TheSP3 architectureof Palo Alto NGFWs ensures that additional security services (CDSS) only cause aminor reduction in performance, as traffic is inspected once in a single pass.

“The single-pass parallel processing (SP3) architecture performs application identification and security enforcement simultaneously in one pass, resulting in only minor performance impacts when enabling multiple security services.”

Unlike traditional multi-pass engines, SP3 architecture optimizes performance while delivering comprehensive security.

App-ID Cloud Engine (ACE)in SaaS Security uses cloud-based signatures to detectunknownandunsanctioned SaaS applicationsin the environment.

“App-ID Cloud Engine (ACE) uses real-time cloud intelligence to identify SaaS applications, including previously unknown or newly introduced applications.”

This feature is key for comprehensive SaaS visibility beyond static signatures.

To allow third-party contractors controlled access, security policies must combineuser identificationandtime-based access controls:

User-ID

“User-ID enables security policies to be based on user identity rather than IP addresses, ensuring precise policy enforcement for specific users such as contractors.”

Schedule

“Schedules allow policies to be active only during specific times, providing time-based access control (e.g., after business hours).”

(Source: Security Policy Schedules)

Together, they ensure that only authorized users (contractors) have access, and only when explicitly allowed.

In Prisma Access, theinterzonesecurity policy rule isavailableand plays a crucial role in controlling trafficbetweenzones.

“You can configure an interzone rule to control traffic that flows between different zones in Prisma Access, enabling granular security policy enforcement.”

This ensures comprehensive control of traffic crossing security boundaries in the cloud-delivered architecture.

To connect aremote networkto Prisma Access via Strata Cloud Manager (SCM), the remote network requires anIPSec termination node. This acts as the VPN endpoint, ensuring secure connectivity between branch locations and Prisma Access.

“To onboard a remote network, configure the IPSec termination node on the customer’s premises. This VPN endpoint establishes the secure tunnel to Prisma Access for traffic backhauling.”

Key takeaway:

The IPSec termination node is fundamental for secure, encrypted connectivity.

Host Information Profile (HIP) checksare used in GlobalProtect to collect and evaluate endpoint posture (OS, patch level, AV status) to enforce granular security policies for remote users.

“The HIP feature collects information about the host and can be used in security policies to enforce posture-based access control. This ensures only compliant endpoints can access sensitive resources.”

This enables fine-grained, context-aware access decisions beyond user identity alone.

A security profile group named“default”is automatically applied to all new security rules unless a specific profile group is explicitly configured.

“If a security profile group named ‘default’ exists, it will be automatically applied to any newly created security policy rules to ensure consistent protection.”

This behavior ensures that newly created policies are always protected by default security profiles, minimizing human error.

CASB integration should focus on comprehensive data protection, which includesencryption for data-at-rest and in transit, frequentkey updates, and usingstrong encryption algorithmsto ensure confidentiality and data integrity.

“CASB solutions should enforce encryption for data-at-rest and in transit, implement key rotation policies, and leverage robust encryption algorithms to protect sensitive SaaS application data.”

Enterprise DLPuses cloud analysis to inspect and classify sensitive data innon-file-based formats(e.g., in-line data streams, SaaS communications).

“Enterprise DLP inspects data in non-file-based traffic flows, forwarding suspicious data patterns to the cloud for classification and verdicts.”

(Source: Enterprise DLP Overview)

The other services focus on file-based scanning (WildFire), URL access control (Advanced URL Filtering), or inline SaaS application controls (SaaS Security Inline).

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.
