Login Alliance

After successful project cooperation, the two specialists Syntlogo and intension recognised the new requirements in the IAM area. To implement this, they founded an initiative: the IAM network Login Alliance.

The Login Alliance offers everything that is necessary for the successful implementation of CIAM applications: consulting, project services and Login-Master; hence a comprehensive, flexible and affordable B2B solution for web portals and internet applications. If on premises or in the cloud.

For cloud environments, the Login Alliance has answers to previously unresolved issues relating to the assignment and control of access rights. Because Login-Master manages access rights automatically, just-in-time and without any provisioning. And a global user administration is the top priority. With data synchronisation in real-time, companies and organizations can greatly reduce their manual effort and save costs in their identity management processes.
