Lumen expands managed detection and response service for Palo Alto Networks' Cortex XSIAM

Lumen Technologies has launched Lumen Defender Advanced Managed Detection and Response (AMDR) for Palo Alto Networks Cortex XSIAM, expanding its managed security services to address rising alert volumes and faster-moving cyber threats.

The service combines Lumen's managed detection and response capabilities with its Black Lotus Labs threat intelligence feed and Palo Alto Networks' Cortex XSIAM AI-driven SOC platform. Lumen said it is designed to help enterprises modernise security operations, cut alert fatigue, and accelerate detection and response.

A key element of the offering is the Black Lotus Labs threat feed, which Lumen said draws on activity observed across its own network rather than relying solely on endpoint or log telemetry. The company said that approach provides earlier visibility into attacker infrastructure - including reconnaissance and staging activity - before attacks reach customer environments.

Lumen Defender AMDR for Cortex XSIAM supports both co-managed and fully managed SOC models, allowing organisations to add capability without replacing existing security teams. The service is built around a single unified platform, aiming to reduce tool sprawl and console-switching, and automate incident investigation and response.

"Cyber defence is a speed game, and the network is where threats often show up first," said Jim Fowler, chief technology and product officer at Lumen Technologies.

"With Palo Alto Networks, we're again raising the bar for security by expanding access to our high-value network threat intelligence and putting it to work through modern, automated operations."

"Securing the modern enterprise means eliminating complexity and accelerating time-to-resolution," said Simone Gammeri, chief partnership officer at Palo Alto Networks.

"Combining Lumen's network-level threat intelligence with Cortex XSIAM empowers organisations to proactively defend against sophisticated threats at machine-speed."
