Case Study: Fizen achieves multi-country Open Banking scale with Binar's PSD2-grade AISP/PISP platform

Fizen launches a multi-country Open Banking platform across 50+ banks with Binar

The customer, Fizen, faced the challenge of building a single Open Banking platform that could operate reliably across multiple EU and CEE markets. Despite fragmented bank APIs that differed in each country, they needed to meet stringent PSD2-grade security and enterprise SLA requirements for their partners. The vendor, Binar, provided its expertise to develop this multi-country AISP/PISP platform.

Binar implemented a modular Open Banking stack designed for scale, featuring a bank abstraction layer, a security-by-design architecture, a data orchestration engine, and a compliance operations layer. This solution provided Fizen with a single integration point to access over 50 banks across 7 markets. The results were a production-ready platform handling over 10,000 account information requests and 1,000 payment transactions daily with enterprise-grade reliability and full PSD2 compliance.
