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

"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 Script Module in Nagios is really easy to use and is really cost efficient."
"Nagios XI helped me to draw the network and check for system failures."
"Overall, it's a powerful system."
"The overall performance of the product is superb."
"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."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails, and it also allows us to schedule downtime and maintenance."
"Nagios has good scalability."
"I would say Tanium is the best tool for vulnerability management."
"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."
"I like the tool's incident response and security patching."
"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."
"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 feature is its instant discovery aspect."
"The interrogation piece was the most valuable feature because it was very detailed."
"The product is granular and can build complex roles compared to other EDR vendors."
 

Cons

"Implementation on Windows was painful."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"There are stability issues if you have a large number of hosts and services."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough."
"While the UI is functional, I have always thought there was room for improvement here."
"The reporting structure could be more streamlined."
"I would like to see more customization in the network map because it is a bit tricky to use 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."
"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 can give a lot of false positives."
"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."
"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."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
"The most painful thing is the interface. It's a bit unclear sometimes."
"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

"Licensing costs are reasonable."
"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."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"Nagios XI is open source."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"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."
"There is an annual license required to use this solution."
"The solution is expensive but it's a good investment."
"It's an expensive solution. It would be nice if the cost were lower."
"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 product's pricing differs from region to region depending on negotiations and the number of endpoints."
"The solution offers value for money."
