Welcome to a new episode of Ask ZDNetwhere we tackle the questions that even Google can’t solve.
In the mailbox this week: why should I consider a VPN?
The advantage of this type of network is twofold. First, it prevents someone on your local network from spying on your internet traffic. That’s especially important if you’re using a Wi-Fi network that’s out of your control.
Second, you can hide your location, which prevents some types of tracking and also allows you to bypass geo-restrictions on some services. If you’re in Europe and want to watch a movie that is limited to the US, you may be able to fool the streaming service by connecting to a VPN in the US.
VPNs are labor intensive and can take a huge toll on your network bandwidth. Therefore, you should only use them when you need them.
When I’m at an airport or hotel, I prefer to connect my cell phone to my laptop (or bring a device with a built-in cellular connection) to avoid the risks of that untrusted network. But if the mobile signal is weak or unavailable and I have no choice but to connect to that public wifi, I use the paid Fast VPN service from NameCheap. My colleague Jason Perlow uses ExpressVPN†
“It’s compatible with OpenVPN, an open source VPN protocol,” he says, “meaning I can use it with all the devices I own — iOS, Android, Windows, even my network firewall.”
Whichever option you choose, nothing in that virtual private network looks for threats to your PC. For that kind of protection, you need security software specifically designed to detect malicious software and dangerous connections.
