OT/ICS Security Services India — Industrial Cybersecurity for Manufacturing & Critical Infrastructure

OT/ICS Security Services India

India’s manufacturing sector is racing toward a $1 trillion output target by 2030, with 60% of manufacturers now deploying Industrial Internet of Things (IIoT) technology. Yet only 25% have robust Operational Technology (OT) security in place. A single ransomware attack on a SCADA system can halt production for weeks — costing crores per day. MDIT Services provides specialised OT/ICS Cybersecurity services in India, protecting industrial control systems, SCADA networks, PLCs, and IIoT infrastructure from targeted cyberattacks.

What We Secure

• SCADA (Supervisory Control & Data Acquisition) — remote monitoring and control systems
• PLC (Programmable Logic Controllers) — Siemens, Allen-Bradley, Schneider Electric, ABB
• DCS (Distributed Control Systems) — process automation in oil, gas, and chemicals
• IIoT Devices — sensors, actuators, edge gateways on industrial networks
• HMI (Human-Machine Interfaces) — operator workstations connected to plant networks
• IT/OT Network Boundaries — the convergence zone where enterprise IT meets plant floor OT

OT Security Assessment Methodology

We follow IEC 62443 (the international OT security standard) and NIST SP 800-82 guidelines:

1. Asset Discovery — passive network enumeration without disrupting live plant operations
2. Network Segmentation Review — Purdue Model assessment, IT/OT zone mapping
3. Vulnerability Assessment — OT-specific CVE scanning using Claroty, Nozomi Networks, Dragos
4. Protocol Analysis — Modbus, DNP3, EtherNet/IP, Profinet protocol security review
5. Remote Access Audit — VPN, RDP, vendor remote access paths
6. Incident Response Readiness — OT-specific IR playbook, detection capability

Industries We Serve

Manufacturing (automotive, pharmaceuticals, FMCG) · Oil & Gas (upstream, downstream, pipelines) · Power & Utilities (generation, transmission, distribution) · Water Treatment · Ports & Logistics · Steel & Metals

Why OT Security Is Now Urgent in India

• CERT-In critical infrastructure mandates — mandatory annual security audits for critical sector operators from September 2025
• The 2023 Indian oil refinery ransomware attack caused 72-hour production shutdown, estimated ₹150 crore loss
• Nation-state threat actors actively targeting Indian power grids and manufacturing (documented campaigns from 2022-2025)
• OT systems typically run 15-25 year-old unpatched software — impossible to patch, must compensate with network controls

Engagement Models

• OT Risk Assessment — passive assessment of one plant/facility (from ₹2,00,000)
• IEC 62443 Gap Assessment — measure current posture vs standard (from ₹1,50,000)
• OT Incident Response Retainer — 24×7 OT-specific IR support (₹15L-₹40L/year)
• Managed OT Security Monitoring — continuous OT network monitoring (₹25L-₹80L/year)

Note: All assessments conducted passively to avoid disrupting live production environments.
