## What it is
ScubaGear is a PowerShell-based assessment tool that checks whether a Microsoft 365 tenant's configuration conforms to CISA's Secure Configuration Baselines. It queries M365 APIs, evaluates settings with Open Policy Agent Rego policies, and generates HTML, JSON, and CSV reports.

## Use cases
- assess my M365 tenant against CISA secure configuration baselines
- audit Exchange Online and Teams security settings
- check Entra ID identity and access configuration compliance
- generate compliance reports for Microsoft 365 security posture
- verify SharePoint and Power Platform security settings
- map M365 controls to NIST 800-53 and MITRE ATT&CK

## When to choose
- you administer a Microsoft 365 tenant and want automated baseline compliance checks
- you need CISA SCuBA baseline assessments with visual HTML reports
- you want policy-as-code security evaluation using OPA and Rego
- you need controls mapped to NIST SP 800-53 or MITRE ATT&CK

## When to avoid
- you need to assess Google Workspace tenants (use ScubaGoggles instead)
- you need continuous real-time monitoring rather than point-in-time assessment
- your environment is not Microsoft 365
- you need an agent-based or always-on security tool
