Oracle Cloud has a free tier and this video shows you how to set up your own VPN there. I wouldn’t really recommend this as a free VPN solution though. If you need something that’s free, go with Proton VPN’s free tier, Proton is pretty trustworthy and they are very upfront about their business model…
IVPN created an awesome website called doineedavpn.com where they honestly and objectively answer that question. It’s one of the reasons why I like IVPN as a VPN provider, they are honest and don’t hide anything from their customers. Also their apps are open source and they support anonymous signup.
