Please Use a VPN on Public WiFi

Standard

I’m sure you’ve heard the term VPN, which stands for Virtual Private Network.  Most people are familiar with it in the context of connecting remotely to their work network.  For those that aren’t familiar with a VPN, here’s a word picture I often paint to describe what a VPN does.

VPNThink of a four lane highway as the public Internet.  All the cars traveling on this highway are equivalent to each person’s Internet traffic.  As one car passes another, you can look at or in the car and possible see some of what’s there.  This is akin to unencrypted traffic traveling across the Internet, it can be seen and watched by others.  This is why sending sensitive information across the Internet is not safe, as it may be seen by those it’s not intended for.  When you use a VPN, your Internet traffic is sent across an encrypted connection.  Think of an encrypted connection as being like those pictures you see in Car and Driver Magazine when they publish “spy” reports on the next model year of vehicles.  The vehicles are typically wrapped to conceal what they actually look like and the windows may be tinted so darkly that you can’t see inside.  This is like encrypted traffic on the Internet.  You know it’s there, but you can’t tell what it is.  When you establish a VPN, it’s even better.  It’s like putting a tunnel over one of the four lanes on the highway.  The “public” traffic is happily driving along three of the lanes, able to see one another and get where they are going.  The traffic that is being sent across the VPN is being sent in the new tunnel that has taken over one of the lanes.  You know there is traffic there, but you can’t see it or access it.  It can only be seen at it’s starting and ending points.  It’s the safest way to send data, especially sensitive data.

When you connect to a wireless hotspot in a public location like a town square, a restaurant, hotel, etc., you are connecting to a very “public” network.  You should never log in to your bank or other sensitive site over a public wireless network.  Unless you are using a VPN.  If you use a VPN when connecting to these public networks, then you can safely connect to secure sites and protect your traffic from being seen by others.  I have used a VPN for years, for this very reason.

There are many excellent VPN’s on the market, but I am very excited that a company I trust a lot, Webroot, has a VPN specifically designed for WiFi.  Webroot has been an innovator in the cybersecurity space for years.  Their anti-virus/anti-malware tool, Webroot SecureAnywhere is a leader.  They have now added Webroot WiFi Security.  If you already have an anti-virus/anti-malware solution that you are happy with, you can add any VPN easily.  If you are looking for a better anti-virus/anti-malware solution and a VPN, there is a great bundle of both available as well.

I encourage you to check out Webroot’s WiFiSecurity.  Whether you decide to use that solution or another VPN, just pick one and stick with it.  You’ll be glad you did and a whole lot safer as well.
