"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."
"Nagios was easy to implement and the support staff has been great for any minor issues we encountered. Nagios was easy to deploy and very affordable where many other tools were way too complicated and expensive. We are so happy with Nagios, and it has freed us up to focus on other initiatives."
"I deployed Nagios XI and NNA as a pilot. Management was thrilled and issues/outages were cut drastically. I have been using Nagios since the days of Net Saint. There are no other options as far as I am concerned."
