Yes, in the vast majority of countries around the world, using a VPN is completely legal. They are legitimate tools for protecting personal privacy and security online. Many businesses also use them to allow employees to securely connect to the company network from remote locations. However, it is important to remember that while the tool itself is legal, using it to engage in illegal activities—such as hacking, downloading copyrighted material, or committing fraud—remains against the law. A few countries with highly restrictive internet policies, such as China, Russia, and North Korea, have laws that regulate or ban the use of VPNs.
