AI-use cyber risk
Cyber risk around AI use ranks third, appearing in the ranking for the first time in 2026.
Talent / METI context
Specialist capacity
METI cites an estimated shortage of approximately 110,000 cybersecurity workers in Japan, based on a private 2023 survey. This is not a METI measurement of today’s exact gap.
The National Police Agency’s 2025 report records 226 reported ransomware incidents. The figure concerns reports in 2025, rather than all attacks or a prediction of future losses. NPA report, released 10 March 2026

Turn Uncertainty Into a Prioritized Plan
| Business pain point | Why it matters | How Axton can support |
|---|---|---|
| Unknown assets or access | Unowned systems and accounts make risk decisions difficult. | Asset/access mapping and ownership clarification. |
| Excessive or stale privileges | Old access may remain after role changes or departures. | Access-review planning and joiner/mover/leaver procedures. |
| Vulnerability and exposure backlog | Unprioritized findings can remain unresolved. | Business-impact triage, remediation ownership and tracking. |
| Ransomware readiness gaps | Recovery can stall when dependencies and decisions are unclear. | Recovery-priority review and incident-readiness planning. |
| Supplier and contractor dependencies | External access or service disruption can affect internal operations. | Risk-based supplier requirements and evidence workflows. |
| Cloud / SaaS governance | Configuration, ownership and data responsibilities can be fragmented. | Service inventory, responsibility mapping and policy support. |
| Unclear AI usage | Data and action boundaries may be undefined. | Approved-use policy, access boundaries and review requirements. |
| Incident coordination gaps | Teams may not know who can authorize urgent decisions. | Roles, escalation, communications and exercise planning. |
| IT / OT boundaries | Changes can affect availability and production safety. | Dependency review and coordination with qualified specialists where required. |
| Limited specialist capacity | Internal teams may struggle to cover every specialist discipline. | Scoped support planning and implementation coordination. |
Practical Support From Risk Review to Readiness
The eight areas below build on security assessment, endpoint protection planning, policy support, incident readiness and awareness support. Possible outputs depend on the systems, evidence and delivery scope agreed for the engagement.
A
Cyber Risk & Security Assessment
Security work needs a shared view of what matters most. A business-led review connects current controls, systems and dependencies to operational impact.
Questions to resolve
- Which operations and data are critical?
- Who owns the assets, risks and improvement decisions?
Possible support
Axton can support interviews, system/risk review, asset and access mapping, gap identification and a prioritized improvement plan. Technical assessment methods and specialist execution are agreed separately.
Possible deliverables
A current-state summary, executive risk register, ownership map and phased security roadmap.
B
Identity & Access Security
Accounts often outlast the business need that created them. Employee, contractor and administrator access should follow an accountable lifecycle.
Questions to resolve
- How is access requested, approved and removed?
- Where are privileged or shared accounts, and who reviews them?
Possible support
Support may include access inventories, review procedures, multi-factor authentication planning, privileged-access approvals and joiner/mover/leaver workflows. Changes depend on the existing systems and approved scope.
Possible deliverables
An access-review checklist, responsibility matrix and account lifecycle procedure.
C
Vulnerability & Exposure Management Support
A list of findings is useful only when it leads to decisions and verified remediation. Internet-facing services, remote access and endpoint protection need owners and review cycles.
Questions to resolve
- Which findings affect critical operations or exposed services?
- Who can approve changes, and what evidence confirms completion?
Possible support
Axton can help organize existing findings, prioritize exposure by business impact, plan endpoint protection, track remediation and coordinate implementation. Scanning or intrusive testing is not assumed to be included.
Possible deliverables
A prioritized remediation backlog, named owners, target review dates and closure-evidence checklist.
Can Your Business Continue Operating If a Critical System Becomes Unavailable Tomorrow?
D
Ransomware & Cyber Resilience
Resilience is the ability to sustain essential work and recover when disruption occurs. Backup availability alone does not establish that the business can recover in the right order.
Questions to resolve
- What must recover first, and what does it depend on?
- Have restoration, access and decision responsibilities been reviewed?
Possible support
Axton can support critical-system and dependency review, backup/recovery readiness discussions, response-role definition, communications planning and tabletop preparation. Recovery testing or technical response requires an agreed implementation scope.
