Which hosting have firewall to prevent to attack ?

Last I buy week hostwinds hosting and then i install wordpress on my domains after 2 days site are hacked due to their low firewall. Now what I need to do

Did you use nulled themes or plugins? Did you use the same password you use on other services? Was the hack through the hosting account itself, or the WP login, or through a backdoored WP script?

I personally use WPS Hide Login and WordFence, though these will not help at all if the issue is with your hosting or backdoored scripts.
