Case Study: Calsonic Kansei China achieves faster Office 365 performance and major bandwidth and cost savings with Riverbed SteelHead

Calsonic Kansei China - Customer Case Study

Calsonic Kansei (China), a rapidly growing auto-parts manufacturer with over 4,000 employees across 14 sites, faced degraded end-user experience and soaring IT costs after adopting a cloud-first strategy. Bandwidth‑intensive SaaS apps—particularly Microsoft Office 365—consumed network capacity (email traffic alone reached as much as 90% of available bandwidth), slowing performance, harming productivity, and leaving IT with limited visibility and planning tools for future cloud rollouts.

The company deployed Riverbed SteelHead SaaS and SteelHead CX across its sites to optimize SaaS delivery and regain control of network traffic. Deployment completed quickly and delivered immediate benefits: email traffic was reduced by more than 50%, ERP and file‑sharing traffic by over 70%, email delivery became roughly 2x faster, costly network upgrades were avoided, and improved visibility and capacity‑planning tools set the stage for accelerated, cost‑controlled digital transformation.
