AT&T Mobile Security scans the apps and operating system on your device and notifies you if certain threats are detected. If an unsafe app or file is found while an app is being installed, 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.
System Advisor confirms that your operating system contains the latest operating system software updates. The System Advisor feature will detect if your device has been rooted,6 which makes it vulnerable to security threats.
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 tunnel for your data when you are using open Wi-Fi hotspots 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 the 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.
It means your data connection is not encoded. Unencrypted data sent over the internet can be intercepted by hackers.
Your home Wi-Fi and Wi-Fi at your work location are most likely encrypted. Secure Wi-Fi VPN will not deploy on these connections. Secure Wi-Fi VPN will not deploy on already secure connections.
Secure VPN will disconnect automatically when you leave open Wi-Fi networks.
If you have more than one VPN tool/feature on your device, Secure W-Fi VPN will not activate if another VPN is already in use. Conversely, if you manually activate another VPN service, Secure Wi-Fi VPN will deactivate and allow the third-party VPN feature to turn on.
Some Wi-Fi hotspots require you to log in to a portal before you can access the Wi-Fi hotspot. If you are having issues getting the Wi-Fi hotspot to connect, try to open a browser and type in the name of the business (for example, https://starbucks.com) to try to trigger the portal. If that doesn’t work, try something like www. Google.com to force it to open so you can connect to the Wi-Fi hotspot.
Due to restrictions by some video streaming services, video streaming data may be directed outside of the Secure Wi-Fi VPN service while all other traffic will continue through the encrypted VPN tunnel.
Secure Wi-Fi VPN is provided on an “as-is” basis with no warranties and makes no representations of any kind, express or implied, with respect to the Secure Wi-Fi VPN.
As an additional layer of protection on Android devices, a feature called Wi-Fi Alerts is available for PLUS customers to send you a notification if a Wi-Fi hotspot you are trying to join is potentially unsafe and could hurt your privacy.
Theft Alerts warn you when suspicious activity is detected on your Android smartphone, indicating your smartphone may have been stolen. You will be provided instructions on what to do if your device is lost or stolen.
Alert triggers are customizable by:
Once the alert is triggered, an email will be sent including the location of your device and how to suspend service. For Android smartphones, a photo taken using the front-facing camera is included in the message.
Please note: Theft Alerts is not available on iOS.
Millions of U.S. consumers have had their personal information compromised in data breaches. With Breach Reports, you will receive timely information on data breaches by looking at the apps on your device to provide information. If a company is breached:
As part of the System Update feature, you will be notified if your Operating System is out of date and prompted to update it now.
Updating your operating system is an important security feature for your mobile phone. The software updates sometimes contain important fixes to security flaws and system vulnerabilities. This could prevent your phone from being hacked and prevent your data from being shared unwillingly.
The passcode check feature will ensure you have a passcode set up correctly to keep your device and data secure.
The most important thing you can do to keep your device and data secure is lock the device with a unique PIN or a biometric fingerprint.
You may block up to 200 numbers manually.
There is no limit to the amount of numbers you can add to your Personal Block list.
