The Problem

Stolen credentials from infostealer malware and data breaches are the #1 initial access vector for ransomware attacks, yet most companies only discover exposures months after the fact through expensive enterprise threat intelligence platforms.

The Solution

A lightweight, API-first credential monitoring service that ingests data from dark web sources, stealer log marketplaces, and breach databases, then matches against customer domains and delivers instant alerts with automated password reset and session revocation workflows.

Executive Summary

A developer-first API that continuously monitors dark web marketplaces, stealer logs, paste sites, and underground forums for exposed employee credentials, session tokens, and API keys. Delivers real-time webhook alerts and integrates with SIEM, SOAR, and identity platforms for automated response.
