IPBan
Prevents unauthorized access and secures IP addresses for network protection.
The go-to free, self-hosted brute-force blocker for sysadmins who want zero licensing cost and full control.
IPBan — open-source automated IP-blocking daemon for Windows and Linux servers.
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. DB labels it 'Free Trial' with price_tier 'free_trial', which is incorrect — the core tool is fully free and open source with no trial expiry. A paid IPBan Pro tier exists (~$2.40/mo per server) that adds a web management console, global blocklists, and Windows Filtering Platform integration, making the true model freemium.
Fifteen-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. The Pro tier adds genuine enterprise value without vendor lock-in.
Self-hosted only — no cloud dashboard on the free tier, requires server access and manual configuration, and relies on OS firewall rules rather than network-layer blocking.
