Vulnerability Scan Service

Vulnerability Scan Service (VSS) detects the vulnerabilities in the servers and websites. It provides services such as common vulnerability scan, vulnerability lifecycle management, and scan customization. After you create a scan job, you can manually start it to detect the vulnerabilities in the website and obtain recommended actions.


VSS quickly detects the vulnerabilities in your website and host, generates detailed assessment reports, and provides recommendations for fixing different types of vulnerabilities.

  • Preliminary Scan

    New users can experience a preliminary scan without verifying your domain ownership to estimate website risks.

  • Host Vulnerability Scan
    • In-depth scanning

      Performs multi-dimensional OS vulnerability detection and configuration checking.

    • Intranet scanning

      Enterprises can choose to enact an intranet scanning policy on servers.

    • Weak password scan
      • Multi-scenario applicability

        Scans for standard web services, all OSs, and 90% of all middleware, including databases.

      • Built-in weak password library

    • Middleware scan
      • Diverse scenarios

        Supports vulnerability scanning of mainstream web containers, foreground development frameworks, and background microservice stacks, as well as configuration compliance scanning.
