SOOSAN INT and Keysight Help South Korean National Bank Modernize Its Network Monitoring and Threat Detection

Case Studies

A premier South Korean government-owned bank is modernizing its main data center security architecture to address expanding network traffic and an evolving threat landscape. Facing the critical need to eliminate blind spots within encrypted connections while ensuring seamless orchestration across their security stack, the organization sought a centralized visibility solution.

 

To achieve this, they deployed a powerful joint architecture combining Keysight network packet brokers with SOOSAN INT’s ePrism SSL VA. This integration replaced isolated monitoring with a unified platform, ensuring that high-speed traffic is decrypted, filtered, and precisely delivered to the right security tools without compromising performance or reliability.

 

The Challenge:

Securing a financial institution demands complete visibility and precise orchestration. To strengthen IT security, accelerate threat detection, and expand traffic visibility and monitoring as their network evolves, the bank decided to deploy a network visibility and distribution solution in its main data center.

They conducted a Proof of Concept (PoC) demonstration that led to a decision to establish a centralized visibility platform for security devices based on Keysight’s Vision NPBs. During this process, the Keysight team introduced ePrism SSL VA to the security team to ensure visibility into TLS/SSL traffic. The decision-making team consisting of system engineers, cybersecurity managers, and security architects required the new platform to provide:

 

  • Seamless integration with existing security solutions (IPS, APT, URL filtering, SIEM)
  • Secured network visibility and comprehensive visibility into TLS/SSL traffic
  • High-capacity processing of aggregated network traffic
  • A user-friendly, cost-effective solution with scalability to meet future requirements

 

After conducting benchmark tests (BMT) to compare vendor approaches, the bank selected ePrism SSL VA as its SSL visibility solution and moved forward with a joint SOOSAN INT/ Keysight deployment.
