Future-ready banking and insurance

T-Systems supports financial institutions across four key areas: sovereign cloud and services aligned with regulatory requirements, including DORA; AI, data and intelligent automation; core and platform modernization, from Mainframe to RISE with SAP and ServiceNow; and cybersecurity, including preparation for emerging post-quantum risks. With services delivered through German and European operations, T-Systems helps banks, insurers and asset managers modernize their IT while addressing evolving regulatory requirements.

DORA requires banks, insurers and other financial entities to manage ICT risk, report incidents, test operational resilience and oversee ICT third-party providers. T-Systems supports these areas through governance, risk and compliance services, cloud and managed platform offerings that can support DORA-related contractual requirements such as audit rights, exit planning and subcontractor transparency, and cyber defense services including 24/7 detection, response and resilience testing. Our German-language whitepaper “DORA Entschlüsselt”, provides further detail on our approach.

T Cloud Public is operated by T-Systems International GmbH, a Deutsche Telekom AG company headquartered in Frankfurt, Germany, exclusively from data centers in Germany (Biere, Magdeburg), the Netherlands (Aalsmeer, Almere) and – as a separate, self-contained Swiss community cloud for Swiss customers – Switzerland (Zollikofen, Bern). Operations and maintenance are performed exclusively by European Telekom/T-Systems personnel who are subject solely to European jurisdiction, and as a German company T-Systems is not subject to the US CLOUD Act. The platform's security controls are independently attested through BSI C5 Type 2, SOC 1 Type 2 and SOC 2 Type 2 audit reports. Customers retain control of their encryption keys via the Key Management Service, which is based on FIPS 140-2 Level 3 certified Hardware Security Modules and supports customer master keys as well as bring-your-own-key (BYOK). Privileged access, segregation of duties and logging controls are evidenced in the C5/SOC 2 audit reports, and T Cloud Public employees have no access to customer environments. This makes the platform suitable for regulated industries such as banking and insurance, including AI training and inference on a broad range of GPU resources.

Yes, when data, models and operations stay under European control. T-Systems AI Foundation Services give you access to more than 15 open and closed source language models through one API, hosted on sovereign infrastructure and compliant with GDPR. Governance features such as logging, model documentation and audit trails support EU AI Act obligations for high-risk use cases like credit scoring or claims decisions. Data platform and data quality services make sure the models work on trusted data.

Yes. Insurers face the same pressure as banks: ageing policy administration and claims systems, high maintenance costs and slow product launches. T-Systems modernizes mainframe and legacy estates, migrates SAP landscapes to RISE with SAP on German private cloud, runs ServiceNow as a managed platform for IT and business workflows, and builds digital front ends such as customer apps. Barmenia, for example, launched an invoice app and a medical consultation app with T-Systems.

In two ways. First, we help you assess where long-lived encrypted data is exposed to harvest-now-decrypt-later attacks and plan the migration to post-quantum cryptography. Second, Quantum as a Service gives your quant, actuarial and risk teams secure cloud access to quantum and quantum-inspired computing from partners such as IBM, IQM and AQT for portfolio optimization and risk modelling, without building your own infrastructure.
