To install the Vanta Agent via Powershell you would first run this command to download the agent:

Invoke-WebRequest -Uri https://app.vanta.com/osquery/download/windows -OutFile vanta.msi

and then run the following command to install and register the agent to a user. Note that you will have to replace "vantaSecret" with the key available on the computers page, and "userEmail@company.com" with the user's email address that exists in Vanta:

msiexec /i vanta.msi /passive /qn VANTA_KEY=vantaSecret VANTA_OWNER_EMAIL=userEmail@company.com

Here is an example PowerShell script that could be deployed to install the Vanta Agent:

$vantaSecret= "vanta_key"
$userEmail= "email@domain.com"

try {
Invoke-WebRequest -Uri https://app.vanta.com/osquery/download/windows -OutFile vanta.msi
}
catch {
"Unable to Download the Vanta Agent. Please ensure that script is being run as an administrator"
}
try {
msiexec /i vanta.msi /passive /qn VANTA_KEY=$vantaSecret VANTA_OWNER_EMAIL=$userEmail
}
catch {
"Unable to install the Vanta Agent. Please ensure that the Vanta Secret is correct"
}
Finally {
"Successfully installed the Vanta Agent"
}
