Securing Global Payment Connectivity with Mutual TLS
ART built a mutual TLS ingress architecture for a global fintech, cutting client onboarding time by 50% and removing its dependence on client-managed infrastructure.
The opportunity
A global fintech connects its clients to its payment platform. Onboarding each one depended heavily on infrastructure the client managed, which caused delays, limited how far the process could scale and added operational risk.
Connections into production also lacked mutual TLS authentication and layered security controls, leaving the platform more exposed to security threats than a payment business can accept.
The transformation
ART designed a layered, security-first architecture that brings security, observability and automation into the ingress layer, so clients can connect without changing their own infrastructure.
- 01
Mutual TLS at the Ingress Layer
ART enforced mutual TLS at the ingress layer using NGINX reverse proxies, so the platform and each client authenticate one another before any traffic reaches production.
- 02
Layered DDoS and Firewall Protection
ART added layered DDoS and firewall protections in front of the platform, giving the ingress defence in depth.
- 03
Automated Certificates and CI/CD
ART automated certificate provisioning and built CI/CD pipelines for the ingress stack, removing the manual steps that slowed onboarding and caused errors.
- 04
Centralised Observability and Scalable Infrastructure
ART centralised monitoring with OpenTelemetry for end-to-end visibility, and ran the ingress on horizontally scalable cloud infrastructure that grows without client-side changes.
