Breach Data

Overview

Data breach intelligence allows security teams to understand credential exposure risk — which employees have leaked passwords, which services have been compromised, and what data types attackers may already possess. The primary source is HaveIBeenPwned (HIBP), which aggregates billions of compromised accounts from hundreds of breaches. Additional sources like DeHashed, IntelX, and LeakCheck provide deeper data for authorized investigations.

Requires: HIBP API key for account/domain lookups (free for personal use, paid for domain search).
