Over ten months, Ryan Greatlove engineered security automation and data integration features for the Azure/Azure-Sentinel repository, focusing on cloud security and incident response. He developed and refined AWS Security Hub connectors, analytic rules, and playbooks, enabling seamless ingestion and mapping of threat intelligence into Microsoft Sentinel. Leveraging C#, Python, and ARM templates, Ryan implemented CI/CD pipelines, schema validations, and managed identity authentication to ensure reliable deployments and robust security posture. His work included technical documentation, deployment template hardening, and MITRE ATT&CK mapping, resulting in improved detection coverage, maintainability, and operational efficiency for cross-cloud security monitoring and automated incident triage.

September 2025 monthly summary for Azure/Azure-Sentinel. Key deliverables included MDTI Automated-Triage Playbook enabling reputation-based enrichment, automatic tagging of suspicious/malicious events, and dynamic severity adjustments for Microsoft Sentinel incidents; across MDTI playbooks, Managed Identity authentication was implemented with ARM template refactors and updated prerequisites/docs. These changes streamline incident triage, strengthen security posture through identity-based deployment, and simplify future deployments. No major bugs reported this month; minor identity-related adjustments were completed. Changes validated in CI/CD and documented for ongoing maintenance.
