Featured Reviews

Emanuel Kjellin - PeerSpot reviewer
An affordable solution to block and analyze the situation with VPN troubleshooting feature
If Azure Network Monitor is part of the solution, it's a comprehensive tool. For example, during cloud migration, the workload on the cloud can be significant. However, the Ethernet solution is low cost and provides a fast return on investment. In larger scenarios, such as a major deployment, the return on investment might take three months to a year. The solution involves managing workloads, machine storage, and network modes.

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

Pros

"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."
"I like the visibility."
"The solution is good for monitoring device behavior."
"The most valuable feature of Azure Network Watcher is the cloud-native application firewall. It is helpful for securing databases."
"The most valuable features I have found are typology, visualization, and capture."
"The solution is stable."
"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."
"From a functionality standpoint, it's robust and straightforward to comprehend."
"Nmap has a powerful command line tool and a set of diagnostic features."
"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."
"The initial setup was simple."
"The scanning procedure includes UDP ports which sets it apart from competitors."
"It is a very user-friendly product."
"The solution detects the operating systems, which makes testing the software much easier before making the payload."
"It helps us secure the network infrastructure."
 

Cons

"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."
"Azure is good, however, the Fortinet GUI is more intuitive and I like it more than anything else."
"Azure Network Watcher could improve by having other built-in applications. For example, an application to log activities for in and outbound traffic."
"The initial setup and initial learning curve could be improved to be easier."
"The solution could improve by limiting the need to clarify the logs. When the clarification is minimized, it is better for everyone involved."
"The initial setup and deployment could be improved to be simplified."
"User experience could be improved."
"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."
"They should deliver Playtech's username and password."
"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 solution should increase the number of features under a free license."
"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."
"There could be a specific option to check non-pingable endpoints for the product."
"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 are concerns with the stability of the product, making it an area where improvements are required."
 

Pricing and Cost Advice

"The price of the solution is reasonable."
"Azure Network Watcher is a little bit expensive."
"Price-wise, I have no information on how much Azure Network Watcher costs."
"The pricing is good. It's not too expensive."
"It's an open-source solution. Commerically, only the support service is available."
"The solution is open source so it is free."
"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."
"I am using the standard free version of Nmap."
"I am using the free version of Nmap."
"Nmap is an open-source product. You don't need a license to install it."
"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."
"Nmap is an open-source and free product."
