    Configure an SSL/TLS Service Profile

    Specify the certificate, TLS protocol versions, and cipher suites used to secure connections to various Palo Alto Networks services.
    Where Can I Use This?What Do I Need?
    • NGFW (Cloud Managed)
    • NGFW (PAN-OS or Panorama Managed)
    For cloud-managed NGFWs:
    Palo Alto Networks firewalls and Panorama appliances use SSL/TLS to secure connections to the Authentication Portal, GlobalProtect portals and gateways, the management interface, HTTPS websites that require password access (URL Admin Override), and the User-ID™ syslog listening service. You can create an SSL/TLS service profile to define the server certificate, SSL/TLS protocol versions, and ciphers supported for connections to these services. Cipher suites are automatically selected based on the protocol versions chosen. However, you can disable individual ciphers as needed. If a service request involves a protocol version outside the specified range, the firewall or Panorama appliance downgrades or upgrades the connection to a supported version. To activate an SSL/TLS service profile, attach the profile to the settings for a specific service.
    In the client systems that request firewall services, the certificate trust list (CTL) must include the certificate authority (CA) certificate that issued the certificate specified in the SSL/TLS service profile. Otherwise, users will see a certificate error when requesting firewall services. Most third-party CA certificates are present by default in client browsers. If an enterprise or firewall-generated CA certificate is the issuer, you must deploy that CA certificate to the CTL in client browsers.
    TLSv1.3 support is limited to administrative access to management interfaces and GlobalProtect portals and gateways. You can only attach SSL/TLS service profiles that allow TLSv1.3 to the settings for these services.
    Post-quantum cryptography (PQC) certificates are not yet available for selection in SSL/TLS service profiles as they are for testing purposes only.

    Configure an SSL/TLS Service Profile (Strata Cloud Manager)

    Configure an SSL/TLS service profile on Strata Cloud Manager.
    1. Log in to Strata Cloud Manager.
    2. For each desired service, generate or import a certificate.
      1. Select ManageConfigurationNGFW and Prisma AccessObjectsCertificate ManagementConfigurationNGFW and Prisma AccessObjectsCertificate Management.
      2. In the Custom Certificates pane, Generate or Import a certificate.
      3. Save the certificate.
    3. Configure an SSL/TLS service profile.
      1. Select ManageConfigurationNGFW and Prisma AccessObjectsCertificate ManagementConfigurationNGFW and Prisma AccessObjectsCertificate Management.
      2. In the SSL/TLS Service Profiles pane, click Add Profile.
      3. Enter a Name for the profile.
      4. Select or Import a Certificate.
        PQC certificates are not available for selection or import.
      5. For Protocol Settings, define the range of TLS versions that the service can use.
        TLSv1.3 support is limited to administrative access to management interfaces and GlobalProtect portals and gateways. You can only attach SSL/TLS service profiles that allow TLSv1.3 to the settings for these services.
        Administrative Access and GlobalProtect Portals and Gateways:
        Set the Min Version and Max Version to TLSv1.3.
        • For the Min Version, select the earliest allowed TLS version: TLSv1.0, TLSv1.1, TLSv1.2, or TLSv1.3.
        • For the Max Version, select the latest allowed TLS version: TLSv1.0, TLSv1.1, TLSv1.2, or TLSv1.3.
        All Other Services:
        Set the Min Version and Max Version to TLSv1.2.
        • For the Min Version, select the earliest allowed TLS version: TLSv1.0, TLSv1.1, or TLSv1.2.
        • For the Max Version, select the latest allowed TLS version: TLSv1.0, TLSv1.1, or TLSv1.2.
    4. (Optional) Select any Key Exchange Algorithms, Encryption Algorithms, or Authentication Algorithms.
      (PAN-OS 12.1 only) For Key Exchange Algorithms, select the Classical or Post-quantum Cryptography (PQC) tab.
      The RSA, DHE, and ECDHE classical key exchange algorithms are enabled by default.
      (TLSv1.3 only) To specify PQC key exchange algorithms, click Add, and then configure the following settings:
      1. For Algorithm, select ML-KEM.
      2. For each algorithm, select at least one Security Level: Level 1, Level 3, Level 5.
        These levels are based on NIST standards of security strength. The higher the security level, the greater the security provided.
      3. For each algorithm, define the PQC Supported Groups by selecting one or more curve groups.
        The curve groups available for selection differ based on the selected Algorithm and Security Level.
      4. Save the PQC key exchange algorithm.
    5. Save the profile.
    6. To commit your changes, click Push ConfigPush.

    Configure an SSL/TLS Service Profile (PAN-OS & Panorama)

    PAN-OS: Specify a certificate, TLS protocol versions, and ciphers that you want connections to various Palo Alto Networks services support.
    1. For each desired service, generate or import a certificate on the firewall (see Obtain Certificates).
      Use only signed certificates, not CA certificates, in SSL/TLS service profiles.
    2. Select DeviceCertificate ManagementSSL/TLS Service Profile.
    3. If the firewall has more than one virtual system (vsys), select the Location (vsys or Shared) where the profile is available.
    4. Click Add and enter a Name to identify the profile.
    5. Select the Certificate you obtained in step one.
      PQC certificates are not available for selection.
    6. Under Protocol Settings, define the range of TLS versions that the service can use.
      TLSv1.3 support is limited to administrative access to management interfaces and GlobalProtect portals and gateways. You can only attach SSL/TLS service profiles that allow TLSv1.3 to the settings for these services.
