Provides hardware-enforced network access control at the switch level, a direct operational control for network segmentation and access security.
Involved in a corporate transaction with Daekyo CNS in mid-2026, though public deal details and terms remain limited.
Switch-level network access security is an established approach; no evidence of a distinctly new technical direction was found in this pass.
Long-standing operation in the South Korean network security market suggests sustained customer use, though no independent efficacy data was found.
Hardware-enforced network access control remains relevant for enterprise network segmentation, particularly in regulated South Korean markets.

Founding year is undisclosed in available sources.
