      Opera VPN sends a TLS request to http://api.surfeasy.com  probably to get credentials it uses when talking to http://de0.opera-proxy.net .

      http://de0.opera-proxy.net  can only be resolved from Opera when VPN is on, it's 185.108.219.42. It's an HTTP/S proxy which requires auth.

      When loading a page with Opera VPN enabled, the browser sends a lot of requests to http://de0.opera-proxy.net  with Proxy-Authorization header.

      These creds can be used with the http://de0.opera-proxy.net  even when connecting from a different machine, it's just an HTTP proxy anyway.

      When you use the proxy on a different machine (with no Opera installed), you'll get the same IP as when using Opera's VPN, of course.

      This Opera "VPN" is just a preconfigured HTTP/S proxy protecting just the traffic between Opera and the proxy, nothing else. It's not a VPN.

          They even call it Secure proxy (besides calling it VPN, sure) in Opera settings. #Opera #VPNpic.twitter.com/0sU8nln1qP

          @spazef0rze for the purpose of web surfing, what protections are absent in Opera solution comparing to "real" VPN?

          @ivladdalvi It's missing a VPN. It's just a proxy for Opera, leaking IP address via WebRTC, with possible tracking via device id.

          @spazef0rze WebRTC could be disabled (may be, when turning on VPN). VPN naturally tracks users via authentication. Are there other issues?

          @ivladdalvi Besides false sense of security? Probably not.

          @PaulMishin Haven't heard about it, thanks. Froma very brief check it seems it's also a proxy. Let's see if I can dig deeper.

          @spazef0rze still, to put these 3 functions together is a really good concept, I think

          @PaulMishin Fortunately they don't advertise VPN as part of their product, or I can't find it.

          @spazef0rze But that's the whole point. It isn't supposed to be system-wide. It's only for the actual browser. So what's the big deal here?
