I use Proton VPN. Not sure what level of security you're looking for but if it's truly sensitive data it offers a hop through Switzerland and absolutely cutting edge encryption.
It's not the cheapest and it doesn't play well with Linux sometimes but if you're just looking for a software base VPN you can't go wrong. Now is a good time to buy as well as there's a lot of competition in the market.
Just don't go free vpn or your data becomes the payment method, you'll be guaranteed slow performance, no recourse or support for problem. Make sure the package you buy supports the number of clients you'll be using it on including tablets, desktops and smartphones.
Also, check for discount codes as they almost all have one before paying full retail. If I'm not mistaken Mozilla also just came out with their on VPN and they've always been reliable as far as privacy.
