With the success of single sign-on (SSO) inside the enterprise, users are calling for interoperability outside of the enterprise's security domain to outsourced services, including business process outsourcing (BPO) and software as a service (SaaS) providers, and trading partners, as well as within the enterprise to affiliates and subsidiaries.

While the business demands that employees are able to traverse the Internet with highly-sensitive data, the connection has to be secure to protect the user, enterprise and service provider--enter secure Internet SSO. Written for anyone interested in understanding how secure Internet SSO works, this white paper explores the limitations of current SSO implementations outside of a single security domain (including identity and access management systems and open source development) and introduces standalone secure Internet SSO as a solution.
