Whisper

The **Whisper Security** solution for Microsoft Sentinel brings the Whisper internet-scale infrastructure knowledge graph (7+ billion nodes, 39+ billion edges, 40+ threat feeds) into Microsoft Sentinel's detection and response workflows. It provides real-time threat intelligence enrichment, infrastructure context, WHOIS/BGP history, and ASN reputation polling. **Underlying Microsoft technologies used:** - [Azure Logic Apps](https://azure.microsoft.com/services/logic-apps/) for enrichment playbooks - [Microsoft Sentinel custom tables](https://learn.microsoft.com/azure/azure-monitor/logs/create-custom-table) for storing enriched threat/infrastructure data - [Azure Key Vault](https://azure.microsoft.com/services/key-vault/) for Whisper API key storage
