Technology Services That Fix Today’s Problems — and Design Tomorrow’s Systems

Technology Services That Fix Today’s Problems — and Design Tomorrow’s Systems

John Hargrove Consulting LLC and Evergreen Technology Solutions work together to help organizations stabilize critical technology now and intentionally design what comes next.
Our focus is practical, field-tested technology for businesses, utilities, public entities, and rural communities that cannot afford guesswork or downtime.

We Fix Technology That Is Not Working

When systems are unreliable, insecure, or poorly documented, we step in to diagnose, correct, and harden them.

Wireless and Network Systems

  • Troubleshooting and repair of Wi-Fi networks
  • Commercial wireless point-to-point (PTP) and point-to-multipoint links
  • Internal LAN/WAN performance issues and segmentation problems

Cybersecurity and Risk

  • Cybersecurity posture assessments
  • Identification of operational, policy, and training gaps
  • Practical remediation plans aligned with real-world operations

Stabilization and Recovery

  • Network clean-up and documentation
  • Configuration correction and performance tuning
  • Transition from “fragile” systems to reliable, supportable infrastructure

The objective is simple: restore confidence, uptime, and clarity.

We Plan, Design, and Build Technology the Right Way

Beyond repair, we help organizations design systems that scale, comply, and endure.

The question for every OT operator reading this report is whether their current architecture gives them a fighting chance to detect lateral movement before it reaches the consequence-critical pathways, and to recover with confidence when it does. If the answer is uncertain, the path forward is to start with consequence mapping and build from there.

From Signals to Systems: Engineering as Stewardship

A specification tells you what a component should do under controlled conditions. It doesn’t tell you what happens when that component is asked to operate for twenty years in a substation control panel with inadequate ventilation, marginal grounding, and legacy protocols it was never designed to handle.
