VulnShield

Web Application Vulnerability Scanner

 ** Project Status: Active Development**

VulnShield is an ongoing cybersecurity project designed to simulate web application security assessments and penetration testing workflows.

The project provides an interface for initiating security scans, analyzing common web application security controls, tracking scan results, comparing previous scans, and generating structured security reports.

Core functionality has already been implemented, while additional vulnerability checks, testing, documentation, and improvements are still being developed.
