Product Overview

What is Metlo?

Metlo is an open-source platform designed to secure APIs by automatically discovering all API endpoints, scanning for sensitive data, and detecting vulnerabilities and attacks in real time. The platform enables organizations to inventory their API landscape, assign risk scores to endpoints, and proactively test for security issues before deployment. Metlo provides flexible deployment options, including a managed cloud service, self-hosted solution, and a fully open-source version, making it suitable for businesses of all sizes. Its agentless setup allows for quick integration without code changes, and it offers end-to-end encryption to protect captured data.


Key Features

  • Comprehensive Endpoint Discovery

    Automatically scans network traffic to inventory all API endpoints, including legacy, undocumented, and shadow endpoints.

  • Sensitive Data Scanning & Risk Scoring

    Identifies endpoints handling personally identifiable information (PII), assigns risk scores, and highlights high-risk areas.

  • Real-Time Attack Detection & Blocking

    Monitors API traffic for malicious behavior, detects attacks such as SQL injection and XSS, and blocks bad actors in real time.

  • Customizable Security Testing

    Allows users to build and run automated security tests, including tests for OWASP Top 10 vulnerabilities, directly within the platform.

  • CI/CD Pipeline Integration

    Integrates with CI/CD workflows to identify and remediate security issues during development and staging.

  • End-to-End Data Encryption

    Encrypts all captured API traffic using public-private key encryption, ensuring sensitive information is protected.


Use Cases

  • API Inventory Management : Gain visibility into all API endpoints, including undocumented or legacy APIs, to maintain a comprehensive security posture.
  • Sensitive Data Protection : Identify and monitor endpoints handling PII or financial data to prioritize security measures and compliance.
  • Proactive Vulnerability Testing : Run automated and custom security tests to detect and fix vulnerabilities before APIs are exposed to production.
  • Real-Time Threat Detection : Monitor API traffic to detect and block malicious requests, reducing the risk of successful attacks.
  • Regulatory Compliance Support : Assist in meeting compliance requirements by providing detailed audit trails and risk assessments of API endpoints.
