TPM is a hardware-based cryptographic module integrated into many modern Palo Alto firewall models, including the PA-460, PA-3410, and PA-5430 series. Unlike software-based key storage, TPM generates and stores cryptographic keys entirely within the tamper-resistant hardware itself. Private keys never leave the TPM—they cannot be exported or copied. When the firewall needs to prove its identity, the TPM performs cryptographic operations using its internal keys. including the PA-460
