Trial abuse is one of the most underreported forms of SaaS fraud. It doesn't show up as a chargeback. It shows up as zero revenue from a churning customer base.
This client — a B2B analytics platform with pricing starting at $499/month — noticed their trial-to-paid conversion rate had collapsed from 28% to 11% over six months. The culprit: a competitor (and eventually a loose network of resellers) was spinning up thousands of proxy-masked trial accounts to scrape feature capabilities and pricing logic.
The Integration
The platform integrated Sentinel's Edge SDK on their signup form in a single afternoon. No redesign. No user-visible friction. The SDK invisibly evaluated each new registration against 400+ behavioral and hardware signals before the account was provisioned.
Results After 30 Days
Trial account creation from anonymous proxy networks dropped by 97%. Crucially, legitimate trial signups were completely unaffected — no real users saw friction or were blocked. With trial abuse eliminated, the platform's true conversion rate recovered to 26%. The CFO calculated the annualized revenue impact at $2.1M.
Key Takeaway
Proxy-based trial abuse is invisible to IP reputation tools because residential IPs look legitimate. Sentinel defeats it by analyzing behavioral telemetry — timing signatures, hardware entropy, network stack anomalies — that no proxy network can fake.
