Hello,
Recently i got an idea in protecting my servers more than enough so what do you recommend? Fail2Ban or DDoS Deflate?

Protecting against what exactly?.. Both tools are just shields against brute-force attacks. If that's what's bothering you then yes, they can be useful. The downside is that they will be eating on your VPS's resources; hence the tough choice.

After reading some information about both of these scripts i see that DDoS deflate is better because its sending emails but i think that i have to setup mail server first.
I didn't post this in VPS Support because its not something connected to my VPS
Tell me your experience with them

Fail2ban can send you an email too if configured!! and that should not be what should motivate you for either one of them. They both look for abusive IPs based on different approaches:
> scanning the logs of predefined services (for fail2ban) or
> periodically running a netstat command via a cron job (for the DDoS defalte script.)

The objective criteria that should tip the scale for one or the other should be how much resources each one of them consumes to get the same job done? and well that job is achieved?

I never(/and hopefully ever) needed them before, but looking at their MO(/modus operandi) I would lean towards the DDoS deflate script as the better one of the two, but would like to see the input of those who did use it on live systems.
