VPS Security

Hello everyone,

I currently use GreenCloud VPS for FollowLiker and want to make sure its secure. For now, I've been avoiding logging in to my email just to be safe. Does anyone know how secure these VPS's are? And if they're not, what's the best way to make them secure?

Thanks!

on a seperate note, are you happy with greencloud vps? I am just trying to find a good vps provider
