Wordpres

It's very good

Wordpress Better Security Plugin, Site SSL, Cloudflare and Recaptcha nocaptcha this should be enough

no need security plugin, just keep update your plugins.
anyway, use less plugins as possible

I find that server firewalls are usually enough but if you want to be extra safe I would recommend wordfence.

Wordfence Security is very good !

One of the best security plugins for wp is "all in one security and firewall"

Muito boa a segurana para o site e tambm ajuda muito as pessoas no dia

Does anyone know how I can prevent my wordpress website from bruteforce attack without using plugins?

Better to change wp-admin link first! There are some plugins to do this for you.

Great links to some decent plugins. Im using iThemes at the moment.
