AI BriefingKakaoPay Securities' Adoption Case of Cilium Egress Gateway
Key point
KakaoPay Securities adopted **Cilium Egress Gateway** to secure network management efficiency and security visibility.
Details
KakaoPay Securities introduced Cilium into its Kubernetes environment to solve the scalability and operational efficiency issues of its existing physical server-based gateway.
Cilium is a CNI based on eBPF technology that overcomes the limitations of the existing kube-proxy and provides powerful security policies and network visibility without any application code modification. In particular, through Hubble, it enables effective detection of anomalies by monitoring real-time network communication status and metrics.
Cilium Egress Gateway allows setting an egress NAT policy that assigns a consistent IP to outbound traffic from service Pods. This provides the following benefits.
- Easy application and management of customized policies for specific services
- Increased efficiency in external firewall management through consistent IP usage
- Secured communication convenience in external institution integration and hybrid cloud environments
