I'd be surprised if it works for custom services. Fail2ban has to know what's running and haw to have access to its log file to know what is a failed authentication request. The best you can do without log access is to rate limit new tcp connections. But still you should know what's the service behind because 5 new SSH sessions per minute and IP can be reasonable 5 new http1.0 connections likely cannot load a single html page.
