Profile

Built fail2zig because I like fail2ban's log-to-ban model but wanted a smaller runtime with explicit limits on the work attacker controlled input can cause.fail2zig is a single static binary with bounded parsers instead of a regex engine, SQLite-backed durable state, and nftables enforcement directly through netlink. Also has the ability to inspect and migrate existing fail2ban configurations.I just release 0.4.0 today which is the point where I'm more comfortable putting it in front of more people.Source: https://github.com/ul0gic/fail2zigWouldn't mind feedback from people running fail2ban today, including reasons you would not switch.
