TheAnti-spyware profileincludes DNS-based protections like sinkholing and detection of DNS queries to malicious domains, offering real-time protection against attacks that exploit DNS misconfigurations.
"The Anti-Spyware profile protects against DNS-based threats by sinkholing DNS queries to malicious domains and detecting suspicious DNS activity, thus blocking data exfiltration and C2 communication." (Source: Anti-Spyware Profiles)

Client-based VPNsolutions like GlobalProtect provide full coverage for the mobile workforce by extending the enterprise security stack to remote endpoints. It establishes a secure tunnel, allowing consistent security policies across the enterprise perimeter and the mobile workforce.
"GlobalProtect is a client-based VPN that provides secure, consistent protection for mobile users by extending the security capabilities of Prisma Access to remote endpoints, covering all network protocols." (Source: GlobalProtect Admin Guide)

Adecryption policyallows the firewall to inspect encrypted traffic and apply security controls toPost- quantum Cryptography (PQC)usage, as PQC algorithms are typically implemented within encrypted sessions.
"Decryption policies enable the firewall to see and control encrypted traffic. This visibility and control extend to new cryptographic algorithms, including PQC, to ensure that security measures are applied consistently." (Source: Palo Alto Networks Decryption Overview) By decrypting sessions, you ensure that even PQC traffic can be inspected, logged, and subject to security profiles for visibility and policy enforcement.

Palo Alto Networks requires upgrading to thenext major feature releasebefore moving to newer releases.
This ensures stability and compatibility.
"When upgrading across multiple major PAN-OS releases, you must upgrade to each intermediate major feature release. Skipping major releases is not supported." (Source: Upgrade Considerations) For PAN-OS 9.1 # 11.2, the proper path is:
9.1 # 10.0 # 11.2

Acomprehensive security approachuses:
* User-IDfor identity-based policies
* App-IDfor application-based security
* Decryptionto inspect encrypted traffic
* Security profilesto enforce protections
* Dynamic updatesto ensure up-to-date threat coverage
"For comprehensive security, combine User-ID, App-ID, decryption, and security profiles. Keep the firewall updated with dynamic content updates to maintain the strongest security posture." (Source: Best Practices for Security Policy) This ensures real-time, identity-aware, and application-centric security enforcement.
