Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.

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.

"I can monitor a phone on a desk to very big servers of any company."
"It enables us to delve deeper and identify the services and open ports on the system and visualize this information on a dashboard automatically."
"Nmap is easy to use. It's a command-line interface, and the output is quite good."
"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."
"The solution detects the operating systems, which makes testing the software much easier before making the payload."
"It helps us secure the network infrastructure."
"Nmap has a powerful command line tool and a set of diagnostic features."
"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."
"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."
 

Cons

"The product's stability could be even better."
"Nagios XI can improve its GUI for users with a new look."
"The user interface needs improvement."
"I would like to see support for notification via SMS."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"It can be quite difficult to know which drivers and agents to use when setting up."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"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 should increase the number of features under a free license."
"Nmap major operates through the CLI; there's no GUI component, and that's where the challenge is."
"The solution is not that easy for a beginner to learn."
"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."
"The price is high and could be cheaper."
"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 solution's initial setup could be better."
 

Pricing and Cost Advice

"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"We are using the free version of this solution."
"As it is not an agentless tool, I think it is expensive."
"Licensing costs are reasonable."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios XI is open source."
"Nagios XI is an expensive solution."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"I am using the free version of Nmap."
"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."
"The solution is open source so it is free."
"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."
"It's an open-source solution. Commerically, only the support service is available."
"The solution is free of cost."
"Nmap is an open-source and free product."
