On January 14, 2025, Corelight, a leading provider of network detection and response (NDR) solutions, announced a transformative integration with Microsoft Defender for Endpoint and Microsoft Defender Vulnerability Management. This development aims to enhance network visibility and improve incident response capabilities for organizations navigating the increasingly complex cybersecurity landscape.

Enhancements in Detection and Response

The integration allows Corelight’s sensors to directly receive data from Microsoft Defender, significantly improving the mean time to detection (MTTD) and increasing the efficiency of Security Operations Centers (SOCs). By utilizing powerful risk-based alert prioritization, organizations can streamline their incident response processes across both on-premises and multi-cloud environments. This is especially critical as security teams often struggle to manage the overwhelming volume of alerts generated by various security tools.

According to research from the SANS Institute, most SOC teams rely heavily on alerts from endpoint security solutions to trigger incident responses. The new integration enriches Corelight logs with real-time data from Microsoft Defender, enabling SOC teams to focus on their most critical vulnerabilities and risks. This strategic enhancement not only aids in quicker investigations, but also helps mitigate analyst fatigue caused by alert overload.

Unified Data View for Enhanced Investigations

The integration provides a unified view of network telemetry combined with endpoint and vulnerability data.

This allows SOC teams to conduct:

  • Enhanced Detection: Corelight’s network telemetry now includes prioritized alerts based on environmental risks observed on the network.
  • Streamlined Response and Asset Inventory: By incorporating unique device IDs from Microsoft Defender, SOC teams can seamlessly transition between NDR and endpoint detection and response (EDR) telemetry, accelerating investigations.
  • Expanded Visibility: Users gain improved visibility into all devices on the network, including unmanaged and unknown endpoints.

Addressing Security Challenges

As cyber threats continue to evolve, organizations face mounting pressure to maintain a strong security posture. The integration of Microsoft Defender data into Corelight’s platform addresses this challenge by providing security teams with enriched insights that facilitate faster and more accurate investigations. By focusing on real-time data, organizations can respond proactively to emerging threats rather than reacting after incidents occur.
