Cross-Tenant Access Policy Review for Technology & Software

How technology & software organizations should implement EXT-05 for Microsoft 365 security and compliance.

Technology & Software 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 Technology & Software Organizations Need This Control

Technology & Software 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.

Industry-Specific Considerations

When implementing EXT-05 in a technology & software environment, consider:

  • **Regulatory requirements**: soc2, iso27001, cis may mandate specific configurations
  • **Risk tolerance**: Technology & Software organizations typically have moderate to low risk tolerance
  • **Audit frequency**: Plan for regular compliance reviews
  • **Documentation**: Maintain detailed records for regulatory inspections

Implementation Steps

To implement EXT-05 in your Microsoft 365 environment:

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

TrueConfig can automatically remediate this control with one click.

Technology Compliance Requirements

Technology organizations must comply with these frameworks, all of which address cross-tenant access policy review:

Why This Control Matters for Technology

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.

Common threats in technology & software:

  • Source code theft and IP exfiltration
  • Supply chain attacks through dependencies
  • Credential compromise in CI/CD pipelines

For technology & software organizations, EXT-05 is a key component of a compliant Microsoft 365 security posture. TrueConfig helps you implement and maintain this control while meeting industry-specific requirements.
