    PAN-OS 8.1 Decryption Cipher Suites

    List of cipher suites supported for IPSec on firewalls running PAN-OS® 8.1 in normal operation mode.
    The following table lists cipher suites for decryption that are supported on firewalls running a PAN-OS® 8.1 release in normal (non-FIPS-CC) operational mode.
    If your firewall is running in FIPS-CC mode, see the list of PAN-OS 8.1 Cipher Suites Supported in FIPS-CC Mode.

    SSL/TLS Decryption—Perfect Forward Secrecy (PFS) Ciphers
    If you use the DHE or ECDHE key exchange algorithms to enable PFS support for SSL decryption, you can use a hardware security module (HSM) to store the private keys used for SSL Inbound Inspection.
