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

"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements, it is flexible and easy to integrate with our systems, and you can customize the solution by adding additional features using code."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"Nagios is my favourite open source monitoring system."
"This solution has improved our ability to determine the source of a connection failure in our network, and now we are able to monitor the service provider's router and make that determination."
"The technical support is good."
"We love Nagios XI due to the fact that JPS Web is very useful."
"I like the tool's incident response and security patching."
"It's definitely not complex, it is pretty user-friendly and it's a solid tool enterprise to use."
"The security features are very valuable."
"Tanium is used for endpoint management, specifically patching and configuration management."
"The solution's technical support is very responsive."
"Tanium has made the process of detecting threats more proactive with its detection. So, the process is easier and more efficient."
"Tanium's most valuable feature is its instant discovery aspect."
"The product is granular and can build complex roles compared to other EDR vendors."
 

Cons

"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"The tool's AI model needs to be fixed."
"Technical support is very good but is very expensive. It is becoming more and more expensive just like the upgrade."
"I would like to see support for notification via SMS."
"We'd like to see more integration capabilities."
"The Configuration Wizard needs improvement, because not all vendors are present."
"The user interface needs improvement."
"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."
"The solution lacks mobility."
"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."
"We had some issues with the solution's OS upgrade."
"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."
"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 most painful thing is the interface. It's a bit unclear sometimes."
