Services
Protect your industrial control systems, SCADA networks, and operational technology from cyber threats - without disrupting production. Our OT-specialized engineers deliver zero-downtime assessments, Purdue Model segmentation, and 24/7 industrial threat monitoring for manufacturing, energy, and critical infrastructure.
01
The Reality
Attacks on industrial infrastructure grew 140% in 2025. Manufacturing is now the most targeted sector globally. The convergence of IT and OT has created attack surfaces that traditional security can't protect.
As OT networks connect to IT infrastructure for data analytics and remote access, they inherit IT-world threats - ransomware, phishing, and advanced persistent threats - that legacy OT systems were never designed to withstand.
Many ICS and SCADA systems run on end-of-life operating systems (Windows XP, outdated firmware) that cannot be patched without risking production downtime, leaving known vulnerabilities permanently exposed.
Unlike IT breaches that cause data loss, OT security failures can cause physical damage, environmental hazards, and endanger human safety - making the stakes exponentially higher.
02
Our Capabilities
Every service is designed specifically for industrial environments - prioritizing safety, availability, and process integrity above all else.
Passive, non-intrusive discovery of all ICS, SCADA, PLC, HMI, RTU, and DCS assets across your OT environment using protocol-aware scanning that never disrupts production operations.
Secure the bridge between IT and OT networks with Purdue Model-based segmentation, data diodes, DMZ architecture, and protocol-aware firewalls that allow business data flow while blocking lateral threats.
Comprehensive vulnerability assessment of SCADA systems, DCS controllers, and industrial networks using OT-safe testing methodologies that identify risks without affecting process availability.
Implement defense-in-depth segmentation based on ISA/IEC 62443 zones and conduits, isolating critical safety systems from business networks and external connectivity.
24/7 monitoring of OT protocols (Modbus, DNP3, OPC-UA, Profinet, EtherNet/IP) for anomalies, unauthorized commands, and cyber threats with industrial-protocol-aware detection rules.
Align your OT security posture with IEC 62443, NIST SP 800-82, NERC CIP, and sector-specific standards. Full gap assessment, roadmap, and implementation support for regulatory compliance.
03
Zero-Downtime Approach
Non-intrusive asset inventory, network topology mapping, and communication flow analysis of your entire OT environment - without installing agents or disrupting operations.
Comprehensive vulnerability analysis and risk scoring of OT assets, network architecture, and access controls - prioritized by safety impact and exploitability.
Implement segmentation, access controls, patching strategies, and compensating controls tailored to OT requirements where traditional IT security approaches don't apply.

Common questions about our operational technology and industrial control systems security services
OT (Operational Technology) security protects industrial control systems (ICS), SCADA, PLCs, and other systems that manage physical processes in manufacturing, energy, utilities, and critical infrastructure. In India, the rapid digitization of manufacturing (Industry 4.0), smart grid initiatives, and government digitization programs have dramatically increased OT cyber risk. Unlike IT breaches that cause data loss, OT security failures can cause production shutdowns, equipment damage, environmental hazards, and endanger human safety.
Never. We use 100% passive, non-intrusive methods for OT asset discovery and network analysis. Our engineers are trained in industrial protocols (Modbus, DNP3, OPC-UA) and understand that availability is the highest priority in OT environments. Active testing is only conducted during planned maintenance windows with full coordination with your operations team, and we always have rollback procedures in place.
We implement a defense-in-depth approach based on the Purdue Model and ISA/IEC 62443 zones and conduits: proper network segmentation between IT and OT zones, secure data diodes or DMZs for northbound data flow, protocol-aware firewalls at zone boundaries, identity-based access control for remote access, and continuous monitoring of cross-zone traffic for anomalies. This allows business data to flow for analytics while preventing lateral movement of threats from IT to OT networks.
We serve manufacturing (automotive, pharma, FMCG), power & utilities, oil & gas, water treatment, transportation, smart buildings, and any organization with industrial control systems. Our engineers have hands-on experience with major ICS vendors including Siemens, ABB, Schneider Electric, Honeywell, Rockwell Automation, and Emerson.
We align with IEC 62443 (Industrial Automation and Control Systems Security), NIST SP 800-82 (Guide to ICS Security), NERC CIP (for energy sector), ISA-99, and MITRE ATT&CK for ICS framework for threat modeling and detection use case development. For Indian organizations, we also map to CERT-In guidelines and sector-specific mandates from CERC, PNGRB, and other regulators.
OT security differs fundamentally from IT security in several ways: availability trumps confidentiality (uptime is everything), patching is often impossible on legacy systems, safety is a primary concern (physical harm potential), systems have 20-30 year lifecycles vs. 3-5 years for IT, protocols are industrial-specific (Modbus, DNP3, not TCP/IP), and any security control must never impact process safety. Our team has dedicated OT security engineers, not IT security professionals repurposed for industrial environments.
