Audit website security and send AI reports via Claude, Gmail, Slack and WhatsApp

Description

Who it's for
This advanced n8n workflow is designed for web developers, system administrators, security analysts, and agency owners who need to automate the monitoring of website security posture. It acts as a virtual security auditor, automatically scanning webpages for security misconfigurations, analyzing headers, and identifying potential client-side vulnerabilities using advanced AI.

Features
Multi-Source Triggering**: Supports three different input methods—Manual execution, scheduled scans from Google Sheets, or on-demand checks via a Form Trigger.
Deep Security Analysis**: Uses LangChain Agents (powered by Anthropic/Claude) to audit both HTTP headers (Config Audit) and HTML content (Vulnerability Audit) for security flaws.
Smart Grading System**: Automatically calculates a security grade (A+ to F) based on the presence and configuration of critical security headers like CSP, HSTS, and X-Frame-Options.
AI-Generated Reporting**: Creates a detailed, professional HTML report highlighting critical vulnerabilities, information leakage, and configuration warnings with specific fix recommendations.
Automated Notifications**: Sends the final security report via Gmail (as an attached file), Slack, and WhatsApp simultaneously.
Sheet Integration**: When triggered by a schedule, it reads URLs from a Google Sheet and updates the sheet with the audit status upon completion.

Requirements
Anthropic API**: A valid API key (configured in the "Anthropic Chat Model" node) is required for the LangChain Agents to analyze security data and generate insights.
Gmail & Google Sheets**: Google OAuth2 credentials are needed to send the audit report via email and manage the list of websites to be audited.
Slack API**: OAuth2 credentials are required to send security status notifications to a Slack channel.
Rapiwa (WhatsApp)**: API credentials to send the audit summary via WhatsApp messages.

Important Notes
Manual Input**: If using the "Clicking Trigger" or "Form Trigger", ensure the URL is provided in the Landing Page Url field.
Sheet Setup**: For scheduled scans, ensure your Google Sheet contains columns for Links, Check, and SL.
Cost Management**: Using advanced AI models (like Claude) for extensive HTML and Header analysis can consume significant tokens depending on the size of the webpage.
Safety First**: This tool performs client-side analysis. For a complete penetration test, always engage a professional security professional.
