How it works

Offline-First Architecture

A hardened, layered system ensuring complete operational continuity — air-gapped networks, flights, or remote locations. Your data is always local first.

Uncompromising Security

Military-Grade Cryptographic Vault

Your secrets never touch disk in plaintext. Horizon's vault engine applies AES-256-GCM authenticated encryption with a PBKDF2-SHA256 key derivation function at 210,000 iterations — well above NIST and OWASP recommendations.

AES-256-GCM

Authenticated encryption with built-in integrity verification for every stored secret.

210,000 PBKDF2 Iterations

Key stretching far exceeds industry standard requirements, making brute-force attacks computationally infeasible.

Independent Master Key

Vault credentials are fully decoupled from login passwords — changing your account password never exposes secrets.

Zero-Downtime Key Rotation

Rotate master passphrases at any time. Horizon decrypts and re-encrypts all secrets in-memory with zero data loss.

Always in Sync

5 Enterprise Cloud Backends

Horizon's pluggable connector architecture synchronizes your data to whichever cloud backends your organization already uses — every 3 minutes, automatically.

MongoDB Atlas

Full document collections sync with GridFS binary document storage for large file attachments and evidence.

Native BSON

Google Drive

Personal and Google Workspace sync with zero-dependency loopback OAuth 2.0 on http://127.0.0.1:8585.

v3 API / Loopback OAuth

SharePoint Online

Enterprise SharePoint Lists and Shared Document Libraries sync via REST / MSAL authentication.

REST / MSAL

OneDrive for Business

Standard organization folder sync to /HorizonPM/Documents via Microsoft Graph API.

Graph API

Azure Key Vault

Hardware Security Module (HSM) integration to browse, reveal, and rotate cloud secrets inline within Horizon's UI.

Azure SDK

Automated Delta Sync

Background sync agent runs every 3 minutes. Deterministic last-write-wins conflict resolution with full audit logging. Never worry about stale data.

Questions & Answers

Frequently Asked Questions

Is Horizon PM really free?
Yes. Horizon PM is 100% free and open-source under the Apache License 2.0. You can download, use, and modify it for commercial purposes with proper attribution.
Does it work without internet?
Absolutely. Horizon is built on an offline-first SQLite WAL database. All core functionality works completely offline. Cloud synchronization is optional and runs in the background when connectivity is available.
Which operating systems are supported?
Currently, Horizon PM officially ships for Windows (64-bit). The application is built with Electron and could theoretically run on macOS and Linux — community contributions for those platforms are welcome.
How secure is the secrets vault?
The vault uses AES-256-GCM authenticated encryption with PBKDF2-SHA256 key derivation at 210,000 iterations — significantly exceeding NIST SP 800-132 and OWASP recommendations. Plaintext secrets never touch disk.
Can I use my existing cloud storage?
Yes. Horizon supports MongoDB Atlas, Google Drive, Microsoft SharePoint Online, OneDrive for Business, and Azure Key Vault as sync backends. You can mix and match, or use none at all.
How do I get started?
Download the latest installer from our GitHub Releases page. After installation, Horizon creates a default admin account (username: admin, password: horizon123). Change your password on first login.
Can I contribute to the project?
Absolutely! Fork the repository on GitHub, create a feature branch, and open a pull request. Please review our Contributing Guidelines and Code of Conduct before submitting.
