D365 Customer Engagement (CE) Security Introduction

Security in Dynamics 365 Customer Engagement (CE) is a foundational aspect of any implementation. It governs how data is accessed, who can perform which actions, and how organizations maintain compliance, confidentiality, and control over business-critical information.

Whether you're building a CRM system for a small team or deploying Dynamics 365 across multiple countries and departments, having a solid understanding of the platform’s security model is crucial. It ensures that users see only what they need, administrators can manage permissions effectively, and data integrity is maintained at all times.

In this article, we'll explore the key components of the Dynamics 365 CE security model, including Business Units, Security Roles, Teams, and advanced mechanisms like Field Security and Hierarchical Access. We'll also share best practices and real-world scenarios to help you design a secure and scalable solution.

Core Components of the Security Model

Dynamics 365 CE uses a layered security model that combines organizational structure, user roles, and record-level permissions to control access. Understanding how these layers interact is essential for designing a secure and efficient CRM system.

The core components include:

1. Business Units – define the organizational boundaries for data access.

2. Security Roles – determine what users can do with the data.

3. Teams – provide flexibility in access management across units.

4. Field-Level Security – restrict visibility to sensitive fields.

5. Record Sharing – allows fine-grained access on a per-record basis.

Each of these elements contributes to the overall security posture and enables organizations to implement both standard and complex access control scenarios. Let's break down each component.
