Two Factor Authentcation for Palo Alto VPN Client

miniOrange provides a ready to use solution for Palo Alto Platform. This solution ensures that you are ready to roll out secure access to Palo Alto to your employees within minutes.

Palo Alto VPN client

Palo Alto provides Global Protect system which connects to the Virtual Private Network (VPN) at UMass Amherst. It provides an encrypted connection between your campus network and off-campus computer. You can enable two-factor authentication (2FA) for your Palo Alto managed active directory to increase security level. When you enable 2FA, your users enter their username and password (first factor) as usual, and they have to enter an authentication code (the second factor) which will share on your virtual or hardware 2FA solution.
To enable 2FA you can enable RADIUS authentication in Palo Alto and configure policies in miniOrange to enable or disable 2FA for users.

miniOrange 2FA for VPN Login

  • miniOrange accomplishes this by acting as a RADIUS server, that accepts the username/password of the user entered as a RADIUS request, validates the user against the user store as Active Directory ( AD ), prompts him for the 2-factor authentication and either grants/revokes access based on the input by the user.

  • Types of 2FA Authentication with RADIUS

  • The 2-factor authentication can be of two types depending on the VPN clients.

    • VPN Clients that support RADIUS Challenge.
    • VPN Clients that do not support RADIUS Challenge.

  • In VPN Clients that support RADIUS Challenge :

    • First step is user's username & password get validated against the credentials stored in Active Directory and 2nd request sends a success response, this request is sent to validate the 2-factor authentication of the user, on successful authentication user is granted access to the application.
    • Authentication methods : All Authentication methods supported by miniOrange. Software Token, Push Notification, OTP over Email to name a few.
    • RADIUS Clients that support this authentication type:
      -> OpenVPN
      -> Palo Alto
      -> Fortinet
      -> Pulse Secure Connect Secure SSL
    • MFA for VPN Client: palo-alto-support-chart

    We can connect with any Directory

    miniOrange provides user authentication from external directories like Microsoft Active Directory, Azure AD, AWS Cognito etc.

    Can't find your Directory ? Contact us on idpsupport@xecurify.com. We'll help you setting it up in no time.
