Case Study: SMBC Nikko Securities achieves 24x7 ICT resilience and strengthened cybersecurity with NTT Communications

SMBC Nikko Securities - Customer Case Study

SMBC Nikko Securities (Hong Kong) Limited, a wholly owned subsidiary of SMBC Nikko Securities Inc., needed to strengthen IT governance, ensure data resilience and defend against increasingly sophisticated cyberattacks while freeing its internal IT team to focus on strategic work. The firm sought 24x7 infrastructure and security monitoring, rapid incident response, and reliable regional connectivity to maintain client trust and meet regulatory expectations.

NTT Communications and NTT Security delivered an end-to-end managed ICT and security solution: Tier‑III+ data center hosting with high‑speed links to regional sites, 24x7 managed services and service desk, and NTT Security SOC–backed threat detection and response. The result was improved operational efficiency, resilient and fast connectivity across data centers and offices, proactive intrusion prevention and faster recovery from incidents — allowing SMBC Nikko to maintain service excellence and focus on business expansion.
