    Where Can I Use This?What Do I Need?
    • Prisma Access (Managed by Strata Cloud Manager)
    • Prisma Access license
    • Administrator access to the endpoint for installing the machine certificate
    • Trusted PKI certificate deployed on endpoint
    Pre-logon is a connect method that establishes a VPN tunnel before a user logs in. The purpose of pre-logon is to authenticate the endpoint, not the user, and enable domain scripts or other tasks to run as soon as the endpoint powers on. Machine certificates enable the endpoint to establish a VPN tunnel to the GlobalProtect gateway. A common practice for IT administrators is to install the machine certificate while staging the endpoint for the user. A pre-logon VPN tunnel uses a generic pre-logon username because the user has not logged in. To allow endpoints to access resources, you must create security policy rules that match the pre-logon user. These policy rules should allow access to only the basic services for starting up the system; for example, DHCP, DNS, specific Active Directory services, antivirus, or other update services. After the user authenticates to the gateway, the GlobalProtect app reassigns the VPN tunnel to that user. The IP address mapping on Prisma Access changes from the pre-logon endpoint to the authenticated user.
    The certificate used for pre-logon authentication resides in the endpoint’s personal certificate store. Use a trusted third-party CA, self-signed CA, or an internal PKI CA to issue a machine certificate. You need to configure a machine certificate as an authentication method to establish a tunnel from an endpoint before logging in to Prisma Access, and then create a certificate profile that includes the pre-logon CA certificate.

    Configure Pre-Logon Certificate and Profile

    Configure a machine certificate as an authentication method to establish a tunnel from an endpoint before logging in to Prisma Access, and then create a certificate profile that includes the pre-logon CA certificate.
    1. Configure a self-signed CA, and use it to generate a machine certificate in the Mobile User template. Go to DeviceCertificate ManagementCertificates.
      Be sure that you're in the Mobile_User_Template and the Location is set to Shared.
      1. Name the certificate; for example, Pre-logon CA Cert.
      2. Enter a Common Name.
        The Common Name (CN) is the domain name, such as www.yourdomainname.com, you want to secure with your certificate.
      3. Leave the Signed By field blank, and click the Certificate Authority check box.
      4. Generate the certificate for use in Pre-logon connections.
    2. After you configure the self-signed CA, generate the machine certificate.
      1. Enter a Certificate Name and a Common Name.
      2. In the Signed By drop-down, select the Pre-logon CA Cert that you created in step 1.
      3. Generate the Windows VM Machine Certificate that you later install on a Windows machine.
        This certificate is a child of the Pre-logon CA.
