Helpful database security, good support, and beneficial cloud-native application firewall
We are using Azure Network Watcher for remote access security The most valuable feature of Azure Network Watcher is the cloud-native application firewall. It is helpful for securing databases. Azure Network Watcher could improve by having other built-in applications. For example, an application…

Valuable reporting and alert system with room for PDF export improvements
The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Quotes from Members

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

Pros

"The solution is good for monitoring device behavior."
"The most valuable feature of Azure Network Watcher is using the gateways with the connections. The monitoring is useful for the logs and application insights into the data. The traffic filtering issues when it comes to deploying those applications are helpful."
"The most valuable feature of Azure Network Watcher is the cloud-native application firewall. It is helpful for securing databases."
"We use the solution to monitor network services. It helps to capture any network issues."
"What I like most about Azure Network Watcher is that it's focused more on the architecture. I also like that it has a packet capture feature that tells you how the packet travels and whether it's exiting Azure, etc."
"The most valuable features I have found are typology, visualization, and capture."
"It provides good visibility."
"I like the visibility."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"The application performance monitoring feature is valuable."
"Nagios Core is stable."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"We use the product to monitor server applications."
"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."
"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
 

Cons

"The solution could improve by limiting the need to clarify the logs. When the clarification is minimized, it is better for everyone involved."
"Azure Network Watcher could improve by having other built-in applications. For example, an application to log activities for in and outbound traffic."
"Azure is good, however, the Fortinet GUI is more intuitive and I like it more than anything else."
"Azure Network Watcher needs to have better documentation and it needs to capture information accurately."
"I would like to see in the future if we can troubleshoot as a firewall because it is equipment as a network player and some diagnostics."
"User experience could be improved."
"The initial setup and deployment could be improved to be simplified."
"I still use Wireshark and Azure Network Watcher to get the required data. My team captures the traffic from Azure Network Watcher, downloads it, then imports that traffic into Wireshark to get more details on the number of hits and replies, for example. If you can do that on Azure Network Watcher and have Wireshark built-in, that would make Azure Network Watcher better. If Azure Network Watcher has that functionality where you won't need a third-party tool to get what you need, that would be helpful. I'm also expecting more from Azure Network Watcher. It's more complex than knowing how the IP flows from its source to the destination. The tool also needs more open-source features, such as having some built-in Wireshark that improves monitoring for customers. Sometimes, you encounter a VPN tunnel, network, or routing issue, but finding out more about the blockage is challenging. Is it one hundred percent an Azure issue? Is it a peer issue? You don't get complete information from Azure Network Watcher, so you must use other tools and depend on your strategies to resolve a specific issue. If more features could be added in the next release of Azure Network Watcher, specifically ones you can find on open-source tools, then that would be a plus point for the tool."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"It is a bit slow due to latency."
"The alerting mechanism in Nagios Core could be improved."
"There is room for improvement in the graphics."
"t was a little hard to get our setup represented in the configuration."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
 

Pricing and Cost Advice

"Price-wise, I have no information on how much Azure Network Watcher costs."
"The price of the solution is reasonable."
"Azure Network Watcher is a little bit expensive."
