Managing outbound traffic to SBM services through an API Gateway to improve security, observability, and rate limit control
In the insurance sector, integrations with the Insurance Information Center (SBM) are critical for core business processes. In the customer environment, multiple applications were directly calling SBM services, resulting in an unmonitored and hard-to-control outbound traffic pattern. Additionally, SBM-enforced rate limits and credential management required a more centralized and secure approach.
A dedicated API Gateway was deployed in the DMZ to centrally manage all outbound traffic to SBM services. The gateway securely retrieved credentials from CyberArk, handled token management, reduced duplicate requests through response caching, and enforced SBM rate limits at the gateway level. This approach enabled a secure, observable, and controlled outbound integration architecture.
Insurance companies rely heavily on SBM services for processes such as vehicle registration and policy validation. When multiple applications access SBM services directly over the internet, security, observability, and cost control become increasingly difficult.
In this project, the customer lacked a centralized outbound integration layer for SBM traffic, leading to limited visibility and operational risks.
The existing SBM integration model introduced several challenges:
To address these challenges, a centralized outbound API governance model was implemented:
With this solution, the customer transformed SBM integrations from an uncontrolled outbound traffic pattern into a secure and centrally managed architecture. Rate limits were proactively controlled, credentials were securely managed, duplicate requests were minimized, and full operational visibility into SBM traffic was achieved.
SBM integrations are critical for our business continuity. By managing all outbound traffic through the API Gateway, we significantly improved security, gained control over rate limits, and reduced unnecessary costs. We now have full visibility into our SBM traffic.
