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.

Penetration testing has become efficient as I identify open ports and security risks with confidence

Nmap could potentially become a GUI and provide automatic reports with one-click downloads. For example, the report could show all the open ports for an IP address with a professionally formatted report. This is a far-fetched suggestion and not really required, but it could make the work a little better. On a scale of one to ten, I give Nmap a solid nine. I mean, how can you fix something that is not broken? Nmap is already the best, and I do not think there are any other features that can be added. Its job is reconnaissance, so I do not think there is more to add to it. However, if I get any ideas, I will let them know about this.

More Azure Network Watcher pros

"Nmap is free and should stay this way."

"The most important function, according to me, is the capability to use some arguments in the scanning. The solution's capability to go figure and do a deep dive, discovering information on specific aspects."

More Nmap pros

Cons

"The solution could use some additional components of the network culture, not only VMs. I'd like to see some additional security features because what they currently have concentrates only on the network."

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

"Sometimes, you encounter a VPN tunnel, network, or routing issue, but finding out more about the blockage is challenging."

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

"It's not the most friendly or straightforward to set up. I don't see the value versus the way you have to set it up at first."

More Azure Network Watcher cons

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

"The price is high and could be cheaper."

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

"I would like something more user-friendly to use and export data to various software."

"The price is high and could be cheaper."

"It takes a bit of time to get familiar with the solution and its options."

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

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

More Nmap cons

Pricing and Cost Advice

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

"The price of the solution is reasonable."

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

"Azure Network Watcher is a little bit expensive."

"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."

"I am using the free version of Nmap."

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).
