When you connect to a public WiFi, it is risky to transmit sensitive data across the network. The best practice is to never log into your bank accounts or enter passwords while on public WiFi.
But with a Virtual Private Network using secure OpenVPN technologies, your data is encrypted. If a hacker monitors your network, he will not be able to break through this secure tunnel. Your ISP or government won’t be able to read your data or spy on you as well.
OpenVPN is one of the most widely used types of open-source encryption technology. It uses a custom security protocol with SSL/TLS for key exchange, creating secure point-to-point or site-to-site connections. OpenVPN can run over User Datagram Protocol (UDP) or Transmission Control Protocol (TCP) tunnel transports. This makes your web traffic indistinguishable from the traffic using standard HTTPS over SSL, and it is therefore extremely difficult to detect and block.
Due to its strong features, ease of use, and extensive support, OpenVPN became one of the most popular VPN software solutions. Here are more characteristics of the protocol:
VPNs tend to support the OpenVPN protocol, since it’s quite streamlined, offers compelling benefits to both users and providers, and thus has become increasingly mainstream. To many paid VPN providers, it is the default protocol.
One of the reasons for OpenVPN's popularity is its security. It uses custom OpenSSL-based security technologies, providing encryption similar to that on HTTPS sites. OpenVPN can be configured to use any port, which makes it indistinguishable from normal internet traffic, allowing it to bypass VPN blocks. OpenVPN also supports a number of encryption algorithms, from Blowfish to AES.
VPN Unlimited supports OpenVPN both via the TCP and UDP ports. These are two Internet protocols that have a huge impact on performance.
While OpenVPN can work on any port, it works best over a UDP port. UDP does not allow the receiver to acknowledge receipt of data or request a resend. Due to this, connection and data transfer speed increases. But when using unreliable networks, it is better to switch to TCP.
TCP is a transmission control protocol. Unlike UDP, it makes sure that the data is received in the correct form and order and re-requests the data if it is lost. This improves reliability by increasing latency.
If the choice between OpenVPN TCP and UDP isn’t clear, it is suggested to try UDP first. If you face connection or stability issues, you can switch to TCP anytime. To increase security on your iOS devices, we recommend you enable our special technology, KeepSolid Wise that operates via the UDP and TCP ports as well.
The downside is that all this encryption and security negatively affects users’ connection speed. This makes OpenVPN a sub-optimal option for speed-sensitive services, e.g. video streaming.
Get KeepSolid VPN Unlimited and use OpenVPN technologies operating through secure TCP or UDP ports.
