Cross-Tenant Access Policy Review for Retail & E-Commerce

How retail & e-commerce organizations should implement EXT-05 for Microsoft 365 security and compliance.

For retail & e-commerce companies using Microsoft 365, cross-tenant access policy review is a security priority. This guide explains how EXT-05 helps retail & e-commerce organizations protect their identity infrastructure while meeting industry-specific compliance mandates.

Why Retail & E-Commerce Organizations Need This Control

Retail & E-Commerce organizations face specific regulatory requirements including pci-dss, soc2, 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.

Industry-Specific Considerations

When implementing EXT-05 in a retail & e-commerce environment, consider:

  • **Regulatory requirements**: pci-dss, soc2, cis may mandate specific configurations
  • **Risk tolerance**: Retail & E-Commerce organizations typically have moderate to low risk tolerance
  • **Audit frequency**: Plan for regular compliance reviews
  • **Documentation**: Maintain detailed records for regulatory inspections

How to Configure

EXT-05 requires the following configuration:

  • Default cross-tenant access policy is not overly permissive
  • Partner-specific configurations exist for known collaborators
  • Inbound and outbound B2B access is explicitly controlled
