SecAI vs fail2ban: a managed, autonomous step up
fail2ban is a dependable classic. It watches logs and bans IPs after failed attempts. SecAI does that too, and then keeps going, without you editing a jail on every server.
Written by the team that builds SecAI. We have tried to be specific enough about where fail2ban wins that you can check the claims.
fail2ban reads log files, matches failure patterns, and adds firewall rules to ban the source for a while. It is free, battle-tested, and runs locally on each host. You configure the jails, the filters, and the ban times, per server.
SecAI blocks the same attackers, using fail2ban under the hood, but centrally and automatically across your whole fleet, with no per-host jail editing. On top of blocking it adds AI security audits, DDoS and web-attack detection, compliance reports, a dashboard, and self-healing fixes.
The trade is familiar: fail2ban is free and entirely yours to configure and maintain on each box. SecAI is a managed layer that includes that blocking and removes the per-server config work.
fail2ban vs SecAI, side by side
| fail2ban | SecAI | |
|---|---|---|
| Core job | Ban IPs after failed logins, from logs | Detect, block, audit, and self-heal |
| Setup | Configure jails and filters per host | One install command per server |
| Managed centrally | No, per-host config files | Yes, one dashboard for the fleet |
| Beyond SSH / brute force | Add filters yourself | DDoS, web attacks, webshells, built in |
| AI security audits | No | Yes, scored, with one-click fixes |
| Self-healing fixes | No | Yes, applies and rolls back on its own |
| Self-lockout protection | You manage ignoreip yourself | Your IPs auto-exempted, cannot lock you out |
| Compliance reports | No | One-click NESA / PDPL PDFs |
| Cost | Free | Paid subscription |
Where fail2ban wins
- Free and everywhere. fail2ban is on nearly every distro, costs nothing, and has years of proven use behind it.
- Fully local. It runs on the host with no external service, which some environments require.
- Simple and predictable. For one server and a narrow job (ban SSH brute-force), it is hard to beat on simplicity.
Where SecAI wins
- No per-host config. SecAI blocks across the whole fleet automatically, so you are not editing jails on every server.
- Much more than brute-force. DDoS, web attacks, webshells, AI audits, and compliance reports are all outside what fail2ban does.
- Safe by default. Your own IPs are auto-exempted, so an aggressive rule can never lock you out of your own server.
- Self-healing. If a fix SecAI applies breaks a service, it rolls the change back on its own and tells you.
Choose fail2ban if you want a free, local, single-purpose IP banner on one or two servers and are happy to configure it. Choose SecAI if you want that blocking managed across a fleet, plus audits, DDoS protection, reports, and self-healing.
