Secure Cloud Storage
End-to-end encrypted file storage with team collaboration and role-based access.
An enterprise-grade, end-to-end encrypted cloud storage platform with team collaboration tools, file versioning, granular role-based access control, and real-time sync — deployed on AWS for global performance.
The Challenge
The client needed a secure alternative to consumer cloud storage for sensitive business documents, with strict access controls and cross-team collaboration — without sacrificing security or auditability.
Our Solution
Built on AWS S3 with client-side AES-256 encryption before upload. Node.js backend handles versioning, access control lists, sharing links with expiry, and real-time activity feeds.
Results Achieved
Over 1TB of sensitive data stored with 100% uptime since launch. Transfer speeds reach 10Gbps on enterprise plans, and the company passed their ISO 27001 audit using the platform's built-in audit logs.
Tech Stack
Key Features Delivered
Every feature built to solve a specific problem and drive measurable outcomes.
Client-Side Encryption
Files are encrypted before leaving the device — the server never sees plaintext data.
File Versioning
Every file change is versioned. Restore any previous version with one click, up to 12 months back.
Role-Based Access
Granular permissions — owner, editor, viewer, commenter — per file, folder, or project workspace.
Collaboration Tools
Real-time comments, @mentions, and activity feeds keep teams aligned without leaving the platform.
Secure Sharing Links
Password-protected, expiry-limited sharing links for external collaboration without creating accounts.
Audit Logs
Complete audit trail of every access, download, and change — timestamped and user-attributed.
