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 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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Scalability is good - there are many different models and you can pretty much go from small shop to giant ISP."

"The most valuable feature for us is the ability to offer firewall support to our clients."

"The features I find most valuable is the VPN and the fact that we can apply our policies to the program."

"As stated, I’ve worked with firewalls from different vendors, also in quite large environments, but they are no match for the Barracuda NG Firewall, not by a long shot."

"The technical support from Barracuda is very good. I would rate it nine out of ten."

"The drag and drop features of VPN are really convenient to be configured, and the VPN tunnel provides a secure environment in the organization."

"Barracuda is very prompt at blocking any new spam which comes out."

"Scalability is good; the company wants to be able to handle large customers."

More Barracuda CloudGen Firewall pros

"Nozomi Networks has the best AI-based detection and intrusion detection solution, as it is very robust, easy to deploy, and easy to use with a very user-friendly GUI and good support in terms of product and after-sales support."

"This is a good product and I definitely recommend it."

"I chose Nozomi because it is far ahead of other competitors, like Curator and Elastic."

"The network visualization feature of Nozomi impacts security operations positively."

"I believe it is the best."

"The best feature of Nozomi Networks is that it has built OT-oriented protocols such as OPC UA, DNP3, Modbus, and Siemens S7, and for these protocols, Nozomi Networks identifies them very perfectly."

"It brings visibility into the OT environment because most of the enterprises only have methods to check their IT environment."

"The tool's visibility is good. We can see the traffic flow."

More Nozomi Networks pros

Cons

"Can be underpowered if you choose to use all available add-on features. Just be careful when sizing your unit. Make sure you take into account what features you will be turning on, and work with your sales rep to get the model that can handle that load."

"Technical support could be more reliable and more professional."

"Sometimes we have a need for detailed reports. Barracuda NG Firewall does not have a reports module and uses a satellite application (Barracuda NG Firewall Report Creator)."

"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."

"Command line could be more user friendly."

"Nothing much except some little buggy issue sometimes, such as unable to login using the default login when out-of-box and will required factory reset once again."

"There is room for improvement in terms of response time and first-level support quality."

"I was a long-time strong fan of this product, but unfortunately, I will change the vendor for another one."

More Barracuda CloudGen Firewall cons

"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."

"I believe there is room for improvement regarding on-premises AI."

"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."

"I would like more customizable options for configurations."

"The solution should include an integration library."

"Creating custom queries is time-consuming."

"It should support more programmable logic controllers (PLCs)."

"On the negative side, I believe their AI, which is IQ, could be more improved."

More Nozomi Networks cons

Pricing and Cost Advice

"It is a product with a very transparent model of licensing. In the sense of hidden expenses, they do not exist with this model. "

"The product is a bit cheaper than some solutions."

"In general, it tends to be cheaper than most solutions."

"Its licensing is on a yearly basis. There is an upfront purchase price, and there is also an annual maintenance fee. There are no additional fees."

"The solution costs more than 800 Euros to purchase an F18, which is an entry model, and then another 500 Euros for instant replacement, and 500 Euros for energized updates. The total package would be around 1,900 Euros for five years license and all updates for an entry model."

"We evaluated a lot of different options. We concluded that Barracuda NG Firewall provided the most features for an exemplary price. "

"The 600 series is about USD $10,000 a year and the 80 is USD $400 a year."

"It would be nice if the pricing and licensing offered for less."
