Having all your traffic encrypted means that your online activity can’t be monitored and all of your information is secure. Anyone intercepting your traffic won’t be able to decipher it. Without a VPN, your Internet Service Provider (ISP) can see everything you do online, including the sites you visit, applications you use, and files you download. They can’t do this when you’re using a VPN.
This also means that others who may be monitoring the network can’t see your activity. This could be a network administrator (for example, in a school or office), a government agency, or a hacker. The lattermost might be a particular threat if you tend to travel a lot and frequent public wifi hotspots. Hackers are known to lie in wait on unsecured networks waiting to steal your information. To stay safe, you should use a VPN every time you connect to an open wifi network.
With a VPN, you can carry out your normal online activities without worrying about prying eyes. This includes browsing, streaming, torrenting, gaming—anything you do that involves an internet connection. Many businesses use VPNs as a means of securing communications and processes, ensuring sensitive information isn’t leaked and reducing vulnerability to hackers.
You might be wondering if a VPN is legal. Indeed, it’s perfectly legal to use VPN in almost every country.
