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 network monitoring with identified documentation improvements needed

The documentation for Microsoft Defender for IoT is lacking. There are no clear steps or guidance, and updates are frequent, which adds to the confusion. More detailed documentation with video instructions for tasks would be helpful. The system capabilities are not well-documented either. Importing device names and maintaining a list can be cumbersome, as it requires manual input for a large number of devices. The backup and restore process is limited to GUI for backup but lacks a GUI for restore, though future updates might address this. Sentinel documentation is also poor, with limited guidance available.

Quotes from Members

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

Pros

"The product is foolproof. It has done everything that we have needed with the amount of email that we receive, and it handles it quite well."

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

"The most valuable features of Barracuda CloudGen Firewall include antivirus protection, anti-DDoS, and IPS."

"I wanted to go to a software-defined WAN and in Barracuda they have a specific protocol called TINA (Transport Independent Network Architecture). You can create a master policy over the internet and it allows you to do Quality of Services on top of it. That is really helpful for me."

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

"If an employee tries to get or move a file that is not permitted to them - for example if he wants to copy it to a USB - he will not have the right to do that, because Barracuda manages who has the right to copy, and what you copy to a USB. The USB is encrypted with a specific code from Barracuda and will only be decrypted into any other laptop in the company if they allow it to see it."

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

"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

"As a cybersecurity consultant, the best part of Microsoft Defender for IoT is the capability to integrate with other tools such as Microsoft Sentinel and receive real-time alerts from the product."

"I believe it is best suited for cloud services and is unmatched by other cloud security solutions."

"The graphics and analysis in Microsoft Defender for IoT are very representative."

"It is manageable and integrates with other Microsoft products, which is crucial for me."

"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."

"Mainly, it is manageable and integrates with other Microsoft products, which is crucial for me."

"Some advantages of Microsoft Defender for IoT are that it's easy to install on any OS, and you can create any custom use cases easily."

Cons

"There should be improvements in the management aspect of the firewall. Specifically, it would be beneficial to merge the existing application policy with the main policy into a single unified policy to improve manageability."

"The interface of Barracuda CloudGen Firewall is not as user-friendly as others. It is a bit complicated and could be improved."

"The interface should be more user-friendly and it should be easier to configure."

"The technical manuals, at times, have images that don't match the actual screens and are not always as clear as they could be on the configuration."

"The analytics are weak."

"The administration UI could be better. It should also have better application detection policies."

"However, the solution isn’t perfect. It sometimes lets through emails incorrectlycategorized as safe but malicious. I believe the tool could be improved by incorporating artificial intelligence to enhance its email analysis capabilities, though I’m unsure if this feature is currently available."

"The biggest downside is that it is quite an expensive product."

More Barracuda CloudGen Firewall cons

"The primary area that needs improvement is compatibility with the latest IoT technologies."

"Microsoft Defender for IoT is not scalable. If you want to monitor another industrial network, you need an additional server, making it less scalable."

"The only improvement I see is that some detection explanations are vaguely provided by Microsoft, resulting in generic IoT detections that alert me to an issue yet don't specify what's wrong."

"There are a few limitations with Microsoft Defender for IoT. We raised concerns with the product team because they don't capture all the information regarding command execution or processes executed on certain endpoints."

"The documentation for Microsoft Defender for IoT is lacking. There are no clear steps or guidance, and updates are frequent, which adds to the confusion."

"The only improvement I see is that some detection explanations are vaguely provided by Microsoft, resulting in generic IoT detections that alert me to an issue yet don't specify what's wrong."

"Customer service and support from Microsoft are costly. The execution by engineers is expensive, and the service is neither free nor toll-free, making it less accessible for customers."

Pricing and Cost Advice

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

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

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

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

"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."

"Purchasing through AWS Marketplace was good. We did it because it was easy."

"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"

"We pay around 150 to 200 Euros per year and there are no additional costs."
