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.

The“Report and Maintenance”step of the Zero Trust model emphasizes ongoing monitoring, analysis, and reporting to ensure the environment remains secure over time.

“The Report and Maintenance phase includes continuous monitoring, log forwarding, and sharing of security telemetry to third-party tools to maintain and validate Zero Trust implementation.”

By forwarding logs to SOC tools, the engineer ensures comprehensive visibility and proactive threat hunting.

TheVM-Series NGFWsare designed to integrate seamlessly with bothPanoramaandStrata Cloud Manager(SCM), allowing administrators to managephysical and virtualfirewall deployments from either interface.

“You can manage VM-Series Next-Generation Firewalls using either Panorama for centralized management of all firewalls or Strata Cloud Manager for cloud-based management, giving flexibility across hybrid environments.”

(Source: VM-Series Management Options)

Unified management flexibility is key for enterprises with hybrid or multi-cloud deployments.

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.”

Dynamic path selectionis the foundation of SD-WAN, leveraging real-time performance data to dynamically route traffic over the best available path.

“Dynamic path selection continuously monitors performance metrics (loss, latency, jitter) and makes real-time routing decisions to ensure application SLAs are met across the WAN.”

(Source: Prisma SD-WAN Dynamic Path Selection)

Establishing dynamic path selection first ensures the rest of the SD-WAN optimizations (e.g., failover, QoS) work effectively.

Blocking non-compliant SSH versionsandfailing certificate validationsare fundamental security measures:

Block sessions when certificate validation fails

“The SSH Proxy profile should block sessions that fail certificate validation to ensure that only trusted hosts are allowed.”

(Source: SSH Proxy Decryption Best Practices)

Block connections using non-compliant SSH versions

Older SSH versions may have vulnerabilities or lack modern encryption algorithms.

“To enforce stronger security, block SSH sessions that use older or deprecated versions of the SSH protocol that do not comply with your security posture.”

(Source: SSH Decryption and Best Practices)

Together, these measuresminimize the risk of MITM attacksand secure SSH traffic.

Advanced WildFiresupports direct integrations into third-party security tools through theWildFire API, enabling automated threat intelligence sharing and real-time verdict dissemination.

“WildFire exposes a RESTful API that third-party applications can leverage to integrate WildFire’s analysis results and threat intelligence seamlessly into their own security workflows.”

(Source: WildFire API Guide)

The API provides:

Verdict retrieval

Sample submission

Report retrieval

“Use the WildFire API to submit samples, retrieve verdicts, and obtain detailed analysis reports for integration with your existing security infrastructure.”

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.”

(Source: ACE for SaaS Visibility)

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

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.”

(Source: Security Profile Groups)

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

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.”

(Source: SP3 Architecture)

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

Palo Alto Networks'Enterprise DLPuses a centralized DLP profile that can be applied consistently across both Prisma Access and NGFWs using Strata Cloud Manager (SCM). This eliminates the need for duplicating efforts across multiple locations.

“Enterprise DLP profiles are created and managed centrally through the Cloud Management Interface and can be used seamlessly across NGFW and Prisma Access deployments.”

Dynamic analysisin WildFire refers to executing unknown files in a controlled environment (sandbox) to observe their real-world behavior. This allows the firewall to detect zero-day threats and advanced malware by directly analyzing the file’s impact on a system.

“WildFire dynamic analysis detonates unknown files in a secure sandbox environment, analyzing real-world effects, behaviors, and potential malicious activity.”

An ALG is designed toinspect and modify the payloadof application-layer protocols (like SIP, FTP, etc.) to manage dynamic port allocations and session information.

“Application Layer Gateways (ALGs) inspect the payload of certain protocols to dynamically manage sessions that use dynamic port assignments. By modifying payloads, the ALG ensures that NAT and security policies are correctly applied.”
