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. 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.

Why Cloud Workloads Need Dedicated Firewall Protection

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 firewalls fill that gap with full NGFW capabilities running as cloud-native instances. You get SSL/TLS inspection, anti-malware, web filtering, and IPS directly in your cloud VPC—not bolted on after the fact.

Cloud environments also introduce unique risks. Misconfigured security groups, overly permissive IAM policies, and east-west traffic between cloud services create attack surfaces that perimeter-only security cannot address. FortiGate virtual appliances inspect traffic between subnets, between VPCs, and between cloud and on-premises networks, providing the segmentation and visibility that cloud-native tools alone cannot deliver.

AWS and Azure Deployment Models

FortiGate virtual firewalls are available as marketplace images on both AWS and Azure, supporting deployment patterns that match your architecture. Common configurations include:

Transit VPC / Virtual WAN hub — Centralized inspection point for all inter-VPC and internet-bound traffic, reducing policy sprawl across accounts and subscriptions
Inline NGFW — Deployed within a VPC as the default gateway for workload subnets, providing north-south and east-west inspection
VPN concentrator — Terminating site-to-site and remote access VPN tunnels in the cloud, connecting branch offices and remote workers to cloud resources securely
Auto-scaling clusters — FortiGate instances that scale horizontally based on traffic load, managed through FortiManager for consistent policy across all instances

Infonaligy handles the full deployment lifecycle: architecture design, infrastructure-as-code templates (Terraform, CloudFormation), initial configuration, and ongoing management. We ensure FortiGate virtual appliances integrate correctly with cloud load balancers, route tables, and availability zones so you get high availability without manual intervention.

Hybrid Cloud Security Architecture

Most organizations operate hybrid environments where workloads span on-premises data centers and one or more cloud providers. FortiGate unifies security policy across these environments through FortiManager centralized management. A single policy framework governs traffic inspection whether the workload runs on a FortiGate data center appliance or a cloud virtual instance.

This consistency eliminates the security gaps that emerge when separate teams manage cloud and on-premises firewalls with different tools and different rule sets. Infonaligy designs hybrid architectures where FortiGate SD-WAN connects your sites to cloud workloads over encrypted tunnels, with consistent threat inspection at every transit point.

Cloud Workload Protection and Microsegmentation

FortiGate virtual firewalls enable microsegmentation within cloud environments, restricting lateral movement between application tiers, development and production environments, and multi-tenant workloads. If an attacker compromises a web server, microsegmentation policies prevent that compromise from reaching database tiers or adjacent applications.

Combined with FortiGate’s integration into the Fortinet Security Fabric, cloud deployments benefit from shared threat intelligence, automated response workflows, and centralized logging through FortiAnalyzer. This fabric-level integration means a threat detected on a branch office FortiGate firewall automatically updates protection across your cloud instances.

Auto-Scaling and Performance Optimization

Cloud workloads are dynamic. Traffic patterns shift based on business cycles, marketing campaigns, or seasonal demand. FortiGate cloud deployments support auto-scaling groups that add or remove firewall instances based on throughput, connection count, or CPU utilization. FortiManager synchronizes configuration to new instances automatically, ensuring every scaled instance enforces identical security policy.

Infonaligy monitors FortiGate cloud performance through FortiAnalyzer and our own managed security operations, identifying capacity thresholds before they impact application performance. We right-size instance types based on actual traffic analysis rather than vendor sizing guides, keeping cloud security costs aligned with actual utilization.

Cost Management for Cloud Security

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 traffic 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.

Centralized Management and Visibility

FortiManager provides a single console for managing FortiGate policies across cloud, data center, and branch deployments. FortiAnalyzer aggregates logs and generates compliance reports regardless of where the firewall instance runs. This centralized visibility is essential for organizations operating under compliance frameworks like HIPAA, PCI DSS, or CMMC, where demonstrating consistent security controls across all environments is a regulatory requirement.

Infonaligy manages this infrastructure on your behalf, providing monthly security posture reports, policy change management, and 24/7 monitoring of your cloud firewall fleet.
