View and manage SSL decryption exclusions . There are two types of decryption exclusions, predefined exclusions and custom exclusions:
- Predefined decryption exclusions allow applications and services that might break when the firewall decrypts them to remain encrypted. Palo Alto Networks defines the predefined decryption exclusions and delivers updates and additions to the predefined exclusions list at regular intervals as part of the applications and threats content update. Predefined exclusions are enabled by default, but you can choose to disable the exclusion as needed.
- You can create custom decryption exclusions to exclude server traffic from decryption. All traffic originating from or destined to the targeted server remains encrypted.

Adda Decryption Exclusion
Hostnameto define a custom decryption exclusion. The hostname defined here is compared against the SNI requested by the client or the CN presented in the server certificate. You can also use a wildcard asterisk (*) to create a decryption exclusion for all hostnames associated with a domain. Sessions where the server presents a CN that contains the defined domain are excluded from decryption.
Hostnames should be unique for each entry—if a predefined entry is delivered to the firewall that matches an existing custom entry, the custom entry takes precedence.
You cannot edit the Hostname for a predefined decryption exclusion.
Sharedto share a decryption exclusion across all virtual systems in a multiple virtual system firewall.
While predefined decryption exclusions are shared by default, you can enable and disable both predefined and custom entries for a specific virtual system.
Optional) Describe the application that you are excluding from decryption, including why the application breaks when decrypted.
Exclude the application from decryption. Disable this option to start decrypting an application that was previously excluded from decryption.

Disableone or more predefined decryption exclusions.
Because decryption exclusions identify applications that break when decrypted, disabling one of these entries will cause the application to be unsupported. The firewall will attempt to decrypt the application and the application will break. You can use this option if you want to ensure certain encrypted applications do not enter your network.

More about obsolete entries:
Updates to predefined decryption exclusions (including the removal of a predefined entry) are delivered to the firewall as part of Applications and Threats content updates. Predefined entries with
Exclude from decryptionenabled are automatically removed from the list of SSL decryption exclusions when the firewall receives a content update that no longer includes that entry.
However, predefined entries with
Exclude from decryptiondisabled remain on the SSL decryption list even after the firewall receives a content update that no longer includes that entry. When you
Show obsoletes, you will see these disabled predefined entries that are not currently being enforced; you can remove these entries manually as needed.
