9. Hotspot Shield: To Secure Your Wi-Fi in Public
VPNs have a few different uses. One is to secure your connections on public networks such as Wi-Fi hotspots or wired Internet ports.
While connected to a VPN, all your Internet traffic goes through the secure tunnel to the endpoint (your office).
Therefore, if you use a VPN while on an unprotected network, all your Internet traffic is encrypted by the VPN tunnel.
Hotspot Shield protects against any nearby eavesdroppers or hackers.
