AT&amp;T ActiveArmor uses a proactive network security approach that encompasses both wireless and internet connections to ensure you&rsquo;re safe both online, and on your phone. Using <a href="/security/security-apps/" rel="noreferrer noopener" target="_self">our mobile app</a>, you can put security in the palm of your hand by enabling custom call controls, managing who&rsquo;s on <a href="/wi-fi/" rel="noreferrer noopener" target="_self">your Wi-Fi network</a>, scanning your network for vulnerabilities, and more. The app notifies you of any potential threats, offering guidance on the best course of action. Now you can talk, text and surf with confidence, knowing ActiveArmor has your back.&nbsp;

What if you need protection at work? AT&amp;T ActiveArmor advanced mobile security is also available for business customers.1 Contact your Account manager or owner to find out how to get it added to your phone line.

Fraudsters are continuously finding new ways to threaten customer data and device security. While 100% prevention is the goal, it&rsquo;s not guaranteed because the landscape is always changing. That&rsquo;s why we strive to continually evolve and improve our security efforts to help protect you, and help you protect yourself. You can always monitor which calls and text messages have been blocked in the app and adjust your settings accordingly.

With ActiveArmor Advanced, you can enable additional protections that can bolster your internet security. For example, you can activate Identity Monitoring to get alerts if your information is compromised1 and use Safe Browsing to block harmful websites while you surf.2 If you use public Wi-Fi, enabling Public Wi-Fi Protection helps encrypt your data to keep fraudsters from accessing it.3

At home, you can access even more protection with our Smart Home Manager app.4 Not only does it monitor suspicious behavior across all your connected devices, it can scan your network for vulnerabilities. You can also use it to control access to your Wi-Fi network and manage passwords. For even more privacy, you can connect to a VPN, use the Threat Activity Dashboard to monitor potential threats, and activate Advanced Content Controls to restrict access to certain websites and types of content.

While there are some similarities in ActiveArmor on your mobile device and your internet, there are also some key differences. For example, the free ActiveArmor app primarily blocks scam calls and texts on your phone. Upgrading to ActiveArmor Advanced offers additional protections that can affect your internet usage on your phone, like Safe Browsing, Public Wi-Fi Protection, Identity Monitoring.&nbsp;

Additional protections for home internet use come via the Smart Home Manager app, which can help you manage your wireless connection and passwords, monitor and manage device access, monitor suspicious activity across all your connected devices, and more.
