Case Study: Stadtwerke Villingen-Schwenningen achieves secure regional utility supply and advances carbon neutrality with Barracuda Networks

Barracuda enables Stadtwerke VillingenSchwenningen GmbH to secure the region’s supply of electricity, heat, gas, and water while pursuing climate neutrality

Stadtwerke Villingen‑Schwenningen (SVS) is the public utility serving the Black Forest region with electricity, heat, gas, and water. Facing strict KRITIS requirements, SVS needed to reliably and securely connect hundreds of decentralized plants, switchgear, heating and gas stations, and waterworks to its 24/7 operations and control center, while protecting online services, offices, and data centers and ensuring rapid recovery from ransomware — all with qualified on‑site managed support.

With long‑time partner cx‑solutions, Barracuda products were deployed as a single, holistic solution: dozens of Secure Connector appliances with always‑on VPN, CloudGen Firewalls, Web Application Firewall, Email Security, Barracuda Backup, and 24/7 managed monitoring. The result is KRITIS‑compliant, resilient connectivity and protection that keeps critical services available, enables fast recovery from incidents, and supports SVS’s rollout of dozens of decentralized clean‑energy plants on the path to carbon neutrality.
