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

Top Priority: Availability & Safety
Primary Concern: Physical safety of people & equipment
System Lifecycle: 15-30 years (legacy systems)
Network Model: Air-gapped / isolated networks
Patching: Infrequent; requires outage windows
Protocols: Modbus, DNP3, OPC, EtherNet/IP
Incident Impact: Physical damage, environmental hazard

IT / Enterprise Security

Top Priority: Confidentiality & Integrity
Primary Concern: Data protection & privacy
System Lifecycle: 3-5 years (regular refresh)
Network Model: Internet-connected / cloud
Patching: Frequent; automated patch cycles
Protocols: TCP/IP, HTTP/S, SSH, TLS
Incident Impact: Data breach, financial loss

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.

1

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.

2

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.

3

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.

4

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.
