Economic WAN Infrastructure with Zero Downtime

Rettig ICC runs various business critical applications such as IBM Connections Cloud (a service similar to Microsoft’s Office 365), WebEx, and other SaaS solutions. Dedicated ERP software implementation including an online warehouse control system, that’s hosted in Austria, plays an essential role in the logistics and management of all manufacturing sites. Continuous availability of this system is crucial for cost-effective just-in-time production and downtimes are not tolerable. With Rettig ICC’s former firewall/ VPN solution without SD-WAN, simple backup traffic interfered with the business-critical just-in-time traffic of the ERP system unless it was routed via a separately procured uplink. This situation was costly and cumbersome to maintain, and a lot of available uplink bandwidth remained unused most of the time.

"Barracuda CloudGen Firewalls with SD-WAN allows us to reduce the number of MPLS lines by fifty percent."
- Erich Maierhofer, ICT Manager Infrastructure Services, Rettig Austria GmbH

When refreshing their infrastructure Rettig ICC was seeking a solution that offered maximum flexibility in leveraging MPLS, broadband and 3G/4G backup lines and ensured seamless availability. Constant Quality-of-Service and automatic failover in case of bandwidth fluctuations were also key requirements.

Secure Wide Area Network with SD-WAN and Zero-Downtime

Rettig ICC deployed Barracuda CloudGen Firewalls with built-in full next-generation security levels and secure SD-WAN at all locations. Combining the ability to send encrypted WAN traffic across multiple broadband lines with 4G as an additional backup allowed Rettig ICC to reduce the number of MPLS lines used for remote locations by 50 percent.

The game changer in the new infrastructure was Barracuda’s ability to measure bandwidth and latency in real-time and automatically redirect traffic leveraging performance-based transport selection. Onboard adaptive bandwidth protection ensures that business-critical ERP traffic will always utilize the best available uplink and be prioritized over any potential backup traffic. Barracuda CloudGen Firewalls even moves existing backup sessions seamlessly to alternative physical uplinks to accommodate ERP traffic.

Furthermore the IT department rates the internal certificate handling at Barracuda better compared to the former solution and the Barracuda Firewall Control Center made the management of a complex, European-wide IT infrastructure comparatively simple.

Benefits and Future Plans

The rollout of Barracuda CloudGen Firewalls lead to massive cost reductions. Rettig ICC was able to cut their line costs in half. Despite adding more branches to the network infrastructure, the bandwidth did not need to be expanded. Aditionally, the total number of network failures could be reduced significantly.

The intuitive configuration of Barracuda CloudGen Firewalls and the Barracuda Firewall Control Center’s effortless, centrally managed updating procedures proofed to be a great time-safer for the IT department. These solutions also helped to reduce IT overheads.

Even though Rettig ICC is currently not considering transitioning to the public cloud, a future adoption is still possible. Rettig ICC finds it reassuring that Barracuda also offers its solutions in the cloud. Making their investment future-proof.

"With Barracuda providing CloudGen Firewalls, including secure SD-WAN for all major public cloud providers we are well positioned for future expansion plans."

About the Barracuda CloudGen Firewall

Barracuda CloudGen Firewalls feature advanced security capabilities, including integrated Intrusion Prevention (IPS), URL filtering and antivirus to identify and block evasion attempts that would trick traditional systems. Barracuda’s security extends beyond a network to Barracuda’s Advanced Threat Protection (ATP) cloud for both statistical and sandboxing analysis of zero-day and targeted threats that routinely bypass signature-based IPS and antivirus engines.
