What is OpenVPN?
OpenVPN is an open-source tunneling protocol that uses OpenSSL, a cryptographic library, to secure communication over the internet.
OpenVPN can be used in different configurations, depending on the preference and goals of the user.
The OpenVPN encryption length supported by OpenVPN is up to 256 bits. It can use certificates, usernames/passwords, or pre-shared keys for authentication purposes.
The strongest security it provides is through the use of certificates.
OpenVPN’s security protocol is different from those used by L2TP and IPSec, as it relies only on SSL and TLS for security and encryption of communication.
SSL and TLS are virtually impenetrable OpenVPN encryption standards, which is where the real strength of OpenVPN as a secure tunneling protocol stems from.
Users can visit the OpenVPN community to discuss configuration and development-related issues regarding this protocol. This is one of the reasons why the open-source VPN protocol has gained so much popularity.
Is OpenVPN Safe?
OpenVPN is one of the safest VPN protocols to use. This is because it uses AES for encryption, which is a powerful encryption standard.
However, OpenVPN is not entirely untouchable, and governments can block VPN traffic through OpenVPN.
This is because the use of OpenVPN can be identified through Deep Packet Inspection (DPI). With strict online regulations, DPI is often used to find and block users’ traffic using an OpenVPN-based service to bypass state-imposed website restrictions in countries like China and Russia.
It is possible to deal with the problem of DPI and still be able to use OpenVPN. This can be done by disguising OpenVPN traffic as HTTPS by routing it over port 443, associated with HTTPS traffic. This is the simplest “obfuscation” method that VPNs generally use.
Other obfuscation methods, such as Obfsproxy, are more reliable than simply routing OpenVPN over port 443. Generally, OpenVPN is sufficient for online privacy and security in democratic countries where internet traffic is free and not heavily monitored.
However, in countries that treat VPN traffic suspicion, you might experience difficulties getting your VPN to work with OpenVPN enabled.
In these cases, you will require obfuscation features to have any chance of accessing the web with the VPN.
What Can You Do with an OpenVPN VPN?
With OpenVPN, you can do pretty much everything that a VPN was designed for. This includes browsing the web with stronger privacy and encryption to avoid having to worry about your online activities and identity being scrutinized by third parties such as governments, agencies, advertisers, and cybercriminals.
Another important benefit of OpenVPN is its ability to bypass internet censorship and restrictions on websites.
With OpenVPN, you can browse the web unhindered by any geo-restrictions or other blockades, making for a free open-access online experience.
Thus, whether it is better privacy you seek or free access to the internet, OpenVPN has all the bases covered.
What Makes OpenVPN Better than Other Protocols?
OpenVPN is the only open-source VPN protocol. As a result, the versatility of this protocol is unmatched.
Furthermore, the VPN has been repeatedly audited by experts worldwide, establishing it as the most reliable and trusted VPN protocol.
The use of digital certificates and hash authentication allows OpenVPN to offer much higher levels of security and encryption than other protocols.
In addition, most other protocols have to compromise between security and speed. OpenVPN provides the perfect balance of both, enabling fast speed without compromising on the strength of security.
Disguising yourself through OpenVPN SSL
Although decrypting the content of your traffic is almost impossible, ISPs can still find out whether you are hiding behind an OpenVPN connection or not.
As it turns out, the OpenVPN protocol is equipped to deal with this problem, using a particular TCP configuration.
OpenVPN TCP over port 443 cloaks all traffic moving through the VPN. Port 443 is normally used for HTTPS (SSL) traffic, which is invisible to ISPs.
As such, OpenVPN configured to run this way will make it considerably difficult for your ISP to detect you are using OpenVPN.
How to Set Up OpenVPN
OpenVPN can be set up in two different ways. The first method that I’m going to show you is much simpler, and I would recommend it for users who are not technically inclined.
Dedicated OpenVPN Apps
All leading providers offer dedicated clients who have built-in support for OpenVPN. These clients are extremely easy to set up: users can select the OpenVPN protocol with a single click and even change to other tunneling protocols like PPTP, L2TP, SSTP, etc.
