# Trueguard

Trueguard is a fraud detection platform that helps SaaS companies stop fake signups, bot registrations, free tier abuse, and fraudulent users before they cause damage. It analyzes multiple risk signals at the point of signup and verification, including device fingerprinting, IP intelligence, disposable email detection, and real-time risk scoring, to identify and block bad actors without adding friction for legitimate users. Trueguard has processed over 70 million verification events.

## What Trueguard Does

- Detects and blocks fake account registrations, bot signups, and synthetic identities
- Identifies disposable and temporary email addresses used for free tier abuse
