About LeakCheck
What is LeakCheck?
LeakCheck is a data breach search engine that lets you instantly check if your emails, usernames, phones, domains, or passwords have been exposed in known data leaks. It searches across a database of over 10 billion leaked records and returns results in under 100 milliseconds — making it one of the fastest breach-checking tools available.
Who is it for?
LeakCheck is built for cybersecurity teams, online businesses, government regulators, and individuals who need to monitor and control exposure of corporate or personal data. It is not a casual identity monitoring service — it is a forensic-grade tool designed for ongoing leak surveillance, bulk data checking, and compliance with GDPR, CCPA/CPRA, and ISO/IEC standards.
Key use cases
Use LeakCheck to verify if employee credentials appear in info-stealer logs, run daily bulk checks on up to 500,000 lines, reverse-search a password to find which accounts are linked, or export detailed reports for incident response. The built-in Telegram bot mirrors your plan limits so security teams can run checks and receive alerts from any device.

- Detailed breach reports — Each report lists logins, passwords, names, DOB, phone, address, zip code, and info-stealer log origin URLs.
