Fraudulent users cost you. Trueguard stops them. Trueguard is an automated fraud detection platform that blocks fake signups, bot registrations, and free tier abuse before they impact your revenue. It analyzes device fingerprints, IP and network intelligence, disposable email signals, geolocation, and real-time risk scores to catch bad actors the moment they appear, all without adding friction for legitimate users.

Trueguard Email Verification is a real-time email verification API. Send one address and get one JSON response with a clear status: safe, risky, invalid or unknown. Each request runs a live SMTP check against the mail server. It also checks syntax, MX records and domain age, and detects disposable, role-based and free-provider addresses. Advanced catch-all bypassing checks if a mailbox really exists on that accept all mail, so fewer addresses come back as risky. Use it on signup forms, checkout pages and CRM imports to stop bounces, fake accounts and free-trial abuse.
Trueguard protects your SaaS against Temporary Emails, Free Tier Abusers, Automated Bots, and Lost Revenue.
