Google Play Protect is a set of features that will ensure your device is always secure. This isn’t just behind-the-scenes, though, as the point of Play Protect is to allow the user to really see what’s taking place in the process. For example, inside of Google Play, a user can scan all of their apps manually with Play Protect, on top of allowing it to work automatically.
It is a security package for Android devices consisting of app scanning, browser protection, and anti-theft measures. The app scanning feature is actually built into any device that comes with the Google Play Store, it doesn’t need to be installed or activated separately and it doesn’t need any manual input to work. This is an always-on service, said to scan 50 billion apps per day across a billion Android devices to ensure they are safe.
Google Play Protect makes attempts to verify app security at the point at which they are uploaded to the Play Store too, but this alone does not guarantee eternal safety. And so, Google also makes use of daily scans and machine learning algorithms to help stay one step ahead of any potential threats, if it does encounter a malicious app, it can disable it to prevent further problems.
