For Deutsche Post AG, punkt.de has developed and implemented a central web portal, which supports the around 13,000 partner stores in their customer service. The platform with SAP integration for up to 35,000 users comprises eLearning offers, legally relevant examination tests, a list of frequently asked questions and a search engine. Due to the rights system, certain users can only access specific information. A single sign-on allows easy switching between different applications, while a demilitarized zone protects the portal against hackers. Substantial changes in the CMS and the new TYPO3 framework concerning authentication prevent confidential information from reaching the internet. The result of a satisfaction survey, which was conducted at the end of the project, shows that the partner stores of Deutsche Post are convinced by the portal: three times more employees than in the years before took part in the survey and the portal itself received 8.1 out of 10 points.
