About
Sentinel Identity is an independent technical blog focused on Microsoft identity operations.
The site focuses on Microsoft Entra ID, Conditional Access, authentication protocols, DNS, tenant hardening, and operational troubleshooting for administrators, security teams, and cloud engineers.
The goal is to publish content that helps readers understand how identity systems work in practice: what a control does, what happens in the backend, why a configuration fails, and how to reason about remediation without relying on shallow summaries.
Content is written as long-form technical material and links official Microsoft documentation where product behavior, configuration requirements, or support boundaries need to be validated.
Topics
Microsoft Entra, Conditional Access, MFA, passkeys, hybrid identity, authentication protocols, custom domains, Exchange Online DNS, and tenant security posture.
Audience
Identity administrators, Microsoft 365 engineers, architects, consultants, and readers who need implementation-level explanations rather than light overview content.
Approach
Articles are written as explanatory technical documents, with the emphasis on architecture, policy, operations, and troubleshooting rather than republishing generic summaries.
