employing a VPN at least once a month."Generally speaking, a modern online VPN is a service that is designed to encrypt your entire computer's traffic and at the same time hide your identity by routing your traffic through one or more anonymous routers," explains Yaniv Balmas, the head of cyber research at Check Point.
"We tested the top 150 free VPN Android apps and found that many had serious security flaws and performance issues," warns Callum Tennent, a VPN expert and the site editor at Top10VPN.com.
In other words, a large number of free or cheap VPNs may be doing the exact opposite of what we expect from them, collecting and exposing our data rather than hiding it. Of course, it would be bad enough if only free and untested VPNs had severe privacy issues. But the thing is, even when we're using a highly reputable and well-developed VPN, we're still not entirely safe from intrusions into our virtual privacy. And this will be of particular concern to journalists, dissidents, radicals, whistleblowers or anyone else who doesn't want a national government keeping tabs on them.
