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.

Security monitoring has become proactive and threat hunting is now faster and more precise
The best features of Microsoft Defender for IoT are that it is easy to find where the intruder is and easy to capture and hunt intruders. When I need to send a full scan for a device, it is straightforward. I have worked with Symantec, which is an antivirus, and McAfee, where I send full scans in a similar way to how I do it in Azure Defender, and it is equally easy. I can take actions with the device, such as disconnecting it, turning it off, or sending an alarm. The integration with Azure Defender and Azure Sentinel is seamless because they are from the same company. They capture intruders, viruses, worms, and everything else easily, and I can fix problems quickly. I use the network visibility features daily to manage connected assets. Currently, I am closing a case with Mutual Asesorías where they have a computer with intruders attempting to force brute capture the password. I can see how the intruder tried to do this, and my work involves closing the IP origin in this case.

Quotes from Members

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

Pros

"We use Barracuda NG Firewall as a border firewall. We trough it to control all in/out Internet traffic."
"We enjoy the reduction in terms of labor."
"The features I find most valuable is the VPN and the fact that we can apply our policies to the program."
"Barracuda is very prompt at blocking any new spam which comes out."
"It's great for handling complex items."
"I like the identity fire walling, malware protection and application control features."
"Barracuda CloudGen Firewall has positively impacted my organization by increasing the level of network protection against threats from twenty percent to forty-five percent."
"It's really a good and stable product; I have worked with multiple firewall products and I can say that this is really very robust, good hardware, and it's also good on the cloud side."
"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."
"The graphics and analysis in Microsoft Defender for IoT are very representative."
"I believe it is best suited for cloud services and is unmatched by other cloud security solutions."
"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."
"Mainly, it is manageable and integrates with other Microsoft products, which is crucial for me."
"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."
"It is manageable and integrates with other Microsoft products, which is crucial for me."
"The best features of Microsoft Defender for IoT are that it is easy to find where the intruder is and easy to capture and hunt intruders."
 

Cons

"The interface should be more user-friendly and it should be easier to configure."
"The unit seems to be handling our 150MB pipe okay, but logger refresh leaves a bit to be desired."
"One of the main challenges that we face with Barracuda CloudGen Firewall is that the URL filtering and application control license are not perpetual and need to be renewed every year, so it can be a bit expensive."
"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."
"To start working with spam, it takes a while because the product has to see that multiple emails are coming in with all the spam. If it could reduce that amount of time, then we would reduce the amount of users who are receiving spam."
"The interface of Barracuda CloudGen Firewall is not as user-friendly as others. It is a bit complicated and could be improved."
"It would be better if they had a trace and trap feature. It's hard for me to say anything bad about Barracuda. This is because we had a firewall go down in the town of Kirkland Lake, and it was a blown-out port, and they had an instant replacement."
"There could be improvements in licensing. Some licensing aspects are challenging; for example, if you're using an active-passive setup, you have to license both firewalls."
"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."
"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."
"Microsoft Defender for IoT is not scalable. If you want to monitor another industrial network, you need an additional server, making it less scalable."
"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 primary area that needs improvement is compatibility with the latest IoT technologies."
"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."
"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."
 

Pricing and Cost Advice

"In general, it tends to be cheaper than most solutions."
"Pricing and licensing are fine. It's worth the value because every four years, if I buy any other product, I have to replace my hardware. But with Barracuda I get a free hardware upgrade. Today I'm using Xbox. After four years I can take another Xbox or a Ybox."
"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 solution's price is reasonable."
"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 product is a bit cheaper than some solutions."
"It would be nice if the pricing and licensing offered for less."
"​We evaluated a lot of different options. We concluded that Barracuda NG Firewall provided the most features for an exemplary price. ​"
