N2SF & Zero Trust Transition Consulting
Design a security transition around your information.
From classification to daily operations.
For national and public institutions adopting Korea’s National Network Security Framework (N2SF), we review information and systems, define classification criteria and security measures, and plan implementation.
N2SF addresses information protection needs and processing environments. Zero Trust develops controls for access to resources. We connect these perspectives in a transition plan suited to the institution’s work and operating conditions.

Frequently asked questions
Does N2SF mean opening every network?
It means designing protection measures for information classifications, environments and applicable requirements. We review where separation or blocking is needed alongside permitted uses.
Can the engagement cover AI use?
We review information permitted for external AI services, protective measures and internal approval procedures in the relevant classification and service environment.
What follows initial classification?
Maintain decision evidence as work, information and systems change, with procedures for access control, exceptions and implementation tracking.
The scope of work and deliverables are determined by the target environment and the agreed engagement.
