CJS CD-Keys - Customer Case Study

CJS CD-Keys, a leading distributor of PC game keys that sells millions of digital downloads yearly, was suffering frequent, large DDoS attacks (peaks ~700,000 packets/sec) that repeatedly knocked their eCommerce site offline and eroded revenue.

By moving to Cloudflare’s Business Plan for advanced DDoS mitigation and caching, CJS stayed online within an hour despite heavy attacks, cut server requests by about 75% (nearly half a billion), saved >23 TB of bandwidth (≈93%), achieved a 10x improvement in page load time and 92.2% better server connection time, and saw sales rise 318% (monthly downloads from 2,838 to 11,879), enabling the company to scale to a multimillion-dollar business.
