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.

Pros

"The dashboard allows you to see what's going on in the overall system."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"We love Nagios XI due to the fact that JPS Web is very useful."
"It's great for monitoring IT services infrastructure."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"I can monitor a phone on a desk to very big servers of any company."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"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 initial setup was simple."
"Nmap is easy to use. It's a command-line interface, and the output is quite good."
"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 scanning procedure includes UDP ports which sets it apart from competitors."
"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."
"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 has a powerful command line tool and a set of diagnostic features."
 

Cons

"The Configuration Wizard needs improvement, because not all vendors are present."
"The GUI could be improved."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"Nagios XI can improve its GUI for users with a new look."
"The product's stability could be even better."
"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"I would like to see support for notification via SMS."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"The solution is not that easy for a beginner to learn."
"There are concerns with the stability of the product, making it an area where improvements are required."
"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 solution should increase the number of features under a free license."
"Nmap needs to improve its scanning speed."
"The solution's initial setup could be better."
"There could be a specific option to check non-pingable endpoints for the product."
"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."
 

Pricing and Cost Advice

"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"As it is not an agentless tool, I think it is expensive."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"Licensing costs are reasonable."
"Nagios XI is open source."
"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 free of cost, but there are specific services that we have to buy."
"I am using the standard free version of Nmap."
"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."
"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."
"Nmap is an open-source product. You don't need a license to install it."
