What it does: Antivirus/VPN
What it solves: Hotspot security
Have you ever done something at a hotspot you shouldn't have? Maybe you checked your credit card account or you logged into your bank to check your account status. On public hotspots, this is risky. Hotspot Shield combines an antivirus program with the privacy capabilities of a VPN. Hotspot Shield encrypts your connection to a Wi-Fi network, and you can use it with mobile devices.
