Protect your smartphone against threats

Learn how the AT&T Mobile Security app helps defend your smartphone against security threats.


Basic security features

App monitor
Scans your device proactively and warns you about potentially unsafe apps.

Breach reports
Sends email and app alerts when Mobile Security detects a data breach that may affect you. You’ll also get helpful tips about what to do next.

Email threat detection
Detects when there’s malware or spyware in email downloads and attachments. It doesn’t scan individual emails.

Malware scans
Looks for malware, like Trojans, worms, spyware, and ransomware on smartphones and apps. Plus, it actively monitors your files if you select File Security.

Passcode check
Checks if your smartphone uses a passcode to protect your device and data from unauthorized access.

System update
Lets you know if it’s time to update your phone’s operating system, or if something changes your smartphone’s operating system. If it finds an issue, you’ll get a notice and the Device Security section on the Mobile Security home screen will turn red. It stays red until you select Device Security to get more details about fixing the issue.

Threat alerts
Turns the affected feature’s icon red when Mobile Security identifies a threat to your smartphone.
  • You’ll get a notification and the icon will stay red until you act.
  • Selecting the icon gives you info about the threat and options to resolve it.
  • The app doesn’t automatically delete the files or apps.
  • If you check your files, you may also get pop-up alerts letting you know how to handle threats.

Good to know: AT&T Mobile Security doesn't flag viruses that don't harm smartphones.
