A relative newcomer to the WordPress world (well the last year really) and as a business it is important to me that I have standard plugins that I can use and recommend to my customers, as they just work, and I can relax. WordFence Security is one of the those plugins, that I just cannot see why a user would not have it loaded on their WordPress installation. Its simple to set-up, even with the free version there are a wealth of options and if you do decide to upgrade to the premium version, other goodies are there for use. If you host a WordPress site yourself or, as in my case, for customer, do yourself a favour and install this plugin. You will not be disappointed.
