Ralf Kempf, CTO SAST SOLUTIONS, and his team have already guided many enterprises through their migration to SAP S/4HANA. He talked about his recipes for success in an interview with Ulrich Parthier, publisher of it management magazine.
Excerpts from the interview are provided below.

The transition of the business world to SAP S/4HANA is picking up speed: that’s why every company should start preparing an end-to-end migration strategy for the new SAP system. It is essential that this strategy consider security aspects, as well, to avoid ending up sitting on millions in subsequent costs. The solution is Threat Intelligence.
The upgrade from SAP ERP to SAP S/4HANA also involves a changeover to a new technology. This offers new possibilities thanks, to the increased speed of the SAP HANA in-memory database, as well as an improved user experience through the new FIORI UI. At the same time, however, the implementation of SAP S/4HANA also presents many enterprises with the difficult challenge of planning and executing their migration projects correctly: existing processes and role concepts have to be reconsidered.
The SAP S/4HANA software suite represents a cutting-edge cornerstone for the digitalization of enterprises and is increasingly being used by both SMEs and large corporations. However, the implementation of and migration to SAP S/4HANA also entail increasing complexity in system administration and management. Our specialized software tools enable you to master this project successfully.
Before migrating old ERP authorizations to the new S/4HANA system, project owners must ask countless, but crucial questions. However, many companies leave security and compliance for last. This is a mistake: These aspects should be included in the migration strategy right from the get-go.
Structured security planning and streamlined authorizations are just two elements of protecting SAP systems against cyberattacks and manipulation. In this interview, Ralf Kempf (CTO SAST SOLUTIONS at akquinet AG) talks about the pitfalls to avoid during an SAP S/4HANA migration and what you can do to use SAP S/4HANA securely.
SAP systems require special attention when it comes to their security and this is no longer news to anyone. More often than not, the ERP systems supplied from Walldorf in Baden-Württemberg store some of the most crucial and sensitive company data. That said, what is the best approach to achieving the optimum level of security? A security audit would fit the bill!
Started with two modules in 2006, the SAST SOLUTIONS portfolio now comprises a comprehensive combination of software, consulting and service, and offers a holistic solution for safeguarding SAP systems. In this interview, Managing Director Bodo Kahl talks about the topics that concern himself as well as the entire industry, and describes the qualities that characterize a good service provider for SAP security and compliance today.
According to recent investment reports from the German SAP User Group (DSAG), up to 80 percent of the companies it surveyed intend to migrate their SAP systems to S/4HANA in the next several years. Certainly a bold endeavor. To minimize internal effort, the recommendation is to eliminate legacy issues – for example ABAP custom code – before the migration takes place.
C/4HANA is the name of the newest product in the SAP portfolio. The company based in Walldorf, Germany, promises nothing less than a revolution of customer experience. But is C/4HANA secure? And what does “C/4HANA” mean, anyway?
