Why Choose This Project

Network administrators and security enthusiasts often need to check open ports on servers or devices to identify potential vulnerabilities. This project provides a simple web-based interface to scan IP addresses or domains for open ports, helping users identify potential security risks and monitor network exposure without needing complex command-line tools.

What You Get

• A responsive web interface to scan a single IP or a range of IPs.

• Port scanning functionality for common ports (HTTP, FTP, SSH, SMTP, etc.).

• Scan results display with open/closed status for each port.

• Export option to save results as CSV or PDF.

• User authentication & session management (optional).
