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.

Immediate results in patching promptly address vulnerabilities
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. It would be easier if Tanium provided the patches directly. Some other brands provide the patch with a direct download link, which facilitates the process. Also, I feel that if there were more detailed documents and remediations readily available online for troubleshooting, especially more up-to-date information, it would be beneficial. Currently, some resources online are very out-of-date.
