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:

"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."

"Tanium has made the process of detecting threats more proactive with its detection. So, the process is easier and more efficient."
"Tanium is highly scalable."
"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 stable and it is also lightweight."
"The insights we gain from our endpoints and the management capabilities that Tanium provides have been a boon to our operations and security."
"For inventory purposes, it's from one of the best things on the scene, as you can get live inventory."
"It's definitely not complex, it is pretty user-friendly and it's a solid tool enterprise to use."
 

Cons

"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"The product does not have SAP monitoring."
"We're still experiencing stability issues with regards to collecting performance graphs."
"There's room for improvement in the visibility, and in the ability to extract information."
"The user interface needs improvement."
"Initially, we encountered problems during the setup as some errors were noted due to a few prerequisites not being fulfilled and having some configuration files to edit and plugins to add."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"Technical support is very good but is very expensive. It is becoming more and more expensive just like the upgrade."
"I would like to have more integrations and custom plugins to input."
"We set a policy to block USB access. The moment a device is being set up on the network, I apply the policy, but it does not come into effect immediately."
"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."
"Most of the time, agent-relative issues have to be more equipped with self-healing features."
"We had some issues with the solution's OS upgrade."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
