Claims that stolen credentials drive a large share of breaches and shows an operational pipeline that actually blocks them: ingest public combo lists and dark‑web stealer logs into blob storage, use Azure Databricks autoloader into delta tables, call internal admin APIs every 5–15 minutes to validate accounts, trigger force password reset + MFA and global session logout, and notify managers. Case wins include preventing reuse from Colonial‑style VPN leaks, stopping MFA‑fatigue paths like Uber, and reducing exposure from 25+ billion leaked credentials; vendor speed and transparency prove decisive.
