Cross-Tenant Access Policy Review for Professional Services & Consulting
How professional services & consulting organizations should implement EXT-05 for Microsoft 365 security and compliance.
Professional Services & Consulting organizations face unique security challenges when managing Microsoft 365 environments. The EXT-05 control (Cross-Tenant Access Policy Review) is particularly important for this sector due to soc2 and iso27001 requirements.
Why Professional Services & Consulting Organizations Need This Control
Professional Services & Consulting organizations face specific regulatory requirements including soc2, iso27001, cis. The EXT-05 control helps address these requirements by:
- Default cross-tenant access policy is not overly permissive
- Partner-specific configurations exist for known collaborators
- Inbound and outbound B2B access is explicitly controlled
Permissive cross-tenant defaults allow any external organization to collaborate with your tenant. Restricting defaults and configuring partner-specific policies ensures only approved organizations can access your resources.
