Case Study: Upyun protects clients from attacks and boosts performance by 30% with Cloudflare

Upyun protects clients from attacks and improves customer satisfaction and retention with Cloudflare

Upyun, a Hangzhou‑based provider of customizable CDN and cloud services (cloud storage, processing, security, AI video cloud and more) serving clients such as Starbucks and Bytedance, helps companies accelerate content distribution and product development. As Upyun expanded globally it faced rising security and performance risks and needed to handle surges in local and international traffic during peak events like Singles’ Day without compromising speed or reliability.

Upyun partnered with Cloudflare, deploying Cloudflare WAF and Spectrum alongside Cloudflare’s global network to mitigate attacks and protect TCP/UDP applications. The integrated solution reduced manual attack intervention, improved peak‑time website speeds by up to 30%, and increased customer satisfaction and retention, allowing clients to focus on scaling their businesses.
