This document describes the security architecture and practices of the AI Document Intelligence Platform as currently implemented.

Certification Status: The platform is in early-stage development (MVP). We do not currently hold any formal security certifications (SOC 2, HIPAA, ISO 27001, GDPR compliance audit, etc.). Security certifications are planned for future development phases as the platform matures.

The platform includes security-focused architecture and practices:

Authentication & Authorization:

• ✅ Supabase Auth with email/password and OAuth 2.0 support
• ✅ JWT-based API authentication
• ✅ Role-based access control (RBAC) with user/admin/manager roles
• ✅ Row-level security (RLS) policies in PostgreSQL database

Data Encryption:

• ✅ HTTPS/TLS 1.3 for all connections
• ✅ Passwords hashed with bcrypt
• ✅ Document storage in Supabase with encryption support
• ✅ API keys for user authentication

Code Security:

• ✅ TypeScript with strict type checking (prevents many common vulnerabilities)
• ✅ Input validation on API endpoints
• ✅ SQL injection prevention through parameterized queries
• ✅ CSRF protection via SameSite cookies
• ✅ Rate limiting on API endpoints
• ✅ Error boundary components for error handling

Development Practices:

• ✅ Dependency scanning (npm audit, Dependabot integration)
• ✅ Code review process via Git pull requests
• ✅ Secure environment variable management (no secrets in code)
• ✅ Open source components from trusted providers (Next.js, React, TypeScript)

Not Implemented:

• ❌ SOC 2 Type II certification (not audited)
• ❌ HIPAA compliance (healthcare-grade features not implemented)
• ❌ GDPR audit/certification (compliance features exist but not audited)
• ❌ ISO 27001 certification (not audited)
• ❌ 24/7 security monitoring (not staffed)
• ❌ Dedicated security operations center
• ❌ Commercial breach insurance
• ❌ Formal incident response team
• ❌ Penetration testing by external firms
• ❌ SLA guarantees (service available on best-effort basis)

Why These Limitations Exist: This is an early-stage MVP (minimum viable product) built by a small team. Enterprise-grade security certifications require significant infrastructure, staffing, audit costs, and insurance. These are planned for future versions as the platform grows.

The platform implements multiple security layers:

┌────────────────────────────────────────────────────┐
│  Client Application (Your Code)                    │
│  - Validate inputs before API calls                │
│  - Use HTTPS connections only                      │
│  - Store API keys securely                         │
└──────────────────┬─────────────────────────────────┘
                   │

└────────────────────────────────────────────────────┘

Preventive Controls:

• Type-safe code with TypeScript strict mode
• Input validation on all API endpoints
• Parameterized SQL queries (Supabase)
• HTTPS/TLS encryption for all connections
• Authentication required for protected routes
• Role-based access control (RBAC)
• Rate limiting on API endpoints
• Secure password hashing (bcrypt)

Detective Controls:

• Error logging and error boundaries
• Application error tracking (Sentry integration available)
• Database audit logs (via Supabase)
• Version control history (Git)

Corrective Controls:

• Error handling and graceful degradation
• Backup and recovery (via Supabase automated backups)
• Incident response procedures documented below
• Security patches for dependencies

Encryption in Transit:

• Protocol: TLS 1.3 (all HTTPS connections)
• Enforcement: All API endpoints require HTTPS
• Implementation: Handled by Vercel (hosting) and Supabase
• Certificate: Valid SSL/TLS certificates (auto-renewed by providers)

Passwords:

• Hashing: bcrypt with salt (via Supabase Auth)
• Never transmitted in plain text: Always over HTTPS
• No password reset links via email: Magic link authentication used

API Keys & Secrets:

• Storage: Environment variables only (not in code)
• Management: Via Vercel and local .env.local (not committed)
• Format: Secure random strings generated by services

Document Storage:

• Location: Supabase Storage (AWS S3-compatible)
• Encryption: Service-managed encryption available
• Access: Protected by Supabase RLS policies
• User isolation: Each user can only access their own documents

Documents in the system are handled as:

Current:

• Data stored by Supabase (AWS-backed, geographic region configurable)
• Default US region (configurable per customer if on enterprise plan)
• No automatic EU residency (contact support for custom setup)

