Capabilities
Mach Defense provides engineering‑led OT and ICS cybersecurity capabilities focused on reducing systemic risk, improving resilience, and aligning security controls with the realities of industrial operations.
OT & ICS Security Architecture
Design and evaluation of OT system architectures with an emphasis on zoning, trust boundaries, communication paths, and failure containment. Focused on shaping environments so risk is constrained by design.
Network Segmentation & Zoning
Engineering segmentation strategies aligned with Purdue‑style models and operational constraints. Includes conduit definition, boundary protection, and validation of segmentation effectiveness.
Legacy & Long‑Lifecycle System Hardening
Risk reduction strategies for legacy controllers, unsupported operating systems, and vendor‑constrained environments where replacement is not feasible and uptime is critical.
Operational Security Engineering
Integration of security controls into maintenance workflows, change management processes, and operational procedures—ensuring controls remain predictable and sustainable over time.
Risk‑Informed Architecture Reviews
System‑level analysis of OT environments to identify architectural weaknesses, unsafe trust assumptions, and compounding risk—without relying on tool‑driven findings alone.
Compliance‑Aligned Engineering
Engineering support that aligns OT security decisions with recognized standards and regulatory expectations, including IEC 62443, NERC CIP, and NIS2—without treating compliance as the primary objective.
These capabilities are applied deliberately and selectively, with the goal of reducing real‑world cyber‑physical risk while preserving safety, uptime, and operational effectiveness in industrial environments.
