FIREWALL & ADBLOCK

Firewall & Adblock will only work with KNOX. Be sure your phone has Knox before trying to use the Firewall & Adblock. If you are unsure if your Samsung device supports Knox, check the model number here. Be sure to see if it says supported or not because all Samsung devices are on the list, marked either supported or not.

The firewall gives you a lot of options to control what comes in and out, and is designed to give you finely-tuned control over all the apps on your phone. You can filter rules by tapping the horizontal yellow lines in the top-right. To search for something specific, tap the magnifying glass and use keywords to find what you’re looking for. The firewall can:

  • Per-Package/App Policies
  • Block/Restrict Wi-Fi, Data, or all network access
  • Add custom rules
  • AdBlock
  • AdBlock custom rules


To enable the firewall or adblock, flip the switches along the top. The icon on the main screen will have 2 parts of the flame lit depending on what you have enabled. If you enable the firewall, the bottom flame will be green. If you enable adblock and firewall, then both flames will be green (as shown above).

To use the larger list for ad blocking you can enable the Beta Ad List, but keep in mind – this is a test list. To enable it, select the 3 dot menu in the top-right and check Beta Ad List:


To add new rules to the firewall, click the + button at the top. You have the options to block: Domain Names | Apps | IPs


Entering a domain rule:

  • Enter the domain you would like to block
    • Example: yahoo.com
    • Select ‘www’ to include www.yahoo.com
    • Select all sub-domains to block (i.e. news.yahoo.com, sports.yahoo.com, mail.yahoo.com, etc)
    • If you want to block the domain from an application, uncheck the box and type in the app name you want to block, and it will auto complete with a list of apps on your device
    • If you want this rule to be applied to All apps on your device, leave the last option checked


Application rule:

  • Start typing the name you want, and it will auto complete with a list of apps on your device
  • Choose app and select the rule you’d like to apply:
    • Block Mobile
    • Block WiFi
    • Block All


Block IPs (still in development):
