When choosing a VPN you’re looking for speed, security, and privacy, and with free VPNs, you’re unlikely to get any of it. Such providers often don't allocate resources to their server networks, resulting in potentially unstable VPN connections and IP address leaks. Additionally, they need a means of generating revenue, which may involve selling user data in some instances. Rather than focusing solely on the lowest-cost option, prioritize finding a trustworthy VPN service provider.
