The entire network of servers is secured with a military grade AES 256-bit encryption which is the most advanced form of encryption available among VPNs today. BVPN also supports multiple advanced and unique security protocols including OpenVPN with UDP and TCP, SSH, L2TP with IPSec, and its very own Smoke Tunnel which we will discuss in more details later on. PPTP used to be supported, however, it is not anymore due to that it is not considered one of the secure protocols anymore.

Before we go into more details about Smoke Tunnel let us shine the light on the other protocols supported especially OpenVPN. Now the OpenVPN protocol supported by BVPN runs on both UDP and TCP. Not only that, but the user has the ability to switch between them by a single click without any throttling. In addition to that, BVPN was one of the very first VPNs to support OpenVPN on SSH Tunnel. This is a built-in feature made to bypass the toughest situations such as the Great Firewall of China and any Deep Packet Inspection undergone by governments for the core purpose of restricting websites. This is why BVPN is one of the highly recommended VPNs for locations such as China and Iran who have the highest levels of online censorship.

One of the main security features that caused BVPN to leap to a leading position in the market was that the BVPN client for iOS has a built-in OpenVPN client which makes it the first VPN application for iOS to support OpenVPN without the need to install a separate application for it.

Smoke Tunnel

Due to the rise of online censorship around the world by governments and their endless attempts to block VPN services, it has become an ongoing challenge for VPN services to play their key role in providing their users with online privacy, online security, and online freedom. For that reason, VPN service has been striving into developing new encryption technologies to assist in overcoming these strong restrictions, firewalls, and Deep Packet Inspections. When it came to BVPN, they were able to develop their own form of strong double encryption technology called “Smoke Tunnel”.

BVPN customized the User Datagram Protocol or UDP that is built into the client software to act as an additional layer of encryption. It is even stronger than the commonly used double encryption layers by other VPN providers. This is what Smoke Tunnel is. Smoke Tunnel works by completely hiding the OpenVPN connection and obfuscates network traffic to make it completely undetectable by tough firewalls such as the Great Firewall of China and Deep Packet Inspections.

An additional advantage of the Smoke Tunnel is that it fixes the connection speed by resolving any throttling problems which can be caused by different IPs and ports without affecting or interrupting the connection itself, providing the user with a stable and strong VPN connection for a longer period of time.

Kill Switch

In its latest versions of the application, BVPN has implemented a built-in internet kill switch which acts as an emergency measure if, for any reason, the VPN connection drops. In other words, if at any time the VPN connection drops, the kill switch disables the entire internet connection until the VPN connection is back online. This prevents any leaks from taking place due to the drop in the secure VPN connection. The user has the ability to either enable or disable this feature from the settings of the application. It is as simple as clicking to check or uncheck a checkbox.
