The challenge
Duolingo's 113 million monthly active learners rely on the app's availability, but frequent DDoS attacks consumed engineering hours - a single attack could spawn multiple issues - and threatened the customer experience.
The solution
Duolingo adopted Fastly's Next-Gen WAF and Response Security Service, backed by Fastly's security operations team, to build platform resilience and simplify security.
“The first time we blocked a DDoS attack—39 million requests in five seconds—and no one noticed, at that moment I felt the organization accepting the trust.”
MBMatt BrandmanSenior Engineering Manager, Platform Security, Duolingo
The results, in context
Fastly made a real dent in Duolingo's DDoS attacks in less than a week. In one instance the team blocked a DDoS attack of 39 million requests in five seconds with no user-visible impact.
