Our Competencies
Choose the area that fits your requirements
Ensure complete FIDA compliance through professional audit and reporting services. We support you in implementing monitoring systems, preparing for regulatory examinations, and maintaining continuous compliance documentation.
The EU Financial Data Access regulation (FIDA) requires banks, insurers and financial institutions with 250+ employees to share customer data with licensed third parties via standardised APIs. A structured compliance programme is essential to meet FDSS membership, consent management and real-time data provision requirements on time.
The FIDA regulation requires data holders to provide every customer with a permission dashboard – an online interface for monitoring and managing all granted data sharing permissions. We develop consent management systems that combine granular permissions, real-time overviews and simple revocation functions meeting both FIDA and GDPR requirements.
As a specialized FIDA consulting partner, we support financial institutions with the technical implementation of the Financial Data Access regulation. From API architecture and consent management to scheme integration, we offer proven consulting services for sustainable FIDA compliance.
A comprehensive FIDA gap analysis is the foundation for successful compliance. We systematically assess your current position, identify critical implementation gaps and develop a tailored roadmap for FIDA-compliant transformation.
Successful implementation of the Financial Data Access Regulation requires precise technical execution and strategic implementation planning. We accompany you from system architecture through to go-live with proven implementation methodologies.
Specialized incident response strategies for FIDA compliance incidents. We support you in the rapid and effective handling of data breaches, API outages, and regulatory compliance incidents in the FIDA context.
A structured assessment of your FIDA readiness provides the foundation for successful compliance and strategic market positioning. We evaluate your current position across six dimensions, identify concrete action areas and develop a prioritized implementation roadmap with quick wins.
The Financial Data Access Regulation (FIDA) defines new regulatory standards for data access in the financial sector. We support you in achieving full compliance implementation and strategic positioning within the new regulatory landscape.
Professional sandbox environments and comprehensive testing services for FIDA implementations. From API validation to compliance testing — we ensure that your FIDA solution is production-ready and regulatory compliant.
The Financial Data Access regulation requires robust frameworks for third-party risk management and vendor selection. We develop strategies for secure and FIDA-compliant data sharing partnerships — from FISP licensing verification through vendor due diligence to ongoing risk monitoring.
The Financial Data Access Regulation requires comprehensive employee qualification and organizational awareness. We develop tailored training programs that optimally prepare your teams for FIDA requirements and ensure sustainable compliance success.
Frequently Asked Questions about FIDA API Architecture and Security
What API security standards does the FIDA regulation mandate?
The FIDA proposal names no protocol at all. Article
10 obliges the Financial Data Sharing Schemes to agree common standards for customer data and for the technical interfaces, so the concrete specification is set in the scheme and in delegated acts rather than in the regulation itself. The standards the market is converging on are OAuth 2.0 with PKCE (Proof Key for Code Exchange), OpenID Connect, TLS 1.3, Strong Customer Authentication (SCA) and ISO‑20022 compliant data formats. What the proposal does contain is the duty to make customer data available continuously, as well as the interplay with operational resilience under DORA.
What is a zero-trust model for FIDA APIs?
A zero-trust model for FIDA APIs means no API access is automatically trusted. Every request is authenticated and authorized regardless of network location. This includes token validation on every call, micro-segmentation, continuous monitoring and defense-in-depth strategies with multiple security layers.
How does FIDA API architecture differ from PSD2 interfaces?
FIDA goes far beyond PSD2: instead of just payment data, FIDA covers all financial products including loans, insurance, pensions and prospectively crypto assets. The API architecture must support Financial Data Sharing Schemes (FDSS), provide granular consent management and scale with significantly more data types and actors.
What role does an API gateway play in FIDA compliance?
The API gateway is the central security layer for FIDA-compliant interfaces. It handles rate limiting, token validation, request routing, logging for audit trails and policy enforcement. For FIDA, the gateway must additionally perform consent checks and ensure only authorized FISPs access approved data.
How long does implementing a FIDA-compliant API architecture take?
Depending on the starting point, implementation takes
6 to
18 months. Banks with existing PSD 2 infrastructure can migrate faster. Insurers and asset managers without API experience need more time. The Council negotiating position provides phased deadlines of 24,
36 and
48 months after entry into force per data category.
What encryption standards apply to FIDA APIs?
For FIDA APIs, end-to-end encryption with TLS 1.3 for data in transit and AES‑256 for data at rest is the market standard; the binding specification comes from the respective scheme. Tokenization provides additional protection for sensitive financial data. Post-quantum cryptography will become relevant as FIDA requires long-term data security.
How are FIDA and DORA connected regarding API security?
FIDA and DORA complement each other: DORA defines operational resilience for ICT systems including APIs. FIDA builds on this framework and additionally requires API-specific security such as consent dashboards, third-party access controls and incident response plans. Banks should implement both regulations together.
