The document discusses the growing success of the Software as a Service (SaaS) market and the problem of "shadow IT" or uncontrolled adoption of SaaS applications by employees. It notes that the average company uses around 20 SaaS apps, which broadens security risks. The document provides recommendations for IT staff to address shadow IT, such as establishing inclusive SaaS policies, communicating policies clearly, and implementing identity and access protection standards like Security Assertion Markup Language (SAML). For developers, it recommends focusing on making apps easier for customers to manage and more enterprise-friendly by supporting SAML single sign-on.
