Efficient, reliable way to secure WordPress

I trialled Really Simple SSL for a while and then purchased Pro for a couple of WordPress sites. Pro has been running for a couple of years now on each WP site and I’ve watched progress over a decent amount of time. I highly recommend using RS-SSL Pro on your WP sites. It takes care of a lot of your security headers, SSL settings etc. My WP sites already have SSL installed but this plugin adapted seamlessly and it provides peace of mind. I’d recommend both Basic and Pro any day. A default Pro plugin for all WP sites now. Well worth the nominal $ outlay.
