Denyhosts Alternatives

Denyhosts is described as 'The idea of denying access to SSH servers is nothing new and I was inspired by many other scripts that I discovered. However, none of them did things the way I envisioned them to. Also, they were all shell scripts which do not offer the elegance of Python' and is an app in the network & admin category. There are more than 10 alternatives to Denyhosts for a variety of platforms, including Linux, Windows, Self-Hosted, Mac and Web-based apps. The best Denyhosts alternative is CrowdSec.

    Software has been set open-source and abandoned by the main developer. Seems a very good detector but fails to successfully stop attacks. When I have it set to block IPs after 5 failed attempts I shouldn't see multiple entries showing 300 attempts by the same IP addresses.
