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.

CloudConnexa is OpenVPN's cloud-delivered Zero Trust Network Access (ZTNA) platform that also delivers core Security Service Edge (SSE) capabilities, letting organizations replace legacy VPN infrastructure with a fully managed, cloud-native service. Signing up provisions a private overlay network, conceptually a virtual distributed router and next-generation firewall, spanning 30+ global regions connected in a full-mesh topology for low-latency, redundant routing between points of presence. Private infrastructure joins this network through Connectors: Network Connectors attach entire private networks (offices, data centers, VPCs/VNets in AWS or Azure), while Host Connectors attach individual servers or IoT devices. Hosts run an OpenVPN client to expose specific services. Remote users, sites, and cloud resources connect over encrypted OpenVPN tunnels, with Data Channel Offload (DCO) support for higher throughput on Linux. Access is governed by identity-based, role- and group-based policies, with SAML, LDAP, and SCIM integration so admins scope users to only the resources they need. Application domain-based routing cloaks real IP addresses, enabling microsegmentation without exposing server infrastructure. Built-in Cyber Shield security bundles DNS content filtering across 43+ categories, intrusion detection/prevention (IDS/IPS), Device Identity Verification & Enforcement (DIVE) for posture checks, and two-factor authentication. Admins get audit logging, SIEM integration, and alerting for visibility and troubleshooting. It's all managed from a single cloud dashboard, giving organizations scalable, zero-trust connectivity without operating their own VPN servers.

Cato empowers its clients to progressively modernize their wide-area networks (WAN) for a more digital-centric business environment. The Cato SASE Cloud serves as a global, integrated, cloud-native solution that ensures secure and efficient connections across all branches, data centers, personnel, and cloud services. This innovative system can be implemented gradually to either replace or enhance existing legacy network infrastructures and disparate security solutions. The concept of Secure Access Service Edge (SASE), which was introduced by Gartner, represents a novel category in enterprise networking. It merges SD-WAN with various network security solutions such as Firewall as a Service (FWaaS), Cloud Access Security Broker (CASB), Secure Web Gateway (SWG), and Zero Trust Network Access (ZTNA) into a cohesive, cloud-based service offering. Historically, network access was handled through isolated point solutions, leading to a fragmented approach that increased complexity and expenses, ultimately hindering IT responsiveness. By adopting SASE, businesses can significantly accelerate the development of new offerings, expedite their market entry, and swiftly adapt to evolving market dynamics and competitive pressures. This transformative approach not only enhances operational efficiency but also positions enterprises to thrive in an ever-changing digital landscape.

Effectively oversee your remote team by enabling the rapid setup of both company-issued and personal devices, as well as unmanaged contractor endpoints. Minimize the risk of data breaches through a Zero Trust security framework that ensures secure access. This approach delivers ongoing verification of user and device identities, thereby decreasing the potential attack surface. By utilizing this method, employees benefit from enhanced access, improved security measures, and better performance relative to conventional VPN solutions. The foundation of security is rooted in access control. The CloudGen Access Zero Trust framework establishes unrivaled control over access for users and devices, eliminating the performance drawbacks associated with traditional VPNs. It allows for remote, conditional, and contextual resource access while mitigating excessive privileges and third-party risks. Through CloudGen Access, both employees and partners can seamlessly connect to corporate applications and cloud services without introducing additional vulnerabilities, ensuring a more fortified digital environment. This innovative approach not only secures sensitive information but also enhances overall operational efficiency.

It is essential to proactively identify and eliminate both internal and external threats that may jeopardize your organization. Leading global corporations and government entities rely on our top-notch, effective secure access solutions. Our ZTNA solution is designed to strengthen and streamline network security by offering a comprehensive suite of features. Ultimately, this not only mitigates risk but also ensures that consumers enjoy a smooth and secure connection to your digital services while safeguarding sensitive data.

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. AI security features govern agent-to-application and agent-to-API communication while supporting centralized policy and usage tracking. The platform can also secure APIs, OT systems, IoT environments, vendor connectivity, and software products that need embedded Zero Trust networking. NetFoundry is intended for enterprises, security teams, infrastructure operators, solution providers, and organizations managing complex distributed environments that require controlled and auditable workload connectivity.
