Free or public WiFi hotspots rarely use secure protocols and passwords. It is because of that public WiFi can be hijacked by hackers. Even if that’s not the case, hackers can create fake WiFi hotspots that are malicious. If any user joins a malicious network, their data, as well as online privacy, can be at risk. Therefore, users should use a virtual private network to bar hackers from breaching their devices or data. How? A VPN uses encryption and security protocols to protect data or network traffic against prying eyes. Now get PureVPN just for $0.99 and secure yourself on public WiFi.
