Case Study: Zendesk boosts performance and security for 125,000+ customer sites with Cloudflare

Zendesk - Customer Case Study

Zendesk, a leading customer service platform serving over 125,000 businesses worldwide, faced escalating security and performance challenges as it came under large-scale attacks that generated thousands to millions of malicious requests. Protecting customer data and keeping the platform reliable during traffic spikes became a top priority, and Zendesk needed a solution that could control incoming traffic and meet stringent security requirements.

By deploying Cloudflare’s integrated edge platform, Zendesk gained enterprise-grade DDoS mitigation, global traffic filtering, and performance acceleration that simplified its stack and improved reliability. The result was a faster, more resilient application that handles spikes with confidence, enhances customer experience, and delivers measurable performance gains (including a reported up to 6x improvement in targeted content delivery time).
