Solution

OT / ICS Defense Suite

Defense for SCADA, PLCs, and DCS in the operations the country runs on.

Safety-aware monitoring, segmentation, and incident response built for the industrial systems behind the country's power, water, fuel, food, and goods, designed not to disrupt the work the rest of us depend on.

The Challenge

The air gap is gone. IT/OT convergence, third-party remote access, and aging Windows assets on the plant floor have made critical operations a soft target for ransomware crews and nation-state actors. Traditional IT security tools surprise controls engineers or, worse, trip the safety systems they were meant to protect. The cost of a wrong move is now measured in lost production, environmental impact, and worker safety.

Overview

How this solution works

Industrial environments can't tolerate downtime or active scanners, and the operators running them cannot accept the alternative either. Maverc's OT Defense Suite is built around that reality, with passive asset discovery, protocol-aware anomaly detection, and Purdue-aligned segmentation designed and operated by engineers who have worked inside plants, substations, and refineries. Safety and uptime come first, and security is built to support them rather than override them.

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

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.
