Quick Start

Get your server secured with Tetsu VPS in under 5 minutes.

Prerequisites

  • Ubuntu 24.04 LTS server with SSH access (port 22)
  • Root or sudo privileges

3-Step Process

1. Install Agent on Your Server

SSH into your server and run:

curl -fsSL https://tetsuvps.com/api/setup/install | bash

This creates the necessary users for security scanning and hardening.

2. Add Server to Dashboard

  1. Go to Servers → "Add New Server"
  2. Enter:
    • Server Name: Any friendly name
    • IP Address: Your server's public IP
  3. Click "Add Server"

3. Run Security Scan

  1. Go to Scans → "Start Security Scan"
  2. Select your server and scan type:
    • Operating System - Comprehensive security audit
    • SSH - SSH configuration check
    • Webserver - Web server security
  3. Click "Start Scan"

Within 2-3 minutes the scan should complete and display you the results.

Optional: Apply Automated Hardening

⚠️ CRITICAL WARNING: Read Before Hardening

Before applying any hardening, you MUST read the Security Hardening Prerequisites documentation.

Hardening makes irreversible changes that can permanently lock you out of your server if not prepared properly:

  • SSH Hardening will disable root login and password authentication completely
  • You MUST have a non-root user with SSH key access set up BEFORE hardening
  • Always create a full server backup/snapshot before hardening
  • Test on a staging environment first

→ Read the full hardening prerequisites and warnings

After reviewing scan results and completing all prerequisites:

  1. Go to Hardening
  2. Select server and hardening type
  3. Click "Start Hardening"
