I've been using VPN for years and have already tried many services, both free and paid. Well, of course, you can choose a free one, but most of the IP addresses can be blacklisted, so it might happen that you won't have access to this or that source when needed. Also, I'm not sure a free VPN can really protect your data. Speaking about the paid VPN providers, there are five of them that are known to be the best for everything (working, storing data, watching content, torrenting, etc.): ExpressVPN, NordVPN, IPVanish, CyberGhost, and Surfshark. You can read the info about them here. Though if you ask Google about the top VPN services, you will get the same list. I haven't tried only CyberGhost. From my own experience, I can say that four others are great and worth every penny. By the way, there are frequent sales and discounts, so you can save a lot of money (last Black Friday I bought NordVPN at a 60% discount for two years).
