Built for financial data security
Equity data is sensitive. Nstock is designed with security-first architecture and handled under Japan's APPI framework.
Your equity data, protected
Every layer of Nstock is built to keep your company's sensitive ownership information secure, accessible only to authorized users.
End-to-End Encryption
All data is encrypted at rest using AES-256 and in transit with TLS 1.3. Cap table data, grant documents, and shareholder records are never stored unencrypted.
Role-Based Access Control
Granular permissions let you control exactly who can view, edit, or export equity data. Admin, editor, and viewer roles available per company account.
Single Sign-On Support
SSO integration on Growth and Scale plans. Connect your existing identity provider to manage access without separate credentials.
Audit Logs
Every cap table change, grant action, and export is logged with timestamp and user attribution. Full audit trail for your lawyers and compliance team.
Japanese Data Residency
All data is processed and stored in Japan. Your company's equity information never leaves Japanese data center infrastructure.
Automated Backups
Daily encrypted backups with 90-day retention. Point-in-time recovery available on Scale plans. Your equity records are never at risk of loss.
Designed with APPI compliance in mind
Nstock is built to comply with Japan's Act on the Protection of Personal Information (APPI). We do not sell or share your company's equity data with third parties and never use your data to train models.
- APPI-compliant data handling and retention policies
- No third-party sharing of equity or shareholder data
- Model training opt-out enforced by default
- Annual security reviews by independent assessors
