Featured Reviews

Emmanuel Appiah Boateng - PeerSpot reviewer
Network and Security Engineer at a educational organization with 1,001-5,000 employees
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.
Not Joseph Pearson - PeerSpot reviewer
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.
