Valuable reporting and alert system with room for PDF export improvements

The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Offers easy-to-use features and helps scan ports

The product's port scan capabilities have positively impacted my company's network management tasks. The OS detection feature has benefited our company's network analysis since it shows me the open ports that are vulnerable. The product helps me get details about the vulnerability in open ports. I have not integrated the product with other tools except for the fact that I have used Nmap in Metasploit. I recommend the product to those who plan to use it for network security and management. The tool provides full scanning of ports. Though there are other products in the market, many of the solutions are not as good as Nmap, which offers a lot of features that are easy to use. I rate the solution a nine out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Nagios Core is very configurable. Whatever you want, you can do it."

"Nagios Core is stable."

"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."

"Dashboard provides monitor of total assets."

"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."

"The reporting structure and the feature set are valuable to me."

"We mostly use Nagios Core to integrate with Python and Bash Script."

"We use the product to monitor server applications."

More Nagios Core pros

"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 most valuable feature of the solution for security audits stems from the fact that it serves as a powerful tool with the ability to scan a large number of ports."

"It helps us secure the network infrastructure."

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

"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."

"The scanning procedure includes UDP ports which sets it apart from competitors."

"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."

"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."

Cons

"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."

"t was a little hard to get our setup represented in the configuration."

"The mapping is a little hard."

"The scalability needs improvement, it's not scalable at this time."

"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."

"The user interface could be more interactive because it is pretty basic."

"The dashboard and monitoring features could be improved."

"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."

More Nagios Core cons

"The solution's initial setup could be better."

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

"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."

"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 is not that easy for a beginner to learn."

"Customization is not very user-friendly in Nmap."

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

More Nmap cons

Pricing and Cost Advice

"The enterprise version has technical support. The version we are using is free."

"Most the plugin features are free."

"Nagios Core is a cheap solution."

"It's free."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"The product is cheaply priced."

"It's free."

"We are using the open-source, unpaid version."

More Nagios Core pricing and cost advice

"I am using the free version of Nmap."

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

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

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

"The solution is free of cost."

"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 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."

Overview

This is IT infrastructure monitoring's industry-standard, open-source core. Free without professional support services.

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).
