Offers robust analytics and seamless cloud integration with minor room for user interface improvement
The Microsoft support and the analytics are what I appreciate about Azure Web Application Firewall. It integrates effectively with things such as Sentinel and Defender for Cloud, so mostly it's the analytics and now the AI capabilities that have been introduced with Co-pilot. It helps when looking for threats. It reduces issues significantly because the filtering capabilities are high. Given that it's a cloud solution, we have very minimal downtime, especially because we have Microsoft support. On a scale of one to 10, I would give it an eight.

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.

Cons

"The pricing needs improvement, and I think for beginners it will be a little bit complicated, so the ease of use could be enhanced."
"Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead."
"In Brazil, we have some problems with the phone service that affect our connection with the cloud. However, it isn't common."
"Azure WAF should not be deployed in the middle of the traffic."
"There is a need to be able to configure the solution more."
"From a reporting perspective, they could do more there."
"I would say that Azure's customer service is not that good...I am not very happy with the support offered."
"From my point of view, there is no need for improvement."
"The primary area that needs improvement is compatibility with the latest IoT technologies."
"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 documentation for Microsoft Defender for IoT is lacking. There are no clear steps or guidance, and updates are frequent, which adds to the confusion."
"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 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."
 

Pricing and Cost Advice

"We have an enterprise agreement with Microsoft and the pricing is good."
"The price is reasonable. It is approximately $2,000 US per month."
"I give the pricing a nine out of ten."
"Azure WAF has price advantages over other WAF solutions. The pricing model is flexible because you pay on a scale based on the level of protection you need."
"The price of the solution depends on your architecture and how you manage it. You can control the cost in Azure quite well. The costs do not directly correlate to expenses in the features we are using."
"The price is for this solution is fair and there is a license needed."
