PacketGo ZTNA is a zero-trust access control platform designed to eliminate blind spots in perimeter-based security using advanced data flow control technology. It addresses the security vulnerabilities of traditional methods, such as IP-based identification and L7 authentication, through an integrated system called the Data Flow ID. This approach enables precise identification of actual communication entities and authorizes communication after authentication, delivering a "strengthened authentication" model of zero trust architecture. Furthermore, it integrates access control processes across all network layers—L3, L4, and L7—enhancing both visibility and usability. Adhering to zero trust principles, the platform continuously validates users and devices even after initial authentication, managing threats like policy violations, authentication bypasses, and unauthorized access in real time. With PacketGo ZTNA, users can securely manage access to workloads, communications, and data across various environments anytime, anywhere.
