Back in 2018, Palo Alto Networks CTO and co-founder Nir Zuk coined a new term to describe the way that businesses needed to approach cybersecurity in the years to come. That term, of course, was extended detection and response (XDR). It described a unified cybersecurity infrastructure that brought endpoint threat detection, network analysis and visibility (NAV), access management, and more under a single roof to find and neutralize digital threats in real-time.

And Zuk’s vision of XDR proved prophetic. In the years since he coined the phrase, platforms leveraging the XDR model have emerged as the de-facto leaders of the business cybersecurity industry. But their scale and complexity put them in a product class that’s just out of reach for some enterprises.

Fortunately, the open-source community — as it often does — has filled the XDR void with an affordable product — because it’s totally free. It’s called Wazuh, and it provides enterprises the tools they need to build a customized XDR solution that meets their cybersecurity and budgetary needs at the same time. Here’s how.

The Key Features of an XDR Platform

Although the varied implementations of XDR solutions come with varying feature sets, most XDR platforms have a few major features in common. They include:
