Most Asked Questions

Can someone hack me with my IP address?

Not directly. While your IP reveals approximate location and ISP, it doesn't provide device access. However, use VPNs and keep systems updated for enhanced security.

Should I use a VPN all the time?

It depends on your needs. VPNs are essential on public WiFi and for privacy-conscious users. For banking or streaming, consider your specific requirements.

What's the difference between HTTP and HTTPS?

HTTPS is encrypted HTTP. The "S" means "Secure" - your data is encrypted between your browser and the website, protecting sensitive information.

How do I know if my VPN is working?

Check your IP address before and after connecting to the VPN. If it changes to the VPN server's location, it's working. Use our VPN detection tool for verification.
