What I have read is that Opera's VPN is not a true VPN service, but a proxy. I am not technically inclined, that's the reason why I post this question on this forum: is it too good to be true? And is the information below correct?
An additional link to a review that made me question how truly effective this free VPN service is? https://proprivacy.com/privacy-service/review/operavpn
The most important quote from the review link above:
OperaVPN is proxy, not a VPN service. Connections are secured using HTTPS, the encryption scheme which protects sensitive websites, making OperaVPN an HTTPS proxy. Because it is based on Chromium, the Opera browser supports TLS 1.3. This is the latest version of the protocol, and it is reasonable to assume that the VPN also uses TLS 1.3.
