A software firewall only protects your data on your computer, and anti-virus software only protects you from, well, viruses. Neither protects your data as it flows over your local network, at a Wi-Fi Hotspot, or through your ISP. Without a VPN, your data is completely exposed and can easily be monitored and captured.

As laptops, smartphones, and wireless networks have grown more popular, a great deal more data has become a great deal more mobile.
