About CR Vertex

You work directly with the expert, not a sales team.

Founder-led delivery

Direct access to the person designing, implementing, and documenting your infrastructure.

CR Vertex is the founder-led practice of Christian “Reichi” Reichinger, bringing hands-on engineering judgement to networks that have to be secure, observable, and boringly reliable. From first sketch to rack, firewall rule, access point, camera, automation, and documentation, the work is owned end to end by the person designing it.

Process

Structured enough for critical systems, flexible enough for real sites.

Network projects succeed when discovery, design, implementation, and operations are connected. CR Vertex keeps those stages visible so stakeholders know what is changing and why.

01 / Discover

Map the real environment

Capture sites, circuits, switching, WiFi, firewalls, cameras, cloud dependencies, business constraints, and the operational pain points that are not visible in diagrams.

  • Asset baseline
  • Risk list
  • Priority roadmap

02 / Design

Turn requirements into an architecture

Translate business needs into VLANs, routing, firewall rules, RF plans, identity boundaries, monitoring signals, and a migration path that can be executed safely.

  • Target topology
  • Security model
  • Implementation plan

03 / Deploy

Implement with rollback paths

Stage devices, prepare configurations, schedule cutovers, validate client behavior, document changes, and keep a clear rollback option for critical network moves.

  • Configured systems
  • Validation results
  • Handover notes

04 / Operate

Make the network easier to run

Add monitoring, alerting, maintenance routines, backup strategy, runbooks, and lifecycle recommendations so daily operation becomes predictable after the project.

  • Runbooks
  • Monitoring checks
  • Lifecycle guidance

Project Showcase

Infrastructure work made visible.

Each engagement is shaped around the real environment: people, buildings, applications, constraints, risk, and growth.

Multi-site UniFi Deployments

Challenge
Fragmented sites needed centralized visibility without adding operational friction.
Solution
Standardized UniFi gateways, switching, access points, Protect cameras, VLANs, and monitoring playbooks across locations.
Business Impact
Predictable rollouts, faster troubleshooting, cleaner handover, and infrastructure that scales site by site.

High-density wireless

Enterprise WiFi Design

Challenge
Coverage existed on paper, but roaming, capacity, and interference hurt daily work.
Solution
Mapped RF conditions, tuned channels and power, segmented SSIDs, and validated client behavior after deployment.
Business Impact
Stable roaming, higher throughput, fewer support tickets, and a network users stop thinking about.

What You Get

Useful outcomes, not just installed equipment.

Every engagement is shaped around operational value: fewer unknowns, better visibility, safer changes, clearer documentation, and systems that can be maintained after the deployment is complete.

Architecture & migration plans

Clear technical plans that show how sites, networks, access policies, and cloud services fit together before hardware is touched.

Network diagramsIP/VLAN plansCutover strategyRollback steps

Security & segmentation reviews

Practical hardening for the parts that matter most: firewall policy, management access, guest networks, cameras, IoT, and remote administration.

Firewall reviewAccess boundariesAdmin hardeningGuest/IoT isolation

WiFi and UniFi optimization

Wireless work focused on roaming, channel planning, power levels, SSID design, client experience, and visibility in the UniFi platform.

FAQ

Practical answers before the first conversation.

A few common questions about how CR Vertex fits into existing teams, what technologies are covered, and what a finished engagement should leave behind.

Can CR Vertex work with an existing IT provider?

Yes. Engagements can be advisory, hands-on, or collaborative. The goal is to strengthen the environment without disrupting teams or established support relationships.

Is the work limited to UniFi and Ubiquiti?

No. UniFi is a strong focus, but projects often include firewalls, VPNs, switching, Linux services, cloud DNS, monitoring, automation, and smart building integrations.

What happens before a deployment starts?

A deployment starts with discovery, constraints, success criteria, and a practical migration plan. Critical changes include validation steps and a rollback path.

Do you provide documentation after the project?

Yes. Handover notes, diagrams, access boundaries, backup expectations, monitoring checks, and maintenance guidance are treated as part of the finished system.
