•
DMZ & boundary control testing — data diode effectiveness, historian isolation, and broker segmentation
•
Remote access governance review — vendor access controls, jump-host security, and session management
•
Safety system independence assurance — SIS and ESD isolation to prevent cross-domain compromise

THREAT LANDSCAPE & INCIDENT READINESS
OT Threat Intelligence & Resilience Testing
Evaluating your operational technology environment against real-world industrial threat actors — from nation-state campaigns targeting energy infrastructure to ransomware groups pivoting through IT into OT. We validate your detection capabilities and incident response readiness for OT-specific scenarios.
•
OT–specific threat landscape analysis — profiling adversaries targeting your industry and infrastructure
•
Adversary simulation for industrial environments — controlled red team exercises within OT boundaries
•
Incident response readiness assessment — OT-specific playbook validation and tabletop exercises
•
Recovery & continuity validation — backup integrity, failover testing, and restoration procedures

STANDARDS ALIGNMENT & EXECUTIVE REPORTING
Industrial Compliance & Resilience Reporting
Delivering compliance-ready evidence aligned to global industrial cybersecurity and functional safety standards — enabling regulatory submissions, board reporting, and cyber insurance underwriting with structured risk narratives and remediation roadmaps.
•
IEC 62443 & NERC CIP alignment — gap analysis and evidence mapping for industrial certification
•
Functional safety framework compliance — IEC 61511 and IEC 61508 integration with cybersecurity
•
NIS2 & EU CRA regulatory readiness — European regulatory preparedness and documentation
•
Executive & board–level reporting — risk-scored deliverables with Purdue-mapped impact analysis
