Case Study: City of Geel achieves faster root-cause detection and improved application performance with ExtraHop

City of Geel dramatically improves application performance with ExtraHop

The City of Geel, a Belgian municipality of about 40,000 people, relied on a seven-person IT team to manage dozens of critical applications across 46 locations and a mix of legacy and cloud systems. That complexity—covering ERP, emergency response, medication distribution, e‑commerce and VDI—left the team without centralized visibility, leading to slow troubleshooting, risky assumptions, and incidents such as 15‑minute VDI logins that threatened a desktop migration.

By deploying ExtraHop’s wire‑data analytics appliance (non‑disruptively via a single network tap), Geel gained cross‑tier, real‑time visibility into L2–L7 traffic. The team now identifies root causes twice as fast, resolved the VDI slow‑login issue by pinpointing a central client, antivirus and router configuration, gets proactive alerts, improves vendor collaboration, and delivers faster, more reliable application performance to users.
