A centralized certificate automation approach reduces management overhead and security risks by standardizing processes, automating renewals, and continuously monitoring the certificate lifecycle.
"Implementing a centralized certificate management approach with automation and continuous monitoring ensures optimal security while reducing operational complexity in hybrid environments." (Source: Best Practices for Certificate Management)

InPalo Alto Networks' Single-Pass Parallel Processing (SP3)architecture, SSL/TLS decryption occurs only during theslow pathwhen the firewall first encounters a new session.
"SSL/TLS decryption, which requires CPU-intensive cryptographic operations, is performed during the slow path when establishing new sessions. Once decrypted, traffic is processed in the fast path for subsequent packets." (Source: Packet Flow and SP3 Architecture) After the initial decryption in the slow path, decrypted traffic is handled by fast path for efficiency.

When usingAWS centralized deploymentsfor Cloud NGFW, the service deploys NGFW instances into selected VPCsas additional workloads to secure that traffic.
"In centralized deployments, Cloud NGFW instances are deployed as security appliances within the selected VPCs, ensuring consistent traffic inspection and protection." (Source: Cloud NGFW Deployment Models) This approach minimizes complexity and ensures direct security policy enforcement within AWS.

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." (Source: Flexible Licensing and Service Subscriptions)

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." (Source: ALG Support)
