The Challenge

Air gaps are gone. IT/OT convergence, remote vendor access, and aging Windows assets in plants create a soft target for ransomware and nation-state actors. Traditional IT security tools blind-side controls engineers — or worse, trip safety systems.

Overview

How this solution works

OT environments don't tolerate downtime, and they don't tolerate active scanners. Maverc's OT Defense Suite combines passive asset discovery, protocol-aware anomaly detection, and Purdue-model segmentation engineering — delivered by engineers who've worked in plants, substations, and refineries. We protect uptime first, then security.

Outcomes you'll see

Complete asset inventory without touching a single PLC
IT/OT segmentation that survives audits and pen tests
Detection of unauthorized changes to control logic
Reduced ransomware blast radius across plant networks
Compliance-ready posture for IEC 62443, NERC CIP, TSA pipeline

Capabilities

What's included

Engineered components delivered as a unified, outcome-driven platform.

Passive asset discovery (Nozomi, Claroty, Tenable.OT, Dragos)

Protocol-aware anomaly detection (Modbus, DNP3, S7, OPC-UA, IEC-61850)

Purdue-model network segmentation engineering

Secure remote access for vendors and engineers

OT-specific incident response with safety-first playbooks

ICS vulnerability management (no active scanning)

IEC 62443 & NIST 800-82 program development

Tabletop exercises with controls and operations teams

Building Blocks

Core components

Asset Visibility

Passive deep-packet inspection identifies every PLC, HMI, RTU, historian, and engineering workstation — with firmware versions and known CVEs.

Network Segmentation

Engineer Purdue-model zones and conduits with industrial firewalls, data diodes, and unidirectional gateways where safety demands it.

Threat Detection

Behavioral baselines for control traffic — alert on rogue programming sessions, unauthorized firmware changes, and protocol abuse.

Incident Response

OT-trained responders who understand process safety, will never recommend a blind shutdown, and coordinate with plant operations.

Delivery Model

How we deliver

Assess

Site walk-down, passive sensor deployment, and crown-jewel identification with operations stakeholders.

Architect

Design segmentation, secure remote access, and monitoring — reviewed with controls engineers before any change.

Implement

Phased rollout during planned outages, with full rollback plans and operations sign-off at every gate.

Operate

24/7 OT-aware SOC monitoring, quarterly threat hunts, and annual IEC 62443 maturity reviews.

FAQ

Common questions

Will your tools impact production?

No. Discovery is 100% passive via SPAN ports or TAPs. We never actively scan a control network without explicit, scheduled approval.

Do your responders understand process safety?

Yes. Our OT engineers come from controls, automation, and plant operations backgrounds — not just IT security.

Can you support NERC CIP or TSA pipeline directives?

Yes. We map every control to the relevant framework and produce audit-grade evidence.
