Entrust nShield hardware security modules (HSMs) integrate with Next-Generation Firewalls to securely generate and store master keys and private keys. As the nShield client-side software for PAN-OS® 11.2 and earlier versions approaches its end-of-support date, organizations face compliance and service continuity issues. To address these issues, PAN-OS 12.1 upgrades the legacy Security World software to version 13.6.3. Security World 13.6.3 ensures FIPS 140-3 compliance and is compatible with both older and newer nShield HSM models integrated with Palo Alto Networks. This compatibility ensures that nShield HSM operations remain uninterrupted and modernizes your HSM infrastructure through security and functionality enhancements.
