LShift have been providing consultancy and development services to T-Mobile for several years now.
We currently manage a SOA security gateway that protects the central business systems in Germany and is used by internal operating companies to access services such as billing and call provisioning. It logically consists of an IBM Datapower XS40 dedicated hardware XML firewall to enforce security policy, and an LDAP server.
The project has comprised establishing rigorous development practises, improving the overall quality control and evolving the system for use in other platforms.
