Hybrid identity refers to an IT environment that combines on premises identity and access management systems with cloud based identity and access management services. This approach allows users to maintain a single digital identity across both local and cloud resources, simplifying access and improving security posture. In practice, it enables seamless authentication and authorization for applications and data residing in different locations. Hybrid identity is crucial for modern organizations that leverage both traditional infrastructure and cloud platforms, ensuring consistent user experience and centralized control. For instance, an employee might use their corporate Active Directory credentials to log into both internal servers and a Microsoft 365 application. This differs from a purely cloud based identity system which relies solely on external providers for authentication. Understanding hybrid identity is essential for cybersecurity professionals and appears on exams like CompTIA Security+ and CISSP.
