Modernizing Legacy SSO with Microsoft Entra, Protect On-Prem Apps Without Rewriting Code

Many enterprise applications still rely on legacy identity platforms such as SiteMinder or PingFederate. Rewriting these applications to support modern authentication can take years of engineering effort. what if you could modernize authentication using Microsoft Entra without changing the application code at all ? Although many organizations have moved toward cloud-native architectures, critical legacy applications remain in many enterprise environments, hosted on platforms such as Oracle WebLogic, Tomcat, or Apache. Many of these applications are complex, tightly coupled systems, where modernizing microservices is not straightforward and can take a long time due to their complexity and security concerns. These applications were designed to work with previous identity solutions, such as CA SiteMinder or PingFederate . A significant number of these applications use HTTP header-based authentication rather than more modern protocols such as OAuth2, OpenID Connect, and SAML. Rewriting leg
