Case Study: Remitly achieves PCI compliance and stronger app protection with Fastly Next-Gen WAF

Defending Remitly with Signal Sciences

Remitly, a digital remittance company, needed a web application firewall (WAF) to meet PCI compliance and protect sensitive customer transactions without impacting performance. Their challenge was distinguishing between legitimate traffic and malicious attacks, especially from concentrated IP ranges, as blocking valid users would frustrate their global customer base. They chose the Fastly Next-Gen WAF from Signal Sciences to address this.

The solution from Signal Sciences provided the visibility to allow good traffic while blocking malicious requests from the same network, eliminating false positives. This was crucial for accurately handling irregular traffic patterns from legitimate users. The implementation allowed Remitly to achieve its compliance goals and protect its entire application with easy-to-manage rules, saving significant analyst time compared to traditional WAFs that require extensive tuning.
