title Platform Comparison: GitHub vs Azure DevOps
description Feature-by-feature comparison of GitHub and Azure DevOps for the Agentic Accelerator Framework, covering security scanning, SARIF integration, custom agents, dashboards, and governance capabilities.

Overview

GitHub is the preferred platform for the Agentic Accelerator Framework. Azure DevOps (ADO) is a first-class citizen. Many organizations operate in a hybrid GitHub and ADO environment, and this framework supports both platforms with equivalent security, accessibility, code quality, and FinOps controls.

Feature Comparison

Framework Feature GitHub Azure DevOps Notes
Secret Scanning GitHub Secret Protection GHAzDO Secret Protection Push protection on both
Dependency Scanning (SCA) Dependabot + Dependency Review GHAzDO Dependency Scanning ADO uses pipeline task
Code Scanning (SAST) CodeQL + Copilot Autofix GHAzDO CodeQL Same CodeQL engine on both
SARIF Upload (custom tools) upload-sarif action AdvancedSecurity-Publish@1 Accessibility scanner works on both
IaC Scanning MSDO GitHub Action MSDO ADO Task Same MSDO tool on both
DAST ZAP GitHub Action ZAP ADO Task Same ZAP tool on both
Security Overview Org-wide dashboard + API Org-level UI-only (no API) ADO compensated by Power BI
Security Campaigns Bulk remediation + Autofix Not available GitHub-only feature
Copilot Autofix AI-powered fix suggestions Not available GitHub-only feature
Custom GHCP Agents (platform) Coding agent + agents tab Not on ADO platform Use VS Code agents for ADO repos
Custom GHCP Agents (IDE) VS Code + JetBrains VS Code (for ADO repos) Same agents work in VS Code
Agent Instructions/Prompts .github/ conventions Via VS Code (same files) Agents run locally in IDE
PR Annotations Inline SARIF annotations Build validation annotations Both support inline feedback
Defender for Cloud Integration GitHub connector ADO connector Both feed into MDC
Defender for DevOps GitHub repos visible ADO repos visible Unified view across both
Container Image Scanning Trivy/Grype actions Trivy/MSDO pipeline tasks Same tools available
Accessibility SARIF to AdvSec Code Scanning alerts Code Scanning alerts (ADO) Proven: a11y-scanner visible in ADO
Code Coverage Reporting SARIF + PR comments PublishCodeCoverageResults@2 ADO has native coverage tab
Power BI Security Dashboards Via API (custom build) advsec-pbi-report-ado ADO has dedicated PBI report
FinOps / Cost Analysis GitHub Actions + Azure SDK ADO Pipelines + Azure SDK Same Azure APIs from both
APM Dependency Management apm install + apm audit Works with any Git host APM supports ADO repos
SBOM Generation Anchore Syft / Microsoft SBOM Same tools in ADO pipelines Pipeline-agnostic tools

GHAzDO Capabilities

GitHub Advanced Security for Azure DevOps (GHAzDO) brings core GHAS capabilities to ADO.

Secret Protection

  • Push protection blocks secrets before they enter the repository
  • Secret scanning alerts identify secrets already present
  • Security Overview provides org-level visibility

Code Security

  • CodeQL scanning uses the same engine as GitHub
  • Dependency scanning identifies vulnerable components
  • Third-party tool findings integrate through AdvancedSecurity-Publish@1
  • Security Overview aggregates all findings

PR Annotations

  • Automatic annotations for dependency and code scanning on pull requests
  • Build validation policies enforce scanning before merge

Hierarchical Enablement

  • Enable at organization, project, or repository level
  • Same hierarchical model as GitHub's org and repo-level settings

ADO Pipeline Tasks

The following GHAzDO pipeline tasks replace GitHub Actions equivalents.

