tallow is described as 'Tallow is a fail2ban/lard replacement that uses systemd's native journal API to scan for attempted ssh logins, and issues temporary IP bans for clients that violate certain login patterns' and is an app in the security & privacy category. There are five alternatives to tallow for Linux, Self-Hosted and Windows. The best tallow alternative is Fail2ban, which is both free and Open Source. Other great apps like tallow are reaction, SpyLog, Pyruse and win2ban.
Fail2ban scans log files (e.g. /var/log/apache/error_log) and bans IPs that show the malicious signs -- too many password failures, seeking for exploits, etc. Generally Fail2Ban is then used to update firewall rules to reject the IP addresses for a specified amount of time...
Light-weight and extra-configurable peruser of systemd journal logs: ban IP, send immediate email, daily report… all based on a single JSON configuration file.
win2ban is a Fail2ban implementation for Windows systems. It is a packaging of Fail2ban, Python, Cygwin, Winlogbeat and many other related tools to make it a complete and ready-to-use solution for brute-force attack protection.

It's a completely separate program from tallow, and has none of the features in common.
