Security management has improved with centralized threat detection and automation
I have been using Azure actively in my company, engaging with various technologies such as Azure SQL Server, virtual machines, and other cloud-dependent development scenarios. To secure the environment, we sometimes utilize Azure Firewall Manager. We needed to manage different individual firewalls…

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

"Azure Firewall Manager centralizes network security management with a hub and spoke architecture."
"Azure Firewall Manager centralizes network security management with a hub and spoke architecture."
"It is easy to install and does not require any plugins for your browser."
"The tool's support is good."
"The most valuable feature of Azure Firewall Manager is the testing and configuration."
"The solution has improved our organization with its firewall."
"The solution is very easy to set up."
"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."
"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."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"The technical support is good and quick to resolve issues."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"Defender for Office 365 has helped eliminate having to look at multiple dashboards and that is the aspect I like most about it. It is simpler, effective, and convenient. The users like the process efficiency."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
 

Cons

"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 solution can improve the integration with open-source tools."
"The price is okay. This said, the solution is certainly expensive in comparison with other cloud services."
"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 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."
"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."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"The certification training for Defender for 365 needs to be deeper and incorporate Sentinel. I took all the security courses except one, and Sentinel isn't included."
"The phishing and spam filters could use some improvement."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"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."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
 

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."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"The license is expensive because the cost is based on the number of users."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"It's a user-base subscription."
"The pricing has become expensive."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
