Distinguishing Public METI/IPA Programs from Corporate Advisory

For general public inquiries regarding the national "Cybersecurity Otasuketai Service" certification scheme administered by Japan's METI and IPA, please refer first to the official METI policy page ↗. If your organization seeks independent RISS consultation on selecting IPA-certified defenses, preparing for METI's October 2026 SCS (Star-3 / Star-4) evaluation, or modernizing your internal IT infrastructure, our team at e@ok.st will gladly assist you.
