Piolink said on Sunday it completed patent registrations in South Korea, the United States and Japan for a technology that implements micro-segmentation using its Tfront security switch. The company said the technology enables zero-trust-based micro-segmentation through network infrastructure itself, without installing separate agents or adding security equipment. It said it can reduce deployment complexity and costs and help institutions prepare for a transition to the National Network Security Framework (N2SF).

Piolink on April 23 held the “Piolink Resilience Summit 2026” at The Westin Josun Seoul Parnas and underscored its identity as a technology company focused on strengthening cyber resilience. Chief executive Cho Young-cheol said resilience that sustains business during crises is central to corporate survival and growth. He said perfect defence is impossible and stressed maintaining services and rapid recovery after attacks.
