VPNCheck Pro is a lightweight Windows and Linux security utility developed by Guavi that acts as an automated kill switch and identity protector for your virtual private network (VPN). Unlike actual VPN services that route your internet traffic, this software sits on top of your existing VPN to prevent data leaks if your connection unexpectedly drops. Core Features
Automated Kill Switch: Instantly closes specified applications or completely shuts down your network adapter the exact moment a VPN crash is detected.
OpenVPN & PPTP Auto-Login: Automatically logs you back into OpenVPN and PPTP protocols to restore your secure tunnel.
Application Management: Offers customizable options to automatically run or close an unlimited number of programs depending on your VPN status.
Computer ID Protection: Generates new computer IDs and alters hostnames/MAC addresses to protect against Wi-Fi WPA/WPA2 backdoors and tracking techniques.
Virtualization Support: Operates seamlessly inside virtual environments like VMware and VirtualBox.
Leak Detection: Fixes DNS leaks and monitors local IP changes for router VPN pass-through. VPNCheck Free vs. Pro
While a Free Edition exists, the Pro version unlocks critical security elements: VPNCheck Free VPNCheck Pro OpenVPN Support DNS Leak Fix Supported Programs Max 3 programs Identity Protection Computer ID & MAC spoofing System Requirements
Windows: Compatible with older and modern versions of Windows. Linux: Requires MonoFramework 4.5+ (tested on Ubuntu).
Note: Many modern commercial VPN providers now build native kill switches and DNS leak protection directly into their own applications, which may make standalone utilities like VPNCheck Pro redundant unless you are configuring manual OpenVPN/PPTP connections.
