WorkOS logo What Is Free Trial Abuse—And How Can You Stop It?
Free trials are meant to drive adoption—not rack up costs. But for AI apps, trial abuse is a growing threat: fake signups, disposable emails, and automated account farming are draining compute and distorting metrics.

WorkOS Radar helps stop abuse before it spreads. With built-in protection against bots, free trial abuse, brute force attacks, and even impossible travel logins, Radar gives your app the real-time defense it needs.

Protect your app today with WorkOS Radar.
