Case Study: finleap connect achieves secure mTLS at scale with Buoyant Linkerd

Operating high-density bare-metal clusters in the highly regulated financial industry

finleap connect, the leading independent Open Banking platform provider in Europe, needed to secure highly sensitive financial data across high-density bare-metal Kubernetes clusters while meeting strict EU regulatory requirements. Facing a five-month deadline tied to PSD2 compliance and a difficult legacy platform migration, the team needed to implement mTLS across all services without slowing developer productivity.

Buoyant’s Linkerd service mesh was selected for its simplicity and low operational overhead. Buoyant helped finleap connect roll out Linkerd in under an hour and reach production in about a week, enabling mTLS across all services, automated certificate rotation, and improved observability with golden metrics. The company also adopted canary deployments with Linkerd and Flagger, reducing TLS complexity and helping them meet their deadline with minimal impact on the engineering team.
