Complete guide to choosing the best VPS provider in 2025 (Hetzner, DigitalOcean, Linode, Vultr) and essential security hardening steps for your new server.

If you're a developer looking to host your projects, run a business application, or just want more control over your hosting environment, a Virtual Private Server (VPS) is the way to go. After years of using various cloud providers, I've settled on my preferred choice and learned some crucial security practices along the way.
In this guide, I'll share my experience with different VPS providers, why I chose Hetzner, and the essential security steps you should take immediately after spinning up a new server.

Why VPS Over Shared Hosting or PaaS?#

Before we dive in, let me explain why I prefer VPS:

  • Full Control: Root access means you can install anything, configure everything
  • Cost Effective: For the same price as a managed service, you get significantly more resources
  • Learning Opportunity: Managing your own server teaches you invaluable DevOps skills
  • No Vendor Lock-in: Your setup is portable across providers

Best VPS Providers in 2025#

After testing multiple providers over the years, here's my honest comparison:

Hetzner (My Choice)#

Hetzner is a German hosting provider that has become incredibly popular among developers for good reason. They offer some of the cheapest bare-metal servers and cloud instances in Europe, and their US locations are equally competitive.
Pros:

  • Best price-to-performance ratio in the market
  • AMD EPYC Genoa processors (refreshed October 2025) with ~30% better performance
  • Starting at just €3.49/month for cloud servers
  • Excellent uptime and reliability
  • Data centers in Germany, Finland, Netherlands, USA, and Singapore

Cons:

  • Limited managed services (but that's fine if you know what you're doing)
  • Traffic allowance varies by region (20TB in EU, 1TB in US, 500GB in Singapore)

DigitalOcean#

Best for: Beginners and those who need managed services
Starting at $6/month, DigitalOcean offers a beginner-friendly interface with managed databases, Kubernetes clusters, and load balancers. However, you pay extra for every managed service.

Linode (Akamai)#

Best for: Predictable billing and enterprise reliability
Linode offers the best balance of price/performance with clear pricing and a large global footprint. Great customer support and "boring" stability—which is exactly what you want in production.

Vultr#

Best for: Global SaaS applications requiring low latency everywhere
With 30+ data centers worldwide, Vultr excels at global reach. They offer high-frequency compute options and bare metal instances for demanding workloads.

Why I Chose Hetzner#

For my projects, Hetzner hits the sweet spot. I'm running multiple applications including web servers, databases, and background workers. With Hetzner's CPX21 plan (3 vCPUs, 4GB RAM, 80GB SSD), I pay around €8/month for resources that would cost $30+ elsewhere.
The performance is outstanding—their AMD EPYC processors handle my Node.js applications and PostgreSQL databases without breaking a sweat.

Getting Started with Hetzner#

Ready to spin up your first VPS? Here's how:

  1. Sign up: Create your Hetzner account here (you'll get €20 free credits)
  2. Go to Cloud Console: https://console.hetzner.com
  3. Click "Add Server" → Choose your location (I recommend Falkenstein or Nuremberg for EU, Ashburn for US)
  4. Select an image: Ubuntu 24.04 is my go-to
  5. Choose a plan: CPX11 (€4.85/mo) is great for starting out
  6. Add your SSH key (we'll set this up in the security section)
  7. Create & Deploy

Your server will be ready in under a minute.

First Things to Do After Getting Your VPS#

This is where most people make mistakes. A fresh VPS is essentially an open door to attackers. Here's my checklist for the first hour:

1. Update Everything Immediately#

Bash
1# Ubuntu/Debian
2sudo apt update && sudo apt upgrade -y
3
4# CentOS/RHEL
5sudo dnf update -y

2. Create a Non-Root User#

Never use root for daily operations. Create a dedicated user:

Bash
1# Create new user
2adduser deploy
3
4# Add to sudo group
5usermod -aG sudo deploy
6
7# Switch to new user
8su - deploy

3. Set Up SSH Key Authentication#

Password authentication is vulnerable to brute-force attacks. SSH keys are significantly more secure:

Bash
1# On your LOCAL machine, generate a key pair if you don't have one
2ssh-keygen -t ed25519 -C "your_email@example.com"
3
4# Copy your public key to the server
5ssh-copy-id deploy@your_server_ip

4. Disable Root Login and Password Authentication#

Edit your SSH config:

Bash
1sudo nano /etc/ssh/sshd_config

Make these changes:

Text
1PermitRootLogin no
2PasswordAuthentication no
3PubkeyAuthentication yes

Restart SSH:

Bash
1sudo systemctl restart sshd

Important: Keep your current session open and test the new configuration in a new terminal before closing!

