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

"Since implementing the Barracuda CloudGen Firewall, we've seen significant benefits, particularly in stopping a lot of unnecessary or dangerous emails. One key feature we value is the ability to train the solution with emails categorized as threats, giving it a learning capacity."

"The most valuable features are SD-WAN, URL filtering, IPS, and virus scanning."

"It can now integrate with Barracuda's XDR."

"TINA (Transport Independent Network Architecture) VPN features - Allows automatic VPN configuration with little or no input from the tech. Drag and drop lines between Barracuda units and the VPN is built automatically."

"The solution is stable."

"The interface is very user-friendly and it is quite easy to use."

"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."

"Easy integration with some other systems like LDAP or Active Directory to manage other permissions and the division of external access and internal access."

More Barracuda CloudGen Firewall pros

"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."

"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."

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

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

"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."

Cons

"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."

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

"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."

"When you login from some sources, there is no feature in this box which can log you out after a certain timeout."

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

"The initial setup is a bit complex."

"If you experience an attack it can take a very long time to find a solution."

"I would like to see the connection improved."

More Barracuda CloudGen Firewall cons

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

"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."

"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."

"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."

Pricing and Cost Advice

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

"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."

"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"

"Pricing is good. Licensing is pretty much automatic if using Control Center."

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

"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."

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

"My advice is to try and evaluate it (Barracuda offers a trial period of one month)."
