About Trueguard

Trueguard is a fraud detection platform for SaaS products that aims to stop fake signups, bot registrations and free-tier abuse. It combines device fingerprinting, IP intelligence, disposable email detection and real-time risk scoring to flag or block bad actors while letting legitimate users through.

Setup involves installing a JavaScript snippet on a website to collect unique visitor IDs, then integrating the Trueguard API into the backend to receive risk signals and scores. The browser ID is designed to persist through cookie clears, incognito sessions and VPN or proxy use. Signals include email intelligence, VPN and proxy detection, geolocation, multi-account detection per device and bot detection, and a rules engine lets teams automatically block or flag accounts. Live dashboards and alerts surface activity as it happens.

Trueguard positions itself for startups through enterprises. It also offers a standalone Email Verification API and free tools such as a VPN and proxy checker, an IP location checker, and a domain scan that shows whether a product's emails are landing in public disposable inboxes.
