Kandji

Kandji is purpose built MDM application used to deploy apps and services remotely to macOS devices. To learn more about Kandji and their MDM platform, visit: Kandji Support website.

This article illustrates the procedure to deploy Netskope Client on macOS devices running Big Sur or later using the Kandji MDM as the IdP. This process ensures reduced user interaction while deploying tenant certificates, system and network extensions.

Prerequisites to using Kandji

Setup Netskope for IdP
Download Netskope Certifications (Root and CA)
Download VPN Proxy App script from the Netskope Support Portal. This is required for macOS devices running Big Sur or later
Administer role access to Kandji

Download Netskope Certificates

Login to Netskope WebUI with admin access and go to Settings > Security Cloud Platform > MDM Distribution. Download both the root and Netskope intermediate certificate.
Convert the downloaded certificates to .cer format by renaming the .pem files to .cer.

Creating Deployment Scripts in Kandji

Deployment scripts are a combination of audit script and remediation script that are required to deploy Netskope Client to the end user devices. The audit script checks if Netskope Client is installed on the end-user devices and the remediation script installs the clients on end-user devices that do not have the client installed.

Go to Library > Add New > Custom Script and Configure

Create custom script with the following parameters:

Execution Frequency : Set this to value that suits your environment.

Audit Script

#!/bin/bash
#script for installing NSAgent on OSX machines
#will check to see if Netskope is Installed
function Test_NSClient(){
    xz=$(/usr/bin/mdfind kMDItemFSName == Netskope Client.app -onlyin /Library/Application\ Support/)
 
    if [ -e "$xz" ]; then
        echo "$xz found netskope client is installed"
    exit 0
    else
        echo "client does not exist"
    exit 1
    fi
 
}
Test_NSClient 
#end script

Remediation Script

Replace the values marked XXXXX with tenant domain name and YYYY with the tenant name.

spDomain= <goskope_domain> ; Example: goskope.com
spTenant = <tenant_name> ; Example: If your tenant URL is example.goskope.com, then enter only example.
If you are installing using multi-user mode, add “perusermode” parameter in the script.

#!/bin/bash
#Script for installing Netskope Client on OSX machines
#function will install Netskope Client
function Ins_NSClient(){       
    ag="NSClient.pkg"       
    spDomain="XXXXX"       
    spTenant="YYYYY"   
    
    perusermode=0 # put 0 for normal installation, put 1 for per user config             
    
    echo "Downloading NsAgent..."       
    curl -o /tmp/$ag  https://download.goskope.com/dlr/mac/get                   
    
    echo "will now add config file..."       
    mkdir -p "/Library/Application Support/Netskope/STAgent"       
    NSIDPCONFIG_FILE_PATH="/Library/Application Support/Netskope/STAgent/nsidpconfig.json"       

    echo "{ \"serviceProvider\": { \"domain\": \"$spDomain\", \"tenant\": \"$spTenant\" } }" > "${NSIDPCONFIG_FILE_PATH}"  
    
    if [ $perusermode -eq 1 ]   
    then       
    NSUSERCONFIG_JSON_FILE="/Library/Application Support/Netskope/STAgent/nsuserconfig.json"       

    echo "{\"nsUserConfig\":{\"enablePerUserConfig\": \"true\", \"configLocation\": \"~/Library/Application Support/Netskope/STAgent\", \"token\": \"\", \"host\": \"\",\"autoupdate\": \"true\"$fail_close_option}}" > "${NSUSERCONFIG_JSON_FILE}"   
    fi
        
    echo "Installing Agent..."       
    installer -dumplog -pkg /tmp/$ag -target / && rm /tmp/$ag
}
