Case Study: Castlight Health achieves stronger security with less maintenance using Fastly Next-Gen WAF

Castlight Relies on Signal Sciences for Innovative Security Insights

Castlight Health sought to replace its legacy web application firewall to achieve better performance, security visibility, and attack coverage while avoiding maintenance hassles. Their traditional appliance-based WAF required sharing SSL keys, introduced network complexity, and failed to inspect all traffic, creating unnecessary risk.

Signal Sciences provided a next-gen WAF with a modern architecture that installed directly on their web servers. The solution recouped 10 hours of monthly maintenance, cut report preparation time in half, and detected 50% more attacks. Castlight Health also benefited from features like Power Rules and the Network Learning Exchange (NLX) to proactively block threats, all while maintaining HIPAA compliance.
