About
Fail2zig is a single static binary reimplementation of fail2ban's log-to-ban model, written in Zig to bound the work that attacker-controlled log input can trigger. It replaces fail2ban's regex engine with bounded parsers, stores state durably in SQLite, enforces bans directly through nftables via netlink, and can inspect and migrate existing fail2ban configurations.
Why it made the leaderboard
Replaces fail2ban's regex-driven log parsing, a known ReDoS-style risk since it processes attacker-controlled input, with bounded parsers in a single static binary, shrinking that tool's own attack surface.
