In this groundbreaking research paper, we delve into the realm of enterprise-grade hosted VPN services, leveraging open-source, cost-effective tools within the robust AWS infrastructure. In the dynamic landscape of information technology, the pursuit of solutions that are both effective and financially prudent is imperative. Notably, the conventional approach to VPN services often involves substantial expenditures, with industry giants like Palo Alto demanding millions of dollars annually for their services. However, this paper advocates for a transformative paradigm shift wherein organizations can develop and host their VPN services, offering heightened customization and control through proprietary infrastructure. The proposed solution represents a significant milestone, especially for security-focused companies aiming to host comprehensive VPN services independently, thereby gaining complete oversight of each facet of the service edge. Despite the promise of this approach, successful implementation necessitates thorough research and meticulous planning. Nonetheless, the potential benefits are substantial, with the ability to deploy such solutions within a few weeks across diverse business units. Hosted VPN services, implemented in this manner, have the capability to fortify the entire infrastructure from end to end, markedly enhancing security measures and access control. The foundation of this approach lies in the strategic utilization of OpenVPN as the client and pfSense as the firewall/ router, orchestrating traffic routing and providing a robust security layer for internet-bound traffic. Through the integration of various certificates within the OpenVPN client, precise management of user connections to the firewall is achieved. The resultant configuration ensures enterprise-grade firewall security, effectively mitigating internet threats by blocking access to non-essential sites. The synergistic use of OpenVPN and pfSense not only bolsters security but also offers a scalable and flexible solution that aligns with the specific needs of diverse business environments.
