Security operations centers (SOCs) are facing a growing paradox: They have more data and tools than ever, yet detecting and responding to threats remains painfully slow.

According to Palo Alto Networks, the problem isn’t a lack of visibility — it’s the inability to act on it quickly enough.

“The evidence is always there,” says Senior Partner Architect Bob Vish. The problem “is how quickly we can see it, how close we can get to real time and how well we can avoid what I call a failure of imagination.”

That challenge is driving increased interest in extended detection and response (XDR) platforms, such as Cortex XDR, which aim to unify data sources, reduce alert noise and automate response.

From Tool Sprawl to Unified Detection

Traditional SOCs rely on a patchwork of tools — endpoint detection and response (EDR), security information and event management (SIEM) systems, network monitoring and more. While each plays a role, stitching them together often creates operational friction. “Most SIEMs are like Lego building blocks,” Vish says. “They require a great deal of expertise to build and maintain, and they can become expensive, especially when you’re ingesting large amounts of data.”

XDR platforms take a different approach. Rather than treating alerts as isolated events, they ingest telemetry from endpoints, networks and other sources to build a real-time picture of attacker behavior.
