<br/>

is a website security scanner. It performs comprehensi checks by analyzing HTTP security headers, TLS certificates, common TCP ports, and technology stacks. Built with scalability in mind, it utilizes an asynchronous architecture to handle concurrent scans efficiently and generates professional PDF reports for its findings.

> Defensive Use Only: is strictly for posture checks and configuration analysis. It does not exploit , run offensi, or automate attacks. Always ensure you ha to scan a target.

Key Features

* Comprehensi Modules:
* SSL/TLS: Certificate expiry, chain trust, hostname match, key strength, negotiated TLS , and cipher checks.
* HTTP Headers: HSTS, CSP, X-Frame-Options, cookie flags, and ser analysis.
* Port Scanning: Fast, asynchronous TCP probes on curated port lists to identify exposed risky services (e.g., Telnet, RDP, Redis).
* Technology Fingerprinting: Passi of underlying technologies, CMS platforms, and frameworks and body signatures.
* Subdomain Enumeration: Passi of associated subdomains using Subfinder and OSINT sources.
* Production-Grade Architecture: Background job processing via Celery and Redis ensures the API remains lightning-fast, while PostgreSQL provides persistent job and result history.
* Professional Reporting: Export detailed findings, se summaries, and module-specific data as highly polished PDF reports using WeasyPrint and Jinja2.
* Modern Frontend: A beautiful, responsive UI built with React 19, Vite, and Tailwind CSS v4 for managing scans and reports.
* Security Built-in: SSRF mitigation prevents scanning of private/loopback targets. Optional API key authentication protects your endpoints. Safe socket interactions without subprocess or shell execution.

Architecture

completely decouples the web routing from the hea scanning logic to guarantee maximum throughput and non-blocking I/O.

Tech Stack

* Backend: FastAPI, Pydantic, SQLAlchemy, Alembic
* Workers: Celery, Redis
* Database: PostgreSQL
* Scanning Engines: httpx, cryptography, standard library ssl/socket
* Report Generation: Jinja2, WeasyPrint
* Frontend: React 19, Vite, Tailwind CSS, TanStack React Query

Quick Start (Docker)

The fastest way to get up and running is using Docker Compose.

Prerequisites

* Docker & Docker Compose

Running the En

1. Clone the repository:

2. Start the backend services:

3. Apply database migrations (required on the first run):

A Services:
* API Server:
* Interactive API Docs (Swagger UI):

En Configuration

Set up your .env file to customize the deployment. See .en for defaults.

| | Description | Default |
|----------|-------------|---------|
| DATABASE_URL | PostgreSQL connection string | postgresql://... |
| CELERY_BROKER_URL | Redis connection string | redis://... |
| API_KEY | Secret key to protect API endpoints (optional) | None |
| BLOCK_PRI | Enable SSRF protection against internal IPs | True |
| CORS_ORIGINS | Allowed CORS origins (JSON array string) | [" ...] |

📖 API Reference

1. Create a New Scan

POST /api/v1/scans/

*Returns 202 Accepted with a scan_id.*

2. Check Scan Status

GET /api/v1/scans/{scan_id}
*Poll this endpoint to retrie status (PENDING, RUNNING, COMPLETED, FAILED) and the final structured findings.*

3. Download PDF Report

GET /api/v1/reports/{scan_id}/pdf
*Returns the finalized PDF report for a COMPLETED scan.*

Security Philosophy & Disclaimer

is built with a defensi mindset:
* Authorization First: Only scan systems you own or ha authorization to assess.
* SSRF Protection: By default, rejects targets resolving to internal or private IP ranges to prevent abuse of the scanning infrastructure.
* Non-destructive: Scans employ standard network requests and client libraries without executing shell commands or dropping payloads.
* No Subprocess: Python's native socket, ssl, and httpx modules are used exclusively, eliminating OS-le injection risks.

Roadmap

[ ] Add Subdomain Enumeration module.

[ ] Implement DNS Rebinding protections for the worker nodes.

[ ] Package Frontend inside a multi-stage Docker container for all-in-one deployment.

[ ] Add Webhook support to notify clients when a scan completes.

[ ] Support custom HTTP User-Agent definitions per scan.
