Best VPNs for iPhone and iPad (for speed and security)

In this guide you will be able to analyze the best VPNs for iPhone and iPad in terms of speed and security, so that you can only install secure VPN apps and test and avoid VPN apps that cannot be traced to the company or the type of secure connection used.
Why use a VPN on iOS and iPadOS
A VPN can be a great way to protect the privacy of iPhone users and iPad: even though Apple's operating system is currently one of the most effective in protecting user privacy, it can do nothing about the data traffic that passes through the Wi-Fi network or the cellular data network.
A Internet provider can discover all the sites that an iPhone or iPad user visits, as well as a government agency; an attacker can capture the data traffic exchanged between the user's phone and the Wi-Fi network (often a public hotspot), thus stealing access passwords and precious files. By adding a VPN it is possible to block any attempt to violate privacy, since the connection will be encrypted and unassailable from the device to the requested web server.
