Cloud-Optimized Firewall Platforms -- Palo Alto Networks Alternatives

Best Cloud Firewall Alternatives to Palo Alto Networks in 2026

Cloud-optimized firewall platforms provide alternatives to Palo Alto's VM-Series and CN-Series for protecting cloud workloads, VPCs, and multi-cloud environments. These alternatives offer native cloud deployment, cloud-specific management, and pricing models optimized for elastic cloud environments where traditional per-appliance licensing creates friction. Organizations moving to cloud-first architectures often find that cloud-optimized firewalls provide faster deployment, simpler operations, and lower costs than extending their on-premises Palo Alto deployment to the cloud.

Our Recommendations

2

Fortinet FortiGate

Hardware appliances from ~$300 (FortiGate 40F) to $100,000+ (FortiGate 7000 series) / FortiGate VM from ~$500/yr / FortiGuard subscription bundles required

FortiGate VM and FortiGate CNF (Cloud-Native Firewall) provide strong NGFW capabilities in cloud form factors at lower per-instance pricing than Palo Alto VM-Series. FortiManager provides unified management across physical and cloud deployments.

3

Juniper SRX

Hardware from ~$1,500 (SRX300) to $150,000+ (SRX5800) / Software licenses for AppSecure, IDP, ATP Cloud sold separately

vSRX virtual firewall is the best option when cloud firewalls need advanced routing capabilities alongside security. Ideal for service providers and enterprises with complex cloud networking requirements where BGP, OSPF, and advanced routing in the cloud are as important as threat prevention.

Cloud-Optimized Firewall Platforms FAQ

Why are Palo Alto VM-Series cloud firewalls so expensive?

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.

Should I use cloud-native firewalls or third-party NGFWs in my cloud?

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.

How do I manage firewalls across multiple clouds?

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.

Is SD-WAN integration important for cloud firewalls?

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.
