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

"The encryption and the security standards are valuable."

"Their GPS possibilities and the security that it has, especially the SD-WAN functionality, is very good."

"One of the most important parts is, there is auto-upgrade of the hardware every fourth year."

"Single sign-on is also good. If you are accessing your corporate firewall from your home, during that time there is integration with AD. You can use your AD password to access your SSL VPN. It's not like if you buy an additional SSL VPN... You can directly integrate with your AD. If you change your password on the AD side, your client-to-VPN password also gets changed. You can integrate all your passwords from a single console. It's not like admin has to change your password, it's a single sign-on."

"They have very good security."

"We use Barracuda NG Firewall as a border firewall. We trough it to control all in/out Internet traffic."

"This solution has allowed us to use multiple commodity internet connections at our locations, added greater control of internet usage, and enhanced security."

"I think Barracuda CloudGen Firewall is one of the most advanced firewall platforms. I also like that it's easy to get top-level support right away. You get that security, and if you make a mistake, it doesn't break."

More Barracuda CloudGen Firewall pros

"The most valuable features of Nozomi Networks are the visibility of OT protocols and the versatility in finding the details of the assets feeding the tool."

"Nozomi Networks is an easy-to-use and powerful tool."

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

"The feature I like best is its stability."

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

"Provides security for our operational technology environment for OT and IoT."

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

"Nozomi Networks has positively impacted our organization by giving us more visibility into our OT network, so now we know what is happening in our OT network and we can find things which were never there before and which we did not know before."

More Nozomi Networks pros

Cons

"We would like to see a solution that is focused on container deployment, which is very important right now."

"Another problem with Barracuda, in my experience, is the appliance lifetime."

"The solution could be improved with visibility into the traffic about what's happening at a given time."

"I have experienced reliability issues sometimes after an update of the AI engine, but these issues are very temporary and minor."

"There could be improvements in licensing."

"A rule for email announcements, when configured hits occur, would be a great improvement for a more efficient experience."

"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."

"Its interface could be better."

More Barracuda CloudGen Firewall cons

"Regarding the functionality of Nozomi Networks, the query syntax is very complicated. The syntax of the queries is very complex, so sometimes you will not get what you want."

"Nozomi Networks can be improved in many points. First of all, reduce the cost. That is really important because many companies are not so huge and many companies cannot acquire this kind of licensing."

"I chose eight out of ten because their customer services are something lacking."

"We have faced downtimes, crashes, or performance issues with certain implementations."

"Creating custom queries is time-consuming."

"Nozomi Networks should improve its pricing."

"Nozomi Networks pricing is very high."

"In terms of improvements for Nozomi Networks, I believe clients have mentioned experiencing alert fatigue due to the high volume of notifications once they install the system in a previously unmonitored OT environment."

More Nozomi Networks cons

Pricing and Cost Advice

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

"The solution's price is reasonable."

"It's not the most expensive, but it's certainly not cheap."

"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."

"When the corporation purchases something, it follows a request-for-proposal process and the best price wins. So, I think Barracuda CloudGen Firewall is reasonably priced, though I’m not sure of the exact amount"

"The platform is inexpensive compared to other vendors."

"The pricing is very cheap compared to Cisco ASA, which we used before, and compared to Palo Alto Networks and Fortinet. Barracuda has different solutions for different people. So for my SMB-level infrastructure, Barracuda has given me a proper solution that is half of the price of Palo Alto or Fortinet."

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

More Barracuda CloudGen Firewall pricing and cost advice

"The solution's pricing is good and cheaper than that of Claroty."

"I have not seen any competition in terms of pricing, and it is quite reasonable."
