List of the Top On-Prem Zero Trust Network Access (ZTNA) Solutions in 2026

An all-encompassing data security package that features Zero Trust Network Access (ZTNA), two-factor authentication (2FA), and privileged access management (PAM) is now available. Additionally, it incorporates SQL firewalls and data access management (DAM) to bolster protection. This solution is designed to safeguard companies against data breaches and cyber threats. Furthermore, it assists organizations in adhering to compliance standards and fulfilling cyber insurance obligations, ultimately enhancing their overall security posture.

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.

NetFoundry is an identity-first Zero Trust networking platform built to secure workload connectivity across applications, APIs, cloud infrastructure, data centers, AI agents, industrial systems, and distributed sites. The platform is based on OpenZiti, the open source Zero Trust networking technology created and maintained by NetFoundry. Rather than connecting systems primarily by IP address, NetFoundry assigns cryptographic identities to workloads and uses policy to determine which identities can communicate with specific services. Authorized sessions are established through outbound-only, end-to-end encrypted connections, leaving protected services without inbound ports that can be scanned or directly attacked. This architecture can reduce reliance on traditional VPNs, firewall rules, network address translation, static routes, and IP allowlists when connecting distributed workloads. Identity-based microsegmentation allows teams to create least-privilege paths between individual services and helps limit lateral movement if one system is compromised. Site-to-site capabilities connect clouds, branches, plants, partner networks, and other environments without requiring conventional tunnel management or unique IP address ranges. NetFoundry also provides controls for AI agents so organizations can govern machine-to-machine access, apply consistent policies, and track interactions across AI infrastructure. API security capabilities can keep services unreachable until authentication and authorization are complete, while OT and IoT features help secure legacy or sensitive environments without modifying individual controllers. Software vendors and solution providers can embed NetFoundry connectivity into their own products to reach customer environments without requiring customers to expose inbound ports or configure traditional VPN access.
