It's security by obscurity and it will only work until it gets popular and
then intruders will start port scanning before launching the dictionary
attack.

Denyhosts is defense in depth. It creates a situation where you can't try
bad usernames endlessly and you can't try passwords for valid usernames
endlessly.

I for one use it everywhere and can't recommend it enough.
