Senior System Administrator at Interactive Group
Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Assistant Vice President, Tech Solutions at LPL Financials
Has simplified remote software delivery and script management but needs improved reporting flexibility and better Mac support
NinjaOne's best features include ease of use regarding enablement and deployment, a broad selection and ability of software enablement, and API deliveries. Using CrowdStrike, we are able to tie in NinjaOne's API to have these automatically deliver to endpoints upon addition of those devices to a group with that policy deployed to it. NinjaOne has positively impacted our organization by making delivery easier for our end users and improving the ability to create scripts, manage scripts, and check status of devices and their compliance. This easier delivery with NinjaOne gives us oversight on devices without having to be on the call or remoted in directly to a device.
