Palo Alto – Device Groups vs Templates

In the context of Palo Alto Networks’ Panorama, “Device Groups” and “Templates” serve distinct purposes but are essential components of its centralized management functionality. Let’s break down the differences:

Device Groups

Purpose: Device Groups are used primarily for policy management.

Main Points:

  • Hierarchical Structure: You can create a hierarchical structure with device groups, allowing you to have parent and child groups. This hierarchy facilitates the inheritance of policies, which means child groups inherit the policies of their parent groups.
  • Security and NAT Policies: You can define and manage security and NAT policies for firewalls within a device group. These policies determine how traffic is handled (allowed, denied, NAT’ed, etc.) by the firewalls associated with that device group.
  • Objects Inheritance: Objects like address objects, service objects, and tags can be shared within device groups and can also be inherited due to the hierarchical structure.


Purpose: Templates are used for configuration management of device settings.

Main Points:

  • Shared Configuration: Templates allow you to define shared configurations for multiple firewalls. This might include settings related to interfaces, zones, SNMP settings, DNS, NTP, and more.
  • Stacking: Palo Alto introduced the concept of “Template Stacks.” This allows you to group multiple templates together in a specific order, and when applied to firewalls, they inherit configurations from all the templates in the stack in the defined order.
  • Force Template Values: As we discussed earlier, when pushing a template, you have the option to “Force Template Values” which would ensure the firewalls take the exact configurations from the template, potentially overwriting local configurations.


  • Device Groups are all about policy: Who can access what and how traffic is treated as it traverses the firewall.
  • Templates deal with configuration settings: How the firewall is set up, what interfaces it has, what zones are defined, and other system-level configurations.

Both Device Groups and Templates are crucial for managing a large number of firewalls efficiently. By using them in tandem, network administrators can ensure consistent policy enforcement and configuration across all devices, while also allowing for specific customizations where needed.
