GlobalProtect Gateways

The PA-3020 in the co-location space (mentioned previously) also doubles as a GlobalProtect gateway (the Santa Clara Gateway). 10 additional gateways are deployed in Amazon Web Services (AWS) and the Microsoft Azure public cloud. The regions or POP locations where these AWS and Azure gateways are deployed are based on the distribution of employees across the globe.
  • Santa Clara Gateway—Employees and contractors can authenticate to the Santa Clara Gateway (PA-3020 in the co-location space) using 2FA. This gateway requires users to provide their Active Directory credentials and their OTP. Because this gateway protects sensitive resources, it is configured as a manual-only gateway. As a result, users do not connect to this gateway automatically and must manually choose to connect to this gateway. For example, when users connect to AWS-Norcal, which is not a manual-only gateway, some sensitive internal resources are not accessible. The user must then manually switch to and authenticate with the Santa Clara Gateway to access these resources.
    In addition, the Santa Clara Gateway is configured as a Large Scale VPN (LSVPN) tunnel termination point for all satellite connections from gateways in AWS and Azure. The Santa Clara Gateway is also configured to set up an Internet Protocol Security (IPSec) tunnel to the IT firewall in corporate headquarters. This is the tunnel that provides access to resources in the corporate headquarters.
  • Gateways in Amazon Web Services and Microsoft Azure—This gateway requires 2FA: a client certificate and Active Directory credentials. The GlobalProtect portal distributes the client certificate that is required to authenticate with these gateways using the GlobalProtect SCEP feature.
    These gateways in the public cloud also act as GlobalProtect satellites. They communicate with the GlobalProtect portal, download the satellite configuration, and establish a site-to-site tunnel with the Santa Clara Gateway. GlobalProtect satellites initially authenticate using serial number, and subsequently authenticate using certificates.
  • Gateways Inside Corporate Headquarters—Within the corporate headquarters, three firewalls function as GlobalProtect gateways. These are internal gateways and do not require endpoints to set up a tunnel. Users authenticate to these gateways using their Active Directory credentials. These internal gateways use GlobalProtect to identify the User-ID and to collect Host Information Profile (HIP) from the endpoints.
    To make the end user experience as seamless as possible, you can configure these internal gateways to authenticate users using certificates provisioned by SCEP or using Kerberos service tickets.
