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.

Centralized security management has protected our hybrid network and supports secure remote work
Overall, Barracuda CloudGen Firewall is very effective, but there is always room for improvement. One area that could be enhanced is the user interface, making it slightly more intuitive for new users. Additionally, advanced reporting and analytics could be more customized to provide deeper insights. Despite this, the firewall performs reliably and meets most of our organizational needs. One additional improvement that could enhance the experience is faster troubleshooting support or more detailed guided documentation for complex configurations. While the firewall is reliable, having more step-by-step tutorials or video guidance could help new users set up and optimize. Overall, the enhancement would make the platform even more user-friendly without affecting its current strong performance.

Effective asset management improves OT security by quantifying risks and identifying unauthorized communications
Nozomi Networks currently offers add-ons, such as ARP agents, that can be installed on machines to expand the information we receive from sensors. However, these are part of a licensing structure, which can be costly. It would be very helpful if these agents were available free of charge. The solution itself has no major problems, but this is a feature request I would make for improvement.

More Nozomi Networks pros
 

Cons

"When you login from some sources, there is no feature in this box which can log you out after a certain timeout."
"It's a little bit complex in terms of handling. If you implement a change, there is a specific point where you have to commit it. It's not like you just push a button and it's always committed. If you don't know to check whether your commit command has been executed or not... that is something Barracuda needs to work on."
"If you experience an attack it can take a very long time to find a solution."
"The interface of Barracuda CloudGen Firewall is not as user-friendly as others."
"If you have another brand of VPN where you have to put an SSL VPN between two devices, Barracuda doesn't support that at a certain point. You can't actually build the VPN between Barracuda and a different device of a different brand."
"The administration UI could be better. It should also have better application detection policies."
"I would like to see a more user-friendly dashboard and an easier interface."
"Command line could be more user friendly."
More Barracuda CloudGen Firewall cons
"I believe there is room for improvement regarding on-premises AI."
"The solution should include an integration library."
"It should support more programmable logic controllers (PLCs)."
"I would like more customizable options for configurations."
"Nozomi Networks should improve its pricing."
"Nozomi Networks currently offers add-ons, such as ARP agents, that can be installed on machines to expand the information we receive from sensors. However, these are part of a licensing structure, which can be costly."
"Proof of concept could be improved. It could be more tangible to the customer and the end users to have a video presentation or something like that."
"Creating custom queries is time-consuming."
 

Pricing and Cost Advice

"The product is a bit cheaper than some solutions."
"It is a product with a very transparent model of licensing. In the sense of hidden expenses, they do not exist with this model. ​"
"In general, it tends to be cheaper than most solutions."
"It's not the most expensive, but it's certainly not cheap."
"The 600 series is about USD $10,000 a year and the 80 is USD $400 a year."
"We pay around 150 to 200 Euros per year and there are no additional costs."
"It would be nice if the pricing and licensing offered for less."
"Purchasing through AWS Marketplace was good. We did it because it was easy."
