Automated Free Trial Abuse Prevention for SaaS.
Stop multi-accounting, block disposable emails, and detect residential proxies. Protect your revenue without adding friction for real users.
How Trueguard Stops Multi-Accounting
Abusers use VPNs, proxies, and incognito windows to bypass basic checks. Our software correlates deep technical signals to identify the person behind the screen.
Device Fingerprinting
We generate persistent IDs based on hardware, browser, and TLS fingerprints (JA4). We detect when the same device creates multiple accounts, even if they clear cookies.
Residential Proxy Detection
Fraudsters use residential IPs to look like real users. We analyze IP velocity and reputation to block connections from known proxy networks and VPNs.
Disposable Email Checks
Instantly identify and block signups from temporary mail providers and domain spoofing attacks before they pollute your CRM.
The real cost of inaction.
- 10-60 hours/week: Support overhead
- 1-3 FTEs ongoing: Engineering time
- $25K-$200K/year: Lost conversion revenue
- $5K-$75K/month: Infrastructure overages
Stop free-tier abusers with Trueguard
Why free-tier abuse prevention is mission-critical for SaaS
Free-tier abuse is more than an annoyance - it's a hidden tax on growth. In our experience, unmitigated abuse can consume 10-25% of free-tier capacity and distort analytics, causing slower performance for real customers and masking true conversion signals.
Estimates shown are typical ranges based on aggregated customer data and industry benchmarks.