Task Purpose GitHub Equivalent
AdvancedSecurity-Codeql-Init@1 Initialize CodeQL analysis github/codeql-action/init@v3
AdvancedSecurity-Codeql-Analyze@1 Run CodeQL analysis github/codeql-action/analyze@v3
AdvancedSecurity-Dependency-Scanning@1 Dependency vulnerability scanning Dependabot / Dependency Review
AdvancedSecurity-Publish@1 Publish custom SARIF results github/codeql-action/upload-sarif@v4
PublishTestResults@2 Publish JUnit test results Third-party actions
PublishCodeCoverageResults@2 Publish Cobertura coverage Third-party actions

Example ADO Pipeline

steps:
  # CodeQL scanning
  - task: AdvancedSecurity-Codeql-Init@1
    inputs:
      languages: 'csharp'
      enableAutomaticCodeQLInstall: true

  - task: AdvancedSecurity-Dependency-Scanning@1

  - task: AdvancedSecurity-Codeql-Analyze@1

  # Custom accessibility scanning
  - script: >
      npx a11y-scan scan
      --url "$(SCAN_URL)"
      --threshold 80
      --format sarif
      --output a11y-results.sarif
    displayName: Run accessibility scan

  - task: AdvancedSecurity-Publish@1
    inputs:
      sarif_file: a11y-results.sarif
    displayName: Publish a11y SARIF

  # Native ADO test and coverage
  - task: PublishTestResults@2
    inputs:
      testResultsFormat: 'JUnit'
      failTaskOnFailedTests: true

  - task: PublishCodeCoverageResults@2
    inputs:
      codeCoverageTool: 'Cobertura'
      summaryFileLocation: '$(Build.SourcesDirectory)/coverage/cobertura-coverage.xml'

Power BI: advsec-pbi-report-ado

The devopsabcs-engineering/advsec-pbi-report-ado repository provides a Power BI report in PBIP format that compensates for ADO's lack of a Security Overview API. This report delivers richer analytics than the native ADO Security Overview UI.

Architecture

Component Detail
Data source ADO Advanced Security REST API at advsec.dev.azure.com (API v7.2-preview.1)
Authentication PAT with vso.advsec scope
Data model Star schema: 1 fact table (Fact_SecurityAlerts) + 5 dimension tables
Parameters OrganizationName + optional ProjectName for multi-org deployment
Pagination Continuation token-based enumeration across all projects, repos, and alerts

Dimension Tables

Table Purpose
Dim_AlertType Alert type classification (dependency, secret, code)
Dim_Date Date dimension for trend analysis
Dim_Repository Repository metadata
Dim_Severity Severity levels
Dim_State Alert states (active, fixed, dismissed)

Key DAX Measures

  • Total Alerts, Active Alerts, Fixed Alerts, Fixed Rate %
  • Critical Active count
  • Mean Time to Fix
  • Alert counts by type: Dependency Alerts, Secret Alerts, Code Alerts

Report Pages

Page Content
Security Overview DevOps Security Findings donut charts, severity distribution, alerts by tool
Alerts by Type Breakdown by dependency, secret, and code alerts
Trend Analysis Alert trends over time with date filtering

Deployment

# Configure for your ADO organization
.\scripts\setup-parameters.ps1 -OrganizationName "yourorg"

# Open in Power BI Desktop
Start-Process AdvSecReport.pbip

# Automated deployment to Fabric workspace
.\scripts\deploy.ps1

Custom Agent Compatibility

Custom GHCP agents have different availability across the two platforms.

Capability GitHub Azure DevOps
Platform-hosted agents (coding agent, agents tab) Available Not available
VS Code agents (chat panel) Available Available (same agents work)
JetBrains agents Available Not tested
Agent instructions and prompts .github/ conventions loaded automatically Loaded via VS Code when developing ADO-hosted code
Organization-wide sharing .github-private repo .github-private (agents work in VS Code for ADO repos)

Note

Custom GHCP agents work in VS Code for ADO-hosted repositories. The same .agent.md files apply regardless of the source control platform. The limitation is that ADO's web platform does not host the coding agent or agents tab.

ADO Advanced Security REST API

ADO Advanced Security exposes a REST API at a separate domain from the standard ADO API.

Property Value
Base URL https://advsec.dev.azure.com/{organization}
API version v7.2-preview.1
Authentication PAT with vso.advsec scope
Endpoints Alerts listing, alert details, alert state updates
Pagination Continuation token-based

This API powers the Power BI report and can be used for custom automation, reporting, and integration with external systems.

Defender for Cloud: Unified View

Microsoft Defender for Cloud provides a unified security posture view across both platforms.

GitHub repos --> GitHub connector --> Defender for Cloud --> Defender for DevOps
ADO repos   --> ADO connector    --> Defender for Cloud --> Defender for DevOps

Both connectors feed findings into the same Defender for Cloud instance, enabling governance teams to view security posture across GitHub and ADO repositories in a single console. Accessibility, coverage, and FinOps findings appear alongside security alerts when published as SARIF to Code Scanning.
