Knowledge retention & operational resilience for critical systems
For decades, central business processes at many German banks and financial service providers have been based on traditional core systems, often relying on mainframe infrastructures, COBOL code, and batch-based processing logic. With the retirement of experienced specialists due to age, the operational stability of these systems is coming into focus: knowledge is often insufficiently documented, processes are heavily dependent on individuals, and system changes carry a high risk of production disruptions and regulatory audits. The challenge for companies is to ensure that their business processes remain stable and secure in the long term, while at the same time enabling them to adapt to new market conditions and regulatory requirements.

Service components:
Legacy modernization & mainframe transformation consulting
The modernization of legacy IT is not a question of “moving away from the mainframe,” but rather a question of secure, controlled evolution. Mainframe systems remain indispensable today due to their performance, reliability, and regulatory stability. At the same time, there is growing pressure to connect these systems with modern architectures, API-enabled components, and agile development processes.
