Case Study

Network segmentation review for a commercial services firm

A mixed environment got a practical segmentation plan without being told to start over.

This anonymized engagement sits inside the Network and Systems Security Review. The real problem was trust boundaries, vendor paths, and layout clarity across office, camera, and connected systems.

Problem

Growth layered the environment faster than structure did

Office workstations, wireless networks, cameras, vendor-access systems, and connected devices had been added over time without a clean separation plan. Remote access had expanded, vendor accounts were still active, and nobody had a clear picture of what should talk to what.

Why it mattered

The team did not need a dramatic rebuild. It needed a clearer answer to which systems belonged together, which trust relationships were unnecessary, and which quick wins would reduce exposure without disrupting operations.

Work Performed

What the engagement actually covered

Review

Layout and exposure review

Reviewed the current network layout, internet-facing services, and remote access setup across office and shop functions.

Mapping

Segmentation planning

Mapped the systems that needed stronger separation between office users, cameras, vendor access, and connected devices.

Quick wins

Identity and access cleanup

Flagged weak points around MFA, password hygiene, and over-permissive access while keeping the plan matched to the current environment.

Before

Too much implicit trust

  • Office systems, cameras, vendor paths, and shop devices had grown together without enough separation
  • Remote access had expanded beyond what the team could clearly track
  • The environment felt riskier than the team could easily explain
After

Practical remediation sequence

  • The client left with a phased plan instead of a generic recommendation to rebuild
  • Unnecessary trust between systems was easier to see and prioritize
  • Follow-through got easier because the plan matched budget and operational reality
Outcome

Clear remediation sequence using current gear

Outcome snapshot

What changed operationally

Problem
Mixed systems with unclear trust boundaries
What was done
Delivered a phased segmentation and cleanup plan matched to the current environment
Operational result
The team could act on a clear sequence instead of debating a vague future-state plan

Why this matters

"We had office systems, cameras, and connected devices sharing the same network. Their assessment gave us a segmentation plan we could actually implement with the gear we already owned."
