Zero WiFi Security Breaches and 100% Audit Pass Rate Across 32 Federal Facilities

The Challenge

A federal regulatory agency with 5,000 employees across 32 facilities nationwide needed to bring its WiFi authentication into compliance with NIST 800-63B guidelines. The existing infrastructure was a patchwork of on-premises RADIUS servers, some running software that hadn't been updated in years.

Certificate management was the most painful aspect. The agency's PKI team spent roughly 60% of their time on WiFi certificate lifecycle management - issuing, renewing, revoking, and troubleshooting certificates across thousands of devices. When a certificate expired - which happened more often than anyone wanted to admit - the affected employee simply couldn't connect to WiFi until the PKI team manually intervened.

Audit preparation was equally burdensome. Before each compliance review, a team of three spent two full weeks compiling WiFi access logs, certificate status reports, and authentication event histories from disparate systems. Even with that effort, auditors regularly flagged gaps in the documentation.

• On-prem RADIUS servers across 32 facilities with inconsistent configurations
• Manual certificate management consuming 60% of PKI team capacity
• Two-week audit preparation cycle for WiFi access controls alone
• Mix of managed laptops and BYOD devices requiring different auth methods
• No centralized visibility into authentication events across facilities
• Previous failed migration attempt due to on-prem RADIUS scaling limitations

The Solution

The agency deployed IronWiFi's WPA-Enterprise solution with Cloud PKI and SCEP (Simple Certificate Enrollment Protocol) across all 32 facilities in a 12-week phased rollout. Each phase included a security review gate before proceeding to the next batch of facilities.

Cloud PKI automated the entire certificate lifecycle. Managed devices enrolled certificates automatically via SCEP integration with the agency's MDM platform. BYOD devices went through a self-service enrollment portal that verified identity against the agency's directory before issuing a device certificate. Certificate renewal happened automatically 30 days before expiration - no more emergency calls to the PKI team.

Conditional access policies enforced device trust at the authentication layer. Only devices with valid certificates, current OS patches, and approved security configurations could access the secure WiFi network. Non-compliant devices were automatically redirected to a remediation network with limited access and instructions for getting into compliance.

Every authentication event - successful or failed - was logged with full context: user identity, device fingerprint, certificate status, facility location, and timestamp. The centralized dashboard gave auditors everything they needed in a single report that could be generated in minutes.

• WPA-Enterprise with EAP-TLS certificate-based authentication
• Cloud PKI with automated certificate lifecycle management
• SCEP integration with MDM for zero-touch managed device enrollment
• Self-service BYOD enrollment with directory identity verification
• Conditional access enforcing device trust and patch compliance
• Complete audit trail for every authentication event across all facilities

The Results

The security and compliance improvements were immediate and measurable. The agency passed its next three compliance audits with zero WiFi-related findings - a first in the agency's history.

The PKI team's workload transformed overnight. Certificate management that previously consumed 60% of their time now runs automatically. The team was reassigned to higher-value security initiatives. Certificate-related WiFi outages - which had been a weekly occurrence - dropped to zero.

The conditional access policies caught several compliance issues proactively. Devices that fell behind on OS patches were automatically quarantined until remediated, preventing potential vulnerabilities from ever reaching the secure network. The agency's security posture improved not just for WiFi, but across the board, as the conditional access framework became a model for other access control implementations.

Timeline

The deployment followed a 12-week phased approach, with security review gates between each phase. Weeks 1-2 covered the headquarters facility as a pilot. Weeks 3-6 rolled out to 10 regional offices. Weeks 7-10 covered the remaining 21 facilities. Weeks 11-12 were dedicated to final security review, documentation, and knowledge transfer. Each facility cutover was completed in a single maintenance window with zero downtime.
