AT&T Mobile Security FAQ

  • How is my Android device protected from unsafe apps and files?

    AT&T Mobile Security scans Android apps and the operating system and notifies you if threats are detected. If an unsafe app or file is found during installation, during a security scan, or while actively monitoring file systems, the Security tab on the Dashboard will turn red until you take action.

    Note: Apps and files are not automatically deleted when threats are detected.  You are responsible for taking appropriate action to remove or remediate any detected threats.

  • Does my Android device have the latest operating system installed?

    The System Advisor feature confirms that your Android operating system contains the latest operating system software & security updates. It will detect if your device has been rooted,* which makes it vulnerable to security threats.

    *Not guaranteed to detect or prevent roots or other unauthorized app installation(s).

  • What is Secure Wi-Fi VPN and why do I need it?

    Secure Wi-Fi VPN helps protect your data when you are using an open (unencrypted) Wi-Fi connection.

    Open (unencrypted) Wi-Fi connections may exist in restaurants, hotels, airports, etc. The Secure Wi-Fi VPN creates a private tunnel for your data when you are using an open Wi-Fi hotspot to protect you from Wi-Fi snooping during important tasks like email, financial transactions, and browsing the web.

    Secure Wi-Fi VPN only works in the United States including Puerto Rico, Hawaii, and U.S. Virgin Islands. It does not work when using certain video streaming apps.
    For a complete list see the AT&T Mobile Security Terms and Conditions.
