en.Wedoany.com Reported - Piolink (CEO Jo Young-cheol) announced on the 15th that it has registered a technology patent in South Korea, the United States, and Japan for implementing micro-segmentation using the "T-Front Security Switch."

The registered patent is titled "Method for Implementing Zero Trust Role-Based Micro-Segmentation Based on Network Switches, and Network Controller and Access Switch Using the Same." This patent enables micro-segmentation using only the network infrastructure itself, without requiring agent installation or additional security devices. By upgrading existing L2/L3 switches to security switches, it minimizes deployment complexity and cost burdens.

This patent is considered a realistic alternative for organizations transitioning to the "National Network Security Framework (N2SF)." N2SF requires zero trust-based access control, and this technology enables endpoint control and micro-segmentation within the network itself. Piolink's zero trust solution "T-Front ZT" incorporates this technology. After establishing micro-segmentation access policies through the central decision management system "T-Controller," the security switch blocks and isolates endpoints exhibiting abnormal behavior according to the policies. Even if ransomware or malicious code infiltrates, it can block lateral movement within the internal network, minimizing the scope of intrusion. The company emphasizes that this technology implements the separation and isolation principles required by N2SF, as well as the least privilege principle of the zero trust security model.

Piolink CEO Jo Young-cheol stated, "Many organizations acknowledge the necessity of introducing N2SF and zero trust but are concerned about deployment costs and operational complexity. Since micro-segmentation can be achieved simply by replacing old switches with security switches, 'T-Front ZT' is a realistic N2SF transition solution."
