Open Source Alternatives to Zscaler Private Access

A zero trust network access (ZTNA) solution that provides secure connectivity between authorized users and specific private applications. The product brokers one-to-one connections to apps, workloads, and OT systems without exposing them to the public internet or granting direct network access. It includes capabilities for AI-powered app segmentation, workload-to-workload segmentation, and privileged remote access for RDP, SSH, and VNC systems. The platform is designed for hybrid workforces, third-party contractors, and industrial IoT environments to replace legacy VPNs and VDI. It is deployed as a cloud-native service that includes inline traffic inspection and data loss prevention to prevent private app compromise. This solution enables secure access for remote users, headquarters, branch offices, and external partners across any device or location.
