You can use file access management to create a secure intranet. What you're looking for is a Web access management (WAM) product; you can find these products through any of the large identity management vendors.
Web access management systems are designed to provide users with secure access to applications through the Web. To do this, they use directory services for profile and policy storage and administrative interfaces for policies; they also use policy decision points , and agent-based and proxy-based policy enforcement points. Access can be managed directly on the WAM, or it can be integrated into the front-end of a portal implementation. WAMs also let organizations federate domains using the Simple Object Access Protocol (SOAP), which enables users to access resources across domains with a single login (users such as an external vendor who manages an organization's employee benefits).
But be aware, though you didn't mention non-Web-based applications, WAMs do not control access to applications that use proprietary protocols. Other technologies such as provisioning systems and single sign-on (SSO) products are required to secure those environments.
