## Overview

SecureShare is an enterprise cybersecurity platform centered on private file sharing: users upload encrypted files, and recipients access them through policy-checked, logged downloads. The browser performs zero-knowledge encryption and signing; backend APIs manage files and security controls. Separate product branches provide threat detection, DLP, SIEM/SOC, IAM, compliance, cloud security, DevSecOps, AI assistance, and platform operations. The graph combines README-documented capabilities with relationships shown in sampled source and the SOURCE INDEX; unsampled subsystems are represented by their existing directories, with uncertain wiring omitted.

Main entry points: [`backend/server.js`](https://github.com/shanidhya01/secureshare/blob/main/backend/server.js) (API server), [`backend/controllers/file.controller.js`](https://github.com/shanidhya01/secureshare/blob/main/backend/controllers/file.controller.js) (File workflows), [`backend/services/siem/siemLogger.js`](https://github.com/shanidhya01/secureshare/blob/main/backend/services/siem/siemLogger.js) (Event logging), [`frontend/app`](https://github.com/shanidhya01/secureshare/tree/main/frontend/app) (SecureShare UI)
