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

"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"This is a very good solution and it is simple to use, for any company."
"Overall, it's a powerful system."
"It's very easy to install it and manage it with Nagios XI's interface."
"It has a wide variety of plugins in existence, but when there's no plugin available it is quite simple to integrate one's own programs and scripts."
"Nagios XI is an outstanding network Monitoring tool, which can be tweaked to suit any environment and it is a good solution for business looking for remarkable features at zero cost."
"We love Nagios XI due to the fact that JPS Web is very useful."
"The solution's most valuable feature is its simplicity."
"The product is granular and can build complex roles compared to other EDR vendors."
"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."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"I would say Tanium is the best tool for vulnerability management."
"The interrogation piece was the most valuable feature because it was very detailed."
"Tanium is a very good product and I would rate it eight or nine out of ten."
"Tanium has made the process of detecting threats more proactive with its detection. So, the process is easier and more efficient."
 

Cons

"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"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."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"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."
"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 installation and monitoring need improvement."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"Open-source software is usually not user-friendly."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
"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."
"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."
"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."
"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."
"The solution lacks mobility."
"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."
 

Pricing and Cost Advice

"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is high with separate licensing for the product and support."
"We are using the free version of this solution."
"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."
"Licensing costs are reasonable."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."
"It is higher than some competitors in the market."
"The solution is expensive but it's a good investment."
"The solution offers value for money."
"There is an annual license required to use this solution."
"It's an expensive solution. It would be nice if the cost were lower."
"The product's pricing differs from region to region depending on negotiations and the number of endpoints."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
