OpenVPN Access Server vs. Bowtie

OpenVPN Access Server is a self-hosted Zero Trust Network Access (ZTNA) solution that runs inside your own environment — on-prem or your AWS, Azure, or GCP account — keeping tunnel traffic and configuration off any third-party network. Access is scoped to the application, not the IP or subnet: each user is routed only to the specific app they're authorized for, identified by domain name, with nothing else on the network visible to them. That makes lateral movement structurally impossible, not just restricted by policy. Access Server Link turns setup into a guided flow (hostname, cloud, region, password), with SSL certificates provisioned and renewed automatically, eliminating manual certificate handling as a source of risk. Because entitlements are bound to hostname rather than IP, they hold up through IP changes and autoscaling with no manual rework. Your instance remains entirely under your control, giving you the data ownership and audit trail needed for HIPAA, SOC 2, and GDPR — full control of the stack, delivered with SaaS-level ease. Administration happens through a browser-based portal instead of SSH: users, certificates, and access rules are managed without shell access, narrowing your attack surface. The Zero Trust App Broker routes each connection through a placeholder IP tied to a single authorized app — the real destination stays hidden, so a stolen credential offers no way to scan or reach other systems. Least privilege is built into the architecture, not left to policy that can drift. Native clients cover Windows, macOS, iOS, Android, and Linux, keeping identity- and app-based controls consistent across every endpoint. Templated deployment on AWS, Azure, and GCP means security teams get standardized, auditable rollouts rather than one-off manual builds.

Bowtie serves as a cutting-edge security solution aimed at bolstering enterprise network protection by enhancing speed, intelligence, and resilience. Its innovative distributed overlay model guarantees that users benefit from superior security measures without facing any delays in performance. By establishing encrypted connections that link devices directly to private resources, Bowtie eradicates the need for intermediary networks, which traditionally manage traffic. This novel strategy not only facilitates faster access but also reduces the attack surface and lowers the risks associated with centralized points of failure. Users are no longer required to route their internet traffic through potentially vulnerable cloud-based processing centers. With Bowtie’s Secure Web Gateway (SWG), they can enjoy direct internet access, which helps to maintain their browsing experience without any adverse effects. The enforcement of security measures occurs directly on user devices, which significantly mitigates the disadvantages associated with cloud processing centers. Moreover, Bowtie incorporates user-invisible agents that ensure seamless authentication, encryption, and access enforcement, all while keeping the user experience uninterrupted. The system is elegantly consolidated into a single agent and an administrative console, allowing for streamlined management of all security functionalities. This comprehensive approach ultimately simplifies security processes for enterprises, making it easier for them to safeguard their networks against emerging threats. As a result, Bowtie not only enhances security but also empowers users and organizations with greater control over their digital environments.
