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.
