Rashedul Khan - PeerSpot reviewer
Seamless integration enhances security while reducing manual effort
We didn't use TLS termination or malware filtering extensively because those are part of the premium features for Azure Firewall. At this point, I cannot see much improvement needed for Azure Firewall, because it served my purpose; having used it for four months, I am satisfied with the features and performance that I needed for my project. Features that integrate AI functionalities into Azure Firewall could be added, which can also address costing issues. We have features that we require, but they are in the premium offerings. If some features with limitations, for example, limited users, could be made available in the standard Azure Firewall, it would be easier for beginners choosing Azure Firewall at a very first level to test those features without needing to upgrade to premium.

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

"We use the solution for application and server deployment."
"I like that you can deploy the policies separately from the firewall."
"We secure the entry point to the virtual data center with the firewall."
"With Azure products, customer support is really good."
"The solution is very stable. When comparing it to other environments, it's actually quite impressive."
"The solution has many useful features. For example, the solution allows users to create virtual IP addresses."
"The firewall policy control, URL content control, and antivirus are all the most valuable aspects. Threat prevention is as well quite good."
"The feature that I have found the most valuable is the control over the network permissions and the network."
"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."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
 

Cons

"This solution is not mature when it comes to handling perimeter traffic like internet browsing."
"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."
"Azure Firewall has limited visibility for IDPS, no TLS inspection, no app ID, no user ID, no content ID, no device ID. There is no antivirus or anti-spyware. Azure Firewall doesn't scan traffic for malware unless it triggers an IDPS signature. There is no sandbox or machine learning functionality, meaning we are not protected from Zero-day threats. There is no DNS security and limited web categories."
"One thing that would help engineers adopt it better is the documentation."
"The tool needs to improve the onboarding and transition process for on-prem users."
"It has fewer features than you can get from other firewalls, like anti-spam and anti-phishing. Those kinds of things are not included. It only includes IDS and IDB."
"It would be nice to be able to create groupings for servers and offer groups of IP addresses."
"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."
"Further integration across different Microsoft products would be an improvement."
 

Pricing and Cost Advice

"Azure Firewall comes with Azure native services. We did not buy any kind of license for it. Whether you have a free subscription or a pay-as-you-go model, you can deploy the Azure Firewall service... The amount that you use will determine how much you pay."
"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 Firewall is quite an expensive product."
"Before choosing this solution, we evaluated others, and we found this to be the most cost-effective."
"The solution is cheaper than other brands. My company has an enterprise contract and we finally got a good price with Azure."
"The total cost of ownership is much less than Palo Alto, Cisco, or any other brand."
"The pricing of Azure Firewall is pay-as-you-go. Fortinet also has a pay-as-you-go model, but Azure's pricing is higher and, with FortiGate, you also have the license."
"I rate the product pricing a five out of ten."
