OT Security Services

Operational Technology (OT) Security focuses on protecting industrial control systems (ICS), supervisory control and data acquisition (SCADA) systems, and other critical infrastructure from cyber threats. Unlike traditional IT security, OT security protects physical processes in industries such as energy, manufacturing, transportation, and utilities, where cyberattacks can cause real-world damage to systems and safety.

Key OT Security Services & Solutions

1. OT Network Security & Segmentation

  • Implement Network Segmentation (IT/OT Separation) – Isolate OT systems from IT networks to prevent lateral movement of cyber threats.
  • Deploy Next-Generation Firewalls (NGFWs) – Use deep packet inspection (DPI) for industrial protocols like Modbus, DNP3, and IEC 104.
  • Secure Remote Access – Use Zero Trust principles, multi-factor authentication (MFA), and VPN alternatives to control vendor and employee access.

Recommended Solutions:

  • Palo Alto Networks OT Security
  • Cisco Cyber Vision
  • Fortinet FortiGate NGFW for OT

2. OT Threat Detection & Incident Response

  • Real-Time Threat Monitoring – Identify anomalies in industrial processes that indicate cyber threats.
  • AI-Powered Behavioral Analytics – Detect deviations from normal OT traffic patterns.
  • Incident Response & Threat Hunting – Rapidly contain and mitigate cyberattacks before they disrupt operations.

Recommended Solutions:

  • Nozomi Networks Guardian (AI-driven OT threat detection)
  • ClarotyxDome (Continuous OT monitoring)
  • Dragos Platform (ICS/SCADA-specific threat intelligence)

3. OT Vulnerability Management & Risk Assessment

  • Asset Discovery & Inventory Management – Identify all OT devices, PLCs, RTUs, and sensors in the environment.
  • Risk-Based Patching & Mitigation – Since OT systems can’t always be patched, use network isolation and compensating controls.
  • Penetration Testing for OT – Simulate real-world attacks to assess security gaps in SCADA & ICS networks.

Recommended Solutions:

  • Tenable OT Security (Continuous OT vulnerability scanning)
  • Siemens Industrial Security Services (Risk assessment & compliance)

4. OT Security Compliance & Governance

  • Ensure Compliance with Industry Standards:
  • NIST 800-82 (Industrial Control System Security)
  • IEC 62443 (Cybersecurity framework for OT)
  • NERC CIP (Power & energy sector security standards)
  • ISA/IEC 61511 (Safety Instrumented Systems)
  • Security Policy Development & Employee Training – Reduce human error by training staff on OT cybersecurity best practices.

Recommended Solutions:

  • Tripwire Industrial Visibility (Compliance & configuration monitoring)
  • Schneider Electric Cybersecurity Consulting

5. Industrial Endpoint & Workload Protection

  • Secure Industrial Endpoints & HMIs – Protect programmable logic controllers (PLCs), RTUs, and SCADA workstations.
  • Application Whitelisting – Allow only approved applications to run on OT endpoints.
  • Micro-Segmentation & Zero Trust for OT – Limit network access based on identity and role-based policies.
