For a price-sensitive customer needing to secure a Windows Virtual Server with a maximum throughput of 100Mbps and requiring up to 45,000 sessions, the VM-200 instance is the appropriate choice. The VM-200 is designed to handle up to 100Mbps of throughput and supports a sufficient number of sessions to meet the customer's requirements, making it a cost-effective and suitable option for this use case​ (Palo Alto Networks)​​ (Palo Alto Networks)​.

Palo Alto Networks Single Pass Parallel Processing (SP3) architecture is designed to handle traffic efficiently and securely. The key aspect of SP3 is:

Single Pass Processing (C): This means that all traffic is processed in a single pass through the firewall, regardless of the number of security features enabled. There is no additional performance impact for each feature because the firewall processes all security functions (such as threat prevention, URL filtering, and application control) simultaneously in a single pass. This architecture ensures high performance and low latency while maintaining robust security.

The customer currently lacks visibility into the Layer 7 application traffic on port 53, which is typically used for DNS. Palo Alto Networks' App-ID technology can identify applications traversing the network irrespective of the port, protocol, or encryption (SSL or SSH). By using App-ID, the customer can gain visibility into the specific applications being used, even if they are running over standard ports such as 53. This capability not only identifies the applications but also allows for granular control over them, enabling the customer to block unsanctioned applications if necessary.
