Use a VPN

Even if you re on a password protected network, there s still the possibility that someone will intercept your transmissions. To ensure absolute privacy, use a VPN service, which basically creates a network within a network just for you. Boingo offers a VPN through its subscription plans (from $9.95 a month) that lets you access more than 500,000 global hot spots. The new Norton Hotspot Privacy service ($49.99 a year) will also route all your traffic through a private connection.
