What does the "Enhanced" version add?

A hardened, production-ready configuration: tuned ban durations and detection windows, log reading via systemd, and SSH protection enabled from installation.

Do I have to choose between fail2ban and CrowdSec?

No, they are complementary. fail2ban acts locally and simply; CrowdSec adds collaborative threat intelligence. Many servers run both.

Harden infrastructure security.

fail2ban watches the logs of your services and automatically bans, through the firewall, the IP addresses that pile up failed authentication attempts. It is the first line of defence — simple and proven — against brute-force attacks on SSH and exposed services.

This template goes beyond the default install: it deploys a production-hardened configuration (tuned detection windows and ban durations, log reading via systemd, SSH protection enabled from the start). Lightweight and with no web interface, it installs in seconds and protects your server immediately — ideally as a complement to CrowdSec and a hardened bastion.

Key features

Automatic IP banning after repeated authentication failures

Hardened, production-ready configuration (tuned bantime/findtime)

SSH protection enabled from installation

Log reading via systemd (a modern, reliable backend)

Very lightweight — no web interface, minimal memory footprint

Complementary to CrowdSec for defence in depth

When to use this solution?

1

Protect SSH

Automatically block brute-force attacks on the SSH port, the most common target on exposed servers.

2

Harden a web server

Extend the rules to Nginx or Apache logs to ban scans and exploitation attempts.

3

Defence in depth

Combine fail2ban (local) with CrowdSec (collaborative) and a hardened bastion for several layers of protection.

Deploy Fail2Ban Enhanced on your VPS

Guide optimized for ServOrbit Cloud VPS.

01

Create the VPS

A VPS with 512 MB RAM is enough, Ubuntu 22.04. The template installs fail2ban with a hardened jail.local and SSH protection active.

02

Check the status

Check with fail2ban-client status then fail2ban-client status sshd: the SSH jail should be active and watching the logs.

03

Extend the protections

Enable additional jails (nginx, apache, postfix…) in /etc/fail2ban/jail.local according to the services you host.

04

Tune the thresholds

Adjust bantime, findtime and maxretry to your tolerance, and add your trusted IPs to ignoreip.

Frequently asked questions

fail2ban is a security tool that watches logs and automatically bans, through the firewall, the IP addresses responsible for repeated failed authentication attempts.

No, fail2ban is administered from the command line (fail2ban-client). It is a very lightweight service, with no exposed web port.
