Hi @gustavosj This topic was already discussed a lot here. In some cases there are solutions and (unfortunately) in other cases there is almost no way to do everything completely transparent to the user. So lets try it this time with your situation 😉 But before we recommend you something that does not apply to your environment, I kindly ask you to answer these questions: Does this dialog only appears in case of connection problems or also right after the installation is complete? What PAN-OS version do you have installed on your portal and gateway? As you specified pre-logon, you already use certificates, right? User or client certificates? What additional authentication are you using (ldap, radius, ...)? You're trying to hide everything completely from the users eyes, so I assume you aren't using any multi-factor-authentication? (TOTP, SMS, ...) What GP agent version do you use? Does your company already have a SAML IdP infrastructure (e.g. Microsoft ADFS)?
