Case Study: IZB Informatik-Zentrum achieves 1,000 hours/year maintenance savings and simplified complex firewall management with Barracuda Networks' NG Firewall

Simple Management of Highly Complex Firewall Infrastructure IZB Counts on Barracuda Networks

IZB Informatik-Zentrum, an ISO-certified IT service provider for banks and financial institutions, operates highly secure data centers and supports clients such as BayernLB and Deka Bank. Faced with a sprawling, multi-vendor firewall estate of more than 100 gateways, costly maintenance, non-multi‑tenant management tools and difficult troubleshooting, IZB sought a more efficient, standards-compliant solution.

IZB implemented Barracuda NG Firewall and the NG Control Center, replacing most legacy devices and centralizing management. The new setup delivered real‑time visualization, integrated sniffing and streamlined updates (one engineer completed a cluster update in 1.5 hours versus days previously), cutting roughly 1,000 man‑hours per year, reducing operating costs and producing a strong ROI.