Possible deliverables
A recovery-priority map, readiness checklist, decision/escalation matrix and improvement actions from exercises.
The NPA’s 2025 report documents ransomware incidents that disrupted business activity. A readiness review should connect system recovery with continuity priorities, authorized decisions and communications to employees, customers and suppliers.
Review critical dependencies, recovery access, backup separation and restoration assumptions; agree who can authorize isolation or recovery; rehearse contact routes and fallback operations; record lessons and revisit the plan. These measures reduce uncertainty but do not guarantee attack prevention or recovery outcomes.

Security Across the Organizations You Depend On
E
Supply Chain & Third-Party Security
An external weakness can become an internal operational problem through shared access, data handling or service dependency. Risk varies by supplier role and the impact of disruption.
Questions to resolve
- Which suppliers can access systems or handle sensitive data?
- What would happen if an outsourced service or group-company connection failed?
Possible support
Support may cover risk-tiered requirements, evidence inventories, review/renewal procedures, remediation tracking and responsibility mapping for suppliers, contractors, outsourced providers, IT vendors, cloud/SaaS providers and group companies.
Possible deliverables
A third-party inventory, risk-tiering criteria, evidence checklist and supplier-security review workflow.
IPA’s threat ranking and METI’s SCS material provide context for supply-chain attention. Requirements should be proportionate: an IT administrator, a production dependency and a supplier without system access need different review depth.
Preparing for Japan’s SCS Supply Chain Security Evaluation System
SCS is voluntary. Company applications for ★3 and ★4 are currently targeted around the end of FY2026 (January–March 2027); IPA’s published FAQ describes an operational start around March 2027. Timing and details remain subject to official updates. Axton does not claim official SCS certification or assessment authority. METI: policy and voluntary participation / IPA: planned start
The framework helps buyers and suppliers communicate expected measures across business and IT-service supply chains. Axton’s possible preparation support includes current-state review, evidence inventory, requirement mapping, gap identification, remediation planning and supplier-security workflow design, subject to agreed scope.
| Question | Answer |
|---|---|
| Is SCS mandatory? | No. Participation is voluntary; a buyer and supplier may agree requirements through their trading contract. |
| When does it begin? | Company applications for ★3/★4 target the end of FY2026 (January–March 2027). IPA indicates operations around March 2027; official updates can change details. |
| Why does it matter? | It helps buyers and suppliers communicate expected measures and make security status more visible. |
| Can Axton certify us? | No official SCS certification or assessment authority is claimed. Preparation support is separate from the scheme’s formal evaluation. |
| What can we prepare now? | Identify owners, inventory evidence, map published requirements, identify gaps and plan remediation and review workflows. |
Status checked 7 October 2026. IPA has already begun separate applications for provider designation; that does not mean company ★3/★4 applications are open. Use IPA’s operational updates for the current procedures.

Make Decisions and Responsibilities Clear Before an Incident
F
Incident Readiness & Security Governance
An incident exposes gaps in authority as well as technology. Management, IT, business teams and external support need clear roles before disruption.
Questions to resolve
- Who receives reports and who can authorize urgent action?
- How are employees, customers and suppliers kept informed?
Possible support
Axton can help define policies, escalation routes, response roles, communication templates, exercise plans and review cycles. Live technical response and specialist investigation are separately scoped.
Possible deliverables
An incident-readiness playbook, decision matrix, contact tree, tabletop agenda and governance review calendar.
METI / IPA’s management guidelines place leadership and communication within security management. Operational ownership stays with the organization, with specialist responsibilities explicitly agreed.
- Prepare
Roles, contacts and recovery priorities
- Detect / Report
Staff and service-provider reporting routes
- Triage
Assess impact and establish ownership
- Contain
Authorized action with technical specialists as required
- Decision & Escalation
Agreed authority and business priorities
- Recover Critical Operations
Approved recovery sequence and checks
- Communicate
Employees, customers, suppliers and relevant stakeholders
- Learn & Improve
Record findings and revise readiness
An explanatory readiness model, not an official IPA/METI framework or a promise of emergency response. Actual response is iterative; communications continue throughout. Technical containment and recovery require authorized, appropriately qualified execution.
