Sikkander  Batcha - PeerSpot reviewer
Has managed traffic effectively but lacks visibility and advanced control features
Azure Firewall is typically behind other vendor firewalls because we don't see what kind of traffic is traveling through it. That is one drawback. The main drawback is that we need log support from Azure Firewall, which can be quite costly. There is no login feature in Azure Firewall because only the IAM feature is available in the Azure site; we manage it only through the Azure portal, not through any other portal. Other vendors, such as Palo Alto, provide GUI or CLI interfaces to manage their firewalls, whereas we only manage Azure Firewall through the Azure portal. In the future, I would like to see additional features in Azure Firewall Manager to make it more competitive, such as technologies like App-ID and User-ID that Palo Alto has. Azure Firewall currently only allows traffic based on layer four and sometimes layer seven, so they need to improve in those areas compared to other vendors.

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.

Quotes from Members

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

Pros

"It is easy to install and does not require any plugins for your browser."
"The solution has improved our organization with its firewall."
"From a traffic management perspective, it's a good firewall because it's automatically scalable based on the traffic availability."
"From a traffic management perspective, it's a good firewall because it's automatically scalable based on the traffic availability."
"The solution is very easy to set up."
"We are utilizing Azure Entra ID for group labeling, so Active Directory, or now it is Entra ID, securing our application for everyone who accesses it, and Azure Firewall Manager is definitely securing our projects and all its features are fine."
"The most valuable feature of Azure Firewall Manager is the testing and configuration."
"The best feature of Azure Firewall Manager is that it is easy to maintain and configure."
"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. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."
"The DLP feature of Microsoft Defender for Office 365 is valuable, and we also use the DLP feature for email real-time detection."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."
"One of the best features of the tool is its capability to aggregate insights from different workloads, basically from the Office 365 and endpoints part."
"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
 

Cons

"Azure charges for many aspects including scaling, automated scaling deployment, and traffic management, which leads to higher costs."
"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."
"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."
"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 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."
"Azure charges for many aspects including scaling, automated scaling deployment, and traffic management, which leads to higher costs."
"The solution can improve the integration with open-source tools."
"The tool's security features need to improve. It needs also to include a monitoring system for logs. It is also complicated to find a query on the Azure firewall."
"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"We need to be able to whitelist data at the backend."
"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"I think that Microsoft Defender for Office 365 could be improved if it could use VirusTotal to compare the programs or anything that I download."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"I'd like some additional features any product can give me to protect our environment in a better way."
"The XDR dashboard has room for improvement."
"Several simulation options are available within 365, and the phishing simulation could be better."
 

Pricing and Cost Advice

"The price of the solution is reasonable but it is reasonable for the features."
"The solution is certainly expensive in comparison with other cloud services."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"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."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The pricing is normal. Considering its popularity, it's not overpriced."
"The product is expensive."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
