Operational technology and industrial control systems weren't designed with cybersecurity in mind. We make sure attackers can't exploit that — without disrupting the operations you depend on.
The convergence of IT and OT has connected critical infrastructure to the internet — and to a new class of sophisticated, persistent adversaries. Energy grids, water treatment facilities, manufacturing plants, and transportation networks are now primary targets for nation-state actors and ransomware groups who know that operational disruption is worth far more than stolen data. The stakes have never been higher.
VANGUR AI's industrial security practice is led by specialists who understand both the cybersecurity and operational sides of OT environments — the unique protocols, the legacy systems, the zero-tolerance for downtime, and the regulatory frameworks that govern critical infrastructure. We deliver passive, non-intrusive security monitoring, network segmentation architecture, and purpose-built incident response that protects your operations without ever putting them at risk.
Our passive monitoring approach provides complete OT asset discovery and network traffic analysis without sending a single packet that could disrupt PLCs, RTUs, or HMIs. We understand that in OT environments, the monitoring tool must never become the threat.
Proper IT/OT network segmentation, industrial DMZ architecture, and OT-aware firewall rule management form the backbone of a defensible industrial environment. We design, implement, and continuously validate the boundaries that keep attackers out of your operational network.
Passive, protocol-aware discovery of every PLC, RTU, HMI, engineering workstation, and historian in your OT environment — without sending disruptive scan traffic.
Industrial DMZ design, Purdue model implementation, OT/IT boundary enforcement, and micro-segmentation that limits attacker movement without impacting operations.
Deep packet inspection of Modbus, DNP3, IEC 61850, EtherNet/IP, and other industrial protocols to detect unauthorized commands, anomalous traffic, and protocol abuse.
Behavioral baseline monitoring for industrial networks — detecting reconnaissance, lateral movement, and manipulation of control systems before safety or operations are impacted.
Compliance program development and audit preparation for IEC 62443, NERC CIP, NIST SP 800-82, and sector-specific regulatory requirements for critical infrastructure.
Purpose-built IR playbooks for industrial environments — coordinating cybersecurity response with operations and safety teams to contain incidents without causing process failures.
Let's build an OT security program that keeps operations safe and adversaries out.
