ProtonVPN, a leading VPN provider, has released a new Stealth Protocol to help its users evade censorship in the global online space. The new protocol is designed to obfuscate user traffic and protect users’ privacy. The Stealth Protocol was developed in collaboration with the OpenVPN project and is based on the same security principles as OpenSSL, which is used by many of the world’s leading VPN providers. ProtonVPN says that it has been tested and proven to be effective against censorship threats, including China’s Great Firewall. The Stealth Protocol is available now and can be installed on ProtonVPN clients devices and servers. It can be used to access blocked websites, including in China, Russia, India, South Africa, and more.


ProtonVPN has released a new VPN protocol the company claims will help citizens in countries with censored internet to contact the outside world without risk of interception. Called the Stealth Protocol, it’s available now for all ProtonVPN users, including those on the service’s free plan.

According to Andy Yen, the company’s founder & CEO of Proton: “Internet censorship has become an arms race.” As certain governments try to control the internet—Iran and Russia spring to mind—more and more people are bypassing these restrictions using VPNs. Authorities, in turn, have taken countermeasures against VPNs, like identifying VPN traffic.

The Stealth protocol is the next step in this arms race: it can disguise traffic, making it look like a regular connection, without the tell-tale signs a VPN leaves. ProtonVPN is not the first to do so: VyprVPN, for example, offers the Chameleon protocol to do something similar, and the Shadowsocks proxy protocol can also make its connection look like regular traffic.

What sets ProtonVPN apart, in this case, is that it’s offering its technology for free. It also claims that using the Stealth protocol comes without a drop in performance, which makes it especially interesting for people dealing with poor internet infrastructure. To use the new protocol, simply go to the security settings in your ProtonVPN app, find the “Protocols” menu and select “Stealth.”
