## 1.2. Federate Enabling Applications

The expertise and cost required to add SAML2 support to web applications is a problem for many businesses. Those businesses not moving to a standard for exposing their applications to their customers see increased cost and maintenance due to the complexity of one-off proprietary integrations. They may also see a loss of business to those customers requiring a Federation standard for authentication. Sometimes, deploying a full access mangaement solution just to federate a few applications is is too complex and costly, and building out their own solution by modifying their applications is just not possible.

OpenIG Federation Gateway allows businesses to add SAML2 support to their applications with little to no knowledge of the standard. In addition, there is no need to modify the application or install any plugin or agent on the application container.
