Announcing Lumen Defender℠ AMDR with Microsoft Sentinel: advanced managed detection & response powered by Black Lotus Labs®

A new era for Lumen and Microsoft customers is here: Lumen Defender^℠ Advanced Managed Detection & Response (AMDR) with Microsoft Sentinel delivers real-time, network-driven threat intelligence and 24/7 security operations, empowering organizations to detect, respond to and mitigate advanced cyber threats. In today’s rapidly evolving threat landscape, customers need a managed detection and response solution that goes beyond endpoint visibility—enabling them to proactively defend against sophisticated adversaries with greater speed, confidence and context.

This collaboration between Lumen and Microsoft brings together two industry leaders to deliver real-time, curated threat intelligence—empowering security teams to stay ahead of threats and strengthen their security posture. The Lumen Defender AMDR solution provides continuous, expert monitoring and rapid response, giving customers peace of mind in the face of evolving cyber threats.

Bringing network-driven threat intelligence to Microsoft Sentinel

As cyber threats grow in complexity and scale, security teams need more than just endpoint visibility—they need insight into the global infrastructure attackers use. Lumen leverages the unparalleled reach and operational strength of our global internet backbone, powered by the threat research expertise of Black Lotus Labs^®. With Lumen Defender AMDR, organizations can now access high-fidelity, network-based threat intelligence directly within Microsoft Sentinel, Microsoft’s cloud-native Security Information and Event Management (SIEM) and AI-first security platform.

This integration empowers Security Operations Center (SOC) analysts and security teams to enrich alerts, pinpoint critical threats and accelerate incident response by connecting internal signals to external adversary infrastructure. The result is fast, informed decision-making and enhanced security posture.

“Keeping customers safe from evolving cyber threats often requires expert help. We are delighted that Lumen, with its Advanced Managed Detection and Response and Black Lotus Labs Threat Intelligence and services expertise, combined with Microsoft Sentinel, is here to help customers strengthen their security,” said Vasu Jakkal, CVP Microsoft Security. “This collaboration delivers network-driven threat visibility and 24/7 managed security operations—empowering organizations to detect, respond to, and mitigate advanced cyber threats with speed and confidence. By combining Lumen’s global backbone intelligence with Microsoft Sentinel, we’re helping our mutual customers strengthen their security posture and stay ahead of evolving threats.”

How Lumen Defender AMDR with Microsoft Sentinel works

Lumen Defender AMDR delivers continuous, 24/7 monitoring, detection and response through a cloud-based managed SOC. The service is designed to protect enterprises offering:

• Real-time threat visibility: Harnessing the Lumen global internet backbone—the #1 peered network^¹—and direct observation of global network activity.
• Curated, actionable intelligence: Delivering validated Indicators of Compromise (IOCs) with enriched context, including threat category, risk, and campaign mapping.
• Seamless operationalization: Rapid deployment in Microsoft Sentinel, with pre-built analytics rules and dashboards to make threat intelligence impactful and integrating Lumen Defender AMDR with Microsoft Sentinel, security teams can correlate internal enterprise alerts with external adversary infrastructure, prioritize high-fidelity threats and respond faster with enriched context.

The power of collaboration: Lumen and Microsoft

Security teams today face an overwhelming volume of alerts—many of which lack actionable context or connection to broader threat campaigns. Analysts often spend hours chasing signals from endpoints, firewalls and cloud workloads, only to be left with fragments that don’t tell the full story.

Lumen network-derived intelligence, powered by Black Lotus Labs^®, changes the game. Think of endpoint intelligence as monitoring your house from the inside—you’ll know when someone tampers with a lock. Lumen network intelligence is like having an aerial view of the entire neighborhood, spotting suspicious vehicles and coordinated movements before they reach your door.

In addition to delivering network-driven threat intelligence, Lumen infrastructure is uniquely positioned to support Microsoft’s next generation of AI-powered cloud services. As AI workloads demand unprecedented scale, speed and reliability, the Lumen global backbone combined with metro edge compute capabilities provides the high-performance connectivity required for mission-critical applications. This AI-ready network fabric enables Microsoft to accelerate innovation, helping to ensure solutions like Microsoft Azure, Microsoft 365 Copilot and Microsoft Foundry, including Azure OpenAI remain performant and secure—even as the complexity of cyber threats and data volumes continue to grow.

This outside-in visibility allows Black Lotus Labs^® to trace malicious IPs to broader infrastructure, uncover related domains, identify other victims and attribute activity to known threat groups. By connecting internal alerts to external adversary operations, Lumen and Microsoft enable security teams to enrich detection, reduce false positives and accelerate response.
