Microsoft Entra Identity & Access Management Architecture

Zero-Trust

Zero-trust identity architecture with real-time conditional access signal evaluation, adaptive step-up MFA, and unified workforce and customer identity segregation.

The Challenge

Vulnerable Identity Boundaries and Credential Attacks

Fragmented user directories, weak legacy authentication protocols, and unmanaged external user access represent the primary vector for enterprise credential stuffing attacks and compliance failures in Australian organisations.

Monolithic user databases vulnerable to SQL injection and credential stuffing
Inconsistent MFA enforcement across legacy VPNs and SaaS applications
Lack of automated employee onboarding and offboarding lifecycle governance
Complex consumer identity friction leading to customer registration drop-off

How AgenorIT Delivers Microsoft Entra Identity & Access Management

AgenorIT designs and implements secure Microsoft Entra ID and External ID architectures. We migrate legacy monolithic user stores to cloud-native CIAM, configure risk-based Conditional Access policies, establish privileged identity management (PIM), and eliminate credential exposure across customer and workforce systems.

Architecture Decision Guide

Evaluating Your Technical Approach

Migration Strategies: Lift-and-Shift vs PaaS Replatform vs Cloud-Native Refactor
Architectural Dimension	Lift & Shift (IaaS)	PaaS Replatform	Cloud-Native Refactor (Agenor)
Infrastructure Management	High; virtual machine OS patching and storage management remain	Low; managed runtimes like Azure App Service and Azure SQL	Zero server overhead; serverless event-driven containers and managed data APIs
Scaling & High Availability	Vertical VM resizing requiring planned maintenance windows	Automatic horizontal instance scaling based on HTTP request queues	Instant sub-second concurrency scaling to zero with multi-region replication
Operational Cost Profile	Continuous compute reservation costs regardless of actual traffic	Pay-per-instance tiering with predictable monthly allocation	Fine-grained consumption billing tied directly to business transaction volume
Security & Isolation	Perimeter firewall dependent on host OS hardening and agent maintenance	Integrated Microsoft Entra authentication and managed identity tokens	Zero-Trust network segmentation, Private Endpoints, and automated Key Vault secrets

Verified Engineering Impact

50,000+ Identities Migrated to Microsoft Entra

Client Context

Australian consumer platform facing credential stuffing threats and legacy monolithic database risks.

Architectural Outcome

100% breach remediation, zero credential stuffing incidents post-launch, and 38% increase in consumer onboarding with native Apple & Google SSO.

Read Entra CIAM Case Study

When dedicated CIAM re-architecture is not required

If your organisation only requires basic single sign-on for a team of fewer than 20 internal users across standard Microsoft 365 apps with no custom applications or external customer portals, out-of-the-box Microsoft 365 security defaults are sufficient without custom engineering.

Technical FAQ

Microsoft Entra Identity & Access Management — Technical FAQ

Direct engineering answers to common technical and commercial queries.

Microsoft Entra ID is designed for internal workforce identity, managing employees, company devices, and internal enterprise applications. Entra External ID (formerly Azure AD B2C) is designed for customer-facing applications (CIAM), supporting millions of external users with social logins and custom registration workflows.

We utilize a seamless "just-in-time" migration pattern. When a user logs in for the first time, our custom flow validates their credentials against the legacy database and transparently migrates their secure password hash into Microsoft Entra without forcing an unnecessary password reset email.

Conditional Access enforces real-time signals: requiring compliant managed devices, evaluating user and sign-in risk from Microsoft Threat Intelligence, enforcing FIDO2/Passkey phish-resistant credentials, and requiring continuous session re-evaluation.

Yes. We implement MSAL (Microsoft Authentication Library) SDKs with PKCE (Proof Key for Code Exchange) flows across native Swift/iOS and Kotlin/Android applications for secure, modern mobile authentication.

Break-glass accounts are emergency access administrator accounts excluded from standard Conditional Access and MFA policies, ensuring you never get locked out of your Azure tenant during widespread authentication outages or misconfigurations.
