Case Study: Raiffeisen Bank International achieves faster API integration and stronger security with Kong Gateway Enterprise

Raiffeisen Bank International (RBI) achieves business-wide integration with Kong Gateway Enterprise

Raiffeisen Bank International (RBI) needed to replace a legacy API management platform that couldn’t keep up with the bank’s growing technical and regulatory demands. With a sprawling, heterogeneous “spaghetti” architecture across countries and legacy systems, RBI needed a way to standardize, reuse, and govern APIs while supporting a new real-time, plug-and-play business model. Kong Gateway Enterprise was selected to help enable this transformation.

With Kong Gateway Enterprise, RBI implemented a standardized API architecture across product, country, and group levels, using features like OpenID Connect for secure authentication and plugins for rate limiting and governance. Kong helped RBI expand to **437 standard APIs across 20+ domains**, with **35%** reused across multiple products, cut one lending rollout from **one year to three months**, and achieve **100% uptime** in the first year. Overall, Kong accelerated time to market by **200%** and strengthened RBI’s security posture.
