Is fail2zig worth running as a client service?

fail2zig is an open-source, single-binary fail2ban replacement that supports agencies delivering managed Linux intrusion prevention, with durable SQLite state and kernel-level ban enforcement. Vendor pricing, labor costs, client rates, and expected volume are not supplied, so ROI cannot be modeled from the evidence.
