Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.

Stable product with an ability to build complex roles
We use Tanium as an EDR solution for managing end-user devices and servers The product is granular and can build complex roles compared to other EDR vendors. Tanium's dashboard UI could be similar to CrowdStrike. We have been using Tanium for two and a half years. The product is stable. I rate…

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 most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"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."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"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 allows us to configure any device so that we can send pager alerts when people don't have access to emails. It also allows us to schedule downtime and maintenance."
"I can monitor a software made in-house to software of bigger companies."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"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."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"I like the tool's incident response and security patching."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"The interrogation piece was the most valuable feature because it was very detailed."
"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."
"I find the inventory and compliance features of Tanium to be the most impressive."
 

Cons

"Nagios XI can improve its GUI for users with a new look."
"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."
"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."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"The installation and monitoring need improvement."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"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."
"Tanium’s scalability could be improved."
"The solution needs to improve the reporting and tracking capabilities."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
"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."
"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."
"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."
 

Pricing and Cost Advice

"Nagios XI is open source."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"The licensing fees for this solution are approximately $3,000 USD per year."
"As it is not an agentless tool, I think it is expensive."
"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 solution offers value for money."
"The solution is expensive but it's a good investment."
"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."
"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."
"There is an annual license required to use this solution."
