IPBan
Prevents unauthorized access and secures IP addresses for network protection.
Our take: IPBan is a free, MIT-licensed security daemon (not a SaaS) that monitors event logs and log files to detect brute-force login attempts and automatically bans offending IPs via OS-level firewall rules.
The go-to free, self-hosted brute-force blocker for sysadmins who want zero licensing cost and full control.

Our takeIPBan is a free, MIT-licensed security daemon (not a SaaS) that monitors event logs and log files to detect brute-force login attempts and automatically bans offending IPs via OS-level firewall rules.
Why we rate itFifteen-plus years of active development, cross-platform (Windows & Linux), and zero cost for the core use case make IPBan uniquely practical for budget-conscious sysadmins.
Best / not good for
- Sysadmins hardening VPS/dedicated servers against RDP and SSH brute force
- Small teams needing zero-cost automated IP banning on Windows or Linux
- Homelabs and SMBs that can't justify enterprise WAF or CDN-level DDoS tools
- Organizations needing a managed cloud security service with zero server setup
- Teams wanting DDoS protection or Layer 3/4 volumetric attack mitigation
- Environments requiring a central UI across dozens of servers without buying IPBan Pro
Friction report
Trade-offs to know before signing up.
- Time to valueModerate: download and run the binary, edit XML config for thresholds — protected within 15–30 minutes for experienced sysadmins; steeper for newcomers.
- Scale breakpointManaging rules across many servers requires IPBan Pro's paid web console; the free version is per-server with no centralized orchestration.
- Walled gardenLow: MIT-licensed OSS with standard firewall rule output; no proprietary data formats and no vendor lock-in.
