AnvarSadique - PeerSpot reviewer
Easy setup and effective traffic routing enhance security
In terms of improvements, I think the price could be a concern as Azure ( /products/microsoft-azure-reviews ) services are often more expensive compared to other firewalls. However, the functional aspects of Azure Firewall met our needs. While I found the interface not particularly user-friendly, this is a common issue across vendors.
AndyChan3 - PeerSpot reviewer
Enhanced visibility and exposes vulnerabilities but needs more integration
I am currently in the pilot stage of implementing Microsoft External Attack Surface Management (EASM). My organization is transitioning to a comprehensive track of Microsoft solutions, and we will move to full-scale production in another year, maybe Microsoft External Attack Surface Management…

Quotes from Members

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

Pros

"Azure Firewall integrates well with multiple platforms."
"The features of Azure Firewall that I find most valuable include DNS inspection, forward proxy, and security, particularly on the edge."
"The solution should be capable of self-scaling, which is one of the features we like about it."
"I find the solution to be very stable, and would rate it a ten out of ten in terms of stability."
"The solution has FQDN integration."
"The firewall policy control, URL content control, and antivirus are all the most valuable aspects. Threat prevention is as well quite good."
"I think that one of the best features is definitely the premium version, along with the IDPs in terms of the intrusion detection and prevention system."
"Azure's cost-effectiveness is its major advantage."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"It seems to be better at protecting from cyberattacks."
 

Cons

"You have to have a defined IP range within your network to associate it with your network. The problem is you have to plan ahead of time if you expect to use the firewall in the future so that you don't have to reconfigure your subnets or that specific IP range. Other than that, I don't any issues. I use it for basic configuration for a single application, so I really don't try to leverage it for multiple applications where I might find some complexity or challenges."
"An Azure firewall is not a real firewall."
"I would like the premium and standard features to be available on the basic package. Additionally, it lacks some functionalities when compared to competitors like Check Point and Fortinet, such as WAF or load balancing."
"For larger enterprises, they need to adjust the scalability."
"It needs a lot of improvement, especially on intruder detection. They are working hard on that."
"There are a number of things that need to be simplified, but it's mostly costs. It needs to be simplified because it's pretty expensive."
"Azure Firewall definitely needs a broader feature base. It should be able to go all the way up to layer 7 when looking at applications and things like that."
"It would be much easier if the on-premises, firewall rules, had some kind of export-import possibility in place, which is not the case right now."
"Further integration across different Microsoft products would be an improvement."
"The integration is not as seamless compared to competitors like Palo Alto."
"With Microsoft, support is always crazy, it's not easy to get support."
 

Pricing and Cost Advice

"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."
"The total cost of ownership is much less than Palo Alto, Cisco, or any other brand."
"The solution is cheaper than other brands. My company has an enterprise contract and we finally got a good price with Azure."
"Before choosing this solution, we evaluated others, and we found this to be the most cost-effective."
"Azure Firewall is more expensive. If Microsoft can make Azure Firewall cheaper, I can see that all clients will think of using it. One client used FortiGate because it is much cheaper. Some clients ask me for Cisco, but in the cloud estimate, I found its cost is the same as Azure Firewall."
"Azure Firewalls operate on a pay-as-you-go model, similar to cloud services."
"Azure Firewall is quite an expensive product."
"Azure Firewall is expensive."
