Security is always a top concern while dealing with sensitive data. Luckily, OpenVPN has an upper edge here as it uses 256-bit encryption keys and high-end ciphers. This gives good protection against the man in the middle attacks. As a result, it is rather difficult to grab the information by altering the data packet.
Similarly, OpenVPN can use any port on TCP or UDP, which makes it easily work with internet. Even when there are network firewall based blocks in place, it is difficult to block the OpenVPN connections. For example, if OpenVPN uses TCP with port 443, then the connection will appear as typical HTTPS connection and can easily pass through the firewall.
OpenVPN has cost advantages too. OpenVPN software is free for download and use in Windows, Linux, MacOS computers, as well as Android and iOS devices.
OpenVPN client allows to make free connection to a VPN server. Again, when we use it on a server to accept incoming VPN connections, OpenVPN gives free access from two clients.
