What is Granular Delegated Admin (GDAP)?

Granular Delegated Admin Privileges (GDAP) is Microsoft’s modern security framework that allows Independent Software Vendors (ISVs) and Managed Service Providers (MSPs) to support customer environments with specific, time-limited, and role-based permissions—instead of broad, permanent access.

This shift ensures stronger security, customer control, and compliance with Microsoft’s Zero Trust model.

Why GDAP is the Security Best Practice

  1. Principle of Least Privilege (PoLP)

    • ISVs are granted only the permissions required to complete their tasks.

    • Reduces risks from overprivileged accounts, which are prime cyberattack targets.

  2. Time-Bound Access Control

    • Permissions can be issued for defined durations.

    • Eliminates permanent “standing” access and lowers the attack surface.

  3. Reduced Insider Threats

    • Role-based access ensures only the right people can perform specific actions.

    • Mitigates risks from compromised or malicious accounts.

  4. Minimized Supply Chain Risks

    • ISVs cannot move freely within a customer’s environment without explicit approval.

    • Reduces exposure to third-party breaches (e.g., SolarWinds-style attacks).

  5. Alignment with Microsoft’s Secure Access Model

    • Supports Microsoft’s Zero Trust security principles.

    • Integrates with Secure Admin Workstations (SAW) and Privileged Identity Management (PIM).

  6. Enhanced Auditability & Monitoring

    • Every administrative action is logged.

    • Customers can track, review, and revoke access at any time.

  7. Customer-Centric Security

    • Customers retain complete control over who can access their environment.

    • Facilitates compliance with industry standards (GDPR, HIPAA, ISO 27001).

How GDAP Works

  1. ISVs request access with defined scope and timeframe.

  2. Customers review and approve based on security policies.

  3. Microsoft Entra logs and monitors all privileged activities.

  4. Access automatically expires when the approved window ends.

Key Benefits for Customers

  • ✅ Stronger Security – Minimizes attack surface by limiting access.

  • ✅ Greater Transparency – Customers have full visibility and control.

  • ✅ Regulatory Compliance – Supports data protection standards.

  • ✅ Risk Reduction – Protects against credential theft and phishing.

  • ✅ Operational Efficiency – ISVs only access what they need, when they need it.

Conclusion

Granular Delegated Admin (GDAP) is more than a security feature—it’s a best practice for all customers on the Microsoft platform. By adopting GDAP, ISV partners can deliver services securely, while empowering customers with greater transparency, stronger controls, and reduced risk exposure.
