After South Korea's National Intelligence Service announced a Multi-Layer Security (MLS) framework in 2024 and released the N2SF Guideline 1.0 in 2025, the domestic public security market is shifting away from the uniform network segregation policy that had been in place for roughly 18 to 19 years toward a system that applies differentiated security controls based on information sensitivity.
Industry observers note that the market's center of gravity is moving from network-segregation-dedicated hardware toward platforms and security-as-a-service offerings that integrate asset identification, risk scoring, Zero Trust, and data protection.
The Korea Internet & Security Agency (KISA), together with the Ministry of Science and ICT, is pursuing a 2026 national network security framework adoption support program and selected six consortia of public agencies and domestic security firms, with SGA Solutions participating in three of those projects to build authentication and access-control systems for public institutions.
This policy shift has created a competitive landscape in which multiple security vendors including AhnLab, IGLOO Corporation, INITECH, Penta Security, SoftCamp, Hunesion, and Dream Security are entering simultaneously, each pursuing specialized strategies in areas such as Zero Trust, data classification, or cross-domain solutions.
An increasingly sophisticated threat environment—featuring generative-AI-enabled phishing and malware alongside a string of ransomware incidents—is also cited as a backdrop supporting demand for integrated security.
Still, some industry experts caution that N2SF compliance is not a matter of adopting a single solution but requires an integrated combination of consulting, technology, and operations, suggesting the market's full expansion could take considerable time.
