OpenZiti

What is OpenZiti?

OpenZiti is an open-source zero trust overlay network that provides secure connectivity across distributed systems. It establishes a full mesh network architecture where all nodes can communicate securely without relying on traditional perimeter-based security models. The platform includes native two-factor authentication support and offers client applications for Windows, macOS, Linux, iOS, and Android, enabling secure access across desktop and mobile devices. OpenZiti operates on zero trust principles, requiring explicit authentication and authorization for all network traffic regardless of source location. The system is designed for organizations seeking to replace or supplement traditional VPN infrastructure with a more granular, identity-based access model. It serves teams managing remote access, securing microservices communication, and protecting sensitive infrastructure from unauthorized access. Key characteristics include full mesh topology capabilities, built-in identity verification, multi-platform client support, and a completely open-source codebase available on GitHub. The project maintains active development with continuous integration pipelines and comprehensive documentation. OpenZiti is suitable for security-conscious organizations, development teams implementing zero trust architecture, and infrastructure teams managing complex network access requirements. Being open source with no licensing costs, it provides a viable alternative to proprietary zero trust solutions while allowing organizations to audit and customize the codebase to their specific requirements.
