OT/ICS/SCADA Security Assessment & Protection
Safeguard your operational technology environments from cyber threats. Our ICS-certified engineers assess and harden SCADA systems, PLCs, and industrial networks without disrupting critical operations.
OT Security vs IT Security
Operational technology environments have fundamentally different security priorities, constraints, and risk profiles compared to traditional IT systems.
OT / Industrial Security
IT / Enterprise Security
OT/ICS Security Assessment Areas
We evaluate every layer of your operational technology environment using ICS-specific methodologies and tools that prioritize safety and continuity.
SCADA Security
Comprehensive assessment of Supervisory Control and Data Acquisition systems including historian servers, communication channels, and operator workstations.
PLC/HMI Security
Security evaluation of Programmable Logic Controllers and Human-Machine Interfaces, including firmware analysis, authentication controls, and logic integrity verification.
Network Segmentation (IT/OT)
Review of demilitarized zones (DMZ), firewall rules, and segmentation between corporate IT and operational technology networks to prevent lateral movement.
Protocol Analysis (Modbus, DNP3, OPC)
Deep-packet inspection and analysis of industrial protocols for unauthorized commands, plaintext credentials, and exploitation of protocol-level vulnerabilities.
Remote Access Security
Assessment of VPN configurations, jump servers, vendor remote access, and multi-factor authentication controls for OT environment connectivity.
Patch Management
Evaluation of OT-specific patch management processes, compensating controls for unpatchable legacy systems, and vulnerability prioritization strategies.
Industry Frameworks & Standards
Our assessments align with internationally recognized ICS security standards and regulatory requirements.
NIST SP 800-82
ICS Security Best Practices
Guide to Industrial Control Systems Security providing a comprehensive framework for securing SCADA, DCS, PLC, and other ICS environments.
IEC 62443
Industrial Automation Security
International standard series for Industrial Automation and Control Systems security, defining security levels and zones for OT environments.
NERC CIP
Electric Grid Protection
North American Electric Reliability Corporation Critical Infrastructure Protection standards mandatory for bulk electric system operators.
ISA/IEC 62443
Security Lifecycle Management
ISA-developed standards adopted by IEC for securing industrial automation and control systems across all critical infrastructure sectors.
Our OT Assessment Methodology
A structured, safety-first approach to evaluating and strengthening your industrial control system security.
Asset Discovery & Inventory
Passive and active discovery of all OT assets, including PLCs, RTUs, HMIs, historians, and network devices. We build a comprehensive asset inventory with firmware versions, communication paths, and criticality ratings.
Vulnerability Assessment
Non-disruptive vulnerability scanning and manual analysis of OT components using ICS-specific tools. We identify misconfigurations, default credentials, known CVEs, and protocol-level weaknesses without impacting operations.
Segmentation Review
Analysis of network architecture, firewall rules, and data flows between IT and OT zones. We verify Purdue Model implementation, DMZ effectiveness, and identify unauthorized cross-zone communication paths.
Incident Response Planning
Development of OT-specific incident response procedures that prioritize safety and availability. Includes tabletop exercises, runbook creation, and coordination protocols between IT and OT teams.
Industries We Protect
We have deep experience securing operational technology across critical infrastructure sectors.
Energy & Utilities
Power generation, transmission, and distribution systems including smart grid infrastructure and NERC CIP compliance.
Oil & Gas
Upstream, midstream, and downstream operations including pipeline SCADA, refinery DCS, and offshore platform control systems.
Manufacturing
Discrete and process manufacturing environments including robotics, MES/SCADA integration, and Industry 4.0 security.
Water Treatment
Water and wastewater treatment facilities, distribution systems, and chemical dosing control systems.
Transportation
Rail signaling systems, traffic management, port operations, and aviation control infrastructure.
Mining
Autonomous and semi-autonomous mining operations, ventilation control, and material handling systems.
