Device security is of paramount importance to enterprises. It’s why the Android Security team (and many other teams at Google) continuously work to improve protections across more than 2 billion active Android devices.

To ensure customers, partners, and Android users are up to date on our ongoing work, we recently published the fourth annual Android Security Year in Review. This document details improvements to Google’s security offerings in Android, updated platform features, and key metrics that inform our initiatives.

While the report provides a broad view of the breadth of the security work across the ecosystem, there are important highlights for our enterprise users.

Enterprise-grade security in Android

In 2017 we launched Google Play Protect, Android’s built-in device, data, and apps security scanning technology. Google Play Protect protects users from potentially harmful apps (PHAs) in real-time and uses cloud-based services for analyzing device and app data to identify possible security concerns.

Every day, Google Play Protect automatically reviews more than 50 billion apps, other potential sources of PHAs, and checks devices, warning users about potential harm. These automatic reviews enabled us to remove nearly 39 million PHAs last year.
