While some states have enacted their own privacy legislation, Illinois currently has limited protections. Being proactive about your digital privacy is particularly important.

To protect your privacy while browsing from Chicago, consider using a trusted VPN service that encrypts your traffic and masks your real IP address. Even in Chicago, public Wi-Fi at local cafes and public spaces can expose your data. A VPN adds a critical layer of encryption between your device and the internet. After connecting to your VPN, verify it's working properly with our VPN leak test — this checks for DNS, WebRTC, and IPv6 leaks that could expose your real Chicago IP address. You can also check your browser fingerprint to see how uniquely identifiable your browser is, even when using a VPN.
