Critical-Infrastructure Networking Built for Continuity

We engineer resilient networks for environments where downtime is unacceptable and failure modes are predictable: power loss, carrier disruption, physical intrusion, and evolving threat conditions.

Mainstream Technologies designs, deploys, and supports enterprise network architecture with hardened segmentation, multi-path connectivity, and operational visibility—built to sustain operations under stress.

Designed for: industrial sites • campuses • critical facilities • multi-site operations

What “Hardened Networking” Means

We implement disciplined architecture patterns that limit blast radius, enforce trust boundaries, and maintain connectivity during disruption.

Segmentation & Trust Boundaries

VLAN and policy-based segmentation for staff, guests, IoT, security devices, and operational systems— designed to contain incidents and simplify compliance.

High Availability & Failover

Redundant architectures and managed failover across carriers, circuits, and upstream paths— engineered to keep critical traffic moving.

Secure Remote Access

Encrypted site-to-site and remote access aligned with least-privilege principles—designed for controlled access, auditability, and operational simplicity.

Monitoring & Operational Awareness

Performance, uptime, and health monitoring that provides early warning—so issues are handled before they become incidents.

Built to withstand predictable failures
Power interruptions • carrier outages • equipment failures • misconfiguration • physical access events

Engineered for High-Consequence Environments

Critical networking is not about speed alone—it's about predictable behavior under pressure.

  • Industrial and warehouse environments
  • Critical facilities and high-value sites
  • Multi-site enterprises and campuses
  • Security-sensitive operations
  • Continuity and disaster-recovery planning
