Apple chooses the path of isolation for iOS. Apps are only available on the official App Store, third-party vendors are not allowed to delve into the system. So there is no real antivirus. What we recommend, however, are two more apps for added security.
A VPN service like our test winner NordVPN also allows you to surf securely on hotspots and access streaming services abroad. A password manager like Bitwarden is also a good idea.
If you’re already using another password manager on Windows, chances are there’s an iOS app for that too. Feel free to browse our latest test. Admittedly, the key ring is essential on the iPhone, but it only offers comfort in the Apple world.
