Web3 Security Threat Intelligence Tools

FYEO provides two complementary threat intelligence tools that strengthen security ecosystems against emerging cyber threats: the FYEO Dark API for credential exposure monitoring and the Third-Party Library Scanner for dependency vulnerability detection.

FYEO Dark API - Leaked Credentials Database

FYEO Dark API provides organizations with fast, easy access to the world's most comprehensive leaked credentials database for proactive threat monitoring and cyber risk mitigation. This third-party API integration offers real-time threat intelligence.

Comprehensive Database

The active database contains 29+ billion email addresses, 25+ billion total passwords, 500+ million phone numbers, and tracks 22,000+ data breaches, continuously updated with the latest breach data.

API Query Capabilities

Email Address Queries: Search by email to retrieve comprehensive exposure information including all associated leaked credentials and breach history.

Domain Queries: Query entire domains to identify all email addresses from your organization that appear in breach databases.

Telephone Number Queries: Search by phone number to identify associated accounts and credential exposures.

FYEO Risk Score

The FYEO score functions as a cybersecurity trust score where users with low exposure to leaked information score higher than users with many leaked passwords or easily guessed passwords. Use the score to evaluate security posture and enable risk-based authentication.

Third-Party Library Scanner - Dependency Security

FYEO's Third-Party Library Scanner provides complete visibility into third-party code dependencies, tracing real call paths from application code into external libraries to identify security risks before they ship.

Advanced Dependency Analysis

The scanner traces every path from your code into external libraries, down to the function level, answering critical questions: Which external functions does your code actually call? Which dependency paths introduce real security risk? Which libraries are abandoned or unmaintained? What breaks if a dependency is compromised?

Complete Path Mapping

The scanner maps how applications reach into third-party code at the function level, catches hidden vulnerabilities in transitive dependencies, identifies abandoned packages, and uses AI-powered security analysis with multi-pass review to reduce false positives.

What You Receive

Dependency Health Dashboard: Instantly spot which packages are actively maintained, behind on updates, abandoned or high-risk, or flagged with security advisories.

Security Audit Reports: Clear, prioritized results ranked by severity with the context needed to act quickly, focused on actual usage and real risk.

Complete Dependency Map: Visual view of how code connects to third-party libraries, showing actual call paths and dependency chains.

Multi-Platform Support

Built for modern development teams, the scanner works with Rust, Python, TypeScript/JavaScript, and Solidity (smart contracts). It fits seamlessly into existing workflows, can run locally or in CI/CD pipelines, exports reports in multiple formats, and enables sharing results across teams.

Integrated Threat Protection

Together, these tools provide comprehensive threat intelligence: FYEO Dark API monitors credential exposure and user account security risks, while the Third-Party Library Scanner identifies supply chain vulnerabilities and dependency security issues. Both integrate seamlessly into existing security infrastructure for proactive threat detection and risk mitigation.
