Many providers that offer completely free VPNs will sneakily log and sell user data, and sometimes even bundle their clients with malware. (It's a classic "no free lunch" situation.) ProtonVPN and TunnelBear are two trustworthy options that offer free subscription tiers, but they're extremely limited in terms of their server selection and browsing data limit, respectively. Overall, free VPNs generally aren't worth it. The best way to get a VPN "for free" without putting yourself at risk is by subscribing to one, then making use of its money-back guarantee.
