How can a WiFiRanger improve security on public WiFi?

Yes. There are two aspects of security when dealing with public WiFi. The first has to do with the security of your data going from your laptop or tablet to your own WiFi router. Then there’s the security of the data going from your router to the WiFi access point.  With regard to the first part of the security issue, WiFiRanger products are designed to utilize state-of-the-art security protocols (called WPA2 and WPA3) to encrypt and protect the information on the internal network created between your devices and the WiFiRanger. As for the connection to the park’s WiFi, even if the park doesn’t have an encrypted network, a WiFiRanger can protect you by creating a Virtual Private Network (VPN) between your WiFiRanger and the WiFiRanger servers in Idaho. We call this capability SafeSurf and, unlike commercial VPN services, this one doesn’t cost you a penny to purchase or use.
