It might be tempting to connect to the nearest public Wi-Fi network when you’re away from your home or office, but too often the risks can outweigh the benefits, especially when accessing business application and data.

To learn more, I recently sat down with Jon Wong, Samsung’s director of B2B mobile product marketing, in New York.

“Public Wi-Fi is primarily designed for convenience, not security,” explained Wong. “What that means is that the data going through those networks is more prone to attacks.”

While the best approach may simply be to not connect to public WiFi hotspots, says Wong, if you do need to connect then be sure to leverage a VPN. On Samsung smartphones and tablets, Knox also provides multilayered security that protects users from many of the attack vectors associated with public WiFi.
