“If we can monitor it, we can control it. We are alerted to things we can fix before they become big problems.”
– Fadi Sodah, Director of ICT
We’ve worked with thousands of businesses of all sizes across the globe. Read what they have to say about our solutions.
“The biggest advantage of Nagios for us is its customizations. Nagios has simplified a very large job, allowed us to make the necessary customizations needed and provided us with a community that is a valuable resource when a new requirement comes up.”
“With Nagios, we are better prepared to provide statistics and trending, which gives us a base for data-driven decision-making. This data has impacted the way we buy servers, provision and restrict bandwidth, and react to anomalies, events, and problems.”
“Before monitoring, we couldn’t even spend the bulk of our time fighting fires; we were spending time finding them. Now, our system is nearly self-healing. Nagios is super easy to install and configure, runs on standard bash scripts, and allows us to automate anything.”
“We are a telecommunications company and the leader in our region. Our monitoring goals were fulfilled with Nagios. We had all of our devices monitored 24/7 and were able to take advantage of all the reports and tools that Nagios has to offer.”
“We specialize in network access control, and we needed a system that was able to monitor our mission-critical servers and routers as there was nothing in place prior. Nagios has been great for us. I’m able to take care of issues before they become fires or jump on them when they happen, at the very least.”
“With Nagios, we were able to consolidate multiple commercial monitoring solutions into one and, at the same time, reduce our maintenance costs.”
“We have been able to work with Nagios to determine our best possible interfaces and workflows to make our monitoring system work with us instead of against us. The flexibility and expandability of Nagios are second to none.”
“The efficiency and proactivity levels of our resources were raised. Nagios’ centralized monitoring provided an excellent panoramic view, and our troubleshooting time decreased. The valuable and precise information was presented in well-organized reports.”
“As a consultancy and service provider, it’s up to us to imagine what our customers can monitor. Nagios XI gives us inspiration for what’s possible. We really appreciate the graphs, pre-sets, and configuration inserts. Our customers love the reporting because we can customize the reports for what they need.
“By moving to Nagios XI, we got everything we wanted on a graphic interface. We don’t have to edit or change anything in the command lines. We don’t have to define groups manually. We don’t have to customize the plugins manually. We can perform insightful dashboarding and alerting. It’s much, much better.”

*Nagios XI's plans are primarily based on the Node-count of the license. A Node is anything with an IP address or Fully Qualified Domain Name (FQDN) that you would like to monitor (switches, routers, firewalls, workstations, and other network devices). There are no restrictions on the number of Services you can monitor. While paid licenses of Nagios XI do not contain any software-imposed limitations, we have found that systems performing more than 15,000-20,000 checks in a 5-minute interval should consider following our Server Considerations Guide to ensure the best performance on your installation.
Nagios XI also offers an Enterprise add-on which enhances the software's capabilities. This addition allows users to schedule reports, project future values with capacity planning, and much more. Refer to our Enterprise documentation or contact a Nagios sales representative to learn more about the capabilities of the Enterprise-level license.
With the purchase of a Nagios XI license, you receive access to Premium Features as part of your Maintenance & Support benefits for the first year. After the first year, renewal of your Maintenance & Support plan is required to maintain this feature set. This includes features such as Single-Sign On (SSO) via MS Azure AD, the Nagios Mod-Gearman user interface, and a collection of premium Wizards!
To learn more and see the full list of features, you can visit our article on Premium Features or email [email protected].
