Case Study: DeNA achieves centralized visibility and lower operational costs with Fastly

Centralizing Visibility While Reducing Operational Cost

DeNA, a Japanese corporation focused on digital portals, mobile games, and e-commerce, needed a more scalable web security solution as its legacy hardware WAF drove high operating costs, slow response times, and poor handling during traffic spikes. The outdated system made it difficult for the team to respond quickly, reroute requests, or scale security efficiently.

Fastly implemented its Next-Gen WAF across five of DeNA’s properties, giving the company centralized visibility, faster performance, and easier deployment. With Fastly, DeNA reduced operational and capital expenses, improved attack detection using richer web request context, and gained deeper visibility across teams, including previously unseen traffic such as Tor activity.
