Free trial abuse is becoming increasingly sophisticated, with attackers using automated scripts to create fake accounts en masse and farm backend resources without contributing to revenue. The problem has evolved from simple tactics to industrialized attacks that bypass traditional defenses such as CAPTCHA, email verification, and IP-based rate limiting. The economics of modern SaaS have changed, with high-value inference operations embedded in the core user flow, making it more damaging. Traditional defenses are no longer effective, and attackers can now use open-source "abuse kits" to simulate clean browser environments and evade detection. To combat this, WorkOS Radar provides real-time behavioral analysis, detecting automation and identifying shared connections across accounts, while allowing for customization of defenses through its Actions system.
