Case Study: Trendyol achieves robust security and scalable performance with Cloudflare

Trendyol uses Cloudflare to boost its ecommerce platform's security and performance

Trendyol, Turkey’s largest and fastest‑growing mobile commerce company, serves over 15 million customers through a network of 2,000+ merchants. The business must balance high performance and rapid customer engagement with strong security—challenges that intensify during peak events like Black Friday when traffic and attack volumes spike.

To meet that need Trendyol deployed Cloudflare’s WAF, DDoS protection, rate limiting, DNSSEC, SSL/TLS, managed DNS and load balancing. During a proof‑of‑concept that included Black Friday the WAF blocked over 85 million malicious requests, and in April 2020 Cloudflare blocked more than 180 million, keeping the site scalable and performant while providing fast support and preserving customer engagement.
