Estoy terminando un SaaS de seguridad y necesito que me entregues un módulo de escaneo de dominios/webs totalmente funcional. El objetivo es detectar: • Puertos abiertos que puedan exponer servicios sensibles • Vulnerabilidades de Cross-Site Scripting (XSS) • Evidencia de filtración de datos en la dark web originada por infostealers, consultando exclusivamente las APIs de DeHashed, LeakCheck o algún otro servicio mejor recomendado (acepto sugerencias). • MVP Online para Testear: [login to view URL] • Adjunto modelo de informe como plantilla para rellenar y agregar los hallazgos de puertos abiertos, vulnerabilidades, etc. (Descargar tambien el informe del MVP online, para usar como referencia y unificar los datos que deben ir en la plantilla) Flujo esperado 1. El usuario introduce un dominio o subdominio. 2. El módulo ejecuta el escaneo, consolida los hallazgos y verifica en DeHashed + LeakCheck si existen credenciales o datos comprometidos. 3. Genera un reporte en PDF y/o HTML con: – Resumen ejecutivo para directivos – Detalles técnicos (puertos, payloads XSS, respuestas del servidor, resultados de las consultas a cada API) – Recomendaciones de seguridad accionables Requisitos técnicos mínimos • Código claro y documentado, preferiblemente en Python o Node.js (acepto sugerencias). • Estructura preparada para integrarse en una arquitectura SaaS (microservicio o módulo acoplable con API REST). • Manejo adecuado de límites de rate-limit de DeHashed y/o LeakCheck (acepto sugerencias). • Registro de logs y tratamiento de errores. • Prueba de concepto ejecutada sobre un dominio de ejemplo con evidencia de resultados. Entrega 1. Repositorio con el código y archivo README de instalación. 2. Script o colección de Postman para probar la API. 3. Reporte generado a partir de la prueba de concepto. Valoraré que el módulo sea fácilmente extensible a otros tipos de vulnerabilidades (por ejemplo, SQL Injection o web shells) en futuras fases, pero por ahora céntrate en los puntos listados arriba.

Hi, We can develop this web-security scanning module as a modular SaaS component, with the architecture designed for future security checks. Our approach: * Review the existing MVP, report template, API requirements, and authorized scanning workflow. * Build a Python or Node.js REST service with a clean, extensible architecture. * Implement domain/subdomain validation and controlled security checks for exposed services and XSS indicators. * Integrate the selected breach-intelligence API after validating credentials, terms, response structure, and rate limits. * Normalize findings from different sources into a consistent internal format. * Add structured logging, error handling, timeouts, retries, and rate-limit controls. * Generate executive and technical reports in HTML/PDF following your supplied template. * Include evidence, affected endpoints, technical findings, API results, and actionable remediation guidance. * Keep scanning components modular so additional authorized security checks can be added later. * Provide a REST API plus Postman collection for testing. * Run a controlled proof of concept on an authorized example domain and document the results. * Deliver the repository, README, configuration instructions, and generated report. We’ll prioritize reliability, clear documentation, and safe, authorized testing throughout the implementation.

Hi, I'm Denis, a full-stack developer specializing in security and SaaS modules. I understand your project—building a web scanning module that detects open ports, XSS vulnerabilities, and cross-references compromised credentials against leak databases. The core challenge is orchestrating multiple security checks into a reliable, reportable workflow that fits your SaaS architecture. You need consistent data collection, proper API rate-limit handling, and reports for both technical and executive audiences. I've built similar systems where multiple external APIs required coordination, with robust error handling and logging for mid-scan failures. My approach: 1. Understand your current SaaS infrastructure and report template structure 2. Build the scanning engine in Python or Node.js with clear separation between port scanner, XSS payload executor, and leak database querying—each independently testable 3. Implement intelligent rate-limit handling with queue management to prevent API walls on repeated scans 4. Create a report generator that maps findings into your template, keeping the pipeline clean and extensible for future vulnerability types like SQL injection Deliverables include full codebase with documentation, a Postman collection for testing, and a proof-of-concept report from a real domain scan. I'm ready to start immediately. Let's discuss the details. Thanks, Denis.

Hi Puedo desarrollar este módulo como un microservicio de seguridad integrable con vuestro SaaS mediante API REST, priorizando resultados reproducibles y un reporte coherente con el MVP existente. Recomiendo Python/FastAPI para implementar el pipeline: validación y autorización del dominio, detección controlada de puertos/servicios, pruebas XSS no destructivas, integración con DeHashed/LeakCheck, normalización de hallazgos y generación automática de PDF/HTML. Las pruebas activas se limitarán a dominios autorizados por el usuario. Diseñaría conectores independientes para cada proveedor de inteligencia, con gestión de rate limits, reintentos, timeouts, logs y manejo seguro de credenciales. Los hallazgos tendrán severidad, evidencia, explicación técnica y recomendaciones, además de un resumen ejecutivo. Revisaré el informe del MVP y la plantilla proporcionada para unificar estructura y campos. Entregaré código documentado, README, colección Postman, API preparada para integración y una prueba de concepto sobre un dominio autorizado. Best, Justin

Hi, I’m Dev Singh, a Principal Software Engineer with 20+ years in AI, security-focused software and backend development. I have gone through your specific requirement for a SaaS security scanning module. I would use a Python REST service with isolated scan jobs rather than tying scans to web requests, since long scans and API limits can otherwise hold up the portal. I will build the Python service to check authorized domains for exposed ports and XSS, then query DeHashed or LeakCheck within their API limits. I can add PDF/HTML reports, structured logs, a Postman collection and setup notes, with scan modules kept separate so SQL injection checks can be added later. I can send project details and screenshots privately. Can you share the report template and the online MVP URL, including a test login if needed? Do you already have DeHashed or LeakCheck API access, and which one should be used first? Will you provide a domain you own or have permission to scan for the proof of concept? Free for a quick call? Or answer here and I will map out the first version. Dev Singh

Lo difícil aquí no es solo escanear un dominio, sino consolidar puertos, XSS y fugas en DeHashed/LeakCheck en un flujo único, estable y extensible dentro de tu SaaS, sin romper límites de rate‑limit ni la estructura de informes que ya tienes. Tengo experiencia desarrollando módulos SaaS y microservicios en Python/Node.js, integrando APIs externas, manejando límites de uso y generando reportes PDF/HTML a partir de datos técnicos (logs, payloads, respuestas de servidor). Ese enfoque encaja bien con tu MVP y la plantilla de informe que quieres unificar. Mi enfoque: 1) Diseñar un microservicio REST que reciba dominio/subdominio. 2) Ejecutar escaneo de puertos y XSS con herramientas/bibliotecas específicas. 3) Consultar DeHashed/LeakCheck con manejo de rate‑limit y consolidar hallazgos. 4) Generar reporte PDF/HTML siguiendo tu plantilla, con resumen ejecutivo y detalle técnico. Riesgo clave: falsos positivos en XSS o datos incompletos de las APIs. Lo mitigaría con validaciones y marcado claro de nivel de confianza. Preguntas: • ¿Tenéis preferencia por Python o Node.js para integrarlo en vuestra arquitectura actual? • ¿Qué proveedor usaréis para PDF (libería interna, servicio externo)? • ¿Necesitáis multi‑tenant desde el primer día o un solo tenant por ahora? Si te encaja este enfoque, puedo preparar el módulo listo para integrar en tu SaaS. Juan Pablo
