Executive SummaryUpdated on Feb 3, 2025

Barracuda CloudGen Firewall and Nozomi Networks compete in the cybersecurity sector. Barracuda appears to have the upper hand due to its scalability and comprehensive features tailored for large-scale management.

Features: Barracuda CloudGen Firewall offers TINA tunnels, real-time firewall logs, and advanced intrusion prevention systems, enabling efficient management of extensive networks. Its integration capabilities and ease of policy implementation enhance its compatibility with existing IT infrastructures. Nozomi Networks provides robust network visualization for OT environments, delivering valuable insights into asset management and security operations.

Room for Improvement: Barracuda CloudGen Firewall could enhance its configuration experience, improve IPv6 support, and refine reporting functions. The platform's interface can be complex, and certain add-on features may struggle if not appropriately sized. Nozomi Networks should address pricing structure improvements and offer more customizable options for configuration ease. Both platforms need to improve technical support documentation and address isolated bugs.

Ease of Deployment and Customer Service: Barracuda CloudGen Firewall supports on-premises, hybrid, and public cloud environments, noted for flexibility and strong customer service, although regional support may vary. Nozomi Networks also offers similar deployment settings, but experiences with support are more variable, indicating room for improvement in response strategies.

Pricing and ROI: Barracuda’s licensing model is transparent and cost-effective, offering an instant replacement program with free hardware upgrades after four years. Pricing is competitive, providing value for multi-location operations. Nozomi Networks offers reasonably priced solutions viewed as mid-range compared to similar platforms, emphasizing value through network monitoring and intrusion prevention. Users find good returns on investment for both products, but Barracuda's comprehensive features and support offer strong cost-benefit appeal for larger infrastructures.

Jennifer Bernice

Dotnet Developer at Kohl's

Centralized firewall management has saved time and improved network security across locations

Barracuda CloudGen Firewall could be improved as it has a very high learning curve. It is definitely not a one and done firewall, as a one and done firewall requires a lot of dedicated time to get the machine running the way you want. To improve Barracuda CloudGen Firewall, there should be a lot of tutorials and videos online to help new users. Multiple ways to configure for the same service or feature takes time to determine your customized build. In addition to previous points, the interface can sometimes be clunky when trying to determine how it is organized or arranged.

Comprehensive dashboards have enabled detailed asset visibility and proactive risk mitigation

On the negative side, I believe their AI, which is IQ, could be more improved. For example, when I export any data, there are only 50 columns available. What if there were more columns? Nozomi Networks does not provide that data, so I have to go to the query section. The AI is currently useful for writing queries in English that are converted into their coding language for queries. Sometimes it provides the correct data, and sometimes it does not understand the request. From my attempts, I would say 50 percent of the time it has given me the proper data, and 50 percent of the time it might need improvement. Every day or week, new threat intelligence and AI upgrades are being released for Vantage, and all those upgrades are being implemented. Things are getting better, but I believe there are areas of improvement.
