Cross Identity vs. Microsoft Entra
Identity Security: Bundle vs Infrastructure
Executive Summary
Identity has become the primary control plane for modern enterprise security. As organizations expand across cloud, hybrid, and SaaS environments, every user, workload, service account, and privileged role represents both an operational necessity and a potential risk surface.
Most enterprises begin their identity journey with Microsoft Entra. Its deep integration with Microsoft 365 and Azure, combined with broad identity and access capabilities, makes it a natural default choice. For organizations with primarily Microsoft-centric environments and basic access control needs, this approach is often sufficient.
However, as identity programs mature, security leaders increasingly encounter a structural limitation: identity capabilities exist, but they do not operate as a single security system. Governance, privileged access, cloud entitlements, risk detection, and compliance are delivered through multiple services that must be integrated, orchestrated, and operated independently. Over time, this creates operational complexity, delayed enforcement, and fragmented risk visibility.
This report examines a fundamentally different approach.
Cross Identity was designed as a converged identity security infrastructure, not a bundle of identity tools. All core identity functions—Access Management, Identity Governance, Privileged Access Management, Cloud Infrastructure Entitlement Management, Identity Threat Detection and Response, Identity Security Posture Management, and Data & Privacy Compliance—operate on a single architectural core with one risk engine and one control plane.
The distinction explored in this report is not about feature parity. It is about architecture.
- Microsoft Entra represents an identity bundle model, optimized for ecosystem integration and breadth.
- Cross Identity represents an identity infrastructure model, optimized for unified control, real-time risk enforcement, and operational simplicity at scale.
This document provides an architectural comparison of these two approaches, examining how design choices impact security outcomes, operational efficiency, and enterprise readiness in hybrid and multi-cloud environments.
The objective is not to displace one platform with another, but to help organizations determine which identity model aligns with their security maturity, operating reality, and long-term risk posture.
Understanding Microsoft Entra
Microsoft Entra is Microsoft’s enterprise identity platform, evolved from Azure Active Directory and positioned as a foundational component of Microsoft’s broader security and productivity ecosystem. It plays a central role in how organizations authenticate users, control access to applications, and manage identities across Microsoft cloud services.
At its core, Microsoft Entra delivers robust identity and access management capabilities, including authentication, conditional access, single sign-on, and lifecycle management for workforce and external identities. Its tight integration with Microsoft 365, Azure, Windows, and the broader Microsoft security stack makes it a natural choice for organizations operating primarily within the Microsoft ecosystem.
Over time, Microsoft Entra has expanded to include additional identity-related capabilities, such as identity governance, privileged identity management, and cloud entitlement visibility. These capabilities are delivered through distinct services—often licensed and operated separately—but presented under the Entra product family.
This design reflects Entra’s historical evolution rather than a single, unified architectural blueprint. Identity governance, privileged access, cloud permissions, threat detection, and compliance are provided through multiple engines that are connected through integrations and shared portals, rather than through a single converged core.
As a result, Microsoft Entra functions best as an identity platform—providing broad coverage and strong ecosystem alignment—rather than as a fully converged identity security infrastructure. Governance decisions, privilege controls, and risk signals may originate in different systems and require orchestration across tools to achieve end-to-end enforcement.
For many organizations, this model is effective and appropriate. Microsoft Entra offers a familiar operational experience, strong native capabilities, and significant value when identity security requirements are largely contained within Microsoft-managed environments.
However, as identity security requirements expand—particularly across hybrid, multi-cloud, and non-Microsoft systems—the architectural implications of a multi-engine identity model become more pronounced. These implications form the basis for the comparisons explored in the following sections of this report.
