Cannot recommend more highly
Wordfence is an intuitive and powerful plugin with stellar support. They are continuously updating it and communicating with end users. They have helped me through a hack (It was my fault--not a failed firewall) and the bazillion questions (for weeks) that followed. They have helped me through ensuring my test site is secure. The engineers are thorough, knowledgable, and responsive. I have the Premium version and highly recommend. I cannot recommend Wordfence more highly.
