we handled a 40K IP DDoS
attack on a tight budget
When a partner’s platform went down under a massive DDoS attack, our infrastructure team moved fast to restore stability without expensive enterprise tooling. Facing over 205 million requests from 40,000+ unique IPs, we analyzed AWS traffic patterns, investigated ALB logs, and identified attack vectors targeting a specific endpoint.
Working within a tight infrastructure budget, we combined AWS WAF, geo-blocking, SSR traffic whitelisting, and custom log analysis scripts to isolate malicious traffic and maintain service availability. By identifying 159 attacking subnetworks and applying targeted firewall rules, we successfully mitigated the attack while keeping infrastructure costs under control.
This case highlights our expertise in cloud infrastructure engineering, AWS security, DDoS mitigation, scalable backend systems, and cost-efficient DevOps architecture — proving that resilient infrastructure is not only about enterprise budgets, but also about smart engineering and rapid incident response.
