GreyNoise has recently released a new integration for Microsoft Sentinel, enhancing the capabilities of threat intelligence for business security. This integration provides security professionals with valuable insights into internet-wide scanning and reconnaissance activities. Tailored to offer a streamlined feed of threat indicators, it enables proactive threat identification and mitigation. Users can now leverage GreyNoise data within their threat-hunting queries and any analytics rules.

One of the most exciting aspects of our new integration is the seamless combination of GreyNoise’s data with Sentinel’s threat-hunting capabilities. Analysts now have a unique, robust ability to utilize GreyNoise data when investigating potential malicious patterns and anomalies within their network events. The integration also allows filtering out known opportunistic traffic during threat hunting to identify more targeted and malicious activity better.

To further enhance detection capabilities, the new content pack also introduces a set of analytics rules designed to identify and mitigate potential threats. By incorporating these indicators into analytics rules, security teams can take a more proactive approach to identifying known malicious behavior. By taking this approach, detections are elevated, and organizations can stay ahead of malicious actors that are commonly looking for exposed, vulnerable devices and misconfigured applications. 

In conclusion, integrating GreyNoise with Microsoft Sentinel offers a strategic advantage in navigating the cybersecurity landscape. By combining indicators from GreyNoise with analytics rules, hunting queries, and existing automation workflows, analysts now wield an indispensable toolkit to combat evolving threats proactively.

Explore the latest content pack available on the Azure marketplace to start ingesting GreyNoise indicators into Microsoft’s Sentinel’s threat intelligence platform. You' will need a current GreyNoise trial or Enterprise license to access the GNQL API endpoint for data ingestion.  If you do not have access to either, contact us for more information and to get started.
