I´been using this plugin for a month and what can I say?
1. It has all basic security you find in many plugins
2. It has an advanced security you dont find all together in the same plugin.
3. Its easy to use, each feature shows the complexity level of the intervention it makes in wordpress so you can measure if you want to turn on or not.
4. It as a great feature that checks if your wordpress code has been changed, useful in cases someone can hack it and insert a code.
I would really recommend it!
