Billions of leaked records.
One search tells you if you're in them.
Leak Data Search scans multiple independent breach databases in a single pass — including the global compromised-password corpus and a constellation of credential-leak feeds — and returns one unified verdict. Search by email, username, password, domain, or phone.
The Leak Data Search engine fans your query out across every connected breach database in parallel, then returns a single aggregated verdict — no per-source attribution, no noise.
Complete control of your personal data
Independent breach intelligence — built for individuals, security teams, and businesses that need to know exactly where their data has surfaced.
Instant checking
Search across billions of leaked records by email, username, phone, password, or domain. A response arrives in well under 100 ms.
Real-time monitoring
Receive notifications about new entries for critical personal and corporate data — corporate emails, your own emails, user logins, and passwords.
Confidential by design
Passwords are hashed with SHA-1 and queried via the k-anonymity model. The raw secret never leaves the server. Every check is anonymous.
Aggregated verdict
All results are merged, deduplicated, and sorted into a single exposure list — no per-source attribution, just the facts you need.
Reversible search
Reverse the direction of a search — start from a password or domain and instantly see every account and record associated with it.
Compliance-ready
Aligned with GDPR, CCPA/CPRA, and ISO/IEC standards — built for cybersecurity teams and online businesses that need defensibility.
What data is displayed in the check report?
Each report lists the exact fields found for your query — logins, passwords, names, contact and location details, and records pulled straight from info-stealer logs.
Account credentials
The logins tied to a breached account — and the passwords stored with them.
Personal identity
The person behind the account: their names and date of birth.
Contact & location
How to reach the person and where they are — phone, address and postal code.
Info-stealer logs
Credentials captured directly by info-stealer malware, with the websites they were entered on.
