Heretic is built for businesses getting wrecked by fraud and automation, where vague probability scores and broad tolerance for false positives do more harm than good. Our background probe instantly detects whether a visitor is attempting to mask their identity, giving you full control over how to respond. If you need definitive enforcement, our challenge widget provides an uncompromising fallback: it requires users to verify authenticity on a physical mobile device by analyzing the environment's physics and cryptographically signing the result with a WebAuthn passkey. Engineered from an offensive security perspective, Heretic focuses on what hurts sophisticated attackers most—flipping the economics of abuse directly back onto them. Start testing with our sandbox tier: 1,000 free probes every month.
