wasabielements/susshi-proxy repository overview

⁠suSSHi Gateway

This repository contains the suSSHi Gateway (susshid) and the optional suSSHi Proxy (susshi-proxyd) — the SSH gateway and proxy daemons of the suSSHi Suite.

⁠Overview

suSSHi is an enterprise-grade SSH gateway suite that makes SSH access auditable, policy-driven and centrally managed across data center and cloud environments. It places a single, RFC-compliant entry point in front of your SSH infrastructure and adds centralized authentication, fine-grained access control, protocol inspection and full session recording — without requiring changes to SSH clients or target servers.

Because every connection passes through the gateway, firewall rules stay simple and target servers never need to be exposed to clients directly.

• Centralized SSH gateway — one point of access for SSH connections to many targets
• Session management — full session recording, live monitoring and replay
• Authentication — public key, agent forwarding, multi-factor and OIDC
• Protocol inspection — deep inspection of SSH, SCP, SFTP, X11 and TCP forwarding
• Access control — users, roles and access policies managed centrally
• REST API — full programmatic control over configuration and session context

⁠Components

The suSSHi Suite consists of the following components:

⁠Architecture

⁠Documentation

The complete suSSHi manual — installation, configuration, administration and troubleshooting — is published online only:

https://docs.susshi.io⁠

This repository deliberately keeps no separate documentation. The online manual is the single source of truth and always reflects the current release.

⁠Release Notes

There is no changelog in this repository. Release notes for all suSSHi components, including the recommended upgrade paths, are published online:

https://docs.susshi.io/release_notes/index.html⁠

⁠Reporting Bugs & Security Issues

⁠Bugs and feature requests

Please open an issue in the repository of the affected component (see Components⁠). Include the component version, your deployment setup and, where possible, steps to reproduce.

⁠Security vulnerabilities

Please do not report security vulnerabilities through public issues.

Instead, send an e-mail to [email protected]⁠ with:

• A description of the vulnerability
• Steps to reproduce or a proof of concept
• Your assessment of the potential impact

We aim to acknowledge reports within two business days and will keep you informed while we work on a fix. We follow coordinated disclosure: once a fix is available we publish a security advisory and credit the reporter, unless they prefer to remain anonymous. Security fixes are applied to the latest release, so we recommend always running the most recent version.

⁠Enterprise Edition & Subscription

suSSHi Gateway, suSSHi Proxy, the suSSHi Chef core and suSSHi Sous Chef are fully open source under the AGPL-3.0-or-later — fully transparent, and complete enough to run standalone without a subscription.

Beyond that, suSSHi Chef can load a separate, proprietary Enterprise Edition — a Rails engine that is not part of these repositories and is not licensed under the AGPL.

The Enterprise Edition and commercial support are not sold separately: a single suSSHi subscription covers both. It is issued per installation, valid for a fixed term, and unlocks the licensed features along with the user and target limits it was signed for.

But production environments require more than code. A subscription includes:

• The Enterprise Edition with additional features like suSSHi Proxy, Audit log file encryption, dynamic OTP target authentication (DOTP) and target fusions.
• Priority e-mail support and issue handling
• Direct access to core maintainers
• Bug investigation and guidance
• Custom feature development
• Long-term stability and roadmap influence

If you use suSSHi commercially, a subscription also helps ensure its long-term sustainability. Open source gives you freedom. Our subscription gives you certainty.
