Importance of Security in Remote Access
Before we dive into VMware UAG’s features and deployment, let’s underscore the critical importance of security in remote access solutions. In today’s interconnected world, where sensitive corporate data is accessed from various devices and locations, maintaining the highest level of security is non-negotiable. Here are some reasons why security is paramount in remote access solutions:
- Data Protection – Remote access solutions deal with sensitive data, intellectual property, and confidential information. A breach could lead to data leaks, financial losses, and reputation damage.
- Compliance – Many industries have strict compliance requirements (e.g., HIPAA, GDPR) that mandate data protection measures. Failing to comply with these regulations can result in legal penalties.
- Cyber Threats – The cyber threat landscape is constantly evolving. Attackers are constantly devising new tactics to infiltrate networks and steal data. A robust security framework is necessary to defend against these threats.
- User Authentication – Ensuring that only authorized users gain access to corporate resources is a fundamental aspect of security. Strong authentication mechanisms are crucial.
- Endpoint Security – As users access corporate resources from various devices, ensuring the security of these endpoints is vital. Malware-infected devices can become entry points for attackers.
VMware Unified Access Gateway (UAG) – An Overview
VMware Unified Access Gateway is a critical component of VMware’s Digital Workspace platform. It is designed to provide secure remote access to corporate resources for a wide range of devices, including PCs, Macs, smartphones, and tablets.
Unified Access Gateway is a VMware hardened Linux based virtual security appliance designed to protect remote user access to end-user computing resources such as virtual desktops and applications. It is designed to operate with the following VMware solutions:
- Desktop and App Virtualization with Horizon 7/8 and Horizon Cloud
- Workspace ONE Access
- Workspace ONE UEM
- Per-App Tunnel
- Content Gateway
- Secure Email Gateway

UAG offers several key features that make it an attractive choice for organizations looking to bolster their remote access capabilities:
- Single Sign-On (SSO): UAG enables users to access multiple applications and resources with a single set of credentials. This enhances user experience while maintaining security.
- Per-App Tunneling: UAG allows organizations to control access to specific applications, rather than providing unfettered access to the entire network. This helps in limiting potential attack vectors.
- Device Compliance Checking: Administrators can enforce policies to ensure that only compliant and secure devices can access corporate resources.
- Load Balancing and High Availability: UAG supports load balancing for high traffic environments and offers high availability options to ensure uninterrupted access.
Unified Access Gateway distributed as a single file (OVF) that is pre-hardened and tested overall by VMware. All configuration settings can be pushed during deployment so that Unified Access Gateway is “production-ready on first boot” and using automated deployment, and take less than 2 minutes. There is no need to separately configure or harden the appliance after it is deployed.
Depending on the architecture you’re targeting, you can deploy it within vSphere or ESXi environments, Amazon AWS EC2, Microsoft Azure, Hyper-V or Google Compute Engine (GCE).
Deploying VMware Unified Access Gateway can be a complex task, but VMware has provided comprehensive documentation and resources to guide administrators through the process. Here is an overview of the deployment steps:
- Ensure that you have a VMware vSphere environment set up.
- UAG needs DNS configuration for the appliance, and netmask, default gateway, and subnet to be defined, for each network that is enabled during deployment.
- Get the UAG OVA (Open Virtualization Appliance) file from VMware’s official website.
2. Installation and Configuration:
- Deploy the UAG appliance using the OVA file in your vSphere environment.
- Configure the network settings, including IP address, subnet mask, and DNS settings.
- Access the UAG configuration interface through a web browser and perform the initial setup.
Note: There is a great tool that is available as a VMware Fling called the Unified Access Gateway Appliance Installer. You can check out the details here:

- Configure Single Sign-On (SSO) to streamline the login process.
4. Application Configuration:
- Define the applications and resources that users will access through UAG.
- Configure per-app tunneling rules to control access to specific resources.
5. Security Configuration:
- Implement multi-factor authentication (MFA) to enhance security.
- Set up endpoint compliance checks to ensure device security.
6. Load Balancing and High Availability:
- Implement load balancing if your environment requires it.
- Set up high availability to ensure continuous access in case of appliance failures.
7. Testing and Monitoring:
