The Brute Force Guardian

Standalone fail2ban install that watches your logs for repeated failed logins and bans offending IPs automatically, with your own IPs whitelisted first.

We install and configure fail2ban — an intrusion-prevention daemon that watches log files for repeated failed logins and other attack patterns, then bans offending IP addresses at the firewall for a configurable period. Jails are enabled for whatever is actually running on your server: SSH almost always, plus web server, mail, or application jails (Apache, Nginx, Postfix, Dovecot, WordPress, Nextcloud) where present. Before anything goes live, your own known-good IP addresses are whitelisted, so you and your staff cannot be locked out by the same system protecting you. We configure email or webhook notifications for bans, run test bans across each jail to confirm it actually catches what it should, and hand over a one-page reference of what's protected by which jail. Custom filters — pattern-matching for application-specific log lines the standard filters don't cover — are a separately quoted addition, and require you to supply log samples showing the exact lines to catch.

What's included

  • fail2ban installation on Debian, Ubuntu, Rocky, or Alpine
  • Jail configuration for services actually running on the server (SSH, web, mail, applications)
  • Mandatory whitelisting of your known-good IPs before any jail goes live
  • Email or webhook notification setup for bans
  • Test bans run across each configured jail
  • One-page reference of what is protected by which jail

FAQ

How fast is delivery?
Standard delivery is 15 weekday hours. Express delivery — 9 weekday hours — costs 25% more.
Can this lock us out of our own server?
No — whitelisting your known-good IPs happens before any jail is enabled. That step is mandatory in every install specifically to prevent it.
Does this cover custom application log formats?
Standard third-party filters cover common services out of the box. Pattern-matching for a log format specific to your own application is a separately quoted addition, and requires you to send us log samples showing the exact lines that need to be caught.
Is this the same as the Linux Server Hardening service?
No — this is standalone fail2ban only. The Linux Server Hardening service includes fail2ban as one component of a broader CIS-baseline pass covering SSH lockdown, patching, and audit logging. Choose this one if fail2ban is all you need.
