Why Choose This Project

In enterprise environments, VPNs are widely used to provide secure remote access. However, monitoring VPN connections is critical to detect suspicious activity, unauthorized logins, or potential breaches. This project creates a VPN connection logger that tracks user sessions, connection times, IP addresses, and device information. Alerts are generated for unusual patterns, failed logins, or connections from unexpected locations, ensuring secure remote access management.