5. Configure the Firewall (UFW)#

Only allow the ports you actually need:

Bash
1# Enable UFW
2sudo ufw default deny incoming
3sudo ufw default allow outgoing
4
5# Allow SSH (use your custom port if changed)
6sudo ufw allow 22/tcp
7
8# Allow HTTP and HTTPS
9sudo ufw allow 80/tcp
10sudo ufw allow 443/tcp
11
12# Enable the firewall
13sudo ufw enable
14
15# Check status
16sudo ufw status verbose

6. Change the Default SSH Port (Optional but Recommended)#

This significantly reduces automated attacks:

Bash
1sudo nano /etc/ssh/sshd_config

Change:

Text
1Port 2222  # Choose any port between 1024-65535

Don't forget to update your firewall:

Bash
1sudo ufw allow 2222/tcp
2sudo ufw delete allow 22/tcp
3sudo systemctl restart sshd

7. Install and Configure Fail2Ban#

Fail2ban automatically bans IPs that show malicious behavior:

Bash
1sudo apt install fail2ban -y
2
3# Create local config
4sudo cp /etc/fail2ban/jail.conf /etc/fail2ban/jail.local
5sudo nano /etc/fail2ban/jail.local

Add or modify:

Text
1[sshd]
2enabled = true
3port = 2222  # Your SSH port
4filter = sshd
5logpath = /var/log/auth.log
6maxretry = 3
7bantime = 3600
8findtime = 600

Start fail2ban:

Bash
1sudo systemctl enable fail2ban
2sudo systemctl start fail2ban

8. Enable Automatic Security Updates#

Bash
1sudo apt install unattended-upgrades -y
2sudo dpkg-reconfigure --priority=low unattended-upgrades

Best Practices for Ongoing Security#

Regular Backups#

Always have backups. Hetzner offers automated backups for a small fee, or you can set up your own with rsync or restic:

Bash
1# Example: Daily backup to external storage
2rsync -avz --delete /var/www/ user@backup-server:/backups/www/

Monitor Your Server#

Set up basic monitoring to catch issues early:

-htop for real-time resource monitoring-netdata for beautiful dashboards-logwatch for daily log summaries

Use Docker for Isolation#

Running applications in Docker containers adds an extra layer of security:

Bash
1# Install Docker
2curl -fsSL https://get.docker.com -o get-docker.sh
3sudo sh get-docker.sh
4
5# Add your user to docker group
6sudo usermod -aG docker deploy

Keep Everything Updated#

Set a reminder to check for updates weekly:

Bash
1sudo apt update && sudo apt list --upgradable

Use SSL/TLS Everywhere#

I use Caddy as my reverse proxy because it handles SSL automatically—no certbot configuration needed:

Bash
1# Install Caddy
2sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https curl
3curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
4curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
5sudo apt update
6sudo apt install caddy

Caddy automatically provisions and renews SSL certificates. Your Caddyfile is dead simple:

Text
1yourdomain.com {
2    reverse_proxy localhost:3000
3}

That's it. HTTPS just works.

My Current Setup#

For reference, here's what I'm running on my Hetzner VPS:

  • OS: Ubuntu 24.04 LTS
  • Web Server: Caddy as reverse proxy (automatic SSL, zero config)
  • Applications: Multiple Node.js apps via PM2
  • Database: PostgreSQL 16
  • Containerization: Docker for isolated services
  • CI/CD: GitHub Actions for automated deployments
  • Monitoring: Netdata / custom alerts / Uptime Kuma

This setup has been rock solid for months with 99.9%+ uptime.

Conclusion#

Choosing the right VPS provider and securing it properly from day one saves you countless headaches down the road. Hetzner has been my go-to choice for over a year now, and I couldn't be happier with the price-to-performance ratio.

Remember: security is not a one-time setup but an ongoing process. Keep your systems updated, monitor your logs, and stay informed about new vulnerabilities.
