Last week, an article was published regarding VPNs and Proxies
and potential vulnerabilities with WebRTC. We felt the article
was somewhat misleading, and we want to take the opportunity to
clarify what this all means and how it impacts you as a user of
SumRando's products and services.
What is WebRTC?
WebRTC is an HTML5 specification that allows for real-time
communication between browsers and devices without plugins or
other widgets installed. It enables voice and video communication
to work inside web pages. Many popular browsers (think FireFox
and Chrome) already have WebRTC enabled.
What is a Web Proxy?
A web proxy server is a computer that sits between you and the
internet, which reroutes your requests through our servers by way
of the website on the browser. When you are using a web proxy,
Internet traffic on that page is routed through the proxy server,
making it look as if it came from the server's IP address instead
of yours. This is isolated to only the webpage you are using, not
the entire browser.
What is a VPN?
VPN stands for virtual private network. VPNs provide a virtual
version of a secure physical network, where the information you
send over the Internet is encrypted and secured from others on the
Internet. By running a VPN, an encrypted tunnel is established
between your device and the VPN servers. Once the connection is
established, all of your Internet activity (from browser to Skype
to email) is pushed through this secure tunnel, through the VPN
servers, and out to the Internet. The video on our VPN page - https://www.sumrando.com/vpn.aspx
- explains the process as well.
Great. Why are you telling me all this?
The article that was originally published last week and has since
circulated in the community indicated that some privacy services
(VPNs and Proxies) may be vulnerable to WebRTC leaks. SumRando
Web Proxy was identified on that list.
Was my IP leaked when I used SumRando VPN?
No. SumRando is designed to encrypt ALL traffic including WebRTC
offering you the most anonymity and security possible when using a
Was my IP leaked when I used SumRando Web Proxy?
Potentially, depending on the website(s) you visited. SumRando Web
Proxy was released with the intention of circumventing geolocation
blocking and for quick anonymous searches on the web. It was not
designed to serve as a complete privacy and security solution.
(That's why we encourage you to download and use SumRando VPN).
Admittedly, we weren't clear on our website how the browser plays
a big role in network communication and the risks related to
WebRTC and other non-HTTP and HTTPS web traffic.
I used SumRando Web Proxy. Can you tell me if I was specifically
impacted by the leak?
No. SumRando does not track SumRando Web Proxy activity. We have
no insight into who visited what sites at any certain time.
Okay. Now what?
We highly recommend that you download and use SumRando VPN - https://www.sumrando.com/download.aspx
We have a free account option that provides you with 1GB of data
per month. If you need more, you can easily upgrade to SumRando
VPN Platinum, which gives you unlimited data and access to all of
our VPN servers around the world.
SumRando Web Proxy is temporarily unavailable while we work to
determine is there are additional ways to reduce the impact of
WebRTC. If you are concerned with WebRTC, it is possible to
disable it directly in your browsers - https://www.privacyend.com/disable-webrtc-in-various-browsers/
This may degrade some performance of websites, but it will prevent
other websites from obtaining more inforamation under the guise of
