Network monitoring provides comprehensive analytics while the interface requires further development

The quality of Azure Network Watcher is quite good in terms of the in-depth analysis you can create from these matrices. There are other monitoring tools such as New Relic, AppDynamics, and Dynatrace which provide very detailed network tracing. Cloud providers such as Azure or AWS do not have that kind of GUI-based capability at this point, but using PowerShell or Python, you can develop it yourself. From the GUI perspective, it still needs to evolve in terms of quality and standard, though overall, it is quite good for troubleshooting. Regarding areas for improvement, when comparing to other network tools beyond Azure Monitor or Azure Network Watcher, those tools can identify single failed packets. This level of granularity is not currently possible with cloud providers as they only go to a certain level rather than the granular level needed for deep troubleshooting, though they do provide hints with available matrices.

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 stability is very good. I rate it a ten out of ten."

"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 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."

"The solution is good for monitoring device behavior."

"It provides good visibility."

"We use the solution to monitor network services. It helps to capture any network issues."

"Azure Network Watcher provides valuable features based on your specific requirements and use cases, helping you monitor network bandwidth, throughput, data flow consumption, and control costs by giving insight into egress and ingress traffic, total input and output operations, bandwidth, and threats through IP identification."

More Azure Network Watcher pros

"The tool's most valuable feature is its scripts. These scripts prove beneficial when security features may obscure or block connections. Nmap helps identify vulnerabilities across different systems, including web servers and various server types."

"The initial setup was simple."

"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 real-time reporting feature of Nmap is particularly valuable. It generates detailed reports on the source and destination IP addresses, the protocols used, and the types of traffic."

"From a functionality standpoint, it's robust and straightforward to comprehend."

"Nmap has a powerful command line tool and a set of diagnostic features."

"It helps us secure the network infrastructure."

"The solution detects the operating systems, which makes testing the software much easier before making the payload."

More Nmap pros

Cons

"Azure Network Watcher needs to have better documentation and it needs to capture information accurately."

"Lacks sufficient security features."

"There are some occasional downtimes, but these were based on Azure-specific issues."

"Technical support from Microsoft needs significant improvement compared to other product vendors."

"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 initial setup and initial learning curve could be improved to be easier."

"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."

More Azure Network Watcher cons

"Nmap major operates through the CLI; there's no GUI component, and that's where the challenge is."

"The solution should increase the number of features under a free license."

"There could be a specific option to check non-pingable endpoints for the product."

"There are concerns with the stability of the product, making it an area where improvements are required."

"They should deliver Playtech's username and password."

"Nmap needs to improve its scanning speed."

"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 tool's license limits the number of scans it can perform. Improving the license model could benefit customers by allowing more scans for compliance and other purposes."

More Nmap cons

Pricing and Cost Advice

"Price-wise, I have no information on how much Azure Network Watcher costs."

"Azure Network Watcher is a little bit expensive."

"The pricing is good. It's not too expensive."

"The price of the solution is reasonable."

"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."

"It's an open-source solution. Commerically, only the support service is available."

"The product's pricing is fine. The licensing options for Nmap include perpetual licenses and volume-based licenses. For perpetual licenses, once you purchase it, there's no need to invest in renewals. And for volume-based licenses, enterprise companies can use it multiple times based on the number of users or devices they need to scan. It's a pay-as-you-go model, similar to how you pay for what you use."

"The solution is free of cost, but there are specific services that we have to buy."

"Nmap is an open-source and free product."

"The solution is open source so it is free."

"I am using the free version of Nmap."

Microsoft

Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).