Future:

• EU data residency options planned
• On-premise deployment options under development

Current Policy:

• Free/Starter: Documents retained until user deletes them
• Professional/Enterprise: Custom retention per agreement

Deletion:

• Users can delete documents anytime via API/dashboard
• Deleted documents removed from active database
• Backups retained per standard schedule (check with Supabase)
• Audit logs may be retained longer for troubleshooting

We take security vulnerabilities seriously. If you discover a vulnerability:

How to Report:

1. Email: security@documentintelligence.com (for current contact, check GitHub profile)
2. DO NOT publicly disclose before we've had time to patch
3. Include: Vulnerability description, impact, proof-of-concept if possible
4. Wait: We commit to responding within 48 hours on a best-effort basis

What Happens Next:

1. We assess and reproduce the vulnerability
2. We develop and test a fix
3. We deploy the patch
4. We notify you and provide credit if you wish
5. We may issue a security advisory

Important: This is not a bug bounty program. We appreciate responsible disclosure but cannot currently offer financial rewards.

How We Manage Dependencies:

• ✅ Regular npm audit checks
• ✅ Dependabot enabled for GitHub
• ✅ Security updates prioritized
• ✅ Monthly dependency audits
• ✅ Version pinning for stability

Third-Party Libraries Used:

• Next.js 14 – Web framework (maintained by Vercel)

• TypeScript – Type safety
• Supabase – Backend (open source, self-hostable)
• Stripe – Payment processing
• shadcn/ui – Component library
• Tailwind CSS – Styling
• React Hook Form – Form handling
• tRPC – Type-safe APIs

All major dependencies are from established, well-maintained projects with active security practices.

Current Status:

• No formal penetration tests scheduled
• No external security audits performed
• Code review happens during pull requests
• Internal security review before deployments

Future:

• Penetration testing may be added as platform grows
• Third-party security audit may be commissioned for enterprise versions

Response Times (Best-Effort):

• Security issues: Response within 48 hours
• Outages: Monitored during business hours (South Africa time)
• Critical bugs: Patched as quickly as possible

Limitations:

• No 24/7 on-call support (this is an MVP)
• No dedicated security operations center
• No formal SLA guarantees
• Uptime depends on Vercel and Supabase availability

When Something Goes Wrong:

1. Detection

   • User reports issue → GitHub issue or email
   • Monitoring alerts (basic error tracking)
   • We investigate and assess severity

2. Response

   • Acknowledge issue within 24 hours
   • Develop and test fix
   • Deploy patch
   • Notify affected users

3. Communication

   • For minor issues: Email to affected users
   • For security issues: May post security advisory
   • For outages: Updates via GitHub status page (when applicable)

4. Post-Incident

   • Document what happened
   • Update systems to prevent recurrence
   • Share learnings with team

Note: We do not have formal incident response team, CISO, or breach insurance at this stage.

User Authentication:

• ✅ Email + password (hashed with bcrypt)
• ✅ OAuth 2.0 (Google, Microsoft via Supabase)
• ✅ Magic link / passwordless (email link auth)
• ✅ Email verification before account access

API Authentication:

• ✅ API key authentication
• ✅ JWT tokens with expiration
• ✅ Per-user rate limiting

Multi-Factor Authentication:

• ⏳ Planned for future (not currently implemented)

User Roles:

• Admin – Full access to organization and settings
• Manager – Can invite users, view reports
• User – Can upload documents, analyze, view own documents
• Viewer – Read-only access to documents

Database Security:

• ✅ Row-level security (RLS) policies enforce user isolation
• ✅ Users can only access their own documents
• ✅ No cross-user data leakage
• ✅ Admin-only operations protected

Request Security:

• ✅ HTTPS required (HTTP redirected)
• ✅ Input validation on all endpoints
• ✅ SQL injection prevention (parameterized queries via Supabase)
• ✅ XSS protection (React escaping)

Rate Limiting:

• ✅ API rate limits per user/API key
• ✅ Limits vary by subscription tier
• ✅ Prevents abuse and DDoS-like behavior

Webhook Security:

