Microsoft Sentinel Repositories

Project overview

Microsoft Sentinel Repositories gives security teams a content-as-code workflow for deploying and managing custom Sentinel content from GitHub or Azure DevOps. Repository connections synchronize version-controlled content into Sentinel workspaces through automated deployment pipelines.

My contribution

At Microsoft, I contributed across the Repositories experience, including service reliability, customer issue investigation, frontend maintenance, accessibility, and release readiness. I developed the initial Bicep support as a hackathon project, helped move it through preview, and later led frontend work supporting the broader Repositories release.

I also proposed adding metadata to content deployed by the service and implemented the change across supported resource types. This gave the team its first reliable way to measure adoption, including how many customers were using Repositories and how many resources it deployed.

Public release

Microsoft’s public documentation describes Repositories as the source of truth for custom Sentinel content, with support for both Bicep and Azure Resource Manager templates. An announcement by Ofer Shezaf details the addition of Bicep support.
