FortiGate Cloud & Virtual Firewall Solutions
Moving workloads to the cloud does not eliminate the need for next-generation firewall protection — it changes where and how that protection must be delivered. Native cloud security groups and network ACLs provide basic traffic filtering, but they lack the application-layer visibility, threat intelligence, and unified policy management that modern enterprises require.
FortiGate virtual appliances extend the same deep packet inspection, intrusion prevention, and application control you rely on in your physical data center to AWS, Azure, and hybrid cloud environments. As a certified Fortinet partner, Infonaligy designs and manages FortiGate cloud deployments that protect your workloads without sacrificing the agility that drove your cloud migration.
FortiGate Cloud Firewall at a Glance

→ Get a clear view of your cloud security posture before misconfigurations or protection gaps create risk.
Does Your Cloud Environment Need a Virtual Firewall?
Cloud environments introduce risks that perimeter-only security cannot address. Misconfigured security groups, overly permissive IAM policies, and unmonitored east-west traffic between cloud services create attack surfaces that native tools miss.
You may need a FortiGate cloud firewall if:
- ✓You run production workloads in AWS, Azure, or both.
- ✓Native security groups lack the application-layer visibility you need.
- ✓Your cloud and on-premises firewalls are managed with different tools and different rule sets.
- ✓East-west traffic between cloud subnets or VPCs is not inspected.
- ✓You handle regulated data (HIPAA, PCI DSS, CMMC) in cloud environments.
- ✓Traffic patterns shift seasonally and you need firewall capacity that scales with demand.
- ✓Remote workers and branch offices connect to cloud resources over VPN.
- ✓Your team lacks the bandwidth to manage cloud firewall policy alongside everything else.
→ If any of these apply, let Infonaligy assess your cloud security architecture and identify the gaps that need attention.
AWS & Azure Deployment Models
FortiGate virtual firewalls are available as marketplace images on both AWS and Azure, supporting deployment patterns that match your architecture.
Transit VPC / Virtual WAN Hub
Centralized inspection point for all inter-VPC and internet-bound traffic. Reduces policy sprawl across accounts and subscriptions by routing all traffic through a single managed firewall cluster.
Inline NGFW Gateway
Deployed within a VPC as the default gateway for workload subnets. Provides north-south and east-west inspection for traffic entering, leaving, and moving between application tiers.
Cloud VPN Concentrator
Terminates site-to-site and remote access VPN tunnels in the cloud. Connects branch offices and remote workers to cloud resources securely with encrypted tunnels and consistent policy enforcement.
Auto-Scaling Firewall Clusters
FortiGate instances that scale horizontally based on traffic load, connection count, or CPU utilization. FortiManager synchronizes configuration to every new instance automatically.
Infonaligy handles the full deployment lifecycle — architecture design, infrastructure-as-code templates (Terraform, CloudFormation), initial configuration, integration with cloud load balancers and availability zones, and ongoing management.

Traffic analysis, instance right-sizing, and licensing model recommendations (PAYG vs. BYOL) to minimize total cost of ownership.
→ Work with a certified Fortinet partner that handles the full deployment lifecycle — not just the initial setup.
How We Deploy FortiGate Cloud Firewalls
Assess Your Cloud Environment
We review your current cloud architecture, security group configurations, traffic flows, compliance requirements, and existing firewall infrastructure to identify protection gaps.
Design the Architecture
We design a FortiGate deployment model — transit hub, inline gateway, VPN concentrator, or a combination — based on your workloads, traffic patterns, and hybrid connectivity needs.
Deploy & Configure
We provision FortiGate instances using infrastructure-as-code, configure security policies, integrate with cloud load balancers and route tables, and validate high availability.
Connect & Unify
We connect cloud firewalls to your on-premises FortiGate appliances through FortiManager, establishing a single policy framework that governs traffic inspection everywhere.
Monitor, Optimize & Report
We provide ongoing monitoring, performance optimization, auto-scaling management, compliance reporting, and monthly security posture reviews — so cloud security stays ahead of your workloads.
→ Start with a cloud security architecture review — we will assess your environment and design the right deployment.
Cloud Firewall Cost Management
Cloud firewall licensing follows either a pay-as-you-go model (hourly marketplace billing) or bring-your-own-license (BYOL) with Fortinet contracts. Each model has cost implications depending on your usage patterns.
Infonaligy analyzes your traffic volumes, instance uptime, and scaling requirements to recommend the licensing model that minimizes total cost of ownership. We also optimize cloud architecture to reduce unnecessary inspection costs — ensuring that intra-subnet traffic between trusted workloads does not route through firewall instances unnecessarily, while maintaining full inspection for traffic that crosses trust boundaries.
| Licensing Model | Best For | How It Works |
|---|---|---|
| Pay-As-You-Go (PAYG) | Variable workloads, dev/test environments, short-term projects | Hourly billing through the AWS or Azure marketplace — no upfront commitment |
| Bring Your Own License (BYOL) | Steady-state production, predictable traffic, multi-year deployments | Fortinet contract licenses applied to cloud instances — lower per-hour cost at committed volumes |
→ Let Infonaligy analyze your cloud traffic and recommend the licensing model that keeps costs aligned with actual utilization.

Frequently Asked Questions About FortiGate Cloud Firewalls
A FortiGate virtual firewall is a software-based next-generation firewall that runs as a virtual appliance in cloud environments like AWS and Azure. It provides the same deep packet inspection, intrusion prevention, and application control as a physical FortiGate appliance.
Native cloud security groups filter traffic at the network layer but lack application-layer visibility, threat intelligence, SSL/TLS inspection, and unified policy management. FortiGate virtual firewalls fill that gap with full NGFW capabilities running directly in your cloud VPC.
Yes. FortiGate virtual firewalls are available as marketplace images on both AWS and Azure, supporting transit VPC, inline NGFW, VPN concentrator, and auto-scaling deployment patterns on either platform.
Yes. FortiManager provides centralized management across cloud, data center, and branch FortiGate deployments. A single policy framework governs traffic inspection whether the workload runs on a physical appliance or a cloud virtual instance.
FortiGate cloud deployments support auto-scaling groups that add or remove firewall instances based on throughput, connection count, or CPU utilization. FortiManager automatically synchronizes configuration to new instances so every scaled instance enforces identical security policy.
FortiGate cloud firewalls support pay-as-you-go (hourly marketplace billing) and bring-your-own-license (BYOL) with Fortinet contracts. Infonaligy analyzes your traffic patterns and usage to recommend the model that minimizes total cost of ownership.
