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 Currently, some resources online are very out-of-date.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

"It's great for monitoring IT services infrastructure."
"It is an open-source platform with valuable features for performance and stability."
"The most valuable feature is the monitoring of processes."
"I can monitor a phone on a desk to very big servers of any company."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"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."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails. It also allows us to schedule downtime and maintenance."
"I like the fact that you can create patching campaigns depending on the area of your network that you want to address first. I like the ability it has to make several campaigns that work in parallel."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"The solution is scalable and helps to understand how infrastructure works. It helps to improve the health of the organization."
"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."
"I like the tool's incident response and security patching."
"The most valuable features of this solution are the consolidation of all historical data on device endpoints, security drivers, firmware, and Software version gaps."
"Tanium’s best features include support for any Windows, Linux, or Mac endpoint, regardless of where it is, and the ability to do IT operations and security operations."
"The security features are very valuable."
 

Cons

"The installation and monitoring need improvement."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"Open-source software is usually not user-friendly."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"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."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"The solution needs to improve the reporting and tracking capabilities."
"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
"The solution can give a lot of false positives."
"The performance could improve in future releases. We have had performance issues in specialized web environments, but overall I think the problems are less than 2% of the computer systems being used."
"Any movement into a SaaS solution has challenges since the processes and data flows are not well defined. Hence, you need to build it at the same time."
"They could improve the UI."
"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."
 

Pricing and Cost Advice

"Nagios XI is an expensive solution."
"The pricing is high with separate licensing for the product and support."

"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"We are using the free version of this solution."
"Licensing costs are reasonable."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"There is an annual license required to use this solution."
"The product's pricing differs from region to region depending on negotiations and the number of endpoints."
"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."
