Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Immediate results in patching promptly address vulnerabilities
When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium. I have to search outside to download patches, create bundles, and then perform the task. It would be easier if Tanium provided the patches directly. Some other brands provide the patch with a direct download link, which facilitates the process. Also, I feel that if there were more detailed documents and remediations readily available online for troubleshooting, especially more up-to-date information, it would be beneficial. Currently, some resources online are very out-of-date.

Quotes from Members

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

Pros

"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"The solution is pretty stable."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"The installation is no problem. I've installed Nagios several times."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"We love Nagios XI due to the fact that JPS Web is very useful."
"This is a very good solution and it is simple to use, for any company."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"Tanium's most valuable feature is its instant discovery aspect."
"For incident response tasks, all these tasks can get done in minutes with minimal disruption to the end-user."
"The product is granular and can build complex roles compared to other EDR vendors."
"I'm not so familiar with the tool but I like the interaction of the console to the picture. Patching is the primary model I have been focusing on for the last couple of weeks. So I have created a proof of concept environment and have been checking the available features."
"Tanium is a very good product and I would rate it eight or nine out of ten."
"The interrogation piece was the most valuable feature because it was very detailed."
"I find the inventory and compliance features of Tanium to be the most impressive."
"I like the tool's incident response and security patching."
 

Cons

"The Configuration Wizard needs improvement, because not all vendors are present."
"We'd like to see more integration capabilities."
"The product's stability could be even better."
"I would like to see support for notification via SMS."
"The user interface needs improvement."
"The product does not have SAP monitoring."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"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."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
"When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium."
"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."
"The main issues are the network connection because different customers have issues with their networks. It's difficult implementing this type of solution because the network is the main feature in the architecture for these types of solutions. Tanium could improve by creating some network optimization."
"Most of the time, agent-relative issues have to be more equipped with self-healing features. At times, the agent is there, but for some reason, it doesn't report a status. It gives certain problems that are obviously agent-based."
"It is not really additional functions, or the features that are needed, rather the complexity would be reduced based on the number of modules required to put together a comprehensive operational security and risk compliance model."
"The solution needs to improve the reporting and tracking capabilities."
"When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium. I have to search outside to download patches, create bundles, and then perform the task."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
