Case Study: Sumitomo Corporation achieves secure global remote access and boosted productivity with Pulse Secure

Steadily Building a Foundation for Secure Access on its 100th Anniversary

Sumitomo Corporation, a global trading company with about 70,000 employees across 65 countries, prepared for its 100th anniversary and a headquarters relocation by overhauling its IT to support work reform and stronger group-wide collaboration. The IT team needed a secure, encrypted way to share information and prevent data leaks from devices taken offsite while enabling employees to work flexibly from anywhere.

Sumitomo deployed Pulse Secure’s PSA Series SSL‑VPN with unified clients installed in Tokyo, New York and London, giving employees simple, password‑tied connectivity. The solution delivered secure remote access and 24/7 encrypted communication, with 3,000–4,000 registered users (300–500 concurrent), improved productivity and an extensible foundation for future cloud authentication and group-wide collaboration.
