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.
All Services
Service
OT / ICS Security
Protect what keeps the lights on, the water clean, and the line moving.
Maverc engineers OT defense for environments where downtime is not an option. We work shoulder-to-shoulder with plant engineers to deliver visibility, segmentation, and response without disrupting operations.
Proof
Trusted across critical manufacturing, energy, water, and transportation operators.
Overview
What this engagement looks like
We bring IT-grade detection discipline to OT environments while respecting safety, availability, and engineering constraints. From passive asset discovery to IT/OT segmentation and ICS-aware incident response, we secure the environments regulators, insurers, and your customers care most about.
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

Our Approach
How we deliver
01
See
Deploy passive monitoring to discover every asset, protocol, and conversation on the plant floor.
02
Separate
Engineer IT/OT segmentation and secure remote access without breaking operations.
03
Sustain
Operate ICS-aware detection, run tabletops, and align controls to IEC 62443 and TSA directives.
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.
