6.1 What Are The Limitations of Traditional Remote Access VPN Architectures?
Remote work persists. But there’s a problem. Architecturally, remote access VPN is a hub-and-spoke architecture, with users sitting in spokes of various lengths depending on their distance from the hub (the internal data center). The distance reduces performance and introduces latency problems, but this remains the optimal architecture for data center applications because the goal is to reach the hub.
Despite their widespread use, traditional remote access VPN architectures have limitations. The hub-and-spoke model can lead to performance bottlenecks and latency issues, especially for users who are geographically distant from the central hub. Additionally, routing all traffic through the corporate network can create inefficiencies and strain network resources. These limitations have led to the development of alternative solutions that are better suited for the modern, cloud-centric work environment.
6.2 How Are Organizations Compensating for Networking Difficulties With Remote Access VPN?
The model breaks down when there are cloud applications in the environment. Traffic in a remote access VPN always goes to the VPN gateway first, even if the application is hosted in the cloud. As a result, the traffic goes to the VPN gateway at headquarters, then egresses from the corporate perimeter firewall to the internet, with the application response going back to headquarters before it returns to the user.
Although this is reasonable from a security perspective, it doesn’t make sense for network optimization. To compensate for the networking difficulties with remote access VPN, organizations often make compromises that have negative security implications, including user-initiated tunnels, split-tunnel VPN, and web proxies. The need for a more efficient and secure solution has driven the development of modern architectures that are optimized for cloud-based applications.
6.3 What Are Modern Architectures for The Mobile Workforce?
With the rapid growth of remote workforces and cloud-based applications, organizations are finding that remote access VPN is neither optimized for the cloud nor secure. An innovative approach is necessary to account for today’s application mix: A modern architecture for the mobile workforce. Today’s mobile workforce needs access to the data center, the internet, and applications in public, private, and hybrid clouds. In other words, the proper architecture should optimize access to all applications, wherever they or the users are located.
Modern architectures for the mobile workforce are designed to address the limitations of traditional VPNs and provide a more efficient and secure user experience. These architectures leverage cloud-based security services, such as Zero Trust Network Access (ZTNA) and Secure Access Service Edge (SASE), to provide granular access control, threat protection, and optimized routing. By distributing security and networking functions closer to the user, these architectures can reduce latency, improve performance, and enhance the overall user experience.
Remote access VPN has been an enterprise network staple for years. However, as enterprises rapidly adopt more cloud applications, their security and networking needs are changing fundamentally. After a long history of the VPN’s evolution, so too must the solutions.
