Website Security Scanner

This workflow provides an automated website security detection solution. Users only need to submit the homepage URL of the target website, and the system will scrape the webpage content and HTTP response headers, utilizing advanced AI models for in-depth security analysis. It can identify security configuration issues and potential vulnerabilities, generating a detailed HTML format security report, which is then sent via email to designated recipients. This process eliminates the tediousness of manual checks, significantly enhancing the efficiency and accuracy of security audits, and helping users promptly understand and address website security risks.

Workflow Name

Website Security Scanner

Key Features and Highlights

This workflow automatically fetches webpage content and HTTP response headers based on the user-submitted homepage URL. Leveraging the OpenAI GPT-4o-mini model for in-depth security analysis, it identifies website security configuration issues and potential client-side vulnerabilities. It then generates a professional, intuitive HTML-formatted security report and sends it via Gmail to a specified email address. The report includes a security rating score, detailed key vulnerabilities, configuration recommendations, and risk warnings, helping users gain a comprehensive understanding of their website’s security posture.

Core Problems Addressed

  • Automated detection of missing or misconfigured HTTP security headers to prevent security gaps
  • Identification of sensitive information leaks in webpage source code and common client-side vulnerabilities (e.g., XSS, CSRF risks)
  • Provision of targeted remediation advice to reduce the likelihood of website attacks
  • Elimination of tedious manual inspections, improving security audit efficiency
  • Timely delivery of security reports to relevant personnel for rapid response and remediation

Application Scenarios

  • Security self-assessment before website launch by development teams
  • Regular website security monitoring by security operations personnel
  • Quick security risk evaluation for small and medium-sized enterprises and individual site owners
  • Automated security assessment support for security consultants serving clients
  • Demonstration tool for automated security detection in educational and training settings

Main Workflow Steps

  1. The user accesses and fills out a web security scan form containing the “Landing Page URL” field, submitting the target website’s homepage URL.
  2. The workflow uses an HTTP request node to fetch the target webpage’s HTML code and HTTP response header information.
  3. The OpenAI GPT-4o-mini model concurrently executes two security analysis tasks:
    • Security Configuration Audit: Analyzes HTTP headers and cookie settings, checking the completeness and correctness of security headers.
    • Security Vulnerabilities Audit: Reviews webpage source code and visible content to identify client-side security vulnerabilities and sensitive information leaks.
  4. The two analysis results are merged and summarized, calculating a security rating score and tallying key vulnerabilities and warnings.
  5. A code node formats the audit results into an aesthetically pleasing HTML security report, highlighting the security score, vulnerability details, and configuration recommendations.
  6. The Gmail node sends the security report via email to the preconfigured recipient address.
