Safety-first engineering
Our OT engineers come from plant-floor backgrounds. We never deploy active scans against a live PLC, we coordinate every change with engineering, and we keep your warranties and vendor support intact.

OT / ICS Security
Defense for the systems the rest of the country quietly depends on.
Power, water, manufacturing, and logistics are now front-line targets. The operators running those systems cannot accept downtime or a wrong move on the floor, and they cannot accept the alternative either. Maverc builds OT and ICS defense for those environments, designed around safety and uptime first, with every control built to support the work rather than disrupt it.
Proof
Trusted across critical manufacturing, energy, water, and transportation operators.
Overview
What this engagement looks like
We work alongside your controls engineers, not around them. Maverc brings IT-grade detection discipline to the plant floor, passive asset discovery, protocol-aware monitoring, Purdue-aligned segmentation, and incident response built for SCADA, PLCs, and DCS, without active scans or surprise reboots, and without disrupting the operations your customers, regulators, and insurers depend on.
Outcomes you'll see
- Visibility into every asset on the plant floor, without active scans
- Contain ransomware before it crosses the IT/OT boundary
- Demonstrate regulatory and insurance readiness
- Reduce vendor and field-engineer remote-access risk
Capabilities
What's included
Each engagement is scoped to your environment — these are the building blocks we draw from.
Passive asset discovery with Nozomi, Claroty, Dragos, Tenable.OT
IT/OT segmentation and Purdue-model reference architecture
Anomaly detection for SCADA, PLCs, HMIs, RTUs, and historians
Secure remote-access design for vendors and field engineers
ICS-aware incident response and tabletop exercises
Alignment to IEC 62443, NIST 800-82, NERC CIP, and TSA Pipeline directives
Cyber-physical risk assessments
Deep Dive
Where we go further
Purdue-aligned segmentation
We architect IT/OT segmentation aligned to the Purdue Reference Model, with conduits, zones, and unidirectional gateways where they belong, proven against the most common ransomware ingress paths.
ICS-aware incident response
Generic IR teams will brick a control system. Ours run plays designed for SCADA and DCS environments, with playbooks tested against ICS-tailored adversaries like Volt Typhoon, Sandworm, and Pipedream/Incontroller.
Deliverables
What you walk away with

FAQ
Common questions
Will your tools disrupt control systems?
No. We use passive, vendor-validated discovery and only recommend active techniques in safe windows with engineering approval.
Do you work with our control-system vendors?
Yes. We coordinate with Rockwell, Siemens, Schneider, Honeywell, Emerson, and others to keep warranties and support intact.
Can you help with TSA pipeline or NERC CIP compliance?
Yes, readiness, documentation, and ongoing operational evidence collection.
