Frequently Asked Questions

Palo Alto VM-Series pricing reflects the full PAN-OS feature set including App-ID, WildFire, Threat Prevention, and URL Filtering running in a virtual form factor. Each VM-Series instance requires its own license plus subscription add-ons, which can cost $5,000-25,000+ per instance per year depending on the tier. In elastic cloud environments where you may need dozens of instances, this cost structure becomes prohibitive. Alternatives like Barracuda CloudGen (from ~$1/hr) and FortiGate VM offer comparable cloud security at significantly lower per-instance costs.

Cloud-native firewalls (AWS Network Firewall, Azure Firewall, GCP Cloud Firewall) provide basic L3/L4 stateful inspection and are sufficient for many workloads. Third-party NGFWs like Palo Alto VM-Series, FortiGate VM, or Barracuda CloudGen add L7 inspection, application identification, IPS, and advanced threat prevention. Use cloud-native firewalls for standard VPC security and traffic control. Use third-party NGFWs when you need application-level visibility, threat prevention, or consistent security policy across multi-cloud and hybrid environments.

Multi-cloud firewall management requires a centralized management platform that supports all your cloud environments. Palo Alto Panorama, Fortinet FortiManager, and Barracuda Firewall Control Center all provide cross-cloud management from a single console. The key is ensuring your management platform can deploy, configure, and monitor firewall instances across AWS, Azure, and GCP consistently. Barracuda and Fortinet have the advantage of native cloud marketplace deployment combined with centralized management at lower per-instance costs than Palo Alto.

For organizations with distributed branch offices connecting to cloud workloads, integrated SD-WAN in the cloud firewall significantly simplifies architecture. FortiGate and Barracuda CloudGen both include SD-WAN natively, enabling application-aware routing between branches and cloud resources through a single platform. Palo Alto requires Prisma SD-WAN as a separate product with separate licensing. If your architecture involves branch-to-cloud connectivity, integrated SD-WAN can reduce complexity and cost.
