Transforming County Government IT: A Comprehensive Network Infrastructure Modernization

A Northern California county government faced critical network infrastructure challenges that threatened their ability to deliver essential public services. Their legacy network suffered from performance bottlenecks, security vulnerabilities, and lacked the foundation to support modern wireless communications across their diverse portfolio of government facilities including courthouse, jail, sheriff's offices, health and human services, and administrative buildings.

CONVX partnered with this county through their trusted IT reseller to deliver a comprehensive network transformation through seven sequential engagements spanning 18 months. This multi-phase approach covering network assessment, remediation, and enterprise wireless deployment across five major facilities demonstrates both CONVX's ability to deliver complex projects and the client's growing confidence in our expertise. Each successful engagement led to expanded scope, culminating in enterprise wireless infrastructure supporting 150+ access points across 520,000+ square feet.

Key Outcomes:

• Delivered seven sequential engagements over 18 months demonstrating consistent execution and growing client confidence
• Completed comprehensive infrastructure transformation from assessment through full wireless deployment
• Eliminated critical network security vulnerabilities through comprehensive remediation
• Deployed enterprise wireless infrastructure supporting 150+ access points across 5 facilities
• Implemented secure guest access with proper network segmentation
• Established robust network monitoring and alerting capabilities
• Created scalable foundation supporting future technology initiatives

Legacy Network Vulnerabilities

The county's existing Cisco network infrastructure, while functional, contained several critical issues that posed operational and security risks:

• Network Topology Risks: Inter-site connections were configured as VLAN trunks rather than routed links, creating potential for spanning tree loops and site-wide outages from local network events
• Security Gaps: Network devices lacked proper access controls, with unsecured SNMP access and missing centralized logging capabilities
• Inconsistent Voice Implementation: VoIP services used an inefficient shared /16 network design, complicating management and troubleshooting
• Limited Monitoring: No comprehensive network monitoring system to detect and respond to performance or security issues

Wireless Coverage Gaps

The county's facilities lacked enterprise-grade wireless infrastructure to support:

• Staff mobility and productivity across diverse government operations
• Public services requiring wireless access for citizens
• Modern IoT devices for building management and security
• Secure guest access separate from government networks

Operational Requirements

As a government entity, the county required:

• High availability to support 24/7 public safety operations
• Strict security controls to protect sensitive government data
• Scalable infrastructure to support future technology initiatives
• Integration with existing Microsoft Azure and Active Directory environments

Building Trust Through Sequential Engagement Success

CONVX's relationship with this county government exemplifies our approach of building client confidence through consistent delivery.
