LoginLlama

LoginLlama is a security API that scores each login attempt from 0 to 10 to detect account takeover, credential stuffing, and bot traffic. It solves the problem of stolen passwords being used by attackers by providing a risk score before the login is finalized. The product is aimed at developers and engineering teams in B2B companies of all sizes, from startups to enterprises, who want to add an extra layer of security without building an ML team. It is delivered as a simple API call that integrates with existing auth systems, with SDKs for popular frameworks, and it fails open by design to avoid blocking legitimate users.
