Microsoft Sentinel is a cloud native SIEM that offers various options to import threat intelligence data and use them for hunting, investigation, analytics etc. Some of the ways to import rich threat intelligence data into Microsoft Sentinel include the Threat Intelligence - TAXII data connector, Threat Intelligence Platforms (TIP) connector and import of indicators through a flat file.
Microsoft Sentinel was one of the early adopters of STIX/TAXII as the preferred way to import threat intelligence data. Microsoft Sentinel “Threat Intelligence -TAXII” connector uses the TAXII protocol for sharing data in STIX format. This data connector supports pulling data from TAXII 2.0 and 2.1 servers. The Threat Intelligence – TAXII data connector is essentially a built-in TAXII client in Microsoft Sentinel to import threat intelligence from TAXII 2.x servers.
Today we are announcing our integration with Pulsedive, which allows you to get threat intelligence data from Pulsedive into Microsoft Sentinel using the Threat Intelligence – TAXII Data Connector.
Pulsedive + Microsoft Sentinel Solution
The Pulsedive + Microsoft Sentinel integration offers automated, bulk enrichment and more meaningful alerting on indicators of compromise (IOCs). The integration streamlines your CTI ingestion and uses Pulsedive's risk scoring to reduce noise. This integration has made getting TI from Pulsedive into Microsoft Sentinel extremely quick and easy without the need to contact the Pulsedive sales to get access to the TI feed.
Pulsedive’s threat intelligence database includes ingestion and vetting of dozens of reputable open-source feeds, as well as unique, real-time community contributions. Combined with Sentinel’s security analytics capabilities, this integration helps users gain key visibility and context into IOCs associated with malware, phishing, scams, ransomware, threat groups, and more - to help teams reduce time chasing down key data and shift focus to meaningful, challenging work.

Put Pulsedive threat intelligence to use in Microsoft Sentinel
Once the threat intelligence from Pulsedive is imported into Microsoft Sentinel, you can use it for matching against log sources. This can be done using the out-of-the-box analytic rules in Microsoft Sentinel. These completely customizable analytics rules used to match threat indicators with your event data all have names beginning with, ‘TI map’.
To learn how to enable and create analytic rules, follow the steps mentioned in this documentation.
You can also create customized dashboards using Workbooks in Sentinel to get a deeper understanding of the threat landscape covered by the Pulsedive feed.
Hope this article has helped you understand the advantages of importing the Pulsedive feed into Microsoft Sentinel and use it to protect your organization.