The VPN providers listed above all have their dedicated apps. So all you need to do is download and install software (VPN app) of the provider on your system and device so if you want to use an Open VPN service in the easiest way possible.
You can set up Open VPN connection services using third-party clients like OpenVPN GUI as well. This is an open-source OpenVPN client that can be used to configure your VPN.
Almost every major VPN offers .ovpn files, which you need to configure that VPN using OpenVPN GUI.
Once you download and install these files, you can use the VPN through the OpenVPN GUI. If you have difficulty finding .ovpn files of your preferred VPN service, contact customer support.
More often than not, they are happy to provide you with the lives and even assist with the setup process.
Open VPN Compatibility with Major Platforms
Most premium VPN providers offer cross-platform compatibility. In addition, some providers go the extra mile and offer compatibility with routers, gaming consoles, and media streaming devices.
Open VPN for Windows
It is easiest to find an Open VPN service for Windows. Every provider that is worth mentioning has at least a dedicated VPN Windows client for the Windows platform.
So, you should have no trouble getting an Open VPN server setup clients from the official website of your VPN provider.
If your VPN service is too backward to have a native VPN client, you can use Open VPN GUI to run the VPN through .ovpn files.
Open VPN for Mac
The story with Mac compatibility is a little bit different. Although many VPNs have dedicated apps for Mac, this isn’t a general rule.
For instance, all the virtual private networks on the list above offer native Open VPN clients, except Surfshark.
You can use a third-party client such as Tunnelblick for those VPNs that do not have a dedicated VPN client compatible with macOS.
Open VPN for Android
Like Windows, Open VPN apps for Android are really easy to find and are available for hundreds of providers. In addition, almost every popular VPN has its Open VPN app available on the PlayStore.
Nonetheless, if you are interested in a provider that doesn’t have an Open VPN app for Android, you can use this third-party client. It is easy to use and does not require rooting/jailbreaking your Android device to get it to work.
Open VPN for iOS
Apple has an inexplicable fondness for L2TP protocol, set up by default on all iOS devices. However, many VPN apps support Open VPN for iOS.
OpenVPN Connect is a good third-party app for iOS, which will allow you to configure Open VPN for those VPN services lacking a native client for iOS.
Open VPN for Router
Some VPNs can be set up on a router itself, which adds VPN protection to your network at the router level. Simply connecting to such a router puts you under the protection of the VPN you have configured.
Though only a few routers support Open VPN connections, the setup process is quite tricky and detailed for those who do.
If you are interested in installing an Open VPN connection on your router, read my DD-WRT router VPN setup instruction.
What ports need to be open for OpenVPN?
OpenVPN uses ports 443 and 1194. These ports should be open for OpenVPN to work. This isn’t usually a problem, but if you suspect these ports are blocked, ask your ISP to look into it, and it should get resolved.
Is OpenVPN good?
Currently, no protocol offers a better combination of security, reliability, and speed than OpenVPN. So, yeah, OpenVPN is VERY good.
Is OpenVPN free?
The OpenVPN open source project might be free, however commercial use of OpenVPN is not free. You are welcome to try the OpenVPN Access Server which is free to install and offers 2 simultaneous connections as a trial.
What is OpenVPN used for?
OpenVPN is used for securing and encrypting data that is sent over the internet so that users can keep their confidential information safe during an exchange from third-parties.
What is difference between VPN and OpenVPN?
OpenVPN is an open source software solution which helps in implementing the use of VPNs. A VPN on the other hand allows you to get access to restricted websites and other numerous facilities which you cannot access for whatever reason.
The security and performance of the top-tier VPNs have considerably improved thanks to the OpenVPN protocol.
However, while many VPNs offer Open VPN services, it still depends on how the provider configures this protocol to enable optimum security and speed.
With the VPNs mentioned above, you can elevate your security and take advantage of the OpenVPN protocol to the fullest.
