(150) Microsoft Intune - Windows Defender Firewall has blocked some features of this app

A customer reached out to me yesterday, after installing Webex and when trying to run the application, they got this message.

Solution 1:

The other way through a Win32 app would be:

Install.ps1

New-NetFirewallRule -DisplayName "Allow Webex" -Direction Inbound -Program "C:\program files\cisco spark\ciscocollabhost.exe" -Action Allow -Profile Any

Detect.ps1

try{
    if (Get-NetFireWallRule -DisplayName "Allow Webex" -ErrorAction Stop)
    {
        write-host "Success"
        exit 0  
    }
 
}
catch{
    $errMsg = $_.Exception.Message
    write-host $errMsg
    exit 1
}

Then wrap the app up with https://github.com/Microsoft/Microsoft-Win32-Content-Prep-Tool to get it uploaded to Intune deployment

Solution 2:

The easiest thing I could think of is using 'Windows Firewall Rules' is to navigate to https://intune.microsoft.com/ then Endpoint Security then Firewall then select Create Policy. Then select Platform: Windows then select Profile: Windows Firewall Rules. The Windows Firewall Policy you want to use is 'Windows Firewall allows administrators to define granular Firewall rules. Define firewall rules with specific ports, protocols, applications and networks, to allow or block network traffic.'. Select Create.

Under Basics, give it a name of the policy:

Under Configuration settings, select Add then select Edit Settings. Enabled: Enabled

Interface types: Remote Access, Wireless, LAN File Path: C:\program files\cisco spark\ciscocollabhost.exe Network Types: FW_PROFILE_TYPE_DOMAIN, FW_PROFILE_TYPE_PRIVATE, FWPROFILETYPEPUBLIC

Direction: This rule applies to inbound traffic

Then click Save.

Under Firewall Rule Name, select Next.

Review your settings then select Save. Go to your device on Company Portal, and it will create this rule for you in Firewall.
