Getting Started with Xfinity xFi Advanced Security

Managing Threats

Threats are split into two main categories: Those that are for awareness only and those that require attention.

Awareness-Only Threats

Some threats won’t require any action, but you will still be alerted. These include Suspicious Site Visits. To view additional details when no action is required, select the device from the Advanced Security dashboard.

The threat details page will provide a list of threats associated with a given device, for example when the device has been blocked from visiting a dangerous website.

Any time a device is blocked from accessing a site, you can opt to allow it to access. Keep in mind that by doing so, you may be putting your network at risk and making it vulnerable to malicious activity. Access will be limited to a certain amount of time due to this risk. Learn more about the threat types.

Threats that Require Attention

Some threats, such as a Targeted Network Attack, Suspicious Device Activity or Unauthorized Access Attempt, may require you to take further action. If a threat requires your attention, you’ll see an alert at the top of the Dashboard indicating how many require your attention. Select the device to access the threat details page and to take action.

The threat details page will provide a list of threats that have been blocked but require your attention to ensure they don’t return. Select Help Me Fix It for tips on how to resolve the threat. Learn more about threat types.


Tips to Resolve Threats

Depending on the nature of the threat that requires your attention, the following tips can help you take action to resolve the threat.

  • Quarantine Your Device

    If one of your devices has been compromised, you can use xFi to pause its access or disconnect it from your home network. This will keep it from endangering other devices on your network.

  • Update Your Software

    Keep your device’s software or firmware current to ensure you’ve got the latest security updates. Use the update feature usually found in your device’s settings or check with the device manufacturer.

  • Run Antivirus Software

    One of the best ways to defend against network threats is by running antivirus software. If you haven’t already, install a software program, keep it updated, and run scheduled scans to keep devices free from viruses. Learn more about how to Download Norton Security Online for your PC, Mac and Android devices.

  • Restart Your Device

    After updating your device’s software, be sure it restarts. This will complete the update and also, stop any existing communication with malicious sites.

  • Check Your Port Forwards

    Open ports on your home network give potential access to malicious attackers. Ensure your port forwards are set up correctly for your devices. Learn about port forwards and how to set them up using xFi.



Disabling Advanced Security

You can disable the Advanced Security feature in xFi by navigating to More and selecting My Services. From here, select Disable under xFi Advanced Security.

Once disabled, you will lose 24/7 threat monitoring and real-time reporting on your home network.

**Note**: You will still be subscribed to Advanced Security even if you disable it. To unsubscribe, call 1-800-xfinity.
