Manages multiple firewalls effortlessly but faces challenges with cost efficiency
Azure Firewall Manager is good most of the time, but it could be improved regarding cost. The cost is a significant concern because we are in a region where the dollar is not our default currency, and converting to dollars makes it very expensive. Microsoft should calculate and show the products in local currencies, such as PKR or Bangladesh currency, and also introduce Indian currency similarly for Pakistan. The technical support could be improved. When a resource is assigned, that resource should follow the ticket and respond swiftly, including sending an email to inform me that an agent has been assigned. I still find myself waiting for an agent to connect with me and resolve my issues. I have not been integrating Azure Firewall Manager with Azure Virtual WAN.

Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"The most valuable feature is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."
"Scalability-wise, I do not think there are any issues so far."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks.

Cons

"There should be a simple one-click deployment for a firewall, rather than a set of setup instructions that include steps such as the DNS configuration, et cetera."
"The configuration and settings require substantial time for learning, particularly for new users."
"The configuration and settings require substantial time for learning, particularly for new users. Improvements in ease of configuration would benefit users significantly."
"The price is okay. This said, the solution is certainly expensive in comparison with other cloud services."
"For Azure Firewall Manager, the learning curve for new people is a bit challenging, but the integration should be more straightforward for configuring a centralized system."
"The cost is a significant concern because we are in a region where the dollar is not our default currency, and converting to dollars makes it very expensive."
"The solution can improve the integration with open-source tools."
"We could do only one-way NAT-ing, where the traffic comes from outside to internal, to Azure, which is fine. However, when we actually do NAT-ed traffic to hit the firewall, that way is not working."
"The UI needs to be more user-friendly."
"The GUI is sometimes slow to fetch the device report and could be improved."

"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."
 

Pricing and Cost Advice

"The solution is certainly expensive in comparison with other cloud services."
"The price of the solution is reasonable but it is reasonable for the features."
"The product is expensive."
"It's a user-base subscription."
"The license is expensive because the cost is based on the number of users."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"The pricing has become expensive."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
