Has enabled us to manage internal access securely but lacks accessible documentation for deeper integration
We haven't required any support, but overall, Microsoft support is good. Whenever we raise any concern, they are supporting us on time. Currently it is good. We are not a public-facing company; it is a retail company only, so that's why I don't think it is required. We don't have an e-commerce solution on Azure. For that, we are using a different stack for the e-commerce portal, so that is not in Azure. We are only using it for business applications, and I think L3 filtering in network security suffices for our problem currently. Regarding scalability for Azure Firewall, we don't need it here because the request to the application is internal. All are internal users. So there is not much request to get into the application, so scalability is not required for us in the current scenario.

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

"Among the most valuable features are the DDoS protection that protects your virtual machines, the threat intelligence, and traffic filtering."
"The most valuable features of Azure Firewall for me are its URL-based internet access control and DDoS protection for incoming traffic."
"We use the solution for application and server deployment."
"With Azure Firewall on the cloud, you just need to subscribe to the firewall, configure it, and it will help you protect your environment."
"The SIEM that Azure Firewall provides us is very robust."
"The most valuable feature is threat intelligence, which is based on filtering, can identify multiple threats, and easily detects them, with malware signatures updated automatically, which is helpful for new customers."
"We mostly use it as part of a hybrid cloud solution, and for clients with on-premises and cloud solutions, our recommendation is that Azure Firewall be used."
"The solution is very stable. When comparing it to other environments, it's actually quite impressive."
"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."
"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."
"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."
"I believe it is best suited for cloud services and is unmatched by other cloud security solutions."
"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

"I would appreciate it if Azure Firewall included built-in VPN capabilities."
"When we started deploying the solution, it was not a mature product at times."
"The product pricing could be more competitive."
"We find it's different implementing it region-to-region. It might help if it was universal across all regions."
"For large organizations, a third-party firewall would be an added advantage, because it would have more advanced features, things that are not in Azure Firewall."
"The interface could be improved, it's not very user friendly."
"The solution doesn't offer the same capabilities of Fortinet."
"Azure Firewall is an expensive solution. On a scale from one to ten, where one is not affordable, I would rate the price as a three."
"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."
"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."
"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 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."
"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

"The solution is cheaper than other brands. My company has an enterprise contract and we finally got a good price with Azure."
"It is expensive, especially with the premium functions. For one of the clients, it was very expensive. You have to use it more at an enterprise level, and there, it was not at an enterprise level. So, it was very costly, but security-wise, it was a very wise decision to use it that way."
"It is pay-as-you-go. So, you pay based on the usage. If I remember it well, there is a basic fee, and there is a traffic fee. It is not per month. It is per hour or something like that. It is not so expensive."
"Azure Firewalls operate on a pay-as-you-go model, similar to cloud services."
"The licensing module is good."
"Azure Firewall is expensive."
"Before choosing this solution, we evaluated others, and we found this to be the most cost-effective."
"Azure Firewall is quite an expensive product."