• ⏳ Webhook signature verification planned
• ✅ HTTPS-only webhook delivery

What We Log:

• ✅ Authentication events (login, logout, failures)
• ✅ Document uploads and analysis
• ✅ API usage
• ✅ Error messages and stack traces
• ✅ Database access (via Supabase RLS)

Retention:

• Development/staging: Logs kept indefinitely
• Production: Dependent on provider (Supabase, Vercel)

What We DON'T Log:

• ❌ Passwords or API keys
• ❌ Sensitive document content (only metadata)
• ❌ Personal user data beyond what's necessary
• ❌ Full request/response bodies for sensitive operations

Hosting:

• ✅ Vercel (managed hosting, automatic scaling)
• ✅ Supabase (managed PostgreSQL, encrypted storage)
• ✅ Stripe (PCI-compliant payment processing)

Not Self-Hosted:

• No on-premise deployment yet
• No private cloud option yet
• Planned for future enterprise versions

Infrastructure:

• Vercel – App hosting (managed by Vercel, infrastructure security their responsibility)
• Supabase – Database & auth (PostgreSQL, open-source backend)
• AWS – Cloud infrastructure (via Supabase and Vercel)

Services:

• Stripe – Payment processing (PCI-DSS compliant, third-party security)
• OpenRouter – LLM API (third-party service, security depends on OpenRouter)

Libraries & Frameworks:

• See package.json for complete list
• All major dependencies are from established projects
• Dependency updates handled via npm and Dependabot

We are responsible for:

• ✅ How we use these services (securely)
• ✅ Protecting API keys and credentials
• ✅ Securing our code and configuration
• ✅ Encrypting data in transit

Third-party providers are responsible for:

• ✅ Their own infrastructure security
• ✅ Their compliance and certifications
• ✅ Data protection on their systems

Important: Using third-party services means you also trust their security practices. Review their security documentation (Stripe, Supabase, etc.) if handling sensitive data.

Password Security:

• ✅ Use a strong, unique password (12+ characters)
• ✅ Use a password manager (Bitwarden, 1Password, LastPass)
• ✅ Enable passwordless login if available (magic links)
• ❌ Don't reuse passwords across services
• ❌ Don't share your password with anyone

API Key Management:

• ✅ Treat API keys like passwords – keep them secret
• ✅ Store in environment variables, never in code
• ✅ Rotate keys periodically
• ✅ Use different keys for different applications/environments
• ✅ Delete unused keys
• ❌ Never commit keys to version control
• ❌ Never share keys via email or chat
• ❌ Never put keys in logs or error messages

When Using Our API:

✅ DO:
- Use HTTPS for all requests
- Validate SSL certificates
- Implement exponential backoff for retries
- Store credentials securely (env vars, secrets manager)
- Validate webhook signatures
- Rate-limit your requests
- Handle errors gracefully
- Log API calls for debugging

❌ DON'T:
- Hardcode credentials in code
- Log sensitive data (passwords, keys, PII)
- Trust user input without validation
- Use HTTP for sensitive data
- Retry indefinitely
- Store credentials in cookies
- Share credentials via communication channels
- Rely on security through obscurity

When Uploading Documents:

• ✅ Review what you're uploading (avoid unnecessary sensitive data)
• ✅ Use HTTPS (browser will enforce this)
• ✅ Keep your login secure (strong password, don't reuse)
• ✅ Be aware data is stored on our servers
• ❌ Don't upload documents you don't have permission to upload
• ❌ Don't upload unencrypted sensitive data without understanding the risks
• ❌ Don't assume uploads are permanent (follow retention policy)

Regularly Check:

• Review active sessions
• Check login history for unauthorized access
• Verify API keys in use
• Review team members and permissions
• Check billing and subscription status
• Verify email address is current and correct

These are aspirations, not commitments. Timeline and resources dependent on business needs:

Important: These are not commitments. They may not happen, or timelines may change based on business priorities.

Once certifications are pursued:

• SOC 2 Type II – Third-party audit of security controls
• ISO 27001 – Information security management system audit
• GDPR Audit – Legal review of data handling practices
• HIPAA – Healthcare-specific data protection requirements

None of these are currently in progress or planned with external vendors.
