List of the Top Zero Trust Security Software for Keycloak in 2026

Kasm Workspaces enables you to access your work environment seamlessly through your web browser, regardless of the device or location you are in. This innovative platform is transforming the delivery of digital workspaces for organizations by utilizing open-source, web-native container streaming technology, which allows for a contemporary approach to Desktop as a Service, application streaming, and secure browser isolation. Beyond just a service, Kasm functions as a versatile platform equipped with a powerful API that can be tailored to suit your specific requirements, accommodating any scale of operation. Workspaces can be implemented wherever necessary, whether on-premise—including in Air-Gapped Networks—within cloud environments (both public and private), or through a hybrid approach that combines elements of both. Additionally, Kasm's flexibility ensures that it can adapt to the evolving needs of modern businesses.

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.

ZTXGate is an advanced Zero Trust Network Access (ZTNA) solution that combines the user-friendly aspects of a modern SaaS control plane with the advantages of on-premises software, offering flexibility in deployment, data sovereignty, and capabilities that limit the impact of security breaches. Each client benefits from a distinct single-tenant instance that maximizes both security and performance outcomes. The platform supports identity federation through OIDC SSO for the administrative interface, featuring a registry per provider, implementation of PKCE, mapping from groups to roles, and a local break-glass mechanism. It also enables inbound provisioning via SCIM 2.0 through a dedicated hardened listener with per-token bearer authentication, CIDR allowlisting, and rate limits in place. This system adeptly links identifiers across protocols, ensuring that an OIDC login corresponds with a SCIM-provisioned user under a unified identity. In addition, ZTXGate features a flexible biometric step-up solution that can issue push challenges using its proprietary authenticator (ZTXBAS), along with Okta Verify Push and Duo Push, all managed under a cohesive policy framework. Resource-specific policies dictate the backend utilized, and API credentials are safeguarded through secure encryption while at rest. Moreover, the platform integrates MDM and EDR device posture as essential components of its policy framework, with support for integration with Microsoft Intune, Defender, and SentinelOne Singularity, thereby bolstering both security posture and compliance measures. This comprehensive approach ensures that organizations have robust protection and adaptability in their security environments.
