WiFi Security in the United States
Defend My WiFi springs into action whenever you connect to public WiFi hotspots. These locations are favorites among hackers who use scary sounding techniques like WiFi Spoofing and Honeypot attacks tocompromise your digital life.
Defend My WiFi protects you by enabling a Virtual Private Network, or VPN. VPN technology prevents untrusted parties from seeing what you are doing on your phone.
