Welcome to another installment of Ask ZDNet, where we tackle the questions even Google can’t solve.
In the mailbag this week: Why should I consider a VPN?
The benefit of this type of network is twofold. First, it prevents anyone on your local network from spying on your internet traffic. That’s especially important if you’re using a Wi-Fi network that’s not under your control.
Second, it allows you to disguise your location, which prevents some types of tracking and also makes it possible to bypass geographic restrictions on some services. If you’re in Europe and want to watch a movie that’s restricted to the US, you might be able to fool the streaming service by connecting to a VPN in the US.
VPNs are resource-intensive and can take a huge toll on your network bandwidth, which is why you should only employ them when you need them.
When I’m in an airport or hotel, I prefer to tether my mobile phone to my laptop (or bring a device with a built-in cellular connection) to avoid the risks that come with that untrusted network. But if the cellular signal is weak or unavailable and I have no other choice than to connect to that public Wi-Fi, I use the paid FastVPN service from NameCheap. My colleague Jason Perlow uses ExpressVPN.
“It’s compatible with OpenVPN, an open source VPN protocol,” he says, “which means I can use it with all the devices I own — iOS, Android, Windows, even on my network firewall.”
Regardless of which option you choose, nothing in that virtual private network looks for threats to your PC. For that sort of protection, you need security software that’s specifically designed to sniff out malicious software and dangerous connections.
