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 most valuable feature is the monitoring of processes."
"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."
"The installation is no problem. I've installed Nagios several times."
"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."
"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."
"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"Our infrastructure is now under monitoring proactively and we don't have to wait for complaints from the customers or internal operation team to inform regarding any issue with the service."
"Nagios has good scalability."
"Tanium is used for endpoint management, specifically patching and configuration management."
"I like the tool's incident response and security patching."
"Tanium is stable and it is also lightweight."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"The security features are very valuable."
"Threat hunting is a very good feature on Tanium. We have just started using it and have not used it extensively."
"Tanium is highly scalable."
"The solution is scalable and helps to understand how infrastructure works. It helps to improve the health of the organization."
 

Cons

"For some, it may be difficult to deploy."
"There's room for improvement in the visibility, and in the ability to extract information."
"The reporting structure could be more streamlined."
"This solution would be improved with the inclusion of additional services. Monitoring streaming services is an example of something that is not currently supported, so in order to handle this, I would have to write a script."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"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."
"However, it is a bit complex and difficult for a first-time user."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"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."
"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."
"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."
"We had some issues with the solution's OS upgrade."
"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."
"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 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."
 

Pricing and Cost Advice

"As it is not an agentless tool, I think it is expensive."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios XI is an expensive solution."
"The pricing is high with separate licensing for the product and support."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"We are using the free version of this solution."
"The product's pricing differs from region to region depending on negotiations and the number of endpoints."
"It is higher than some competitors in the market."
"There is an annual license required to use this solution."
"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."
"The solution is expensive but it's a good investment."
"The solution offers value for money."
"It's an expensive solution. It would be nice if the cost were lower."
