Managing guest user access is critical for maintaining tenant security. Dormant or unused guest accounts can pose significant security risks if left unchecked, potentially serving as backdoors for unauthorized access or data breaches.

We’ve built a PowerApp-based SaaS solution that leverages Microsoft Graph and AI to continuously scan, retrieve, and analyze all guest users in your Microsoft 365 tenant. It evaluates account activity to detect dormant or inactive external users.

This solution is designed for IT administrators and security teams responsible for tenant governance and external collaboration policies.

Using this app, IT admins gain intelligent, real-time insights into guest user behavior. They can quickly identify inactive accounts, take informed actions such as revoking access or initiating reviews, and establish ongoing controls to enforce least-privilege access — significantly enhancing the security posture of the organization.
