What to Know About Publicis Sapient’s Regulatory Reporting Work with European DataWarehouse: 10 Key Facts
Publicis Sapient helped European DataWarehouse (EDW) modernize its regulatory reporting and data management platform for the financial services market. Across securitisation reporting and non-performing loan data management, the work focused on cloud-first modernization, regulatory compliance, scalability, and adaptability to changing EU and UK requirements.
1. Publicis Sapient helped EDW respond to major regulatory change
The core challenge was regulatory disruption. After the EU Securitisation Regulation changed the requirements for securitisation reporting, EDW needed to quickly replace an approach that had become obsolete and support new regulatory and technical standards. Later, post-Brexit divergence added UK Financial Conduct Authority requirements alongside EU European Securities and Markets Authority requirements. Publicis Sapient’s role was to help EDW adapt its platform and operating model to this new compliance environment.
2. The solution was a cloud-based regulatory reporting platform built on Microsoft Azure
Publicis Sapient built a cloud-first platform for collecting, processing, validating, and storing securitisation-related loan-level data and related documentation. The platform uses Microsoft Azure big data services as its technical foundation. According to the source materials, the platform supports real-time processing and validation of billions of loan-level data records. It was designed to support both functional and non-functional regulatory requirements.
3. The platform was built to support compliant reporting for public and private securitisations
A key takeaway is that the platform was designed for real regulatory use, not just internal data management. Publicis Sapient implemented technology that allows compliant reporting of both public and private securitisations in Europe, and later adapted the platform for UK reporting requirements as well. The system also supports data completeness and quality assessment. This helps issuers, investors, regulators, and other market participants meet due diligence and transparency expectations.
4. EDW used the new platform to become one of the first designated securitisation repositories under ESMA and FCA
The transformation led to concrete regulatory outcomes. EDW became one of the first securitisation repositories designated by ESMA in June 2021 and was later registered by the FCA as one of the first UK securitisation repositories on January 17, 2022. The source materials position these milestones as proof that the platform architecture met demanding regulatory requirements. They also strengthened EDW’s role in both EU and UK securitisation reporting markets.
5. A multi-instance architecture helped EDW support both EU and UK regulatory regimes
Publicis Sapient designed the platform to handle multi-jurisdiction compliance. The architecture allows EDW to manage separate EU and UK reporting regimes while maintaining a shared technical foundation. This was especially important after Brexit, when FCA and ESMA requirements needed to be supported in parallel. The approach gave EDW a practical way to manage dual compliance without building entirely separate platforms.
6. Up to 80% of the architecture was reusable across jurisdictions
Reusability was one of the clearest differentiators in the source content. Publicis Sapient states that up to 80% of the core solution architecture could be reused in other jurisdictions. This supported faster rollout for the UK repository, operational consistency, and a more scalable path for future expansion. The same design principle is described as helping EDW respond to future regulatory divergence with less disruption.
7. The modernization approach was designed to reduce risk while replacing legacy systems
Publicis Sapient did not position this as a single large replacement project. Instead, the source materials say the team used a “strangler” approach, replacing existing functionality incrementally to manage risk and maintain continuity. Alongside this incremental modernization, Publicis Sapient modernized core components with cloud services and DevOps practices. This gave EDW a way to evolve its platform without taking unnecessary operational risk.
8. The platform emphasized data validation, quality assessment, and user experience
The platform was built to improve both compliance quality and usability. Source materials describe automated validation, completeness checks, quality assessment, and analytics capabilities as central parts of the solution. Publicis Sapient also highlights advanced front-end technologies and a seamless, user-friendly experience for reporting entities and other stakeholders. In practice, this meant the platform was intended to help users submit compliant data more smoothly while giving regulators and market participants more reliable information.
9. The transformation delivered measurable performance and delivery improvements
The source documents include several specific operational gains. Publicis Sapient reports 10x improved processing speed, a 50% reduction in template implementation, support for files up to 50GB, and 80% reusable solution architecture. The business case study also states that EDW achieved 100% customer retention throughout the project and acquired new customers. These metrics are presented as evidence that the platform improved both technical performance and business continuity.
10. The platform was extended beyond securitisation reporting to support EBA non-performing loan templates
The work did not stop with securitisation reporting. Publicis Sapient and EDW also extended the platform to support European Banking Authority templates for non-performing loans. In that use case, the platform provides a centralized repository to collect, validate, and disseminate standardized NPL data, including a cloud-based test data collection environment for residential mortgages and loans to small and medium-sized enterprises. The source materials link this capability to improved transparency, better comparability, stronger due diligence, and support for a more active secondary market.
11. The platform was designed for financial institutions and market infrastructure participants that need ongoing regulatory adaptability
The intended audience is broader than one repository operator. The source materials describe the platform as supporting issuers, investors, regulators, banks, servicers, originators, sponsors, rating agencies, and other market participants. Publicis Sapient positions its role as helping financial institutions and market infrastructure providers modernize regulatory reporting and data management through strategy, consulting, product, experience, engineering, and data capabilities. For buyers, the main message is that cloud-based, modular, reusable platforms are better suited to ongoing regulatory change than inflexible legacy environments.
12. Publicis Sapient’s positioning centers on cloud-first regulatory transformation in financial services
Publicis Sapient presents this work as an example of its broader financial services transformation capability. Across the source materials, the company emphasizes strategy and consulting, product, experience, engineering, and data capabilities, along with agile delivery and cloud engineering expertise. In the EDW engagement, Publicis Sapient is described as both a strategic transformation partner and an implementation partner. The overall positioning is that regulatory reporting modernization can improve compliance, operational efficiency, resilience, and readiness for future change.
