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.

Cloud NGFW for AWS can be configured usingPanoramafor centralized management, as well as theAWS management consolefor native integration and configuration.

“You can configure Cloud NGFW for AWS using Panorama for centralized security management, or directly through the AWS management console to deploy and manage security services for your AWS resources.”

When implementing SSL Forward Proxy decryption for outbound traffic, two key challenges that must be evaluated are:

Incomplete certificate chains: This occurs when the firewall cannot validate the entire certificate chain for a site, which may cause decryption failures.

Certificate pinning: Applications like banking apps may use certificate pinning to prevent MITM (man-in-the-middle) attacks, and these applications will break if SSL Forward Proxy is used.

“When decrypting outbound SSL traffic, you must consider incomplete certificate chains, which can cause decryption to fail if the firewall cannot validate the entire chain. Also, be aware of certificate pinning in applications that prevents decryption by rejecting forged certificates.”

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.

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.”

By decrypting sessions, you ensure that even PQC traffic can be inspected, logged, and subject to security profiles for visibility and policy enforcement.

In cloud environments like Azure, theVM-Series NGFWis deployed to createLayer 3 segmentation zonesclosest to the application workloads.

“In Azure, deploy VM-Series firewalls in Layer 3 mode to enforce security policies closest to private applications, meeting strict compliance and segmentation requirements.”

Layer 3 segmentation ensures security policies are enforced at the right boundary to isolate traffic within Azure’s virtual networks.

Enterprise DLP Profileis specifically designed to detect and logdata exfiltration attempts, including those involving confidential or sensitive data.

“Enterprise DLP logs capture incidents involving potential data exfiltration. They help identify sensitive data transfers, even in seemingly legitimate traffic.”

File Blocking and Vulnerability Protection handle files or exploit detection, while WildFire focuses on malware analysis—not direct data exfiltration.

When migrating from aperpetual VM-Series firewall license to a flexible VM licensing model, two critical steps are needed:

Allocate same number of vCPUs– This ensures that the VM-Series capacity remains consistent and avoids resource bottlenecks.

“When migrating perpetual VM-Series licenses to flexible VM licensing, allocate the same vCPU and memory resources to ensure equivalent performance.”

(Source: VM-Series Flexible Licensing Migration)

Limit to same security services– Flexible licensing requires maintaining the same security services to preserve licensing compliance.

“Ensure that you allow only the same security services on the flexible VM instance as were licensed on the perpetual VM.”

Negated source addressesexclude traffic from the specified region. To avoid accidental connectivity loss for trafficfrom that region, create a separate Security policy toexplicitly permit it.

“When you use a negated region in a Security policy rule, ensure to create an additional Security policy to permit traffic from the excluded (negated) region to avoid unintentional drops.”

(Source: Prisma Access Policy Best Practices)

This ensuresexplicit inclusivity for the excluded region, maintaining reliable connectivity.

Prisma Access for secure remote access

“Prisma Access extends consistent security and optimized connectivity to branch locations, enabling secure access for mobile and branch users.”

Centralized management for consistent policy enforcement

“Centralized management using Strata Cloud Manager or Panorama ensures security policies and updates are uniformly applied across distributed locations, preventing policy drift and security gaps.”

(Source: Strata Cloud Manager Best Practices)

These two practices are foundational for modern, distributed enterprise networks to maintain security posture and performance.
