extensionCommon Features
extensionEmail and Account Breach Lookup
APIs like Have I Been Pwned let consumers and security teams check whether an email address, username, or phone number has appeared in known data breaches and stealer log corpora.
extensionPwned Password Checking (K-Anonymity)
The Pwned Passwords API exposes 800+ million breached password hashes through a k-anonymity protocol, letting applications block known-compromised credentials without transmitting full hashes.
extensionDark Web and Underground Forum Monitoring
Enterprise breach intelligence platforms continuously scrape dark-web marketplaces, ransomware leak sites, Telegram channels, and underground forums for mentions of customer data, executives, brands, and credentials.
extensionStealer Log and Credential Exposure Feeds
Modern breach intelligence increasingly centers on infostealer malware logs (RedLine, Raccoon, Vidar, LummaC2) that capture browser-stored credentials, session cookies, and crypto wallets at scale.
extensionRansomware Leak-Site Tracking
Threat intelligence APIs track ransomware group leak sites (LockBit, Cl0p, ALPHV, Akira) to surface newly disclosed victim organizations and stolen data postings as they appear.
extensionVulnerability and Exposure Feeds
Authoritative vulnerability databases (NVD, CISA KEV) and commercial exposure platforms (Qualys, Rapid7, Tanium) expose CVE, CVSS, and known-exploited-vulnerability metadata via API.
extensionRegulatory Breach Notification Feeds
Government authorities (FTC, state AGs, EU DPAs, HHS) publish disclosed breach filings; security teams ingest these feeds to track third-party and supply-chain breach exposure.
extensionCredential Stuffing Defense
Identity providers (Okta, Auth0) and password managers (1Password, Bitwarden, LastPass) integrate with breach feeds to block re-use of known-compromised passwords and force resets on exposed accounts.
task_altUse Cases
task_altEmployee Credential Exposure Monitoring
Security teams continuously query breach intelligence APIs for corporate email domains to detect employee credentials exposed in third-party breaches and infostealer logs, triggering forced password resets.
task_altCustomer Account Takeover Prevention
Consumer applications integrate Pwned Passwords and breach lookup APIs at signup and login to block known-compromised credentials and notify customers of exposure.
task_altExecutive and VIP Protection
Brand and executive protection teams use dark-web monitoring APIs to detect doxxing, leaked personal data, and impersonation targeting C-suite, board members, and high-value employees.
task_altThird-Party and Supply-Chain Risk
GRC teams ingest breach-notification feeds and regulatory disclosures via API to track breach incidents at vendors, suppliers, and partners that handle their data.
task_altRansomware Victim Intelligence
Threat intel teams subscribe to ransomware leak-site feeds via API to alert on newly named victims relevant to their industry, supply chain, or geography.
task_altVulnerability Prioritization
Vulnerability management teams combine NVD CVE data, CISA's Known Exploited Vulnerabilities (KEV) catalog, and commercial exposure platforms to prioritize patching based on breach exploitation evidence.
task_altRegulatory Breach Disclosure Compliance
Privacy and legal teams query FTC, state AG, and EU DPA breach-notification APIs to track required disclosures and benchmark their own incident response.
task_altAI Agent Breach Triage
AI agents wired to breach intelligence APIs autonomously enrich security alerts with exposure context, correlate stolen credentials with active sessions, and draft incident-response runbooks.
integration_instructionsIntegrations
integration_instructionsHave I Been Pwned
The canonical consumer breach-lookup service with 13+ billion breached accounts and 800+ million pwned passwords accessible via free and paid API tiers.

Authoritative catalog of CVEs with evidence of active exploitation, published by the US Cybersecurity and Infrastructure Security Agency as a machine-readable feed.
integration_instructionsNVD CVE API
The National Vulnerability Database REST API exposing CVE records, CVSS scores, CPE mappings, and CWE classifications used as the foundation of breach root-cause analysis.
integration_instructionsOkta and Auth0
Identity platforms that integrate breach-password feeds to block known-compromised credentials and trigger step-up authentication on suspected account takeover.
integration_instructions1Password Watchtower
Consumer and enterprise password manager that surfaces breach exposure for stored credentials via integration with Have I Been Pwned and proprietary feeds.
