CORTEX Platform
CORTEX is a multi-tenant SaaS business management platform built for enterprises that need secure, scalable, and compliant operations management.
What is CORTEX?
CORTEX provides the foundational infrastructure every SaaS application needs:
- Multi-Tenancy — Complete data isolation between tenants with Row Level Security
- Authentication — JWT-based auth with token rotation, session management, and account lockout protection
- Authorization (RBAC) — Hierarchical role-based access control with permission inheritance
- Organization Management — Nested organizational hierarchy within tenants
- User Management — Complete user lifecycle from registration to deactivation
- Audit Logging — Immutable, queryable audit trail for compliance
- Error Handling — RFC 7807 Problem Details for consistent error responses

Key Design Principles
| Principle | Implementation |
|---|---|
| Zero Trust | Every request is authenticated and authorized |
| Tenant Isolation | Cross-tenant access returns 404 (not 403) to prevent information leakage |
| Immutable Audit | All changes are logged and cannot be modified |
| RFC Compliance | Error responses follow RFC 7807 Problem Details |
| Enterprise Grade | No hardcoded values, configurable via environment |
