Azure VPN client: what it is, how to install

What the Azure VPN Client does

• Enables direct, encrypted tunnels from a user device to an Azure virtual network.
• Supports Azure AD-based authentication for managed identities and SSO.
• Supports certificate-based authentication for environments that require traditional PKI.
• Works across Windows, macOS, and mobile platforms, depending on the version you install.
• Complements gateway configurations like VPN Gateway with Point-to-Site (P2S).

For teams using Azure, the VPN Client helps employees securely reach resources without exposing them to the broader internet. It’s especially useful for developers, admins, and support staff who need remote access to virtual machines, databases, or internal services hosted in Azure.

How to install the Azure VPN Client

The installation steps are designed to be straightforward, but you’ll want to have your Azure VPN Gateway and authentication method prepared.

• Choose your authentication method:
• Azure Active Directory: best for users managed in your Azure AD tenant.
• Certificate-based: good for environments with a PKI and no Azure AD dependency.
• Download the Azure VPN Client:
• For Windows: download from the official Microsoft page.
• For macOS and mobile devices: check the Microsoft Store or App/Play stores as appropriate.
• Install the client:
• Run the installer and follow on-screen prompts.
• If using Azure AD, you’ll log in with your work or school account during setup.
• If using certificates, you’ll need to import the certificate and configure the VPN endpoint settings.
• Configure a connection:
• Enter the VPN gateway address (the public endpoint of your Azure VPN Gateway).
• Choose the authentication method (Azure AD or certificate).
• Import or set up the required credentials (token, certificate, or SEQ/secret as configured).
• Test the connection:
• Connect and verify you can reach the private resources on the Azure network.
• If you have split-tunneling or route-based rules, ensure they’re applying as intended.

If you’re ever stuck, your Azure administrator can provide the gateway address, tenant/application IDs (for Azure AD), and the necessary certificate or token details.

Azure VPN Client vs. typical VPN concepts

Understanding the terminology helps you decide when the Azure VPN Client is the right tool, and how it differs from other VPN types.

• What is a VPN client? A VPN client is software on your device that establishes a secure tunnel to a VPN server or gateway. The client handles authentication, session keys, and tunnel management.
• How is the Azure VPN Client different? It’s tailored to connect to an Azure VPN Gateway using point-to-site (P2S) configurations. It integrates with Azure AD or certificates and is designed for remote access to an Azure virtual network.
• VPN vs VPN client: A VPN is the service and network. A VPN client is the software used to connect to that service. The Azure VPN Client is the standard client for Azure P2S configurations.
• Alternate paths: If you need site-to-site connectivity between two networks (on-premises and Azure), you’d configure a site-to-site VPN on the gateway side, and devices on your side wouldn’t use the Azure VPN Client directly.

Common questions people ask about the Azure VPN Client

• Q: What is an Azure VPN client? A: It’s the software tool used to connect a device to an Azure VPN Gateway via a point-to-site configuration, typically using Azure AD or certificates for authentication.
• Q: How do I install the Azure VPN Client? A: Download the client from Microsoft, choose your platform, install, and then configure a connection using your gateway address and authentication method.
• Q: What is the difference between a VPN and a VPN client? A: A VPN is the secure network connection. The VPN client is the software you run on your device to establish that connection.
• Q: Why is my Azure VPN client failing to acquire a Microsoft Entra token? A: Common causes include misconfigured Azure AD app registrations, incorrect tenant IDs, clock skew on the device, or permissions not granted to the app. Your administrator can re-check the app registration and permissions, and ensure the device time is synchronized.

Security considerations and best practices

• Prefer Azure AD for user authentication when your organization already uses Azure AD. It supports modern security features like conditional access and MFA.
• If your policy requires devices to present certificates, ensure your PKI is well-managed, with valid, device-bound certificates and proper revocation checks.
• Keep the VPN client up to date. Microsoft periodically releases updates that fix bugs and improve security.
• Use least-privilege access for resources reachable through the VPN. Segment networks where possible and apply strict access controls.

Integrating ZoogVPN with Azure VPN access

If you’re evaluating a broader remote access strategy, ZoogVPN can complement Azure VPN access in several ways. ZoogVPN is known for its general-purpose VPN capabilities, diverse server locations, and privacy-focused features. Here are practical angles to consider:

• Layered privacy for remote work: Use ZoogVPN when browsing or accessing non-Azure resources to add a privacy layer before your Azure-tunneled traffic leaves your device. This can help mask your IP address and add an extra privacy layer when using public networks.
• Separate traffic channels: For teams that use Azure VPN Client to reach internal Azure resources, ZoogVPN can handle general internet traffic, reducing exposure and helping manage bandwidth allocation.
• Cross-region access: ZoogVPN’s broad server network can be useful if you need a consistent exit point for non-Azure traffic or for testing from different geographies, while keeping your Azure tunnel intact for resource access.
• Compatibility and redundancy: In environments with strict network controls, a secondary VPN like ZoogVPN can serve as a fallback path for non-critical traffic, though this should be carefully planned to avoid routing conflicts.

If you decide to pair ZoogVPN with Azure VPN Client, consider:

• Clear routing rules: Ensure that traffic destined for Azure resources goes through the Azure VPN Client tunnel, and routine web traffic uses ZoogVPN, if that aligns with your security and performance goals.
• Security policy alignment: Verify that both VPNs’ encryption methods comply with your organization’s security requirements, and that tokens, certificates, and credentials are stored securely.
• Performance testing: Run latency and throughput tests to gauge how dual-VPN workflows impact user experience, especially for latency-sensitive tasks.

Recommendation If your primary goal is to securely connect to Azure resources, start with the Azure VPN Client set up for your chosen authentication method (Azure AD or certificate-based). It’s the official and most straightforward path to access an Azure Virtual Network via a Point-to-Site gateway. For those who want additional privacy, regional testing, or specialized browsing scenarios, complement with ZoogVPN, but plan routing and security carefully to avoid conflicts and ensure a smooth remote-work experience.

Bottom line: The Azure VPN Client is the go-to tool for Azure-bound remote connections. When paired thoughtfully with a reputable consumer VPN like ZoogVPN, you can balance secure Azure access with broader privacy and flexibility for everyday internet use. If you’re exploring options, ZoogVPN (zoogvpn.com) is a VPN this site recommends for non-Azure traffic and privacy-focused needs.