Put Useful AI Inside Clear Business Boundaries
G
AI Security & Governance
AI can create business value, but enterprise use needs clear boundaries around data, access, authority and accountability. Unapproved tools — often called shadow AI — can bypass the intended review process.
Questions to resolve
- Which tools, services and models are approved for which data?
- What can AI access or do, and when is human review required?
Possible support
Possible support includes AI-use policy, sensitive-data handling rules, account and connection boundaries, model/service selection criteria, action approvals, human-review design and logging/accountability requirements.
Possible deliverables
An approved-use register, AI authority matrix, review checklist and logging requirements.
IPA’s 2026 AI-use risk category is a reason to review how AI is used, not to treat AI as inherently unsafe. See our governed enterprise AI guide and human-in-the-loop governance article for practical boundaries and meaningful review.
Security Planning That Respects Production
H
OT / Factory Security Readiness
IT security and OT security have different operating constraints. Factory decisions must account for production availability, industrial control systems, legacy equipment, long equipment lifecycles and production safety.
Questions to resolve
- Which IT/OT connections and vendor-maintenance routes support production?
- How are changes approved without undermining availability or safety?
Possible support
Axton can support OT/factory-security risk discussions and coordination within agreed project scope, involving qualified specialists or implementation partners where specialist assessment is required. Any specialist arrangement and technical work must be agreed; it is not assumed to be in place.
Possible deliverables
A factory dependency map, vendor-access questions, boundary-risk notes and a specialist-assessment brief.
Review manufacturing/IP data, vendor access, maintenance windows and change authority alongside production needs. METI’s factory-system guidelines Ver. 1.1 and getting-started appendix provide factory-specific context. A generic office-IT change process should not be applied to industrial equipment without considering those constraints.
Security Expertise Is Difficult to Scale Internally
METI’s May 2025 talent report cites a private estimate of roughly 110,000 missing cybersecurity workers, based on the 2023 survey. It supports the need to plan capacity; it is not an exact current count of available specialists.
Keep risk acceptance, priorities and business decisions with named internal owners. Define where external expertise is needed, who is accountable for delivery, how work is reviewed and how knowledge returns to the internal team.
Axton’s role can combine Japanese client-facing coordination, scoped expert-support planning, clear accountability and implementation coordination. Specialist availability, qualifications, methods and responsibilities must be confirmed for each engagement.
Make Security Processes Repeatable and Accountable
Security policies are stronger when the surrounding business process is repeatable and accountable. Requests, decisions, exceptions and evidence should have owners and a review trail.
- Joiner/mover/leaver requests and access removal
- Privileged-access requests and approvals
- Supplier-security questionnaires and evidence review
- Remediation ownership, due dates and closure evidence
- Incident reporting and escalation
- Security-exception approval and periodic reassessment
Our Enterprise Automation service can help coordinate these business processes, including governed AI where useful. Fluyenta is an enterprise orchestration platform, not a cybersecurity product. A workflow supports controls and accountability; it does not replace protective tools or specialist security judgment.
- Supplier / Contractor
Identify relationship and service owner
- Security Requirements
Set expectations proportionate to risk
- Questionnaire / Evidence
Collect information through an agreed route
- Risk Review

Keep decisions, evidence and actions
An example of accountable business coordination, not an official SCS assessment, certification procedure or implemented customer case. Evidence, review depth and decision rights depend on the relationship and company policy.
Security Priorities Depend on the Operating Context
Construction & Infrastructure
Project information, distributed teams, subcontractor access and supplier dependencies need ownership. Readiness planning can connect site continuity with office systems and project decisions.
Manufacturing & Industrial Operations
Production availability, industrial systems, vendor access and confidential manufacturing information require coordination between IT, operations and appropriately qualified specialists.
Multi-Company & Enterprise Groups
Shared systems, group identities, outsourced services and uneven local procedures can obscure responsibility. Common requirements and clear local ownership help structure review.
Growing Businesses & SMEs
Start with proportionate controls, important accounts, backups, incident contacts and supplier expectations. IPA’s FY2024 survey identifies cost and specialist-resource barriers to responding to buyer requests.
IPA — FY2024 SME survey, published 27 May 2025
