Complete Guide to Setting Up a Private Company Server in 2025
Everything you need to set up a private company server: hardware selection, Proxmox installation, Docker, networking, security, monitoring, and 50+...
Why Every Company Needs a Private Server
In the age of cloud, running your own server sounds old-school. But it's actually the smartest infrastructure decision many companies can make:
Server infrastructure: production and staging environments connected via VLAN with offsite backups.
- Cost: 60-80% cheaper than AWS/GCP/Azure
- Control: Full root access, no vendor restrictions
- Privacy: Data never leaves your premises
- Performance: Dedicated resources, no noisy neighbors
- Sovereignty: Meet compliance requirements (GDPR, HIPAA, data residency)
Hardware Selection
For a 10-50 person company:
Option 1: Repurposed Laptop ($0-500)
- Any modern laptop with 16-32GB RAM
- Perfect for starting out
- We use an ASUS FX505DT (Ryzen 5, 16GB, 512GB NVMe + 1TB HDD)
Option 2: Mini PC ($300-800)
- Intel NUC or Beelink mini PCs
- Silent, energy-efficient (~25W)
- Great for office deployment

Docker + Docker Compose inside an LXC container
- Lightweight, efficient
- Single management point
- Easy backup and restore
Layer 3: Networking
Cloudflare Tunnel (free)
- Zero open ports
- DDoS protection
- Automatic SSL
Traefik v3 (reverse proxy)
- Docker label-based routing
- Automatic service discovery
- Middleware chains for auth
Layer 4: Security
Authelia (SSO, 2FA)
- Single sign-on for all services
- Role-based access control
- OIDC identity provider
CrowdSec (intrusion prevention)
