Case Study: Dcard achieves 2–3× faster international response times and robust DDoS protection with Cloudflare

Cloudflare solutions amplify speed and protect Dcard’s global community platform against attacks

Dcard, Taiwan’s largest next‑generation social platform with 6 million members and 18 million monthly visitors, expanded beyond college users into e‑commerce and new markets like Hong Kong and Japan. The company needed to protect anonymized user data and stop sophisticated attacks while improving overseas performance and reducing the complexity of in‑house development—its Taiwan‑based servers caused slow response times in Japan and Hong Kong.

Dcard adopted Cloudflare’s WAF, DDoS protection, Rate Limiting, global edge CDN and Cloudflare Workers to filter malicious traffic, accelerate static and dynamic content, and simplify development. The result: automated attack detection and blocking, 2–3× faster response times in international markets, about a 10% reduction in bandwidth use (lowering costs), and a more flexible, manageable development and security stack.
