Third-Party Enterprise App Permissions for Professional Services & Consulting
How professional services & consulting organizations should implement APP-06 for Microsoft 365 security and compliance.
For professional services & consulting companies using Microsoft 365, third-party enterprise app permissions is a security priority. This guide explains how APP-06 helps professional services & consulting organizations protect their identity infrastructure while meeting industry-specific compliance mandates.
Why Professional Services & Consulting Organizations Need This Control
Professional Services & Consulting organizations face specific regulatory requirements including soc2, iso27001, cis. The APP-06 control helps address these requirements by:
- Third-party enterprise apps with elevated permissions are identified and reviewed
- External vendor apps with Directory.ReadWrite.All, Mail.ReadWrite.All are flagged
- Each third-party app with elevated permissions has documented vendor assessment
- Quarterly review of third-party app permissions is conducted
Third-party enterprise apps are applications from external vendors that you consented to but do not control. These apps pose supply chain risk - a compromised vendor could access your tenant data. Review vendor security certifications and limit permissions to minimum necessary.
Industry-Specific Considerations
