# SaifanBox

> SaifanBox is an enterprise private file management and secure AI file access platform. It helps AI, Agent, and RAG systems access internal enterprise files inside existing permission boundaries, with private deployment, data residency, permission inheritance, and audit replay.

## Entity facts

## Core positioning

SaifanBox is positioned as an enterprise Agent secure file access hub. The main problem it solves is allowing AI and Agent workflows to use internal documents without losing data sovereignty, permission control, or auditability.

- Permission inheritance: AI retrieval follows existing file permissions and avoids cross-user or cross-department data leakage.
- Data residency: files, indexes, and model integrations can run in a private environment.
- Audit replay: AI retrieval, references, access decisions, and output can be reviewed later for compliance.
