HYBRID NETWORKING

Extend Your Network Securely to Azure with Palo Alto VPN

Executive Summary

As organizations modernize workloads in Azure, secure hybrid connectivity becomes essential.
Deop helps clients integrate Palo Alto Networks firewalls with Azure VPN Gateway to create encrypted, policy-driven connections between on-premises data centers and the cloud.

The result is a seamless, compliant, and high-performance hybrid network that maintains centralized visibility, governance, and zero-trust control across environments.

The Challenge

Hybrid networks often face:

  • Fragmented security policies across on-prem and cloud.
  • Inconsistent VPN tunnel configurations.
  • Manual routing or static IP dependencies.
  • Limited visibility into encrypted traffic and compliance reporting.

These gaps expose organizations to unnecessary risk and operational complexity.

Deop resolves them through unified design, automation, and policy consistency between existing Palo Alto deployments and Azure.

Deop’s Solution: Palo Alto + Azure VPN Integration

Deop architects and deploys IPSec-based VPN tunnels that securely bridge on-premises networks to Azure VNets using Palo Alto firewalls and Azure VPN Gateway.

Architecture Overview:

On-Prem Firewall (Palo Alto): Initiates and manages IPSec VPN tunnels with encryption, authentication, and logging.

Azure VPN Gateway: Terminates the tunnels, supporting BGP dynamic routing for resilient connectivity.

Azure Virtual Network (VNet): Hosts workloads with private address space and segmentation controls.

Automation: Terraform and Azure DevOps pipelines or GitHub Actions manage VPN provisioning, routing updates, and HA configuration.

Security & Compliance

Deop’s architecture ensures:

  • End-to-end encryption of all traffic between sites.
  • Role-based access control (RBAC) via Azure AD integration.
  • Continuous monitoring and alerts through centralized logging.
  • Compliance alignment with PIPEDA, PBMM, and ISO 27001.
  • Audit-ready reporting for security and network events.

This enables IT and compliance teams to confidently extend critical workloads into Azure without compromising sovereignty or governance.

Implementation Approach

Deop follows a proven 4-phase integration model:

  • Assessment & Design – Analyze existing firewall policies, identify subnets, and plan tunnel topology.
  • Configuration & Deployment – Deploy IPSec tunnels using Terraform, configure BGP routing, and verify connectivity.
  • Automation & Observability – Implement Azure Monitor and Palo Alto Panorama integration for health and traffic insights.
  • Validation & Handover – Conduct HA and failover testing, document configurations, and enable client self-service for future scaling.

Each implementation is automated through infrastructure-as-code (IaC) and CI/CD pipelines to ensure repeatability and compliance consistency.

FAQ

Benefits:

- Seamless Hybrid Connectivity: Unified, encrypted connection between on-prem and Azure workloads.
- Improved Security Posture: Centralized policies via Palo Alto and Azure Firewall Manager.
- Operational Efficiency: Automated configuration and health checks through DevOps pipelines.
- Regulatory Compliance: Traffic remains within Canadian regions (Canada East/Central).
- High Availability: Redundant tunnels with automatic BGP failover.

Can this design support multiple Azure regions?

Yes. We use dynamic BGP routing to automatically manage multiple regional connections.

Does this align with zero-trust principles?

Yes. The design enforces least-privilege access, micro-segmentation, and continuous traffic inspection across all network boundaries.

Is ExpressRoute required for this setup?

No. IPSec VPN with BGP is fully supported and ideal for SMB or public-sector use cases; ExpressRoute can be added later for higher throughput.

How does Deop keep VPN compliant?

Deop automates VPN configurations through Terraform and CI/CD pipelines, ensuring every change meets Azure and Palo Alto security policies.

Q: How do we monitor VPN health?

Deop integrates Azure Monitor, Palo Alto Panorama, and alerting pipelines for real-time visibility and SLA tracking.

Can I use other firewalls with this setup?

Yes. Deop supports multi-vendor IPSec and BGP integration, allowing Palo Alto to work alongside Fortinet, Cisco, or existing firewalls.
