Should you use always on VPN?

The Always-On VPN Dilemma: Convenience vs. Compatibility

In today’s hyper-connected world, the security and privacy of data in transit are paramount. For businesses and individuals alike, Virtual Private Networks (VPNs) have become a crucial tool for protecting sensitive information when accessing the internet from potentially insecure networks. Among the various VPN implementations, the “Always On VPN” approach is gaining traction, but is it always the right choice?

The core concept of an Always On VPN is simple: a continuous, automatic VPN connection that activates as soon as the device powers on. This eliminates the need for manual connection procedures, ensuring a constant layer of protection without user intervention. Microsoft itself champions Always On VPN, even suggesting it as a preferred alternative to its older DirectAccess technology, particularly when implementing new VPN solutions. The allure of seamless security is undeniable.

However, the decision to embrace Always On VPN is not without its considerations. The technology, while powerful, isn’t a universal panacea. Here’s a breakdown of the benefits and drawbacks:

The Upsides: Uninterrupted Protection and Streamlined Security

• Persistent Security: The primary advantage is continuous protection. An Always On VPN ensures that all internet traffic is encrypted and routed through a secure tunnel, minimizing the risk of data interception or exposure on public Wi-Fi networks. This is especially vital for remote workers handling sensitive company data.
• Simplified User Experience: Users don’t need to remember to connect manually or troubleshoot connection issues. The VPN operates silently in the background, freeing them to focus on their work.
• Centralized Management and Control: Always On VPNs are often paired with robust management tools, allowing administrators to enforce security policies, control access to resources, and monitor network activity across the entire organization.
• Improved Compliance: For businesses subject to strict data privacy regulations like GDPR or HIPAA, an Always On VPN can be a valuable asset in demonstrating compliance and protecting sensitive customer information.

The Downsides: Compatibility and Performance Considerations

• Operating System Limitations: This is a crucial caveat. Always On VPNs are primarily designed for modern operating systems. As Microsoft itself highlights, Always On VPN inherently requires Windows 10 or later. This creates a significant barrier for organizations reliant on older Windows versions or a mix of operating systems, including macOS, Linux, or mobile platforms. Upgrading an entire infrastructure can be a costly and time-consuming endeavor.
• Performance Overhead: All VPNs introduce some degree of performance overhead. The encryption and routing processes can impact internet speed and battery life, especially on mobile devices. While modern VPN protocols are optimized for efficiency, the impact can still be noticeable, particularly on bandwidth-intensive applications.
• Compatibility Issues: While increasingly rare, some applications and services may encounter compatibility issues with certain VPN configurations. This might require adjustments to VPN settings or alternative solutions to ensure proper functionality.
• Increased Complexity: While the end-user experience is simplified, the initial configuration and maintenance of an Always On VPN can be complex, requiring specialized expertise.
• Dependency and Single Point of Failure: Relying solely on an Always On VPN can create a single point of failure. If the VPN server or connection experiences issues, users may be unable to access the internet or critical resources, potentially disrupting operations.

The Verdict: Context is Key

Ultimately, the decision of whether or not to embrace an Always On VPN hinges on a careful assessment of your specific needs, environment, and risk tolerance.

• If your organization primarily uses Windows 10 (or later) and prioritizes seamless, persistent security for remote workers, an Always On VPN is a strong contender. The benefits of simplified user experience and centralized management often outweigh the potential drawbacks.

• However, if you have a mixed environment with older Windows versions or non-Windows devices, the compatibility limitations of Always On VPN may be a deal-breaker. In such cases, a more flexible VPN solution that supports a wider range of platforms might be a better fit.

• Consider alternative VPN solutions if performance overhead is a major concern, or if you require granular control over which applications and services are routed through the VPN.

Before deploying an Always On VPN, it’s crucial to conduct thorough testing to identify and address any potential compatibility or performance issues. A pilot program with a small group of users can provide valuable insights and help refine the configuration.

In conclusion, Always On VPN offers compelling advantages in terms of security and user convenience. However, it’s not a one-size-fits-all solution. By carefully weighing the benefits and drawbacks, and considering the specific needs of your organization, you can make an informed decision that aligns with your security goals and operational requirements. Don’t be swayed by the buzz; evaluate thoroughly before committing to an Always On VPN deployment.
