Breaking Down the Real Meaning of an XDR Solution

In a crowded market where every security vendor claims to offer Extended Detection and Response (XDR), it’s easy to get lost in the hype. Many so-called XDR solutions simply bolt together a couple of capabilities—usually EDR and some SIEM integration—and call it a day. But real XDR is more than a buzzword. It’s a cohesive, unified platform that provides deep visibility and response capabilities across all critical attack surfaces.

At Fidelis Security, we break down what a true XDR solution should look like—one that combines Endpoint Security, Network Detection and Response, Deception Technology, and Active Directory Protection into a single, integrated platform. No patchwork. No silos. Just full-spectrum defense designed to detect, hunt, and respond to threats in real time.

This whitepaper explores the pitfalls of fragmented XDR solutions and highlights the core capabilities that define an authentic, effective approach to XDR. Because when it comes to securing your enterprise, “good enough” just isn’t enough.
