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.

Centralized policies have improved remote endpoint control and have simplified data visibility
The integration is not simple and easy. It requires experienced users or people who have done the implementation. When certain policies are applied, they do not immediately push the policies. For example, we manage endpoint device USB access. We set a policy to block it, but it does not come into effect immediately. Sometimes it takes three or four days for it to reflect. That is a pain point. I have raised this issue with support as well, but they said that I need to limit the number of devices in the policy. In terms of application deployment, for us, it was seamless.

Quotes from Members

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

Pros

"It provides an easy and powerful solution to network monitoring so I can pay attention to other concerns."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"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."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"Nagios is an open source monitoring tool for monitoring network services, with easy installation, a user-friendly and configurable interface, and the ability to monitor disk space, CPU utilization, memory usage, host availability, NFS availability and many other things, making it widely used in IT markets."
"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"In my view this product is very good value for money when compared with other commercially provided monitoring solutions."

"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."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"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."
"I find the inventory and compliance features of Tanium to be the most impressive."
"Tanium has made the process of detecting threats more proactive with its detection. So, the process is easier and more efficient."
"Threat hunting is a very good feature on Tanium. We have just started using it and have not used it extensively."
"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."
 

Cons

"Technical support is an area that needs improvement. It is not available 24/7."
"Nagios XI isn't really good for scaling, in my experience."
"The reporting structure could be more streamlined."
"We'd like to see more integration capabilities."
"I feel that the maturity and user interface needs to be improved."
"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."

"There are some bugs in the product. The tool needs to improve in the area of reporting."
"Tanium’s scalability could be improved."
"Tanium required local admin or root rights on Mac devices, which did not comply with our security policies. This made the solution less suitable for our restrictive environment."
"We had some issues with the solution's OS upgrade."
"There are downsides and drawbacks in Tanium, and there is room for improvement from my perspective."
"The most painful thing is the interface. It's a bit unclear sometimes."
"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."
"The solution needs to improve the reporting and tracking capabilities."
