The Best Endpoint Security Monitoring and Management Tools to Consider in 2021

Thousands of endpoint devices and hundreds of servers. That’s what some of us are trying to manage within our IT department. But even if your organization only has a few hundred or dozens of devices, it’s still a lot of work trying to find out which software products were downloaded to which device, which endpoint doesn’t have the latest antivirus patch, and whether there’s any malware in your network.

Endpoint security software exists to make our lives easier. It enables companies to meet both internal and external compliance requirements and helps IT and security team members gain actionable insights.

To help you choose, here are some of the best endpoint security monitoring tools available in the market today. We chose the most efficient tools, then let them pretty much tell their own story (today’s guide is based on official company information across websites and LinkedIn profiles).
