OpenVPN Access Server is a self-hosted Zero Trust Network Access (ZTNA) solution you deploy into your own environment — on-prem or your AWS, Azure, or GCP account — so tunnel traffic and configuration never touch a third-party network. Access is enforced by application, not IP or subnet: each user reaches only the app they're entitled to, identified by domain name, with no visibility into anything else. That structurally blocks lateral movement — there's no connectivity path for a breach to exploit. With Access Server Link, deployment is a guided setup (hostname, cloud, region, password) with SSL certificates auto-provisioned and renewed, removing manual cert management as an attack surface. Entitlements tie to hostname, so they survive IP changes and autoscaling without rework. Your instance stays fully under your control, preserving the data ownership and audit posture required for HIPAA, SOC 2, and GDPR — full sovereignty over the control plane, with SaaS-level simplicity. The admin portal replaces SSH-based management: users, certificates, and access policies are configured through a browser, so shell access isn't required, shrinking your attack surface. The Zero Trust App Broker mediates every connection through a placeholder IP scoped to one authorized application — users never learn the real destination, so a compromised credential can't be used to probe or discover other systems. This enforces least privilege by design, not just by policy that can drift or be misconfigured. Client apps span Windows, macOS, iOS, Android, and Linux, so identity- and application-based controls apply consistently across devices. Deployment runs through preconfigured templates on AWS, Azure, and GCP, giving security teams repeatable, auditable rollouts.

NetFoundry is a Zero Trust workload connectivity platform that secures communications between applications, APIs, AI agents, machines, sites, cloud services, and operational technology environments. The platform is built on OpenZiti and replaces IP-based trust with cryptographic identities and policy-controlled connectivity. Instead of exposing services through inbound ports, both sides of a connection dial outward and establish an encrypted path only after identity verification and authorization. This approach can help organizations reduce exposed attack surfaces, prevent unauthorized lateral movement, and avoid many firewall, NAT, routing, and VPN configuration requirements. NetFoundry provides identity-based microsegmentation that creates least-privilege communication paths between specifically authorized workloads. Its site-to-site connectivity capabilities support distributed networks, cloud environments, partner systems, and locations with overlapping IP address ranges without requiring conventional tunnel architectures.
