It seems that SSHGuard has been updated to version 2 for Linux, MacOS and BSD family of operating systems to protect your OpenSSH server from hackers and bad people on the internet. I find added support for firewalld backend is nice way to support your Fedora server in cloud.
From the blog post:
Three new firewall backends for Linux, Capsicum sandboxing and capability support on *BSD, and an easier configuration scheme. The newly released SSHGuard 2.0.0 makes it easier than ever to protect your SSH service on anything from an underpowered Raspberry Pi 2/3 to enterprise servers.
