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…

Scans the network and identifies vulnerabilities on each machine
Nmap is mostly helpful during compliance checks. We run the scanner to see how many devices are on our network and find vulnerabilities in those that aren't compliant. We also use it monthly to scan our network and identify devices that aren't connected properly. This helps us detect any issues related to the operating systems of these devices. The tool's most valuable feature is its vulnerability scanning. It allows us to scan a specific range of IP addresses and discover devices within that range. This makes it easy to identify devices and view their details. Port scanning is crucial for network management tasks. It helps us identify vulnerabilities by finding open ports that may be unused or misconfigured. This tool makes it easy to detect such issues. The OS detection feature is great. Unlike other tools, Nmap provides accurate information about asset vulnerabilities, helping us easily detect and address them. Using Nmap provides value to the company, especially during compliance audits. It helps generate reports on assets, updates on workstations, and insights into network activities and potential attacks. Additionally, Nmap detects vulnerabilities and provides port details, allowing us to close unused ports on the client machines.

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 stable."
"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."
"It provides good visibility."
"The solution is good for monitoring device behavior."
"I like the visibility."
"We use the solution to monitor network services. It helps to capture any network issues."
"The stability is very good. I rate it a ten out of ten."
"The most valuable features I have found are typology, visualization, and capture."
"Nmap is mostly helpful during compliance checks. We run the scanner to see how many devices are on our network and find vulnerabilities in those that aren't compliant. We also use it monthly to scan our network and identify devices that aren't connected properly. This helps us detect any issues related to the operating systems of these devices."
"The most valuable feature of the solution for security audits stems from the fact that it serves as a powerful tool with the ability to scan a large number of ports."
"Nmap's performance is great, and I've never noticed any issues in this respect. It really doesn't put a heavy load on the machine when using it."
"From a functionality standpoint, it's robust and straightforward to comprehend."
"The solution detects the operating systems, which makes testing the software much easier before making the payload."
"It helps us secure the network infrastructure."
"The best feature of Nmap is that it lets me see useful information about each endpoint in my entire network environment. For example, I can see every single connection of the network as well as each and every port."
"It is a very user-friendly product."
 

Cons

"Azure is good, however, the Fortinet GUI is more intuitive and I like it more than anything else."
"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."
"The initial setup and deployment could be improved to be simplified."
"Lacks sufficient security features."
"User experience could be improved."
"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."
"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 needs to have better documentation and it needs to capture information accurately."
"One of the drawbacks of the standard Nmap utility is that it does not come with a graphical user interface, unlike a number of other open-source alternatives such as Zenmap."
"The price is high and could be cheaper."
"There is room for improvement in the design, the GUI. It looks a bit odd. Maybe Nmap should improve it or add more widgets to make it more attractive, but the basic functionality is good and provides what we need."
"The solution's initial setup could be better."
"Since I started using Nmap, it has been completely based on the command prompt and I think it would help other users if they implemented a decent GUI as well."
"The challenge often lies in finding suitable courses and professional resources."
"It takes a bit of time to get familiar with the solution and its options."
"Customization is not very user-friendly in Nmap."
 

Pricing and Cost Advice

"The pricing is good. It's not too expensive."
"Azure Network Watcher is a little bit expensive."
"The price of the solution is reasonable."
"Price-wise, I have no information on how much Azure Network Watcher costs."
"It's an open-source product, and I haven't seen any premiums. Options are available for those who purchase, but for my use case, everything I need is available in the community and forums."
"Nmap is open source software, which suits us well because we are a manufacturing company and not an IT company, for example. If we were an IT company, we would probably need to pay for extra support or instead go for another software solution. But as it is, we don't have any need for high-end troubleshooting tools."
"The solution is open source so it is free."
"Nmap is an open-source and free product."
"I am using the free version of Nmap."
"The solution is free of cost, but there are specific services that we have to buy."
"Nmap is an open-source product. You don't need a license to install it."
"The solution is free of cost."
